Split-screen display method and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a split-screen display method and an electronic device.

Background

In order to facilitate the operation of the driver, the driver can connect the mobile phone with the vehicle-mounted system. The mobile phone can project the display interface to the vehicle-mounted system so as to achieve the purpose of checking the display interface of the mobile phone through the vehicle-mounted system. According to statistics, the high-frequency scenes of the mobile phone used by the driver in the driving process comprise navigation, call receiving, music listening, call making and the like. The use of a mobile phone during driving will affect driving safety. For example, after the vehicle-mounted system is connected to the mobile phone, the display screen of the vehicle-mounted system displays a navigation interface in the mobile phone. When the mobile phone receives an incoming call, the vehicle-mounted system displays an incoming call interface, and the foreground of the vehicle-mounted system does not display a navigation interface any more. For a driver, the navigation interface on the vehicle-mounted system is invisible due to the fact that the incoming call is received, navigation information cannot be checked, and driving safety is affected.

Currently, the industry proposes to set two display screens on a vehicle-mounted system, where the first display screen is used for displaying navigation and the second display screen is used for displaying interfaces of other applications, such as an incoming call interface. However, the arrangement of two display screens results in higher cost and waste of resources, for example, the second display screen is idle most of the time.

Disclosure of Invention

The application provides a split screen display method and electronic equipment. In the method, the vehicle-mounted system can realize split-screen display, so that the operation of a driver is facilitated, and the driving safety is improved.

In a first aspect, the present application provides a split-screen display method for a vehicle-mounted system, which is applied to an electronic device, where the electronic device is connected to the vehicle-mounted system, and the vehicle-mounted system has a display screen; the method comprises the following steps: the electronic equipment displays a first interface, wherein the first interface comprises a first display interface of a first application, and the first application has a navigation function; the electronic equipment controls the vehicle-mounted system to display a first display interface of the first application; the electronic equipment detects a first input operation; the electronic equipment responds to the first input operation, switches the first application to a background to run, and displays a second interface; the electronic equipment controls the vehicle-mounted system to display in a split screen mode, so that a first display area on the display screen of the vehicle-mounted system displays a first display interface of the first application, and a second display area on the display screen displays a second interface.

For example, the electronic device is connected with the vehicle-mounted system, the electronic device displays a display interface of the map application, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application in a full screen mode (all areas on the display screen of the vehicle-mounted system which can be used for displaying the application interface). When the electronic equipment switches the map application to the background and the foreground displays other interfaces, the vehicle-mounted system is controlled to display in a split screen mode, and the vehicle-mounted system can display the display interface of the map application and the other interfaces at the same time. Therefore, even if the map application is switched to the background by the electronic equipment, the map application is still displayed on the foreground of the vehicle-mounted system, so that a user can check the map conveniently, and the driving safety is improved.

In one possible design, the electronic device detects a second input operation before switching the first application to a background running in response to the first input operation; and responding to the second input operation, and starting a navigation function in the first application.

For example, the electronic device is connected with the vehicle-mounted system, the electronic device displays a display interface of a map application, the map application opens a navigation function, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application. When the electronic equipment switches the map application to the background, the foreground displays other interfaces, and at the moment, the vehicle-mounted system is controlled to display in a split screen mode, so that the vehicle-mounted system can simultaneously display the display interface of the map application and the other interfaces. Therefore, even if the map application is switched to the background by the electronic equipment, the foreground of the vehicle-mounted system still displays the display interface of the map application, so that a user can conveniently check the map, and the driving safety is improved. For another example, the electronic device displays a display interface of the map application, but the map application does not open the navigation function yet, the electronic device is projected to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application in a full screen manner. When the electronic equipment switches the map application to the background and the foreground displays other interfaces, the vehicle-mounted system does not need to be controlled to display in a split screen mode, and the vehicle-mounted system can display the other interfaces in a full screen mode (because the map application does not open the navigation function yet).

In one possible design, the electronic device further detects a third input operation; the electronic equipment responds to the third input operation and switches the first application from a background to a foreground to run; the electronic equipment controls the vehicle-mounted system to exit a split screen mode, so that an area available for displaying an application interface on the display screen of the vehicle-mounted system displays a first display interface of the first application in a full screen mode.

For example, the electronic device runs a map application in a background, displays other interfaces in a foreground, and controls the vehicle-mounted system to display in a split screen mode, that is, the vehicle-mounted system simultaneously displays the display interface of the map application and the other interfaces. When the electronic equipment switches the map application from the background to the foreground, the vehicle-mounted system can be controlled to exit the split screen mode. In the method, even if the map is operated in the background of the electronic equipment, the map application can still be displayed in the foreground by the vehicle-mounted system, so that a driver can conveniently check the map, and the driving safety is improved.

In one possible design, before the electronic device detects a first input operation, the electronic device receives an incoming call and displays incoming call information in the first interface; the electronic equipment detects a first input operation, switches the first application to a background operation, and displays a second interface, including: and detecting a first input operation for answering the incoming call, switching the first application to background operation, and displaying a call interface, wherein the incoming call comprises a video incoming call and/or a voice incoming call.

For example, the electronic device is connected with the vehicle-mounted system, the electronic device displays a display interface of the map application, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application in a full screen mode. When the electronic equipment receives an incoming call, the electronic equipment detects the operation of answering the incoming call, the map application is switched to the background, the foreground displays a call interface (a display interface after successful answering), and at the moment, the vehicle-mounted system can be controlled to display in a split screen mode, so that the vehicle-mounted system can simultaneously display the display interface of the map application and the call interface. Therefore, even if the map application is switched to the background by the electronic equipment, the foreground of the vehicle-mounted system still displays the display interface of the map application, so that a user can conveniently check the map, and the driving safety is improved.

