技术领域technical field
本发明涉及一种行车辅助装置，特别涉及一种行车导航装置。The invention relates to a driving assistance device, in particular to a driving navigation device.
背景技术Background technique
随着科技的进步，电子产品的应用也越来越普遍，如智能型手机(Smart phone)、个人数字助理(Personal Digital Assistant)、导航装置及平板电脑等等，俨然已成为大众化的电子产品。在开车过程中，驾驶人可利用电子产品随时定位目前的位置并规划导航路径，以协助与提示驾驶人前往目的地，使行车能更加顺畅与便利。With the advancement of technology, the application of electronic products has become more and more common, such as smart phones (Smart phones), personal digital assistants (Personal Digital Assistant), navigation devices and tablet computers, etc., which have become popular electronic products. During the driving process, the driver can use electronic products to locate the current position and plan the navigation path at any time, so as to assist and prompt the driver to go to the destination, making the driving smoother and more convenient.
然而，目前电子产品的导航方式都是在显示屏幕上显示二维平面电子地图与导航路径，然而，电子地图通常仅有显示基本的图资，例如道路名称或主要建筑物名称，且与驾驶人实际看到的前方或周遭景像并不相同，因此驾驶人须仔细比对电子地图与所看到的周遭景象才能知道确切的位置，造成无法快速且直觉地辨别而增加行车的危险性。However, the current navigation methods of electronic products are to display a two-dimensional plane electronic map and navigation route on the display screen. However, the electronic map usually only displays basic graphics, such as road names or main building names, and is related to the driver. The actual scene ahead or the surrounding scene is not the same, so the driver must carefully compare the electronic map with the surrounding scene he sees to know the exact location, resulting in the inability to quickly and intuitively identify and increase the danger of driving.

显示模块50具体上为设置于车辆2内部(如仪表板上)并连接于处理模块40与导航模块20的一显示屏幕，或者显示模块50也可为抬头显示器或智能型电子产品(如智能型手机或平板电脑)的显示屏幕，此部分并不局限。显示模块50选择性地显示二维导航地图21、三维导航地图24或三维环场导航影像INA。换言之，显示模块50可在二维导航地图21、三维导航地图24及三维环场导航影像INA三者之间切换显示。The display module 50 is specifically a display screen disposed inside the vehicle 2 (such as a dashboard) and connected to the processing module 40 and the navigation module 20, or the display module 50 can also be a head-up display or an intelligent electronic product (such as an intelligent electronic product). The display screen of the mobile phone or tablet), this part is not limited. The display module 50 selectively displays the two-dimensional navigation map 21 , the three-dimensional navigation map 24 or the three-dimensional surrounding field navigation image I NA . In other words, the display module 50 can switch the display among the two-dimensional navigation map 21 , the three-dimensional navigation map 24 and the three-dimensional surrounding navigation image INA .
藉此，驾驶人在行车导航过程中可视需求切换显示三维环场导航影像INA，而能观看车辆2实际的周遭环境与周遭设施的设施信息，使驾驶人能快速且直觉地辨识周遭设施的位置及信息，且更精确地得知导航信息的指示。In this way, the driver can switch the display of the three-dimensional surrounding field navigation image I NA as required during the driving navigation process, and can view the actual surrounding environment of the vehicle 2 and the facility information of the surrounding facilities, so that the driver can quickly and intuitively identify the surrounding facilities. location and information, and more accurate indication of navigation information.

The display module 50 directly switches and displays the three-dimensional navigation image I NA from the two-dimensional navigation map 21 in response to the third switching signal. That is to say, the display module 50 can directly switch and display the three-dimensional navigation image I NA from the 2D navigation map 21 according to the third switching signal, or the display module 50 can switch and display the 2D navigation map 21 first according to the first switching signal. The three-dimensional navigation map 24 is then switched to display the three-dimensional navigation image I NA from the three-dimensional navigation map 24 according to the second switching signal.
上述第一切换信号、第二切换信号及第三切换信号可通过手动或自动输入产生，此分别说明如下。举例来说，如图4所示，显示模块50可包括有一触控界面51，触控界面51可检测驾驶人的手势输入(如通过手指在触控界面51上滑移)而输出第一触控轨迹52、第二触控轨迹53或第三触控轨迹54，处理模块40接收并分别对应第一触控轨迹52、第二触控轨迹53或第三触控轨迹54输出上述的第一切换信号、第二切换信号或第三切换信号。The above-mentioned first switching signal, second switching signal and third switching signal can be generated by manual or automatic input, which are respectively described below. For example, as shown in FIG. 4 , the display module 50 can include a touch interface 51 , and the touch interface 51 can detect the driver's gesture input (eg, by sliding a finger on the touch interface 51 ) and output the first touch The control track 52 , the second touch track 53 or the third touch track 54 , the processing module 40 receives and outputs the first touch track 52 , the second touch track 53 or the third touch track 54 respectively corresponding to the first touch track 52 , the second touch track 53 or the third touch track 54 . A switching signal, a second switching signal, or a third switching signal.
