[0028] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0029] Before the embodiments of the present application are explained in detail, the application scenarios and system architecture involved in the embodiments of the present application are introduced.

[0030] Firstly, the system architecture involved in the embodiments of the present application is introduced.

[0031] The system comprises a center console, an adjusting time interval button, a gear control device, a vehicle-mounted radar, a controller, etc.

[0032] The center console is used to display various display switches on the center console, and based on the operation of the driver on the corresponding display switch, the controller sends a reverse radar distance display on or off instruction, a following time interval value display on or off instruction, and a surrounding obstacle distance display on or off instruction. After the on signal, the obstacle distance warning image is displayed.

[0033] The adjusting time interval button is used to receive the driver's operation instruction and send an adjusting time interval instruction.

[0034] The gear control device is used to control the gear of the vehicle.

[0035] The vehicle-mounted radar is used to obtain environmental data information around the vehicle.

[0036] The controller is used to determine the environmental image, the obstacle image to be displayed after the corresponding display is turned on, and the distance information between the obstacle and the vehicle according to the environmental data information around the vehicle; place the obstacle image to be displayed after the corresponding display is turned on in the environmental image, and mark the distance information between the obstacle and the vehicle, to form an obstacle distance warning image.

[0037] Those skilled in the art should understand that the above system architecture is only an example, and other existing or future components or modules that can be applicable to the present application should also be included in the protection scope of the present application, and are hereby incorporated by reference.

[0038] Finally, the application scenarios related to the embodiments of the present disclosure are introduced.

[0039] The obstacle detection system based on the vehicle-mounted radar can convert the distance data detected by each vehicle-mounted radar into corresponding radar display graphics and display them on the display device of the vehicle to remind the driver to take appropriate measures.

[0040] The existing radar distance display method can display the distance information between the obstacles around the vehicle and the vehicle according to the driving conditions, such as automatically displaying the distance information between the vehicle and the rear obstacle when reversing, and automatically displaying the distance information between the obstacle and the vehicle when the distance between the obstacle and the vehicle around the vehicle is less than the safe distance; however, it cannot display the distance between the vehicle and the rear obstacle, and the distance between the vehicle and the side obstacle during the forward movement of the vehicle, and cannot provide the driver with a reference for judging the distance of the side and rear obstacles, so as to enable the driver to control the vehicle in a timely manner.

[0041] In addition, the existing radar distance display method has the following shortcomings: first, the existing radar distance display method is mostly realized in the form of an image, and errors may occur between the displayed image and the actual distance; second, the existing radar distance display distinguishes the distance of the obstacle by the color of the image on the display interface, without numerical display, and the user is prone to errors in judging the distance of the obstacle, thereby reducing the driving safety and experience of the user.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following further describes the embodiments of the present application in detail with reference to the accompanying drawings.

[0043] The embodiments of the present application provide a control method for obstacle distance display function, and the method comprises the following steps:

[0044] When receiving a reverse radar distance display opening instruction, a distance numerical display opening instruction when following a vehicle, or a surrounding obstacle distance display opening instruction;

[0045] According to the environmental data information around the vehicle, the obstacle image to be displayed after the corresponding display is opened and the distance information between the obstacle and the vehicle are determined;

[0046] The obstacle image to be displayed after the corresponding display is opened is placed in the environmental image, and the distance information between the obstacle and the vehicle is marked to form an obstacle distance reminding image;

[0047] The obstacle distance reminding image is displayed.

[0048] In some embodiments, after receiving the reverse radar distance display opening instruction, the distance numerical display opening instruction when following a vehicle, or the surrounding obstacle distance display opening instruction, the corresponding reverse radar distance display opening, the distance numerical display opening when following a vehicle, or the surrounding obstacle distance display opening is controlled.

[0049] After the reverse radar distance display is opened, the obstacle image to be displayed is the obstacle image behind the vehicle, the obstacle image behind the vehicle is placed in the environmental image, and the distance between the obstacle behind the vehicle and the vehicle is marked to form an obstacle distance reminding image.

[0050] After the distance numerical display opening when following a vehicle is opened, the obstacle image to be displayed is the obstacle image in front of the vehicle, the obstacle image in front of the vehicle is placed in the environmental image, and the distance between the obstacle in front of the vehicle and the vehicle is marked to form an obstacle distance reminding image.

[0051] After the surrounding obstacle distance display is opened, the obstacle image to be displayed is the obstacle image on the side of the vehicle, the obstacle image on the side of the vehicle is placed in the environmental image, and the distance between the obstacle on the side of the vehicle and the vehicle is marked to form an obstacle distance reminding image.

[0052] In some embodiments, the display color of the obstacle distance reminding image is determined according to the distance information between the obstacle to be displayed after the corresponding display is turned on and the vehicle; and the obstacle distance reminding image is displayed according to the determined display color.

[0053] Different distances correspond to different colors, and the reminding image is displayed by different colors, which can provide auxiliary reference for the driver to obtain the distance information of the obstacles around the vehicle.