In one possible design, before the electronic device detects the first input operation, the electronic device receives a message, and the message is displayed in the first interface; the electronic equipment detects a first input operation, switches the first application to a background operation, and displays a second interface, including: detecting a first input operation aiming at the message, wherein the first input operation is used for starting a second application corresponding to the message; and responding to the first input operation, switching the first application to background running, and displaying a second display interface of the second application.

For example, the electronic device is connected to the vehicle-mounted system, the electronic device displays a display interface of the map application, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application. When the electronic equipment receives the WeChat/short message, the electronic equipment detects the operation aiming at the WeChat/short message, the map application is switched to the background, the display interface of the WeChat/short message application is displayed on the foreground, and at the moment, the vehicle-mounted system can be controlled to display in a split screen mode, so that the vehicle-mounted system can simultaneously display the display interface of the map application and the display interface of the WeChat/short message application. Therefore, even if the map application is switched to the background by the electronic equipment, the foreground of the vehicle-mounted system still displays the display interface of the map application, so that a user can conveniently check the map, and the driving safety is improved.

In one possible design, the electronic device detects a first input operation, switches the first application to a background running state, and displays a second interface, including: the electronic equipment detects a first input operation, and the first input operation is used for returning to a main interface; and responding to the first input operation, switching the first application to background operation, and displaying the main interface.

For example, the electronic device is connected to the vehicle-mounted system, the electronic device displays a display interface of the map application, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application. When the electronic equipment receives the operation of returning to the main interface, the map application is switched to the background, the foreground displays the main interface, and at the moment, the vehicle-mounted system can be controlled to display in a split screen mode, so that the vehicle-mounted system can simultaneously display the display interface and the main interface of the map application. Therefore, even if the map application is switched to the background by the electronic equipment, the foreground of the vehicle-mounted system still displays the display interface of the map application, so that a user can conveniently check the map, and the driving safety is improved.

In one possible design, the first application may be a mapping application, and the first display interface includes the mapping application, and/or navigation information. The map application may be, but is not limited to, a Baidu map, a Gade map, and the like.

In one possible design, the electronic device acquires display parameters of a display screen of the vehicle-mounted system; and the electronic equipment determines the layout of the first display area and the second display area according to the display parameters.

For example, when the display screen of the vehicle-mounted system is a horizontal screen (the length of the display screen is larger than the width), the electronic device can control the vehicle-mounted system to be divided into two regions in the horizontal direction, and when the display screen of the vehicle-mounted system is a vertical screen (the width is larger than the length), the electronic device can control the vehicle-mounted system to be divided into two regions in the vertical direction.

In one possible design, the layout includes: display areas and display positions of the first display area and the second display area.

In one possible design, the electronic device adjusts the layout of the first display area and the second display area according to the display parameter, including: when the electronic equipment determines that the display screen of the vehicle-mounted system is a transverse screen according to the display parameters, determining that the ratio between the first length of the first display area and the second length of the second display area is a first ratio; the transverse screen is used for indicating that the length of the display screen of the vehicle-mounted system is larger than the width of the display screen; when the electronic equipment determines that the display screen of the vehicle-mounted system is vertical according to the display parameters, determining that the ratio between the first width of the first display area and the second width of the second display area is a second ratio; the vertical screen is used for indicating that the width of the display screen of the vehicle-mounted system is larger than the length of the display screen of the vehicle-mounted system.

For example, when the display screen of the in-vehicle system is a landscape screen (the display screen is larger than wide), the electronic device may control the in-vehicle system to be divided into two regions, the length ratio of the first display region to the second display region may be a first ratio, and the widths of the first display region and the second display region may be the same. When the display screen of the vehicle-mounted system is vertical (wider than long), the electronic device can control the vehicle-mounted system to be vertically divided into two areas, the width ratio of the first display area to the second display area can be a second ratio, and the lengths of the first display area and the second display area can be the same.

In one possible design, the first display area and the second display area occupy all the area available for displaying an interface on a display screen of the in-vehicle system.

For example, when the status bar cannot be hidden on the display screen of the in-vehicle system, the other area of the in-vehicle system except the status bar may be used for displaying the entire area of the interface, and the first display area and the second display area may occupy the other area except the status bar.

In one possible design, before the electronic device controls the in-vehicle system to display in a split screen manner, the electronic device adjusts the size of a first display interface of the first application, so that the adjusted size of the first display interface is adapted to the first display area; the electronic equipment adjusts a first layout of the first application so that the first layout is adaptive to the first display interface after the first layout is adjusted in size; and/or the electronic device adjusts the size of the second interface so that the adjusted size of the second interface is adapted to the second display area; and the electronic equipment adjusts the second layout of the second interface so that the second layout is matched with the second interface after the size adjustment.

For example, the electronic device is connected to the vehicle-mounted system, the electronic device displays a display interface of the map application, the electronic device projects a screen to the vehicle-mounted system, and the vehicle-mounted system displays the display interface of the map application. When the electronic equipment receives the operation of returning to the main interface, the map application is switched to the background, the foreground displays the main interface, and at the moment, the vehicle-mounted system can be controlled to display in a split screen mode, so that the vehicle-mounted system can simultaneously display the display interface and the main interface of the map application. The electronic device can adjust the layout and the window size of the map application to adapt to the size of the first display area on the vehicle-mounted system, and can also adjust the layout and the window size of the main interface to adapt to the size of the second display area of the vehicle-mounted system. In the scheme, even if the map application is switched to the background by the electronic equipment, the foreground of the vehicle-mounted system still displays the display interface of the map application, so that a user can conveniently check the map, and the driving safety is improved.

