[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0049] Aiming at the problem in the prior art that in the Follow Me Home mode of the vehicle, the existing lighting mode is a fixed lighting area and a fixed lighting duration, which is difficult to provide accurate lighting services for users, the present application discloses a vehicle headlight control method. This solution identifies the characteristic information of the target object through the acquisition information of the image acquisition device and the radar device on the vehicle, identifies the moving trajectory of the user based on the characteristic information, and controls the moving trajectory of the lighting area of the vehicle headlights based on the moving trajectory, realizing that in the Follow Me Home mode, the lighting area of the vehicle follows the user's movement, improving the reliability and accuracy of the service.

[0050] For details, see Figure 1 The vehicle light control method disclosed in the embodiment of the present application may include: steps S101-S103.

[0051] Step S101: Obtain image information collected by the front camera of the vehicle, and obtain millimeter wave point cloud information collected by the front radar of the vehicle.

[0052] Intelligent driving system refers to the car equipped with advanced sensors, controllers, actuators, communication modules and other equipment to assist the driver in manipulating the vehicle. At present, more and more cars equipped with intelligent driving systems are entering the consumer market, and the number of models equipped with them is also increasing, which provides a hardware foundation for the optimization of the solution. The multi-sensor fusion solution currently adopted by the intelligent driving system is mainly to play to its strengths and avoid its weaknesses, and to design redundancy to improve the safety factor of the whole vehicle. Among them, the visible light camera has many advantages such as multiple recognition targets, easy installation, and relatively low cost. At the same time, the visual algorithm is developing rapidly. More than ten cameras are arranged in the front, back, left, and right positions of the vehicle to serve various functional scenarios. At the same time, the vehicle is also equipped with millimeter-wave radars in the front and rear bumpers. The millimeter-wave radar has a strong ability to identify moving targets. At the same time, the three millimeter-wave radars in front of the vehicle can basically cover the entire front field of view of the vehicle. In this solution, the front camera and front radar used are the cameras and radars that come with the vehicle.

[0053] When the vehicle meets the starting conditions of the technical solution disclosed in the present application, the first acquisition device and the second acquisition device are started, and images in front of the vehicle are acquired by the first acquisition device, and radar detection is performed in front of the vehicle by the second acquisition device to obtain image information acquired by the first acquisition device and millimeter wave point cloud information acquired by the second acquisition device. The first acquisition device can be a front camera of the vehicle and the second acquisition device can be a front radar of the vehicle.

[0054] Step S102: Obtain characteristic information of the target object based on the image information and the millimeter wave point cloud information, wherein the characteristic information includes at least: coordinate information, speed information and height information.

[0055] After acquiring the image information and the millimeter wave point cloud information, the intelligent driving image processing module determines the target object based on the image information and the millimeter wave point cloud information, and identifies the characteristic information of the target object, wherein the characteristic information of the target object includes at least coordinate information, speed information and height information. The coordinate information is used to determine the user's position, and the speed information is used to determine the user's walking speed. The user's real-time position and walking speed can be determined based on the coordinate information and speed information, and the eye height of the target object can be predicted by the height information. Of course, the position of the eyes can also be determined by image recognition.

[0056] Step S103: Control the irradiation angle of the vehicle headlight based on the feature information.

[0057] In this step, after calculating the coordinate information, speed information, and height information of the target object, control the vehicle headlight based on the coordinate information, speed information, and height information, so that the illumination area of the vehicle headlight follows the target user and avoids direct lighting on the eye position of the target object.

[0058] In the above solution disclosed in the embodiment of the present application, when providing lighting service for the user, obtain the image information collected by the first acquisition device and the millimeter-wave point cloud information collected by the second acquisition device, determine the feature information of the target object based on the image information and the millimeter-wave point cloud information, where the feature information at least includes: coordinate information and speed information, and then control the irradiation angle of the vehicle headlight based on the feature information, thereby realizing providing accurate lighting service for the user.

[0059] The user can select to start the control method of the vehicle lamp disclosed in the present application based on their own needs. Specifically, when obtaining the image information collected by the first acquisition device in front of the vehicle and the millimeter-wave point cloud information collected by the second acquisition device in front of the vehicle, it further includes: determining whether the vehicle meets a preset condition. When the preset condition is met, it indicates that the user has started the control method of the vehicle lamp disclosed in the present application. At this time, execute the above step S101. That is, in this embodiment, the in-vehicle system determines whether the vehicle meets the preset condition. The preset condition refers to the trigger condition of the follow-me-home function. For example, the trigger condition can be that the vehicle is in the off state, the user triggers the light lever in a preset manner, and the user triggers a preset control through the vehicle central control screen. That is, when the user triggers a preset control through the vehicle central control screen, after the vehicle is turned off, press the light switch forward and then release it (i.e., the operation of switching to the high beam), and the instrument will display "Follow-me-home lamp has been enabled". At this time, the vehicle meets the preset condition. In this solution, the user can set on the vehicle central control whether to adopt the vehicle lamp control method provided in this solution or the follow-me-home mode in the prior art.

[0060] In this solution, the purpose of controlling the moving trajectory of the illumination area of the vehicle headlight based on the feature information is to make the position of the illumination area of the vehicle headlight change with the change of the user's position. In this solution, the control of the moving trajectory of the illumination area of the vehicle headlight based on the feature information may specifically include:

[0061] ①. Determine whether the coordinate information is within the illumination range of the first matrix headlight or within the illumination range of the second matrix headlight; when the coordinate information is within the illumination range of the first matrix headlight, control the first matrix headlight to be in the lit state, and when the coordinate information is within the illumination range of the second matrix headlight, control the second matrix headlight to be in the lit state.