[0054] As shown in Figure 1 The vehicle-mounted radar installed on the vehicle is used to obtain the environmental data information around the vehicle; each vehicle-mounted radar establishes its own real vehicle scene coordinate system according to the specific installation position, and the radar collects the environmental data information around the vehicle according to the corresponding real vehicle scene coordinate system, which can include the distance and angle data of the obstacles around the vehicle. The environmental data information collected by the radar is converted to the corresponding pixel coordinate system to form a rendering implementation scene and obtain an environmental image. At the same time, the obstacle image is determined by searching a database, and the distance value between the surrounding obstacles and the vehicle is calculated. When a corresponding display opening instruction is received, the corresponding display is turned on, the distance between the obstacle to be displayed after the corresponding display is turned on and the vehicle is determined, the obstacle image to be displayed after the corresponding display is turned on is placed in the environmental image, and the distance information between the obstacle and the vehicle is marked to form an obstacle distance reminding image, and the display color of the obstacle distance reminding image is determined. Then, the obstacle distance reminding image is displayed on the center console with the determined display color, and the distance between the obstacle and the vehicle is displayed by a numerical value, so that the driver can more intuitively understand the situation around the vehicle. Only the distance information obtained by the radar is used to generate the distance reminding image, and no other components need to be installed.

[0055] In some embodiments, each display switch is displayed on the center console, and when a corresponding display switch opening signal on the center console is received, it is determined that a corresponding display opening instruction is received.

[0056] As shown in Figure 3As shown, the display switches on the center console include a radar distance display switch, a reverse radar distance display switch, a following distance value display switch, and a surrounding obstacle distance display switch. During vehicle travel, the driver controls the center console to send corresponding display on or off signals by turning on or off the display switches on the center console. When the center console receives a display on or off signal, it determines that a corresponding display on or off instruction has been received. For example, when the driver turns on the radar distance display switch on the center console, the center console sends a following distance value display on instruction, a reverse radar distance display on instruction, and a surrounding obstacle distance display on instruction, and the following distance value display function, the reverse radar distance display function, and the surrounding obstacle distance display function are simultaneously turned on, and the distance information between the vehicle and the obstacles in front of the vehicle, the side obstacles, and the rear obstacles is simultaneously displayed in the obstacle distance warning image. When the driver turns off or on the reverse radar distance display switch on the center console, the center console sends a reverse radar distance display off or on signal. When the driver turns off or on the following distance value display switch on the center console, the center console sends a following distance value display off or on signal. When the driver turns off or on the surrounding obstacle distance display switch on the center console, the center console sends a surrounding obstacle distance display off or on signal, where the surrounding obstacle distance display switch is represented by XXX distance display. When the driver turns off the radar distance display switch on the center console, the center console sends a following distance value display off instruction, a reverse radar distance display off instruction, and a surrounding obstacle distance display off instruction, and the following distance value display function, the reverse radar distance display function, and the surrounding obstacle distance display function are simultaneously turned off.

[0057] The driver can control the display switches on the center console according to personal needs to display the distance between the vehicle and the obstacles.

[0058] In some embodiments, when the center console receives an adjustment distance instruction sent by the adjustment distance button, it determines that a following distance value display on instruction has been received, and the following distance value display function is turned on to display the distance between the vehicle and the obstacles in front of the vehicle.

[0059] In some embodiments, when the center console receives a reverse instruction, it determines that a reverse radar distance display on instruction has been received.

[0060] When the center console receives a reverse instruction, the vehicle enters a reverse mode by default, and the reverse radar distance display function is turned on to display the distance between the vehicle and the obstacles behind the vehicle, providing a distance reference for the driver when reversing.

[0061] For example, when the driver turns on the radar distance display switch on the center console, the center console sends a following distance value display on instruction, a reverse radar distance display on instruction, and a surrounding obstacle distance display on instruction, and the following distance value display function, the reverse radar distance display function, and the surrounding obstacle distance display function are simultaneously turned on, and the distance information between the vehicle and the obstacles in front of the vehicle, the side obstacles, and the rear obstacles is simultaneously displayed in the obstacle distance warning image. Figure 2As shown, when the reverse instruction is received, the control reverse radar distance display is turned on, the obstacle distance reminding image contains the rear obstacle of the vehicle, the distance information between the rear obstacle of the vehicle and the vehicle, and the reverse auxiliary line, the reverse auxiliary line includes a plurality of lines, the distance between the plurality of reverse auxiliary lines and the vehicle is different, and the display color of the plurality of reverse auxiliary lines is different, such as the reverse auxiliary line in green, yellow and red.

[0062] In some embodiments, when there is an obstacle with a distance less than a set safety distance between the vehicle and the vehicle around the vehicle, the control surrounding obstacle distance display is turned on, and when the vehicle passes through a more crowded road section, the driver is provided with reminding information;

[0063] Then, when there is no obstacle with a distance less than a set safety distance between the vehicle and the vehicle around the vehicle, or the surrounding obstacle distance display function is turned off after receiving the surrounding obstacle distance display function turning off instruction.

[0064] The embodiment of the present application provides a kind of obstacle distance display function control method, and driver can open or close various distance display functions by operating each display switch on center console, and then according to the distance display function opened by driver, the distance information between corresponding obstacle and vehicle is displayed, to provide reference for driver.The distance value between obstacle and vehicle is marked in the displayed obstacle distance reminding image, so that driver can more intuitively observe the situation around the vehicle.
