The halogen headlamps have low brightness and low light-emitting efficiency, and in the night or under adverse weather conditions, the driver's field of view is limited, increasing the risk of driving safety. Although the xenon headlamps have high brightness, they have a long start-up time and perform poorly in some scenarios that require rapid response to lighting changes, and their energy consumption is large, which puts pressure on the vehicle battery.

[0039] Patent terms:

[0040] The intelligent high beam is a car safety device that realizes intelligent adjustment of the high beam through sensors and a control system, and the core technology is ADB (adaptive driving beam).

[0041] The projection lamp is a lamp that can project images, text or light effects onto a specific surface (such as a screen, wall, floor, etc.), mainly used in stage performances, film and television shooting, advertising displays, and business office scenes.

[0042] One embodiment of the present application provides a self-circulation high-pixel intelligent projection combined lighting control device and method for a car, to solve the problem that the existing car headlamp has poor compatibility, stability and safety. The self-circulation high-pixel intelligent projection combined lighting control device and method for a car focus on upgrading the traditional car headlamp to a high-pixel digital intelligent projection headlamp assembly (including but not limited to DLP, HD), which integrates self-circulation data acquisition-analysis-regulation mechanism and high-pixel digital projection technology, to realize intelligent, personalized and dynamic adaptation of car lighting.

[0043] Embodiment I:

[0044] One embodiment of the present application provides a self-circulation high-pixel intelligent projection combined lighting control device for a car. For example, please refer to Figure 1 , Figure 1 The frame diagram of the self-circulation high-pixel intelligent projection combined lighting control device for a car provided by one embodiment of the present application.

[0045] As shown in Figure 1 , the present application provides a self-circulation high-pixel intelligent projection combined lighting control device for a car, which includes a driving and data processing module 10, an intelligent lighting module 20 connected to the driving and data processing module 10, and a scene recognition and intelligent interaction module 30.

[0046] In the inventive embodiments of the application, the intelligent lighting module 20 integrates the car's low beam, signal light, high beam, projection lamp and camera equipment; the intelligent lighting module 20 is installed in the adaptive frame of the car, and the intelligent lighting module 20 is also used to collect image data in front of the car in real time through the camera equipment.

[0047] Further, the intelligent lighting device 20 includes a headlight assembly that still integrates an auxiliary low beam, an ADB adaptive high beam, a high-pixel digital projection lamp, and a signal lamp to enable the intelligent lighting device 20 to achieve high-pixel digital projection and ordinary lighting functions. In this embodiment, the intelligent lighting device 20 is installed at the position of the original headlight of the vehicle, ensuring that the field of view of the camera device covers the key area in front of the vehicle, while not affecting the lighting and projection functions of the headlight. The camera device can use a high-resolution, wide-angle CMOS image sensor, coupled with a high-performance optical lens. In another embodiment, the camera device can also use a common camera.

[0048] In this embodiment, the adaptive frame of the vehicle can be designed according to the existing vehicle headlight mounting space and fixing method, ensuring stable installation of the headlight assembly of the intelligent lighting device 20.

[0049] In this embodiment, the self-circulation high-pixel intelligent projection combined lighting control device of the vehicle directly acquires image data of the road information in front of the vehicle through the intelligent lighting device 20 that integrates the low beam, signal lamp, high beam, projection lamp, and camera device of the vehicle, greatly improving the real-time and accuracy of the data of the self-circulation high-pixel intelligent projection combined lighting control device of the vehicle, achieving more accurate high beam control, and improving night driving safety.

[0050] In one embodiment, the intelligent lighting device 20 selects a light source for the high-pixel digital intelligent projection headlight assembly. In addition to using an HD light source matrix, it can also try to use DLP projection technology. Laser projection can achieve higher resolution and color, and can bring more outstanding animation projection effects.

[0051] In the inventive embodiments of the application, the scene recognition and intelligent interaction module 30 is configured to acquire state information of the vehicle body and recognize the state information to obtain a driving scene of the vehicle, and output a projection signal for controlling the intelligent lighting module according to the driving scene.

[0052] Further, the scene recognition and intelligent interaction module 30 can be understood as acquiring the state information of the vehicle body in real time, automatically recognizing the current driving scene of the vehicle according to the state information, and outputting the projection signal of the control intelligent lighting module according to the real-time driving scene, so as to make the real-time data of the vehicle more intelligent and personalized, and to dynamically change the projection content according to the actual road conditions and driving scene of the vehicle, thereby enhancing the user driving experience and the high-pixel projection personalization. In this embodiment, the state information includes the door opening and closing state and the vehicle running state. The driving scene includes the welcome scene and the send-off scene. The self-circulation high-pixel intelligent projection combined lighting control device of the vehicle realizes the animation projection of the specific scene through the intelligent lighting module 20, such as the welcome and send-off modes, to bring a unique and personalized experience to the user, enhance the sense of technology and seniority of the vehicle, and improve the personalized interaction experience.

[0053] In one embodiment, the scene recognition and intelligent interaction module 30 can assist in scene judgment by exploring the use of artificial intelligence-based image recognition technology. By installing a camera device outside the vehicle, the image recognition algorithm is used to recognize the personnel and environmental changes around the vehicle, and the driving scene is more accurately judged. However, the image recognition algorithm has a high requirement for hardware computing power, and the accuracy and stability of the image recognition algorithm need to be further optimized.