[0062] In this solution, the coordinate information refers to the coordinates of the user relative to the vehicle. The origin of the coordinate system where this coordinate is located is the center of the rear axle of the vehicle. In this coordinate system, the left side of the vehicle is the positive X value, the right side of the vehicle is the negative X value, and the Y value is always positive. The coordinate information of the target object relative to the center point of the vehicle's rear drive axle clarifies the position of the target object relative to the vehicle. Since the first matrix headlight and the second matrix headlight (the matrix headlight is the front headlight of the vehicle) of the vehicle are distributed on the left and right sides of the vehicle, the areas that the two matrix headlights can illuminate are also different, that is, within the illumination range of the first matrix headlight and within the illumination range of the second matrix headlight. When both are turned on at the same time, only the matrix headlight whose illumination range covers the coordinate information can provide lighting services for the user, and the other matrix headlight is in an ineffective working condition. Therefore, in this solution, the corresponding matrix headlight can be selected to be lit according to the scene requirements.

[0063] ②. Construct the movement trajectory of the target object based on the coordinate information; predict the predicted position of the target object at the next moment based on the movement trajectory, coordinate information, and the speed information; adjust the illumination angle of the matrix headlight in the lit state based on the predicted position so that the predicted position is in the illuminated state.

[0064] In this solution, in order to better provide lighting services for the user, the position of the user at the next moment can be predicted and illuminated in advance. At this time, the movement trajectory of the target object can be constructed according to the obtained coordinate information. After obtaining the movement trajectory, then predict the predicted position of the target object at the next moment based on the movement trajectory coordinate information and the speed information. After determining the predicted position of the target object at the next moment, adjust the illumination angle of the lit matrix headlight so that the matrix headlight illuminates the predicted position in advance, thereby providing better lighting services for the user.

[0065] The feature information may further include the height information of the target object obtained based on the image information and the millimeter-wave point cloud information. In this solution, the purpose of obtaining the height information of the target object is to estimate the eye height of the target object, and adjust the illumination angle of the matrix headlight based on the eye height, so as to avoid the light of the matrix headlight directly shining into the eyes of the target object. Therefore, in the above method, controlling the illumination angle of the vehicle headlight based on the feature information further includes:

[0066] ③. Predict the eye position of the target object based on the height information, and adjust the irradiation angle of the matrix headlight in the lit state based on the eye height, so that the direct irradiation range of the matrix headlight in the lit state avoids the eye position, so that when the user faces the vehicle, the eyes will not be directly irradiated by the light.

[0067] Of course, in addition to predicting the eye position of the target object based on the height information, the eye position of the user can also be recognized from the image information collected by the first collection device.

[0068] In the technical solution disclosed in another embodiment of the present application, the present application can preset some closing conditions for the headlight matrix. When it is detected that these conditions are met, the lit matrix headlight is controlled to turn off. For example, in this solution, the closing conditions can be: the distance between the coordinate information and the vehicle exceeds the preset distance range, or the duration after the vehicle is locked reaches the preset duration (for example, it can be 30 s). That is, after the solution disclosed in the embodiment of the present application is executed, it is judged whether the distance between the coordinate information and the vehicle exceeds the preset distance range; it is judged whether the duration after the vehicle meets the preset condition is greater than the preset duration; when the preset distance range is exceeded or the preset duration is greater than, the lit vehicle lights are turned off.

[0069] In the technical solution disclosed in another embodiment of the present application, in addition to using the intelligent driving image processing module to determine the target object based on the image information and the millimeter wave point cloud information, the target object can also be determined from the image information and the millimeter wave point cloud information through the vehicle key coordinates. That is, obtain the coordinates where the vehicle key is located, obtain the detection object adapted to the vehicle key coordinates from the image information and the millimeter wave point cloud information, and use this detection object as the target object.

[0070] In the technical solution disclosed in another embodiment of the present application, when the user needs to use the vehicle at night or in other scenarios with relatively dim light, in order to provide lighting services to the user, in this solution, after turning off the vehicle's lit headlights, the solution further includes: when it is detected that the distance between the vehicle key and the vehicle enters within the preset distance range, or when it is detected that the user sends an unlocking instruction to the vehicle through the unlocking button on the vehicle key, determine whether the light intensity is lower than the preset light intensity; when the light intensity is lower than the preset light intensity, it indicates that the vehicle is in a relatively dim environment, and at this time, lighting services need to be provided to the user. At this time, control the headlights to turn on. After the headlights are turned on, turn on the first acquisition device and the second acquisition device on the vehicle, and obtain the scene image collected by the first acquisition device in front of the vehicle; obtain the radar data collected by the second acquisition device in front of the vehicle, and this radar data can also be millimeter-wave point cloud information; based on the scene image and the radar data, identify the characteristic information of the target object, and control the irradiation angle of the headlights based on the characteristic information to provide accurate lighting services for the user approaching the vehicle (the user about to get on the vehicle). Thus, it can be seen that the technical solution disclosed in the present application can not only provide accurate lighting services for the user when getting off the vehicle and going home, but also provide accurate lighting services for the user when getting on the vehicle.
