[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The headlights of existing vehicles have the following problems: (1) Single function: Traditional headlights mainly provide basic lighting services, such as high beam, low beam, turn signal, etc., and cannot realize more vehicle functions, such as failing to meet the driver's needs for emotional expression and personalized customization. (2) Lack of safety tips: Although the existing headlight system has some basic safety assistance functions, the amount of information it provides is still insufficient in a complex and changing traffic environment, making it difficult to meet the driver's pursuit of higher safety. (3) Limited scalability: The architecture of the traditional headlight system is relatively closed, and it is difficult to expand functions, making it difficult to adapt to the future development trend of intelligence and networking. (4) Insufficient user experience: Due to the single function and lack of personalization, the existing headlight system has obvious deficiencies in improving the driving experience and cannot bring drivers a richer and more interesting driving experience.

[0045] To solve the above problems, Figure 1 As shown, the present application provides a vehicle light control method. This embodiment takes the method applied to a vehicle smart light system as an example. The method includes the following steps:

[0046] Step 102: Acquire the surrounding environment information of the vehicle and user setting information, where the user setting information includes projection content and lighting control parameters;

[0047] In this embodiment, the surrounding environment information includes image information of the vehicle's surrounding environment, the distance between the vehicle and surrounding vehicles, the vehicle's speed, and the movement speed of traffic participants around the vehicle, etc.;

[0048] The vehicle lamp of the present application has not only a lighting function, but also a projection function, and the projection content refers to the image content, animated image content or video content projected when the vehicle lamp is used as a projection lamp;

[0049] Lighting control parameters refer to the lighting parameters set for the headlights when they perform their lighting functions.

[0050] Step 104: determining target lighting control parameters based on the surrounding environment information and the lighting control parameters; generating target projection content based on the surrounding environment information and the projection content;

[0051] Similarly, the target light control parameters refer to the lighting parameters set for the headlights when they are used for lighting. The target projection content refers to the image content, animated image content, or video content projected by the headlights when they are used as projection lamps;

[0052] It can be seen that the present application not only sets the target light control parameters based on the light control parameters set by the user to control the light of the car, but also sets the target light control parameters based on the surrounding environment information and the light control parameters set by the user to control the light of the car. In this way, the light control parameters can be intelligently adjusted based on the vehicle's surrounding environment information, thereby enhancing driving safety.

[0053] At the same time, the present application sets the target projection content based on the surrounding environment information and the projection content set by the user to control the vehicle projection content to adapt to the current environment.

[0054] Step 106: Based on the target light control parameters, the vehicle light equipment is controlled, and the vehicle light equipment is controlled to project the target projection content according to the preset projection parameters.

[0055] After the present application obtains the vehicle's surrounding environment information and user setting information, the user setting information includes projection content and light control parameters, so that the target light control parameters can be determined based on the surrounding environment information and the light control parameters, and then the target projection content can be generated based on the surrounding environment information and the projection content, so that the vehicle's headlight equipment can be controlled based on the target light control parameters to achieve the lighting function, and at the same time, the headlight equipment is controlled to project the target projection content according to the preset projection parameters, so that the headlight equipment has a projection function, thereby improving the functional diversity of the headlight equipment.

[0056] The following is a detailed description of the present application. The present application's smart car light system uses vehicle-mounted light application technology to enable the car lights to have not only lighting functions, but also projection functions, which can project customized information such as distance reminders of the vehicle ahead, patterns, expressions, text, weather, etc., and even realize car light parties and car light concerts, thereby providing users with a rich and diverse emotional interaction experience. Figure 2 The smart car lighting system based on service-oriented architecture (SOA) specifically includes the following four modules: environment perception service module, user interaction service module, lighting control service module, and projection display service module. The following describes the executable steps of these four modules:

[0057] The perception service module is used to obtain the vehicle's surrounding environment information, provide the surrounding environment information to the lighting control service module to generate target lighting control parameters for lighting control, and provide the surrounding environment information to the projection display service module to generate and project target projection content. After the perception service module is used to obtain the vehicle's surrounding environment information, it also needs to process the surrounding environment information, specifically:

