[0082] The present application provides a driving assistance method. The driving assistance method of an embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0083] Reference Figure 4 , Figure 4 A schematic diagram of a driving assistance method provided in an embodiment of the present application, the method may include:

[0084] Step S401: upon receiving a first voice instruction, determining a driving mode represented by the first voice instruction.

[0085] In a specific implementation, a voice module may be provided for the user to input a first voice command. When the first voice command input by the user is received, the driving mode represented by the first voice command may be obtained by analysis in this step.

[0086] Optionally, the voice module may be a voice button on the vehicle, or a voice sensing device on the vehicle.

[0087] Optionally, the voice module may provide a voice input interface for the user, and the voice input interface may be located on a display screen in the vehicle, and the user may initiate a first voice command by clicking a virtual button on the voice input interface.

[0088] Of course, the voice module can also be other, and this application does not specifically limit it.

[0089] Optionally, the driving mode is any of the following modes: normal driving mode, driving recorder mode, reversing mode, blind spot monitoring mode and panoramic parking mode. Of course, the driving mode in the embodiment of the present application can also be other, which is not limited in the present application.

[0090] The above-mentioned first voice command needs to include information that can represent the driving mode, such as the name of the driving mode, implicit information, etc. For example, if the driving mode is the reverse mode, the first voice command can be "turn on the reverse mode", or "please display the video data behind the vehicle", or "turn on the rearview camera", etc.

[0091] Step S402: Collecting the vehicle exterior video data through the auxiliary camera corresponding to the driving mode, wherein the auxiliary cameras corresponding to different driving modes are used to collect the vehicle exterior video data at different angles.

[0092] In this embodiment, a corresponding auxiliary camera may be assigned to each driving mode, so that the corresponding auxiliary camera can collect the external video data of the corresponding angle.

[0093] For example, the auxiliary cameras corresponding to the normal driving mode include the left rear-view camera and the right rear-view camera, so as to respectively collect the outside video data of the left rear side angle of the vehicle and the outside video data of the right rear side angle of the vehicle; the auxiliary cameras corresponding to the driving recorder mode include the front-view camera, so as to collect the outside video data of the front angle of the vehicle; the auxiliary cameras corresponding to the reversing mode include the rear-view camera, so as to collect the outside video data of the rear angle of the vehicle; the auxiliary cameras corresponding to the blind spot monitoring mode include the left rear-view camera, the left front-view camera, the right rear-view camera and the right front-view camera, so as to respectively collect the outside video data of the left rear side, left front side, right rear side and right front side angles of the vehicle; the auxiliary cameras corresponding to the panoramic parking mode include the surround-view camera, so as to collect the outside video data of the vehicle at a 360° angle.

[0094] Optionally, the left rear view camera and the right rear view camera can both be electronic exterior mirror cameras CMS (Camera Monitor System). Optionally, the left rear view camera and the right rear view camera are respectively installed on the left and right A-pillars on the outside of the vehicle, and are connected to the controller through a coaxial cable harness so that the controller can control the left rear view camera and the right rear view camera.

[0095] For example, see Figure 5 As shown in FIG. 1 , it is a schematic diagram of the installation positions of the left rear-view camera, the right rear-view camera and the target display screen provided in this application. Figure 5 The target display screen 600 is installed in front of the driver, the left rear-view camera 501 is installed on the left A-pillar position outside the vehicle, and the right rear-view camera 502 is installed on the right A-pillar position outside the vehicle.

[0096] Of course, the above-mentioned auxiliary cameras and corresponding angles are only examples and are not used to limit this step.

[0097] Optionally, this embodiment may also provide a storage module to store the off-vehicle video data collected by the auxiliary camera so that it can be retrieved when needed to facilitate the handling of related issues.

[0098] Step S403: Control the target display screen to display the vehicle exterior video data in a display mode corresponding to the driving mode, wherein the target display screen is installed within the driver's field of vision when the driver is looking straight ahead.

[0099] In this embodiment, a display screen is provided that can switch and display the outside video data collected by any auxiliary camera on the vehicle through voice control. For the convenience of subsequent description, this display screen is defined as a target display screen.