In a second aspect, the present application further provides an electronic device. The electronic device includes a communication module, one or more processors, one or more memories, a display screen, and an input device; the communication module is used for communicating with a vehicle-mounted system so as to project a screen to the vehicle-mounted system; an input device for receiving an input operation; the display screen is used for displaying a main interface and/or a display interface applied in the electronic equipment; one or more memories for storing program instructions for execution by the one or more processors to enable an electronic device to implement the first aspect as described above or any one of the possible design methods of the first aspect.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise. It should also be understood that in the embodiments of the present application, "one or more" means one, two, or more than two; "and/or" describes the association relationship of the associated objects, indicating that three relationships may exist; for example, a and/or B, may represent: a alone, both A and B, and B alone, where A, B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.

Hereinafter, some terms in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

An application (app for short) according to an embodiment of the present application is a software program capable of implementing one or more specific functions. Generally, a plurality of applications may be installed in an electronic device. Such as applications with navigation functions, instant messaging applications, etc. Wherein, the application with navigation function can include: baidu maps, Gade maps, etc. The instant messaging application may include: telephone, WeChat, Tencent chat software (QQ), WhatsApp Messenger, Lianme (Line), photo sharing (instagram), Kakao Talk, nailed, etc. The electronic device can realize a navigation function through a map application, and can realize voice, video call and the like with other electronic devices through a communication application. In some cases, navigation functionality may also be integrated into the instant messaging application, for example, including send location functionality in the WeChat application. For example, the electronic device a displays a display interface of a wechat application, the wechat application receives the location sent by the contact B, and the electronic device a may select different map software (e.g., a hundred-degree map) for navigation. It should be noted that, the following embodiments describe the technical solution of the present application by taking a map application as an example, and of course, if a navigation function is integrated in other applications (for example, a wechat application), the screen splitting scheme of the vehicle-mounted system provided in the embodiments of the present application may also be applied to other applications (for example, the wechat application). For example, the cellular phone 100 is connected to an in-vehicle system. The front of the mobile phone 100 displays a real-time location sharing interface in the WeChat application, and projects the interface to the vehicle-mounted system. If the mobile phone 100 switches the wechat application to the background, the foreground displays the main interface, and can control the vehicle-mounted system to display in a split screen manner, that is, the vehicle-mounted system simultaneously displays the main interface and the interface shared by the real-time positions of the wechat application. The application program mentioned in the embodiment of the present application may be an application program installed when the electronic device leaves a factory, or an application program downloaded from a network or acquired by another electronic device during a process of using the electronic device by a user.

The embodiments of the present application relate to at least one, including one or more; wherein a plurality means greater than or equal to two. In addition, it is to be understood that the terms first, second, etc. in the description of the present application are used for distinguishing between the descriptions and not necessarily for describing a sequential or chronological order.

The application is executed in the foreground, namely the application is running, a display interface of the application is displayed on a display screen, and the application is executed in the background, namely the application is running, but the display interface of the application is not displayed on the display screen. Taking a mobile phone as an example, a display screen of the mobile phone is displaying a display interface of a map application (a high-grade map, a Baidu map, and the like), and then, the map application runs in the foreground. If the mobile phone receives an incoming call in the process of displaying the display interface of the map application, the display screen displays the incoming call interface (including the incoming call number, the interface of controls for answering and hanging up) and does not display the display interface of the map application, at this moment, the map application is switched to the background operation, and the telephone application is operated in the foreground.

Fig. 1 shows a schematic diagram of a possible application scenario provided in an embodiment of the present application. As shown in fig. 1, a terminal device (in fig. 1, the terminal device is a mobile phone, for example) is connected to the in-vehicle system. The mobile phone can be projected to the vehicle-mounted system, namely the vehicle-mounted system displays the display interface of the mobile phone. In some embodiments of the present application, the mobile phone may use the screen projection technology provided in the embodiments of the present application to project a screen to the vehicle-mounted system, and the screen projection technology may implement split-screen display of the vehicle-mounted system, so that the display screen of the vehicle-mounted system may simultaneously display the display interfaces of at least two applications on the mobile phone, such as the display interfaces of a map application and other applications (e.g., a phone application, a WeChat application, etc.), so that a user may view a line through the map application while using other applications to process a transaction (e.g., answer an incoming call) during driving, which is helpful to improve driving safety. The screen projection process will be described later.

For example, the mobile phone may use heterogeneous screen projection technology to project a screen to the vehicle system.

The heterogeneous screen projection technology related to the embodiment of the application takes the screen projection from the first electronic device to the second electronic device as an example, and the heterogeneous screen projection, that is, the screen projection contents can be displayed asynchronously by the first electronic device and the second electronic device, or the display contents of the first electronic device and the second electronic device can be different. For example, taking fig. 1 as an example, after the mobile phone projects the display interface of the map application a to the vehicle-mounted system, the mobile phone may switch the map application a to the background operation, and the foreground of the mobile phone displays the display interface of the main interface or other applications B. In the process that the mobile phone displays the main interface or the display interface of other application B, one area displayed by the vehicle-mounted system in a split screen mode still displays the display interface of the map application A, namely, the mobile phone and the vehicle-mounted system display screen projection content asynchronously. The heterogeneous screen projection technology can realize that the mobile phone projects the first interface of the first application to the screens of other electronic devices, and the mobile phone displays the second interface of the second application, so that the operation of a user is facilitated.

In the following embodiments, the terminal device is a mobile phone as an example, and fig. 2 shows a schematic structural diagram of the mobile phone 100.