[0058] In one embodiment of the present application, after obtaining the surrounding environment information of the vehicle, the method further includes: preprocessing the surrounding environment information; identifying key information of the preprocessed surrounding environment information to obtain road environment information, weather condition information and obstacle information; and constructing the motion trajectory of dynamic obstacles based on the three-dimensional space modeling technology and the dynamic obstacle information of the obstacle information. Figure 3 , the perception service module can execute the following steps:

[0059] Sensor integration: Multiple sensors are installed on the vehicle, such as cameras, radars, lidars, ultrasonic sensors, etc., to obtain information about the surrounding environment. Multiple sensors are integrated into the vehicle to ensure that they can cover the area that needs to be sensed and establish a communication connection with the environmental perception service module.

[0060] Data collection: The environmental perception service module collects surrounding environment information in real time through the sensor interface, including image frames, distance measurement values, velocity vectors, etc. Then the collected surrounding environment information is preprocessed, such as denoising, filtering, time synchronization, etc., to improve the quality and accuracy of the data.

[0061] Data processing and analysis: The above-mentioned key information identification of the pre-processed surrounding environment information is performed to obtain road environment information, weather condition information and obstacle information, specifically including: for the surrounding environment image in the pre-processed surrounding environment information, the image processing algorithm is used to pre-process and identify key information of the surrounding environment image, and key information such as road environment information (such as road signs), obstacle information, pedestrians, and weather condition information is extracted. For the radar data in the pre-processed surrounding environment information, three-dimensional space modeling is performed based on the three-dimensional space modeling technology to obtain the depth information of the surrounding environment, and key information identification is performed on the radar data to obtain obstacle information. The obstacle information includes dynamic obstacle information and static obstacle information. Based on the three-dimensional space modeling technology and the dynamic obstacle information of the obstacle information, the motion trajectory of the dynamic obstacle is constructed.

[0062] Then, multiple sensor data (i.e., key information such as road environment information, obstacle information, pedestrians, and weather conditions obtained by the above-mentioned surrounding environment image processing, as well as depth information of the surrounding environment and motion trajectory of dynamic obstacles obtained by radar data processing) are fused to obtain fused data, which can improve the robustness and accuracy of environmental perception.

[0063] Decision-making and output: Decision-making and judgment are made based on the integrated data, such as identifying obstacles ahead, pedestrians crossing the road and other emergencies. The decision results are then output to the lighting control service module and the projection display service module in the form of a standard interface so that they can adjust the lamp effect and projection content according to the environmental conditions.

[0064] The user interaction service module is responsible for processing the interaction between the user and the smart car light system, allowing the user to easily set the projection content and adjust the lighting control parameters. Figure 4 ,The main implementation steps of the user interaction service module are as follows:

[0065] Interface design: Design an intuitive and easy-to-use user interface based on user needs and system functions. The interface should include necessary operating elements, such as touch screen buttons, sliders, voice input prompts, etc.

[0066] Interaction logic development: Based on the operation instructions input by the user through the user interaction interface, such as clicking buttons, sliding the screen, voice input, etc., the corresponding service interface is called according to the user operation instructions, and the user operation instructions are passed to the lighting control service module and the projection display service module;

[0067] For example, the user increases or decreases the light brightness by sliding a slider on the control interface; the user turns on the light by pressing a button on the touch screen; the user adjusts the light illumination range by voice input prompts.

[0068] Feedback mechanism implementation: Implement user operation feedback mechanism, such as through interface display, sound prompts, etc., to promptly feedback operation results and system status to users.

[0069] Personalized setting options are supported, allowing users to adjust projection parameters and lighting control parameters according to their preferences and needs, such as the style of the projected content, projection image brightness, projection image contrast, lighting brightness, etc. The user's personalized settings are then saved to the system so that they can be automatically loaded the next time they are started.

[0070] User authority management: In one of the embodiments of the present application, before obtaining the vehicle's surrounding environment information and user setting information, the method also includes: verifying the user's authority; if the authority verification is passed, receiving the information setting instructions input by the user, and performing corresponding settings based on the information setting instructions; if the preset time is reached and the setting is not completed, displaying the setting progress.