[0100] Optionally, the target display screen is a multi-function display screen installed within the driver's field of vision when looking straight ahead; optionally, the target display screen can be the same display screen as the display screen for the previous voice input, or can be a different display screen, which is not limited in this application.

[0101] In this embodiment, a corresponding display mode can be set for each driving mode. After collecting the video data outside the vehicle in the current step, the video data outside the vehicle can be displayed on the target display screen according to the corresponding display mode.

[0102] For example, after the car is started, it is in normal driving mode by default, and the target display screen is displayed according to the display method corresponding to the normal driving mode; if you need to switch back to normal driving mode in other modes, you can use the first voice command "open default mode" to switch the picture on the target display screen back to the display method corresponding to the normal driving mode.

[0103] When encountering certain situations and needing to view the external video data in front of the vehicle, the first voice command "turn on the driving recorder mode" can be used to switch the image on the target display screen to the display mode corresponding to the driving recorder mode.

[0104] When it is necessary to observe the road and other vehicles behind the vehicle, the first voice command "turn on reverse mode" can be used to switch the image on the target display screen to the display mode corresponding to the reverse mode.

[0105] When you need to make a turn or other scene where there are blind spots on the left and right sides that need to be monitored, you can use the first voice command "turn on blind spot monitoring mode" to switch the image on the target display screen to the display mode corresponding to the blind spot monitoring mode.

[0106] When in a parking lot or other scenarios requiring panoramic parking, the first voice command "turn on panoramic parking mode" can be used to switch the image on the target display screen to the display mode corresponding to the panoramic parking mode.

[0107] It should be noted that the above is only an example and is not intended to limit the present application.

[0108] The driving assistance method provided by the present application determines the driving mode represented by the first voice command when receiving the first voice command, collects the video data outside the vehicle through the auxiliary camera corresponding to the driving mode, and controls the target display screen to display the video data outside the vehicle according to the display mode corresponding to the driving mode. The present application provides auxiliary cameras for collecting video data outside the vehicle at different angles for different driving modes, and sets display modes for different driving modes, so that the collected video data outside the vehicle at each angle can be displayed on the target display screen within the driver's line of sight when looking straight ahead according to the corresponding display mode, avoiding visual fatigue caused by the driver moving his line of sight left and right during driving, causing hidden dangers to driving safety, and ensuring driving safety.

[0109] It should be understood that although the present application can provide users with video data outside the vehicle in front of the vehicle, in some scenarios, it may be difficult for users to accurately judge various safety risks such as possible collisions in the future by relying solely on video data. In order to improve the safety of assisted driving, the present application embodiment can also collect video data outside the vehicle in front of the vehicle through a front-view camera installed on the vehicle, and then use a safe driving perception algorithm to perceive and analyze the video data outside the vehicle in front of the vehicle to obtain warning information. Then, while the target display screen displays the video data outside the vehicle in step S403 above, it can also control the target display screen to display warning information at the first preset position to help users avoid risks in advance.

[0110] Optionally, the front-view camera may include a front-view telephoto camera and a front-view wide-angle camera, wherein the front-view telephoto camera is a camera specially designed for long-distance shooting, usually with a longer focal length, and can clearly capture distant targets and provide high-resolution images, and is more suitable for scenes that require long-distance monitoring or shooting; the front-view wide-angle camera is a camera with a wide field of view, and its viewing angle is usually larger than that of an ordinary camera, and can capture a wider range of scenes. It is suitable for scenes that need to capture more environmental information, such as vehicle-mounted panoramic shooting, architectural photography, etc.

[0111] Optionally, the front-view long-range camera can be a high-definition camera with a color and black-and-white switching function, and / or the front-view wide-angle camera can be a high-definition camera with a color and black-and-white switching function, so that it can realize video capture in daytime scenes and display black-and-white videos in night scenes, making recognition clearer and judgment more accurate.

[0112] Optionally, the front-view camera can be installed on the front windshield of the vehicle to capture video data outside the vehicle at a more appropriate angle.

By displaying the basic vehicle information on the target display screen, the driver can see the status of the vehicle more intuitively, which can not only improve driving safety but also enhance the driving experience.

