[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] The existing vehicle lights have the following problems: (1) Limited functionality: Traditional vehicle lights mainly provide basic lighting services, such as high beams, low beams, and turn signals, 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 prompts: Although the existing vehicle light system has some basic safety assistance functions, in the complex and ever-changing traffic environment, the amount of information it provides is still insufficient, making it difficult to meet the driver's pursuit of higher safety. (3) Limited scalability: The architecture of the traditional vehicle light system is relatively closed, making it difficult to expand its functions and adapt to the future development trend of intelligence and connectivity. (4) Insufficient user experience: Due to the limited functionality and lack of personalization, the existing vehicle light system is significantly insufficient in improving the driving experience and cannot bring drivers a richer and more interesting driving experience.

[0045] To solve the above problems, such as Figure 1 As shown, this application provides a vehicle lighting control method. This embodiment illustrates the application of this method to a vehicle's intelligent lighting system. The method includes the following steps:

[0046] Step 102: Obtain information about the vehicle's surrounding environment and user settings, including 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 speed, and the movement speed of traffic participants around the vehicle.

[0048] The vehicle headlights of this application not only have lighting functions, but also projection functions. The projection content refers to the image content, animated content, or video content projected by the vehicle headlights when they are used as projection lights.

[0049] Lighting control parameters refer to the lighting parameters set for vehicle lights when they are used for illumination.

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

[0051] Similarly, target lighting control parameters refer to the lighting parameters set for the vehicle lights when they are used for illumination. Target projection content refers to the image, animation, or video content projected by the vehicle lights when they are used as projection lights.

[0052] As can be seen, this application does not only set the target lighting control parameters based on the user-defined lighting control parameters to control the vehicle lights, but also sets the target lighting control parameters based on both the surrounding environment information and the user-defined lighting control parameters. This allows for intelligent adjustment of the lighting control parameters based on the vehicle's surrounding environment information, thereby enhancing driving safety.

[0053] Meanwhile, this application sets the target projection content based on surrounding environmental information and the projection content set by the user, so as to control the vehicle projection content to adapt to the current environment.

[0054] Step 106: Based on the target lighting control parameters, control the vehicle's headlights and project the target content according to the preset projection parameters.

[0055] After obtaining the vehicle's surrounding environment information and user settings information, including the projection content and lighting control parameters, this application can determine the target lighting control parameters based on the surrounding environment information and lighting control parameters. Then, based on the surrounding environment information and projection content, the target projection content is generated. Based on the target lighting control parameters, the vehicle's headlights are controlled to achieve the lighting function. At the same time, the headlights are controlled to project the target projection content according to the preset projection parameters, giving the headlights a projection function and improving the functionality of the headlights.

[0056] The following is a detailed explanation of the proposed solution. This intelligent vehicle lighting system utilizes in-vehicle light application technology to enable vehicle lights to not only provide illumination but also projection capabilities. It can project customized information such as distance warnings to vehicles ahead, patterns, expressions, text, and weather, and even create vehicle light parties and concerts, thereby providing users with a rich and diverse emotional interactive experience. (Refer to...) Figure 2 The intelligent vehicle lighting system based on service-oriented architecture (SOA) specifically includes the following four modules: environmental perception service module, user interaction service module, lighting control service module, and projection display service module. The executable steps of each of these four modules are explained below:

[0057] The perception service module acquires information about the vehicle's surrounding environment, provides this information to the lighting control service module to generate target lighting control parameters, and provides the surrounding environment information to the projection display service module to generate and project target content. After acquiring the surrounding environment information, the perception service module also needs to process this information, specifically:

[0058] In one embodiment of this application, after acquiring the vehicle's surrounding environment information, the method further includes: preprocessing the surrounding environment information; identifying key information from the preprocessed surrounding environment information to obtain road environment information, weather condition information, and obstacle information; and constructing the motion trajectory of the dynamic obstacle based on dynamic obstacle information using 3D spatial modeling technology and obstacle information. (Refer to...) Figure 3 The steps that the perception service module can execute are as follows:

[0059] Sensor integration: Multiple sensors, such as cameras, radar, lidar, and ultrasonic sensors, are installed on the vehicle to acquire information about the surrounding environment. Integrating these sensors into the vehicle ensures they can cover the area requiring perception and establish communication connections with the environmental perception service module.

[0060] Data Acquisition: The environmental perception service module collects surrounding environmental information in real time through sensor interfaces, including image frames, distance measurements, and velocity vectors. The acquired environmental information is then preprocessed, including noise reduction, filtering, and time synchronization, to improve data quality and accuracy.

[0061] Data Processing and Analysis: The above-mentioned key information identification of the preprocessed surrounding environment information yields road environment information, weather condition information, and obstacle information. Specifically, this includes: for the surrounding environment images in the preprocessed surrounding environment information, image processing algorithms are used to preprocess and identify key information, extracting key information such as road environment information (e.g., road signs), obstacle information, pedestrian information, and weather condition information. For the radar data in the preprocessed surrounding environment information, 3D spatial modeling technology is used to perform 3D spatial modeling to obtain the depth information of the surrounding environment. Key information identification is then performed on the radar data to obtain obstacle information, including dynamic and static obstacle information. Based on 3D spatial modeling technology and the dynamic obstacle information, the motion trajectory of dynamic obstacles is constructed.