于一实施例中，第一触控轨迹52是与第二触控轨迹53相同，第三触控轨迹54与第一触控轨迹52的轨迹不同。举例来说，请参阅图10所示，驾驶人可通过两指相对滑移(如图中箭号指示的方向)而产生第一触控轨迹52与第二触控轨迹53，在一些实施例中，驾驶人通过两指相对滑移时，可使导航地图产生缩放效果，当导航地图放大到一预定程度时才产生上述第一切换信号与第二切换信号。或者，请参阅图11所示，驾驶人可通过三指横向滑移(如图中箭号指示的方向)而产生第一触控轨迹52与第二触控轨迹53。再请参图12所示，驾驶人可通过五指由内向外滑移(如图中箭号指示的方向)而产生第三触控轨迹54。In one embodiment, the first touch track 52 is the same as the second touch track 53 , and the third touch track 54 is different from the first touch track 52 . For example, as shown in FIG. 10 , the driver can generate the first touch track 52 and the second touch track 53 by sliding two fingers relative to each other (in the direction indicated by the arrow in the figure), in some embodiments. Among them, when the driver slides two fingers relative to each other, the navigation map can be zoomed, and the first switching signal and the second switching signal are generated only when the navigation map is enlarged to a predetermined level. Alternatively, as shown in FIG. 11 , the driver can generate the first touch track 52 and the second touch track 53 by sliding three fingers laterally (in the direction indicated by the arrow in the figure). Referring to FIG. 12 again, the driver can generate the third touch track 54 by sliding his five fingers from the inside to the outside (in the direction indicated by the arrow in the figure).
于一实施例中，显示模块50包括有触控界面51，触控界面51显示多个触控选项55，处理模块40对应的各触控选项55的选取输出第一切换信号、第二切换信号或第三切换信号。如图8所示，在本实施例中，触控界面51是显示2D、3D及AVM的触控选项55，驾驶人可触压2D的触控选项55使显示模块50显示二维导航地图21，而触压AVM的触控选项55使显示模块50切换显示三维环场导航影像INA。In one embodiment, the display module 50 includes a touch interface 51 , the touch interface 51 displays a plurality of touch options 55 , and the selection of each touch option 55 corresponding to the processing module 40 outputs a first switching signal and a second switching signal. or the third switching signal. As shown in FIG. 8 , in this embodiment, the touch interface 51 displays 2D, 3D and AVM touch options 55 , and the driver can touch the 2D touch option 55 to make the display module 50 display the 2D navigation map 21 , and pressing the touch option 55 of the AVM causes the display module 50 to switch and display the three-dimensional surround-field navigation image I NA .
于一实施例中，处理模块40更比对车辆即时位置与目的地位置而输出行车距离，并比对行车距离与预设距离自动输出第一切换信号、第二切换信号或第三切换信号。详言之，假设预设距离分别设定为50米与200米，当行车距离大于200米时，显示模块50是显示二维导航地图21，当行车距离介于50米到200米之间时，处理模块40输出第一切换信号使显示模块50显示三维导航地图24，当行车距离小于50米时，处理模块40输出第二切换信号使显示模块50显示三维环场导航影像INA。也就是说，行车导航装置1越接近目的地可自动显示越精细的导航影像。在一些实施例中，上述预设距离亦可依使用者喜好自行设定，此部分并不局限。In one embodiment, the processing module 40 further compares the current position of the vehicle with the destination position to output the driving distance, and automatically outputs the first switching signal, the second switching signal or the third switching signal by comparing the driving distance and the preset distance. To be more specific, assuming that the preset distances are respectively set as 50 meters and 200 meters, when the driving distance is greater than 200 meters, the display module 50 displays the two-dimensional navigation map 21 , when the driving distance is between 50 meters and 200 meters. , the processing module 40 outputs the first switching signal to enable the display module 50 to display the 3D navigation map 24 , and when the driving distance is less than 50 meters, the processing module 40 outputs the second switching signal to enable the display module 50 to display the 3D navigation image I NA . That is, the driving navigation device 1 can automatically display a finer navigation image as it gets closer to the destination. In some embodiments, the above-mentioned preset distance can also be set according to the user's preference, but this part is not limited.
于一些实施例中，处理模块40也可依据其他预设条件自动控制显示模块50切换显示二维导航地图21、三维导航地图24或三维环场导航影像INA。举例来说，处理模块40可预设在驾驶人踩煞车减速时，控制显示模块50由二维导航地图21切换显示三维环场导航影像INA。或者，处理模块40是在车辆2行驶于窄巷中时，控制显示模块50由二维导航地图21切换显示三维环场导航影像INA。换言之，处理模块40可依据驾驶行为、行驶环境或其他喜好设定自动控制显示模块50切换显示二维导航地图21、三维导航地图24或三维环场导航影像INA，此部分并不局限。In some embodiments, the processing module 40 may also automatically control the display module 50 to switch and display the 2D navigation map 21 , the 3D navigation map 24 or the 3D surround navigation image I NA according to other preset conditions. For example, the processing module 40 may preset the control display module 50 to switch from the two-dimensional navigation map 21 to display the three-dimensional surrounding navigation image I NA when the driver decelerates by braking. Alternatively, the processing module 40 controls the display module 50 to switch from the two-dimensional navigation map 21 to display the three-dimensional surrounding navigation image I NA when the vehicle 2 is driving in a narrow alley. In other words, the processing module 40 can automatically control the display module 50 to switch and display the 2D navigation map 21 , the 3D navigation map 24 or the 3D navigation image I NA according to driving behavior, driving environment or other preferences, which is not limited.