[0117] In order to enable technical personnel in this field to better understand the present application, the process of the previous step S403 "controlling the target display screen to display the external video data according to the display mode corresponding to the driving mode" is introduced below in combination with the normal driving mode, driving recorder mode, reversing mode, blind spot monitoring mode and panoramic parking mode.

[0118] First, if the driving mode is the normal driving mode, the target display screen is controlled to be divided into a first display area and a second display area, and the left rear video data outside the vehicle is displayed in the first display area, and the right rear video data outside the vehicle is displayed in the second display area. The left rear video data outside the vehicle is collected by the left rear-view camera, and the right rear video data outside the vehicle is collected by the right rear-view camera.

[0119] When the vehicle is started, all auxiliary cameras start to work. At this time, it is in normal driving mode by default. In this normal driving mode, the target display screen is divided into two parts, for example, see Figure 6 The structural schematic diagram of the target display screen in the normal driving mode is shown. The target display screen will be divided into a first display area 601 and a second display area 602 in the normal driving mode. The first display area 601 can display the left rear side video data outside the vehicle collected by the left rearview camera, and the second display area 602 can display the right rear side video data outside the vehicle collected by the right rearview camera.

[0120] Optionally, the first display area 601 may also display warning information, such as Figure 6 As shown, the first preset position is in the upper left corner of the target display screen; the second display area 602 can also display basic vehicle information, such as Figure 6As shown, the second preset position is at the upper right corner of the target display screen.

[0121] Second, if the driving mode is the driving recorder mode, the target display screen is controlled to be divided into a third display area, a fourth display area and a fifth display area, the third display area displays the left rear side video data outside the vehicle, the fourth display area displays the front side video data outside the vehicle, and the fifth display area displays the right rear side video data outside the vehicle, wherein the front side video data outside the vehicle is collected by the front-view camera.

[0122] For example, see Figure 7 The structure diagram of the target display screen in the driving recorder mode is shown in FIG. Figure 7 , the target display screen will be divided into a third display area 603, a fourth display area 604 and a fifth display area 605 in the driving recorder mode, wherein the third display area 603 can display the left rear side video data outside the vehicle collected by the left rear view camera, the fifth display area 605 can display the right rear side video data outside the vehicle collected by the right rear view camera, and the fourth display area 604 can display the front side video data outside the vehicle collected by the front view camera.

[0123] Optional, such as Figure 7 The third display area 603 can also display warning information, and the fifth display area 605 can also display basic vehicle information.

[0124] Third, if the driving mode is the reverse mode, the target display screen is controlled to be divided into a sixth display area, a seventh display area and an eighth display area, and the left rear side video data outside the vehicle is displayed in the sixth display area, the rear side video data outside the vehicle is displayed in the seventh display area, and the right rear side video data outside the vehicle is displayed in the eighth display area, wherein the rear side video data outside the vehicle is collected by the rearview camera.

[0125] For example, see Figure 8 The structure diagram of the target display screen in the reverse mode is shown in the figure. Figure 8 , the target display screen will be divided into a sixth display area 606, a seventh display area 607 and an eighth display area 608 in the reversing mode, wherein the sixth display area 606 can display the left rear side video data outside the vehicle collected by the left rearview camera, the eighth display area 608 can display the right rear side video data outside the vehicle collected by the right rearview camera, and the seventh display area 607 can display the rear video data outside the vehicle collected by the rearview camera.

[0126] Optional, such as Figure 8 The sixth display area 606 can also display warning information, and the eighth display area 608 can also display basic vehicle information.

[0127] This embodiment collects the exterior video data behind the vehicle through the rear-view camera, which can help the driver observe other vehicles and road conditions behind the vehicle in a reversing scenario, so that the driver can reverse more safely.

[0128] Fourth, if the driving mode is a blind spot monitoring mode, the target display screen is controlled to be divided into a ninth display area and a tenth display area, and the left side stitched video data outside the vehicle is displayed in the ninth display area, and the right side stitched video data outside the vehicle is displayed in the tenth display area, wherein the left side stitched video data outside the vehicle is obtained by stitching together the data collected by the left rear view camera and the left front view camera, and the right side stitched video data outside the vehicle is obtained by stitching together the data collected by the right rear view camera and the right front view camera.