It is to be understood that the illustrated structure of the embodiment of the present application does not specifically limit the mobile phone 100. In other embodiments of the present application, the handset 100 may include more or fewer components than shown, or some components may be combined, some components may be separated, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

In some embodiments of the present application, the handset 100 may be connected to an in-vehicle system. After the mobile phone 100 is connected to the vehicle-mounted system, the screen can be projected to the vehicle-mounted system, so that the display screen of the vehicle-mounted system displays the display interface of the mobile phone. Under different scenes, the mobile phone 100 can control the in-vehicle system to display by using different display strategies.

Another possible scenario is that the handset 100 displays the display interface of other applications (e.g., phone applications) in the foreground, without running the map application. The mobile phone 100 can project the current display interface to the vehicle-mounted system, so that the vehicle-mounted system displays the display interface of the other application. The cellular phone 100 detects an input operation for starting a map application. The cellular phone 100 displays a display interface of the map application in response to the input operation. The mobile phone 100 controls the vehicle-mounted system to display the display interface of the map application in a full screen mode.

Yet another possible scenario is that the handset 100 runs a map application in the foreground. The mobile phone 100 is projected to the vehicle system, and the vehicle system displays a display interface of the map application. The cell phone 100 starts other applications (e.g., phone applications), switches the map application to run in the background, and displays the display interfaces of the other applications (e.g., phone applications) in the foreground. In this case, the mobile phone 100 may control the in-vehicle system to enter a split-screen mode, in which the display screen of the in-vehicle system simultaneously displays the display interface of the map application and the display interfaces of other applications. In this scenario, the map application in the mobile phone 100 runs in the background, and the split-screen display of the vehicle-mounted system can be controlled, i.e., the display interface of the map application displayed on the foreground of the vehicle-mounted system can still be ensured, so that the driver can view the map application, and the driving safety can be improved.

Yet another possible scenario is that the mobile phone 100 runs the map application in the background and displays the display interfaces of other applications in the foreground. The mobile phone 100 controls the on-board system to display in a split screen manner, that is, the on-board system display screen simultaneously displays the display interface of the map application and the display interfaces of other applications. When the map application is switched from the background to the foreground (for example, the other application is exited or the other application is switched to the background), the mobile phone 100 may control the in-vehicle system to exit the split-screen mode, that is, the in-vehicle system displays the display interface of the map application in a full screen mode. In this scenario, as long as the mobile phone 100 runs the map application in the foreground, the in-vehicle system displays the display interface of the map application in a full screen manner.

Therefore, in the embodiment of the present application, no matter the mobile phone 100 runs the map application at the current running or the background running, the display interface of the map application displayed on the foreground of the vehicle-mounted system can be ensured, so that the driver can conveniently view the map application, and the driving safety can be improved.

The following embodiments illustrate the different scenarios described above.

Example 1: the mobile phone 100 currently displays the main interface; or, displaying a black screen; or, a screen-locking interface is displayed, and after the mobile phone 100 starts an application (for example, a map application or other applications), the mobile phone 100 displays a display interface of the application. The mobile phone 100 is projected to the vehicle-mounted system, so that the display screen of the vehicle-mounted system displays the display interface of the application in a full screen mode.

For example, referring to fig. 4(a), the mobile phone 100 is connected to the in-vehicle system 400. The handset 100 displays a home interface 401. The mobile phone 100 is projected to the in-vehicle system, so that the in-vehicle system displays an interface with the same or similar content as the main interface 401. The interface with content similar to that of the main interface 401 may be, for example, an interface including an icon applied in the main interface 401, but not including a status bar (an area for displaying information such as battery level, signal strength, and operator identifier) in the main interface 401, or another interface, which is not limited in the embodiment of the present application. With continued reference to fig. 4(a), when the cellular phone 100 detects an operation for the icon 402 of the telephone application in the home interface 401, the cellular phone 100 displays a display interface of the telephone application as shown in fig. 4 (b). The mobile phone 100 may project the display interface of the phone application to the in-vehicle system 400 so that the in-vehicle system 400 displays the display interface of the phone application.

In the above embodiment, in the case where the mobile phone 100 does not run the map application, the in-vehicle system may not need the split screen display. The display interface of the mobile phone 100 and the display interface of the in-vehicle system may be the same, for example, the mobile phone 100 and the in-vehicle system display the display interface of the same application.

Example 2: the cell phone 100 switches the map application from foreground to background running.

In some embodiments, the cell phone 100 runs the map application in the foreground, e.g., the cell phone 100 displays the display interface of the map application full screen. The mobile phone 100 starts other applications, switches the map application to the background operation, and operates the other applications in the foreground. The mobile phone 100 may control the vehicle-mounted system to enter a split-screen mode, where a first display area on a display screen of the vehicle-mounted system displays a display interface of a map application, and a second display area displays display interfaces of other applications. It should be noted that, when the in-vehicle system enters the split screen mode, the display areas of the first display area and the second display area may be the same or different, and the embodiment of the present application is not limited. In some embodiments, the display positions, the display areas, and the like of the first display area and the second display area may be set by default after the vehicle-mounted system leaves the factory, or may be set by a user. For example, the display screen of the in-vehicle system is a touch screen, and the display areas of the first display area and the second display area can be enlarged or reduced or the display position can be changed under the action of touch operation of a user.

For example, when the display screen of the in-vehicle system is a touch screen, the touch screen may also detect an input operation. Taking fig. 5a (b) as an example, the in-vehicle system displays in a split screen manner, the first display area (left display area) displays a display interface of the telephone application, and the second display area (right display area) displays a display interface of the map application. When the touch screen of the vehicle-mounted system detects the preset operation, the split screen can be quitted, and the display interface of the map application is displayed in a full screen mode. The preset operation may be a single click/double click operation at any position in the right display area, or an operation for a certain function control (the function control is used to exit the split screen mode) on the vehicle-mounted system, or an operation for reducing the display area of the left display area, or an operation for enlarging the display area of the right display area, and the like, and the embodiment of the present application is not limited.