[0071] Implement the user authority management function to ensure that only users with corresponding authority can perform user personalization settings. When the user authority verification is passed, receive the information setting instruction input by the user, which is used by the user to set the above user setting information.

[0072] For settings of sensitive operations, provide authentication mechanisms such as password input, fingerprint recognition, etc. for identity authentication.

[0073] In this embodiment, in the implementation of the above feedback mechanism, when the preset time is reached and the setting is not completed, that is, when no user operation feedback is received after the preset time is reached, a progress bar or waiting prompt is provided to enhance the user experience.

[0074] Reference Figure 5 The lighting control service module is used to determine the target lighting control parameters based on the surrounding environment information and the lighting control parameters. In one embodiment, the target lighting control parameters are determined based on the surrounding environment information and the lighting control parameters, including: determining the lighting brightness, lighting contrast, lighting angle and lighting range based on the road environment information, weather condition information and static obstacle information in the obstacle information, motion trajectory and lighting control parameters. Figure 5 ,The main implementation steps of the lighting control service module are as follows:

[0075] Interface definition and data reception: define interfaces for interacting with the environment perception service module, user interaction service module, and projection display service module. Then receive the surrounding environment information from the environment perception service module and the user setting information (such as light brightness and light illumination range) from the user interaction service module.

[0076] Data processing and analysis: As mentioned above, the surrounding environment information is processed to obtain fusion data of multi-sensor data, and the fusion data includes road environment information, weather condition information, static obstacle information in obstacle information, and motion trajectory, wherein the road environment information refers to lane lines, lane markings, traffic light signs, road buildings, road rocks and trees, etc.; weather condition information includes: sunny days, rainy days, thunder, lightning, etc.; static obstacle information in obstacle information refers to stones on the stationary road, vehicles on the stationary road, etc.; dynamic obstacle information in obstacle information refers to moving vehicles, pedestrians, etc., and the motion trajectory obtained from the dynamic obstacle information refers to the motion trajectory of vehicles or pedestrians;

[0077] The lighting control service module analyzes the received fusion data and identifies the vehicle's current driving environment (such as a straight road, a curve, or a tunnel), weather conditions (such as rainy days), and the operation of obstacles as analysis results;

[0078] Lighting control strategy formulation: According to the analysis results and in combination with the lighting control parameters set by the user, the target lighting control parameters are determined to formulate a specific lighting control strategy; the target lighting control parameters include lighting brightness, lighting contrast, lighting angle and lighting range. The lighting angle refers to the angle of the lighting relative to the ground.

[0079] Specific lighting control strategies can be: for example, increasing the lighting intensity on the inside of a curve when driving on a curve; turning on the fog lights and adjusting the angle of the headlights to prevent glare on rainy days.

[0080] Command generation and issuance: Generate specific control commands based on the lighting control strategy, and then issue the control commands to the lighting control unit (such as LED driver, projector, etc.) in the vehicle control system to adjust the light brightness, light contrast, lighting angle and lighting range.

[0081] Feedback and optimization: Receive feedback from the lighting control unit (such as execution status, error information, etc.), and then optimize and adjust the lighting control strategy based on the feedback information to ensure the stability and reliability of the system.

[0082] In this embodiment, the lighting control service module can adjust the lighting control parameters based on the current surrounding environment of the vehicle and user setting information, so that the vehicle can adapt to the current surroundings and user settings to adjust the lighting control parameters, thereby realizing intelligent control of the lights. It can intelligently turn on or off the low beam (or high beam), and at the same time adjust the light brightness and lighting range to facilitate safe driving of the vehicle.

[0083] Reference Figure 6The projection display service module is used to generate target projection content based on surrounding environment information, projection content and external input information (such as navigation information, entertainment content, etc.). The projection content is static projection content; in one embodiment, the target projection content is generated based on the surrounding environment information and the projection content, including: obtaining current context information and dynamic projection content, the current context information includes occasion context and date context; based on road environment information, weather condition information, current context information, dynamic projection content and static projection content, the target projection content is generated.

[0084] Interface definition and data reception: define the interfaces for the lighting control service module to interact with the environment perception service module, user interaction service module, etc., to ensure that data and instructions from these modules can be received. Receive the surrounding environment information sent by the environment perception service module, receive the projection content set by the user from the user interaction service module, and receive external input information.