[0129] For example, see Fig. 9 The structure diagram of the target display screen in the blind spot monitoring mode is shown in FIG. Fig. 9 In the blind spot monitoring mode, the target display screen will be divided into a ninth display area 609 and a tenth display area 610, wherein the ninth display area 609 can display the left side stitched video data outside the vehicle, and the tenth display area 610 can display the right side stitched video data outside the vehicle.

[0130] Optional, such as Fig. 9 The ninth display area 609 can also display warning information, and the tenth display area 610 can also display basic vehicle information.

[0131] Since there are blind spots of a certain range on the left and right sides of the vehicle when the vehicle is changing lanes or turning, this embodiment collects external video data on the left and right sides of the vehicle through the left rear-view camera, the left front-view camera, the right rear-view camera and the right front-view camera to achieve blind spot monitoring, so that the driver can observe other vehicles and road conditions on both sides of the vehicle more intuitively, providing complete field of view information for actions such as overtaking and changing lanes, avoiding traffic accidents and ensuring driving safety.

[0132] Fifth, if the driving mode is a panoramic parking mode, the target display screen is controlled to be divided into an eleventh display area, a twelfth display area, and a thirteenth display area. The left rear side video data outside the vehicle is displayed in the eleventh display area, the full-angle video data outside the vehicle is displayed in the twelfth display area, and the right rear side video data outside the vehicle is displayed in the thirteenth display area, wherein the full-angle video data outside the vehicle is obtained by splicing the data collected by the surround-view camera.

[0133] For example, see Fig.10 The structure diagram of the target display screen in the panoramic parking mode is shown in FIG. Fig.10In the panoramic parking mode, the target display screen will be divided into an eleventh display area 611, a twelfth display area 612 and a thirteenth display area 613, wherein the eleventh display area 611 can display the left rear side video data outside the vehicle collected by the left rearview camera, the thirteenth display area 613 can display the right rear side video data outside the vehicle collected by the right rearview camera, and the twelfth display area 612 can display the full-angle video data outside the vehicle collected by the surround-view camera (i.e., 360° video data outside the vehicle).

[0134] Optional, such as Fig.10 The eleventh display area 611 can also display warning information, and the thirteenth display area 613 can also display basic vehicle information.

[0135] This embodiment uses a 360° surround-view camera to identify other vehicles and road conditions around the vehicle, implements road perception and image stitching through an algorithm, and displays the obtained full-angle video data outside the vehicle on a target display screen, thereby facilitating the driver to perform panoramic parking and improving the driver's driving experience.

[0136] In each driving mode provided above, the present application provides different display methods, so that the driver can switch the display of the camera screen through the first voice command based on his own habits and certain special scenarios (such as panoramic parking or driving recorder scenarios), and while displaying these screens, the assisted driving warning information and vehicle basic information can also be superimposed and displayed in the upper left and upper right corners of the target display screen, which is convenient for the driver to observe the vehicle's surroundings and improves driving safety.

[0137] In the display mode of the target display screen mentioned above, since the target display screen needs to display multiple screens at the same time, each screen may be small, which is not conducive to the driver's observation. In order to further improve the driver's driving experience, this application also configures a voice command representing full-screen display, so that the driver can control the full-screen display of the external video data to be displayed in full screen according to his own needs. At the same time, the warning information and basic vehicle information can be superimposed and displayed in the upper left and upper right corners of the target display screen, such as Fig.11 .

[0138] More specifically, if the present embodiment receives a second voice command representing a full-screen display in driving recorder mode, the target display screen is controlled to display the front video data outside the vehicle in full screen; if the present embodiment receives a third voice command representing a full-screen display in reversing mode, the target display screen is controlled to display the rear video data outside the vehicle in full screen; if the present embodiment receives a fourth voice command representing a full-screen display on the left side in blind spot monitoring mode, the target display screen is controlled to display the left side spliced ​​video data outside the vehicle in full screen; if the present embodiment receives a fifth voice command representing a full-screen display on the right side in blind spot monitoring mode, the target display screen is controlled to display the right side spliced ​​video data outside the vehicle in full screen; if the present embodiment receives a sixth voice command representing a full-screen display in panoramic parking mode, the target display screen is controlled to display the full-angle video data outside the vehicle in full screen.