As another example, the display of the cell phone 100 displays a display interface of a map application. The mobile phone 100 controls the in-vehicle system to display a display interface of the map application. When the mobile phone 100 detects an input operation, for example, the input operation may be an operation for a home key, and in response to the input operation, the map application is switched to a background running mode, and the foreground displays a main interface. The mobile phone 100 may control the vehicle-mounted system to enter a split-screen mode, where a first display area on a display screen of the vehicle-mounted system displays a display interface of a map application, and a second display area displays a main interface.

As another example, the display of the cell phone 100 displays a display interface of a map application. The mobile phone 100 controls the in-vehicle system to display a display interface of the map application. The handset 100 receives a new message (e.g., of a WeChat application) that is displayed in a status bar (an area that displays battery level, signal strength, operator identification, etc.). The mobile phone 100 detects an input operation, for example, the input operation may be an operation for a new message in the status bar, and in response to the input operation, the map application is switched to a background running mode, and a display interface of the WeChat application is displayed in a foreground, where the new message may be included in the display interface. The mobile phone 100 may control the vehicle-mounted system to enter a split-screen mode, where a first display area on a display screen of the vehicle-mounted system displays a display interface of a map application, and a second display area displays a display interface of a WeChat application.

In the above example, when the map application in the mobile phone 100 runs in the background, the in-vehicle system can be controlled to display in a split screen manner, so that the display interface of the in-vehicle system foreground displaying the map application can still be ensured, so that the driver can view the map application, and the driving safety can be improved.

Example 3: the mobile phone 100 switches the map application from the background to the foreground running.

For example, referring to fig. 6(a), the mobile phone 100 runs a map application in the background and displays the main interface in the foreground. The vehicle-mounted system 600 displays in a split screen manner, the display interface of the map application is displayed in the right display area, and the main interface is displayed in the left display area. When the mobile phone 100 detects an operation of the icon 601 for the map application in the main interface, the map application is switched to be operated from the background to the foreground. The mobile phone 100 controls the in-vehicle system to exit the split-screen mode, so that the in-vehicle system displays the display interface of the map application in a full screen mode, as shown in fig. 6 (b).

As described above, the map application may have a navigation function, and the navigation function may be a walking route planned by the map application according to a departure place (e.g., a current position) and a destination, and after the map application starts the navigation function, the current geographic position may be located in real time (e.g., the current position is located in real time by GPS) until the destination is reached. In some cases, after the mobile phone 100 starts the map application, the navigation function of the map application may not be opened temporarily, and in the case that the navigation function is not opened, if the mobile phone 100 switches the map application to the background and the foreground displays other interfaces, the mobile phone 100 may control the vehicle-mounted system to display the other interfaces in a full screen manner, that is, it is not necessary to control the vehicle-mounted system to display in a split screen manner. Certainly, in other embodiments, after the mobile phone 100 starts the map application, even if the map application temporarily does not turn on the navigation function, if the map application is switched to the background, the mobile phone 100 may control the on-vehicle system to display in a split screen manner, so that a display interface of the map application is displayed in an area after the on-vehicle system is split screen.

In other cases, the mobile phone 100 can only control the vehicle-mounted system by using the technical scheme described in the above embodiment after starting the map application and starting the navigation function in the map application, that is, in this case, only when the mobile phone 100 starts the map application and opens the navigation function of the map application, if the map application is switched to the background, the vehicle-mounted system is controlled to display in a split screen manner, so that a display interface of the map application is displayed in an area after the vehicle-mounted split screen.

As an example, taking a high-end map as an example, the mobile phone 100 starts a high-end application, but does not open a navigation function in the high-end application, so that a display interface of the high-end map is displayed in the foreground, and the display interface does not include any route navigation (possibly, the map application is opened by false triggering). At this time, if the mobile phone 100 switches the height map (without opening the navigation function) from the foreground to the background, the foreground displays the main interface, and the mobile phone 100 may not need to control the vehicle-mounted system to enter the split-screen mode, that is, the vehicle-mounted system may display the display interface of the other application in a full screen. Of course, if the mobile phone 100 switches the high-level map to the background and the foreground displays the main interface when the navigation function of the high-level map is not turned on (the display interface does not display the route navigation), the mobile phone 100 may also control the vehicle-mounted system to display in a split screen manner. As another example, when the mobile phone 100 displays a display interface of a high-grade map in the foreground, and the display interface includes route navigation (turning on a navigation function), if the mobile phone 100 switches the high-grade map to the background, the foreground displays a main interface, and the mobile phone 100 controls the vehicle-mounted system to display in a split screen manner.

In some embodiments, after the mobile phone 100 opens the navigation function in the map application, the foreground may display a display interface of the map application, which may include a map and a navigation card. For example, refer to fig. 7, which is a schematic diagram of a display interface of a map application. As shown in fig. 7, after the mobile phone 100 starts the map application and starts the navigation function, the mobile phone 100 displays a display interface of the map application, where the display interface includes a map and a navigation card. The navigation card may display navigation information, such as a distance between a current location and a destination, driving direction information (e.g., an arrow), time information, and the like. In some embodiments, the map may be displayed on a lower level and the navigation card may be displayed on an upper level of the map.