[0062] Then, by fusing data from multiple sensors (i.e., key information such as road environment information, obstacle information, pedestrian information, and weather conditions obtained from the above-mentioned image processing of the surrounding environment, as well as depth information of the surrounding environment and the movement trajectory of dynamic obstacles obtained from radar data processing) to obtain fused data, the robustness and accuracy of environmental perception can be improved.

[0063] Decision-making and output: Based on the integrated data, decisions are made, such as identifying emergency situations like obstacles ahead or pedestrians crossing the road. The decision results are then output to the lighting control service module and the projection display service module via a standard interface, so that they can adjust the lighting effects and projected content according to the environmental conditions.

[0064] The user interaction service module handles the interaction between the user and the intelligent vehicle lighting system, enabling users to easily set the projected content and adjust the lighting control parameters. (See reference...) Figure 4 The main implementation steps of the user interaction service module are as follows:

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

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

[0067] For example, users can increase or decrease the brightness of the lights by using a slider on the control interface; users can turn on the lights by using a touchscreen button; and users can adjust the range of light illumination by using voice input prompts.

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

[0069] Personalized settings are supported, allowing users to adjust projection and lighting control parameters according to their preferences and needs, such as the style of the projected content, the brightness of the projected image, the contrast of the projected image, and the brightness of the lights. The user's personalized settings are then saved to the system for automatic loading upon the next startup.

[0070] User permission management: In one embodiment of this application, before obtaining the vehicle's surrounding environment information and user settings information, the method further includes: verifying the user's permissions; if the permission verification is successful, receiving the information setting instruction input by the user and making corresponding settings based on the information setting instruction; if a preset time expires and the settings are not completed, displaying the setting progress.

[0071] Implement user permission management functionality to ensure that only users with the corresponding permissions can perform personalized user settings. After the user permission verification is successful, receive the information setting instructions input by the user, which are used by the user to set the aforementioned user settings information.

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

[0073] In this embodiment, when the preset time has elapsed and the setting has not been completed (i.e., no user operation feedback has been received after the preset time has elapsed), 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 target lighting control parameters based on surrounding environmental information and lighting control parameters. In one embodiment, determining the target lighting control parameters based on surrounding environmental information and lighting control parameters includes: determining light brightness, light contrast, headlight illumination angle, and headlight illumination range based on road environment information, weather condition information, and static obstacle information, movement trajectory, and lighting control parameters. (Refer to...) Figure 5 The main implementation steps of the lighting control service module are as follows:

[0075] Interface Definition and Data Reception: Define interfaces for interaction with the environmental perception service module, user interaction service module, and projection display service module, respectively. Then, receive surrounding environmental information from the environmental perception service module and user settings 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 environmental information is processed to obtain fused data from multiple sensors. The fused data includes road environment information, weather condition information, static obstacle information, and motion trajectories. Road environment information refers to lane lines, lane markings, traffic light signs, road structures, road rocks, and trees, etc.; weather condition information includes: sunny days, rainy days, thunder, lightning, etc.; static obstacle information refers to stationary stones and vehicles on the road, etc.; dynamic obstacle information refers to moving vehicles and 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 fused data to identify the vehicle's current driving environment (such as straight road sections, curves, or tunnels), weather conditions (such as rainy days), and the operation of obstacles, and uses these as analysis results.

[0078] Lighting control strategy formulation: Based on the analysis results and combined with the lighting control parameters set by the user, the target lighting control parameters are determined, and a specific lighting control strategy is formulated. The target lighting control parameters include light brightness, light contrast, headlight beam angle, and headlight beam range. The headlight beam angle refers to the angle of the headlights relative to the ground.

[0079] Specific lighting control strategies could include, for example, increasing the lighting intensity on the inside of a curve when driving through a bend; and turning on fog lights and adjusting the headlights' beam angle to prevent glare in rainy weather.

[0080] Command generation and issuance: Based on the lighting control strategy, specific control commands are generated and then issued to the vehicle lighting control unit (such as LED driver, projector, etc.) in the vehicle control system to adjust the brightness, contrast, beam angle, and beam range of the lights.

[0081] Feedback and optimization: Receive feedback information from the vehicle 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 environment around the vehicle and user settings, so that the vehicle can adapt to the current environment and user settings to adjust the lighting control parameters, realize intelligent control of the vehicle lights, and can intelligently turn on or off the low beam headlights (or high beam headlights), while adjusting the brightness and illumination range of the lights to facilitate safe driving.

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

[0084] Interface Definition and Data Reception: Define the interfaces for the lighting control service module to interact with the environmental perception service module, user interaction service module, etc., ensuring that it can receive data and instructions from these modules. This includes receiving ambient environment information sent by the environmental perception service module, receiving user-set projection content sent by the user interaction service module, and receiving external input information.

[0085] Data processing and content generation: Analyze road environment information, weather conditions and other information in the received fused data to obtain analysis results, so as to understand the current driving environment’s needs for projection display. Then, obtain current context information and dynamic projection content, and comprehensively consider the analysis results, current context information and dynamic projection content, combined with the static projection content set by the user, to generate target projection content.