[0085] Data processing and content generation: Analyze the road environment information, weather condition information, etc. in the received fusion data to obtain analysis results to understand the current driving environment's demand for projection display, then obtain the current situation information and dynamic projection content, comprehensively consider the analysis results, current situation information and dynamic projection content combined with the static projection content set by the user, and generate the target projection content;

[0086] The current context information includes occasion context and date context. The occasion context can be a specific occasion, etc., and the date context can be holidays, etc. The static projection content can be patterns, expressions, and text, etc. The dynamic projection content can be animated images and videos, which can be the above-mentioned external input information, specifically the vehicle's real-time navigation information and / or entertainment content that needs to be played, and the entertainment content that needs to be played can be video content.

[0087] The target projection content includes simple indicator arrows, lane markings, speed limit signs, or more complex navigation maps, entertainment videos, etc. Then the target projection content is processed as necessary, such as format conversion, size adjustment, color correction, etc., to ensure that it can be displayed correctly and clearly on the projection display device.

[0088] Projection parameter setting: In one embodiment, before controlling the vehicle lighting device to project the target projection content according to preset projection parameters, the method also includes: setting the projection angle, projection position and projection distance based on the current posture of the vehicle and road environment information, and using the projection angle, projection position and projection distance as projection parameters.

[0089] According to the current position, posture and road conditions of the vehicle, the best projection angle, projection distance and projection position are calculated, and the parameters of the projection display device (i.e., projection lamp) are set (in fact, the focal length, projection content ratio, etc. of the projection lamp are adjusted), so that the projection lamp projects the above projection content according to the projection angle, projection position and projection distance;

[0090] At the same time, you can also set the brightness, contrast, and focal length of the content projected by the projector to optimize the display effect.

[0091] Projection display execution: Send the target projection content to the projection display device (such as car projector, projection lamp, etc.), monitor the execution status, and ensure that the projection content can be displayed correctly.

[0092] Feedback and optimization: Receive feedback information (such as execution status, error information, etc.) from the projection display device, and optimize the projection display strategy based on the feedback information, such as adjusting projection parameters, updating projection content, etc. Then monitor the surrounding environment information and user setting information changes in real time, and dynamically adjust the projection display service.

[0093] A possible scenario of the present application is that when driving at night, the smart headlight system automatically identifies the distance to the vehicle in front based on the surrounding environment information, and displays a safe distance prompt by projecting it on the road surface between the two vehicles to reduce the risk of rear-end collision.

[0094] Another possible scenario of the present application is that the user customizes the projection content for special occasions or holidays through the in-vehicle application. Then when the holiday arrives or the vehicle is in a special occasion, the headlights can project celebratory patterns or blessings to create a festive atmosphere.

[0095] Another possible scenario of the present application is that the smart car lighting system automatically identifies the current weather based on the surrounding environment information and displays the weather warning information by projecting it onto the road surface.

[0096] In this embodiment, the car lights have a projection function and can generate target projection content based on the surrounding environment information and the projection content, so that the projection content adapts to the surrounding environment and the user-defined projection content. It can project reminders of the distance to the vehicle in front and customized information such as patterns, expressions, text, weather, etc., and even realize car light parties and car light concerts, thereby providing users with a rich and diverse emotional interaction experience.

[0097] In summary, refer to Figure 7 The vehicle control system of this application can generally provide the following services:

[0102] Lighting control service module, ambient environment information and lighting control parameters, determine target lighting control parameters, and automatically adjust parameters such as the brightness and illumination range of the lights;

[0103] The projection limited-time service module generates target projection content based on the surrounding environment information and projection content, and projects emotional light language, custom patterns, text and other information onto the road ahead or the vehicle body to achieve rich visual effects.

[0104] Integration testing: Integrate various service modules to ensure normal communication and data exchange between them; conduct comprehensive functional testing, performance testing, and safety testing to verify the stability and reliability of the smart car lighting system; fix problems and make optimization adjustments based on test results to improve user experience.

[0105] Deployment and launch: Integrate the smart lighting system into the vehicle and conduct field testing and verification; based on user feedback, continuously optimize and iterate system functions.