As an example, after the mobile phone 100 opens the navigation function in the map application, the foreground may display a first display interface of the map application, where the first display interface may include a map and a navigation card. The mobile phone 100 switches the map application to the background operation, and the foreground displays the second display interfaces of other applications. The mobile phone 100 can control the vehicle-mounted system to enter a split-screen mode, so that the vehicle-mounted system simultaneously displays a second display interface of other applications and a first display interface of a map application, wherein the first display interface comprises a map and a navigation card; or the vehicle-mounted system can simultaneously display the second display interfaces of other applications and the navigation card in the map application without displaying the map. As another example, the mobile phone 100 starts a map application, but does not open a navigation function in the map application, so a first display interface of the map application is displayed in the foreground, and the first display interface only includes a map and does not include a navigation card. The mobile phone 100 switches the map application to the background operation, and the foreground displays the second display interfaces of other applications. At this time, the mobile phone 100 may control the in-vehicle system to perform split-screen display, so that the first display area of the in-vehicle system displays the second display interface of another application, and the second display area displays the first display interface of the map application, where the first display interface includes a map and does not include a navigation card.

For example, referring to fig. 8(a), the mobile phone 100 is connected to an in-vehicle system 800. A display interface of a map application (e.g., a gold application) is displayed on a display screen of the cell phone 100, and includes a map and a navigation card. The mobile phone 100 is projected to the vehicle-mounted system 800, and the vehicle-mounted system 800 displays a display interface of a map application, wherein the display interface comprises a map and a navigation card. Referring to fig. 8(b), the mobile phone 100 receives an incoming call, switches the map application to the background running, and displays the display interface of the phone application in the foreground. The mobile phone 100 may control the in-vehicle system 800 to enter the split-screen mode. In the split screen mode, a display interface of the telephone application is displayed in a left display area on a display screen of the vehicle-mounted system, and a navigation card of the map application is displayed in a right display area without displaying a map; or the display screen of the vehicle-mounted system displays the display interface of the telephone application in the left display area, and displays the map in the map application in the right display area without displaying the navigation card; or the display interface of the telephone application is displayed in the right display area on the display screen of the vehicle-mounted system, and the navigation card of the map application is displayed in the left display area, but the map is not displayed; or the display screen of the vehicle-mounted system displays the display interface of the telephone application in the right display area, and displays the map in the map application in the left display area without displaying the navigation card. In other examples, the in-vehicle system may display the display interface of the phone application full screen, display the navigation card on an upper layer of the display interface, and not display the map; or the vehicle-mounted system may display the map and/or the navigation card in the map application in a full screen mode, and display the display interface of the phone application on the upper layer, which is not limited in the embodiment of the present application.

In the embodiment of the application, although the mobile phone 100 runs the map application in the background, the display screen of the vehicle-mounted system can be controlled to display the display interface of the map application in the foreground, and the display screen of the vehicle-mounted system can be displayed in a split screen mode, for example, the display interfaces of the map application and other applications are displayed simultaneously. In this way, the driver can still see the map application display interface map and/or navigation card while using other applications to handle transactions, which is helpful to improve driving safety.

In some embodiments, the display screens of different in-vehicle systems are different. For example, the display screen of the vehicle-mounted system can be a horizontal screen or a vertical screen. The split screen mode of the vehicle-mounted system can be different under the horizontal screen and the vertical screen. Referring to fig. 9(a), the display screen of the in-vehicle system is a landscape screen, and the display screen includes an app area. When the in-vehicle system is displayed in a split screen mode, the app area can be divided into two display areas, for example, an area A and an area B. The display areas of the two regions may be the same or different. For example, the ratio between the first length of the a region and the second length of the B region may be a preset ratio, and the preset ratio may be, for example, 3: 1 or 4: 1, etc. The area a and the area B may display interfaces of different applications. Specifically, the area a and the area B are respectively used for displaying a display interface of which application, and the embodiment of the present application is not limited. Referring to fig. 9(b), the display screen of the in-vehicle system is a vertical screen, and the display screen includes an app area. When the in-vehicle system is displayed in a split screen mode, the app area can be divided into two display areas, such as an area A and an area B. The display areas of the two display regions may be the same or different. For example, the ratio between the first width of the a region and the second width of the B region may be a threshold ratio, and the preset ratio may be 3: 1 or 4: 1, etc. The area a and the area B may display interfaces of different applications. Specifically, the area a and the area B are respectively used for displaying a display interface of which application, and the embodiment of the present application is not limited.

In some embodiments, after the mobile phone 100 is connected to the in-vehicle system, the display parameters of the in-vehicle system may be obtained, and the display parameters may include the size of the display screen of the in-vehicle system, such as the length and/or width of the display screen. The mobile phone 100 may adjust the display interface of the application according to the display parameters of the in-vehicle system. Taking fig. 9(a) as an example, after the mobile phone 100 controls the in-vehicle system to enter the split-screen mode, the mobile phone 100 may adjust the display interface of the first application, for example, adjust the layout of the first application according to the display area of the area a. The mobile phone 100 may further adjust the display interface of the second application, such as adjusting the layout of the second application, according to the display area of the B region. The layout of the first application may be a distribution manner of display contents (such as information of pictures, icons, and characters) in the first application. The layout of the second application may be a distribution of display content (such as information of pictures, icons, characters, etc.) in the second application.

The following embodiments describe software structures of an electronic device, which may be applied to the mobile phone 100 shown in fig. 2 or a similar electronic device, such as a tablet computer. The following embodiments take the example of the software structure applied to the mobile phone 100. In some embodiments, the software system of the handset 100 may employ a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present invention uses an Android system with a layered architecture as an example to exemplarily illustrate a software structure of the mobile phone 100. Fig. 10 shows a block diagram of a software structure of the mobile phone 100 according to an embodiment of the present invention. The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, for example, the Android system is divided into four layers, which are an application layer, an application framework layer, a system layer, and a kernel layer from top to bottom.

The application layer may include a series of application packages. As shown in fig. 10, the application packages may include camera, gallery, calendar, call, map, navigation, music, video, etc. applications.