[0086] The current context information includes the occasion context and the date context. The occasion context can be a specific occasion, and the date context can be a holiday. Static projection content can be patterns, emoticons, and text, while dynamic projection content can be animated images and videos. It can also be the aforementioned external input information, specifically real-time vehicle navigation information and / or entertainment content to be played. The entertainment content to be played can be video content.

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

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

[0089] Based on the vehicle's current position, attitude, and road conditions, the optimal projection angle, projection distance, and projection position are calculated. The parameters of the projection display device (i.e., the projection lamp) are then set (which is actually adjusting the focal length, projection content ratio, etc. of the projection lamp) so that the projection lamp projects the above-mentioned content according to the projection angle, projection position, and projection distance.

[0090] Additionally, you can adjust the brightness, contrast, and focal length of the projected content to optimize the display.

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

[0092] Feedback and Optimization: The system receives feedback information from the projection display device (such as execution status and error messages), and optimizes and adjusts the projection display strategy based on this feedback, such as adjusting projection parameters and updating projected content. It then monitors changes in the surrounding environment and user settings in real time, dynamically adjusting the projection display service accordingly.

[0093] One possible scenario for this application is that, when driving at night, the intelligent vehicle lighting system automatically identifies the distance to the vehicle in front based on the surrounding environment information, and displays a safe distance warning by projecting it onto the road surface between the two vehicles, thereby reducing the risk of rear-end collisions.

[0094] Another possible scenario for this application is that users can customize the projection content for special occasions or holidays through an in-vehicle application. Then, when holidays arrive or the vehicle is in a special situation, the headlights can project celebratory patterns or blessings to create a festive atmosphere.

[0095] Another possible scenario for this application is that the intelligent vehicle lighting system automatically identifies the current weather based on surrounding environmental information and displays weather warning information by projecting it onto the road surface.

[0096] In this embodiment, the vehicle headlights have a projection function, which can generate target projection content based on surrounding environmental information and the projection content, so that the projection content is adapted to the surrounding environment and user-defined projection content. It can project forward distance reminders and custom information such as patterns, expressions, text, and weather, and even realize headlight parties and headlight concerts, thereby providing users with a rich and diverse emotional interaction experience.

[0097] In summary, referring to Figure 7 The vehicle control system described in this application can provide the following services in summary:

[0098] Requirements Analysis: Define the functional requirements of the intelligent vehicle lighting system, including projection display, emotional lighting language, customized information projection, and emotional interactive experience; analyze the vehicle's electrical system, in-vehicle network, and user operating habits to determine the system interface and data exchange standards.

[0099] Architecture Design: The system adopts an SOA architecture, dividing the intelligent vehicle lighting system into multiple independent service modules, including an environmental perception service module, a user interaction service module, a lighting control service module, and a projection display service module; service interfaces and data models are designed to ensure loose coupling and high scalability between service modules; and in-vehicle networks, such as controller area network (CAN) and Ethernet, are integrated to achieve interconnection and interoperability with other vehicle systems.

[0100] Module Development: The environmental perception service module uses sensors such as cameras and radar to collect information about the vehicle's surrounding environment, providing data support for the lighting control service module and the projection display service module;

[0101] The user interaction service module develops the user interface and interaction logic for setting projection content and lighting control parameters.

[0102] The lighting control service module uses ambient environmental information and lighting control parameters to determine target lighting control parameters and automatically adjust parameters such as headlight brightness and illumination range.

[0103] The projection time-limited service module generates target projection content based on surrounding environmental information and projection content, projecting information such as emotional light messages, custom patterns, and text onto the road surface or vehicle body in front, achieving rich visual effects.

[0104] Integration testing: Integrate the various service modules to ensure they can communicate and exchange data normally; conduct comprehensive functional, performance, and security tests to verify the stability and reliability of the smart vehicle lighting system; and fix and optimize based on the test results to improve the user experience.

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

[0106] In summary, the proposed solution has the following beneficial effects:

[0107] (1) Enhance the versatility of functions: The headlights can not only be used for lighting, but also have a projection function, and can be used as a projection lamp, thus enhancing the versatility of the headlights.

[0108] (2) Enhance road safety: By projecting information such as distance reminders to vehicles ahead and weather warnings, the intelligent vehicle lighting system can provide drivers with key driving safety tips in real time, effectively reducing the risk of traffic accidents.

[0109] (3) Improve system scalability: Based on the SOA architecture, the intelligent vehicle lighting system is easy to expand and upgrade, and can quickly integrate new functions and services to adapt to the ever-changing needs of the automotive market.

[0110] (4) Enhance the driving experience: The headlights can project personalized patterns, expressions, text and other custom information, bringing drivers an unprecedented driving pleasure and personalized experience.

[0111] (5) Promote emotional communication: The intelligent vehicle lighting system expresses emotions by projecting target content, enabling vehicles to interact with the outside world emotionally, such as vehicle lighting parties and vehicle lighting concerts, which enhances the interaction between drivers, pedestrians, and other vehicles.