The application framework layer may provide an Application Programming Interface (API) and a programming framework for an application of the application layer. The application framework layer may include some predefined functions. As shown in fig. 10, the application framework layer may include a vehicle management (my car manager). The vehicle-mounted management module can comprise an application state monitoring module, a logic judgment module, a navigation state monitoring module and a split screen state notification module. The mobile phone 100 can implement a screen projection process to the in-vehicle system through in-vehicle management in the application framework layer. Of course, the application framework layer may further include other modules, such as a window manager, a content provider, a view system, and the like, which are not described in detail in this embodiment of the present application.

In some embodiments, an application state monitoring module in the vehicle management may be configured to monitor the state of the application in the application layer. The state of the application may include application launch, exit, switch from foreground to background, or switch from background to foreground, etc. The navigation state monitoring module is used for monitoring whether a navigation function in the map application in the application program layer is started or not. The logic judgment module can be used for judging whether the split screen mode needs to be entered. In some embodiments, when the navigation state monitoring module monitors that the application program layer starts the navigation function, the logic judgment module determines that the vehicle-mounted system enters the split screen mode. For another example, when the navigation state monitoring module monitors that the application program layer closes the navigation function, the logic judgment module determines that the vehicle-mounted system exits the split screen mode. In other embodiments, when the application state monitoring module monitors that the map application in the application program layer is started, the logic judgment module determines that the vehicle-mounted system enters the split screen mode. And when the application state monitoring module monitors that the map application in the application program layer exits, the logic judgment module determines that the vehicle-mounted system exits the split screen mode. The split screen state notification module in the vehicle-mounted management can be used for notifying the application program layer vehicle-mounted system to enter or exit the split screen mode. The window adjusting module in the vehicle-mounted management can be used for adjusting display interfaces of different applications and the like.

And the system layer can comprise an Android runtime (Android runtime) and a system library. The Android Runtime can comprise a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system. The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android. The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like. The system library may include a plurality of functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), and the like. The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications. The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The core layer may include a display driver, a camera driver, an audio driver, a sensor driver, and the like.

Fig. 2 is a hardware configuration of the mobile phone 100 according to the embodiment of the present application, and fig. 10 is a software configuration of the mobile phone 100 according to the embodiment of the present application. Software programs and/or modules corresponding to the software structure shown in fig. 10 may be stored in the internal memory 121, and the processor 110 (e.g., the NPU or the CPU) executes the software programs and/or modules stored in the internal memory 121 to perform a process of projecting a screen to the in-vehicle system.

It should be understood that the size of the display screen of the vehicle-mounted system and the size of the display screen of the electronic device are not necessarily the same, and in order to adapt the size of the display screen of the vehicle-mounted system, the vehicle-mounted management may call a resize function of the TaskRecord to adjust the size and layout of the window of the map application to adapt to the vehicle-mounted system before screen projection. For example, typically the size of the display screen of the in-vehicle system is large, and in-vehicle management may call the resize function of TaskRecord to increase the size of the window of the mapping application. One possible implementation is that the in-vehicle management sends the display parameters of the in-vehicle system, such as the size (length and width) of the app area shown in fig. 9(a), to the map application (after the cell phone 100 is connected to the in-vehicle system, the display parameters of the in-vehicle system may be acquired). The map application adjusts a size of a window of the application and a layout in the window based on the display parameters. The layout of the window may include a layout of buttons, icons, displayed text, etc. within the window. Therefore, the vehicle-mounted management can project the display interface of the adjusted map application to the vehicle-mounted system.

(4) And the telephone in the application program layer receives the incoming call. An application state monitoring module in the vehicle-mounted management monitors the incoming call of the telephone, and the high-grade map is switched to the background to run. And the logic judgment module determines that the vehicle-mounted system enters a split screen mode according to the application state monitored by the application state module. The split screen state notification module broadcasts a broadcast message of "entering split screen" to notify an application (e.g., a map application) in an upper layer, i.e., an application layer, to adjust the layout of the application window.

It should be understood that, before (4), the in-vehicle system displays the display interface of the map application in a full screen mode, and after the phone in the application program layer receives an incoming call, the display interface of the map application on the in-vehicle system needs to be reduced to make the display area display the incoming call interface of the phone application. Therefore, the map application needs to adjust the layout of the display interface to fit the reduced size (activity of the map application has been set to Freeform window mode). One possible implementation manner is that the application framework layer reports the display parameters of the vehicle-mounted system to the map application, and the display parameters may be the size (length and width) of the area a in fig. 9 (a). The map application adjusts the window layout based on the display parameter.

In some embodiments, the phone application in the application layer may also adjust the window layout. For example, the application framework layer reports the display parameters of the vehicle-mounted system to the phone application, and the display parameters may be the size (length and width) of the B area in fig. 9 (a). The phone application adjusts the window layout and size based on the display parameters.

In some embodiments, the activity of a portion of the applications in the application layer is to support a resizable function, i.e., a function to adjust window layout and size, then the portion of the applications may adjust window layout and size themselves. The activity of other applications does not support the resizable function, and for the applications which do not support the resizable function, the application framework layer can force the window layout and size of the application to be adjusted, so that the adjustment workload of the application can be reduced. For example, the application framework layer may implement forced adjustment of the window layout of the application by a pile driving TaskRecord, where the pile driving TaskRecord means that parameters of a resize function in the TaskRecord are forcibly modified to achieve the purpose of adjusting the layout and size of the window.

(5) And after the map application in the application framework layer adjusts the layout, informing the application program of the layout in the application framework layer. And a window adjusting module in the application program framework layer synthesizes a display interface based on the layout after map application adjustment and the layout after telephone application adjustment, and sends the display interface to the vehicle-mounted system, so that the vehicle-mounted system displays the display interface of the map application and the incoming call interface of the telephone in a split screen mode.

As can be seen from the above embodiments, the mobile phone 100 switches the map application from the foreground to the background. But the display interface of the map application is still displayed on the front desk of the vehicle-mounted system, and the display screen of the vehicle-mounted system is displayed in a split screen mode, and meanwhile the display interfaces of the map application and other applications are displayed. Therefore, the driver can still see the display interface of the map application while using other applications to process transactions, and driving safety is improved.

The following embodiment describes a process of the mobile phone 100 controlling the in-vehicle system to exit from the split-screen mode to the split-screen mode.

(1) And ending the call answering by the telephone. An application state monitoring module in vehicle-mounted management monitors that the telephone application is switched to background operation and the Gade map is switched to foreground operation from the background. And a logic judgment module in the vehicle-mounted management determines that the vehicle-mounted system exits the split screen mode. The split screen state notification module broadcasts a broadcast message of 'quitting split screen'. The layout is adjusted again after the broadcast information is received by the hadamard application in the application layer. One possible implementation is that the onboard management reports display parameters of the high-end map onboard system, which may be the size (length and width) of the app area in fig. 9 (a). The map application resizes the layout based on the display parameter.

(2) And the window adjusting module in the vehicle-mounted management determines the display interface of the God application based on the adjusted layout of the God map. The vehicle-mounted management controls the communication module in the mobile phone 100 to project a screen to the vehicle-mounted system through the kernel layer, so that the vehicle-mounted system displays a display interface of the Gade map on the whole screen.

In other embodiments, the application layer may broadcast an "end navigation" message when navigation in the application layer exits or the map application in the application layer turns off the navigation function. After the application framework layer receives the broadcast information, the Freeform window mode of the grand map may be exited.

The various embodiments of the present application can be combined arbitrarily to achieve different technical effects.

With reference to the foregoing embodiments and the related drawings, embodiments of the present application provide a split-screen display method for a vehicle-mounted system, where the method may be implemented in an electronic device (e.g., a mobile phone, a tablet computer, etc.). For example, the electronic device may be configured as shown in fig. 2, and the electronic device is connected to an in-vehicle system, and the in-vehicle system may have a display screen. As shown in fig. 11, the flow of the method may include the following steps:

and 1101, displaying a first interface by the electronic equipment, wherein the first interface comprises a first display interface of a first application, and the first application has a navigation function.

For example, the first application may be a mapping application, such as a grand map, a Baidu map, etc., and the first display interface of the first application may include a map and/or navigation information, etc.

And 1102, controlling the vehicle-mounted system to display a first display interface of the first application by the electronic equipment.

For example, taking fig. 5a (a) as an example, the mobile phone displays a display interface of a map application, where the display interface includes a map. And the mobile phone projects the display interface of the map application to the vehicle-mounted system so that the vehicle-mounted system displays the display interface of the map application. For example, the electronic device controls the in-vehicle system to display the first display interface, which may be that the electronic device sends the first display interface to the in-vehicle system (for example, sends the first display interface to the in-vehicle system in the form of a picture), so that the in-vehicle system sends the first display interface; alternatively, the electronic device may send a drawing element (or may also be referred to as an image element) included in the first display interface to the in-vehicle system, and the in-vehicle system may obtain the first display interface according to the drawing element, where the drawing element may include an element in the first display interface (e.g., a button, an icon, text, a picture, and the like in the first display interface), and a size, a position, and the like of the element.

1103, the electronic device detects a first input operation.

For example, taking fig. 5b (a) as an example, the first input operation may be an operation on a listening control, or the first input operation may be an operation on returning to the main interface, or after receiving a new message, the electronic device displays the message in the first interface, and the first input operation may also be an operation on a message in a status bar (the operation is used to open a second display interface of a second application corresponding to the message).

And 1104, the electronic device responds to the first input operation, switches the first application to a background running state, and displays a second interface.

For example, taking fig. 5b (a) as an example, the first input operation is an operation for an answering control, the electronic device switches the first application to a background, and a foreground displays a call interface. The first input operation can also be an operation of returning to the main interface, the electronic equipment detects the first input operation, switches the first application to the background operation, and the foreground displays the second interface, namely the main interface. After receiving the new message, the electronic device displays the message in a first interface (for example, a status bar in the first interface), the first input operation may also be an operation for the message, and the electronic device opens a second display interface of a second application corresponding to the message corresponding to the operation, and switches the first application to a background operation.

1105, the electronic device controls the on-vehicle system to display in a split screen manner, so that a first display area on the display screen of the on-vehicle system displays a first display interface of the first application, and a second display area on the display screen displays the second interface.

For example, the electronic device may control the in-vehicle system to perform split-screen display, where the electronic device sends the first display interface and the second interface to the in-vehicle system together (for example, sends the first display interface and the second interface to the in-vehicle system in the form of pictures respectively, or sends the first display interface and the second interface to the in-vehicle system after synthesizing one picture), so that the in-vehicle system simultaneously displays the first display interface and the second interface. Or the electronic device may send a first drawing element included in the first display interface to the vehicle-mounted system, and send a second drawing element of the second interface to the vehicle-mounted system, and the vehicle-mounted system may obtain the first display interface according to the first drawing element, where the first drawing element may include an element (e.g., a button, an icon, text, a picture, etc. in the first display interface) in the first display interface, and a size, a position, etc. of the element; the second interface may be derived from a second rendered element that includes elements in the second interface (e.g., buttons, icons, text, pictures, etc. in the second interface), as well as the size, location, etc. of the elements.