[0054] In the inventive embodiment of the application, the driving and data processing module 10 is used for real-time analysis and processing of image data to obtain feature data, and controls the operation of the low beam, signal light, high beam and projection light according to the feature data and the projection signal, to realize scene animation projection.

[0055] Further, the driving and data processing module 10 is installed at a suitable position in the driver's cabin or engine compartment of the vehicle, which is convenient for heat dissipation and data transmission. The driving and data processing module 10 can be understood as controlling the operation of the low beam, signal light, high beam and projection light based on the projection signal of the scene recognition and intelligent interaction module 30 and the image data obtained by the intelligent lighting module 20 at the same time, to realize scene animation projection. In this embodiment, the driving and data processing module 10 is installed at a suitable position in the driver's cabin or engine compartment of the vehicle, which is convenient for heat dissipation and data transmission. The self-circulation high-pixel intelligent projection combined lighting control device of the vehicle realizes seamless docking with the original system of the vehicle through the driving and data processing module 10, ensures the compatibility and stability of the intelligent lighting module 20 and the vehicle electrical system and the driving and data processing module 30 after being equipped, and improves the compatibility of the self-circulation high-pixel intelligent projection combined lighting control device of the vehicle.

[0056] In addition, the Kalman filter algorithm is introduced to fuse the visual data of the camera (such as lane line deviation and obstacle distance) with the steering wheel angle, wheel speed and yaw rate provided by the vehicle CAN bus. By using the "self-circulation data collection-analysis-adjustment" mechanism, the lighting habits of the user in different road conditions are recorded, and the parameter weights of the control analysis unit are continuously optimized through edge computing. When the vehicle is driving on a curve, the fusion algorithm can predict the curve curvature earlier than pure visual recognition, intelligently control the adaptive front-lighting system (AFS) and the pre-judgment projection of high-pixel projection, and accurately illuminate the curve center blind area. With the increase of use time, the system can also realize dynamic adaptation according to the driving habits of the user, making the intelligent level of the headlamp continue to evolve.

[0057] The camera visual data is usually output at a frame rate of 30Hz or 60Hz, while the wheel speed and steering wheel angle signals on the CAN bus have significant differences in frequency. The algorithm needs to establish a high-precision global time reference, use linear interpolation or cubic spline interpolation method to map the high-frequency vehicle sensor data to the timestamp of the low-frame-rate visual image, and ensure that the vehicle state and environment are strictly synchronized at the moment of fusion calculation. When constructing the state vector, in addition to position and speed, the yaw rate should also be fused to construct the vehicle mass side slip angle estimation model, and the covariance matching technology is introduced to adjust the process noise matrix Q and observation noise matrix R online. When the visual data is affected by light and fluctuates, automatically increase the visual observation noise R to increase the trust weight of the vehicle body signal, and vice versa to enhance the correction ability of the vision to the lane curvature.

[0058] Since pure visual recognition is limited to the lane line curvature within the current field of view, the algorithm calculates the vehicle's transient steering radius and steady-state steering gain by fusing wheel speed and steering wheel angle, and constructs an extended Kalman filter (EKF) model to predict the virtual lane geometry outside the visual range (such as 50-100 meters). Based on the predicted virtual curve curvature and vehicle speed, the physical distance of the vehicle to the curve center is calculated, and the control algorithm dynamically calculates the horizontal deflection angle (Y-axis rotation) and vertical pitch angle (X-axis correction) of the headlamp module based on the Ackermann steering geometry, and compensates the beam pointing in advance when driving at high speed or merging on the ramp.

[0059] At the same time, the sliding window algorithm is used to extract and record the user's operation behavior in different scenarios (such as city with street lights, highway without street lights, rain and fog) in real time, and convert the tunnel light-on time, high beam opening time, and sudden turn speed reduction habit into structured logs with time stamp and scene label. Using the lightweight policy gradient method, the user's manual correction operation (such as dimming brightness, switching light type) is regarded as a reward signal, and the brightness response curve, adaptive front-lighting system sensitivity and other parameter weight matrices in the control analysis unit are adjusted accordingly.

[0060] In the application embodiment, the self-circulation high-pixel intelligent projection combined lighting control device of the automobile is improved in performance-price ratio and market competitiveness under the premise of ensuring the high-pixel digital projection headlamp lighting performance by the driving and data processing module 10, the intelligent lighting module 20 and the scene recognition and intelligent interaction module 30. The self-circulation high-pixel intelligent projection combined lighting control device of the automobile enriches the data source of the high-pixel personalized projection function through the intelligent lighting module 20 and the scene recognition and intelligent interaction module 30, so that the projection content can dynamically change according to the real-time road conditions, traffic signs, driving scenes and the like, and the user's personalized experience is improved. The self-circulation high-pixel intelligent projection combined lighting control device of the automobile simplifies the implementation process and reduces the implementation difficulty through the intelligent lighting module 20, so that the operation can be efficiently completed by professional personnel in the general automobile production or maintenance link, and the time and labor cost are reduced.

[0061] One embodiment of the present application provides a self-circulation high-pixel intelligent projection combined lighting control device of an automobile, which acquires image data of road information in front of the automobile in real time through an intelligent lighting module integrated with a low beam, a signal lamp, a high beam, a projection lamp and a camera device of the automobile, greatly improving the real-time performance and accuracy of data of the self-circulation high-pixel intelligent projection combined lighting control device of the automobile; the driving and data processing module and the scene recognition and intelligent interaction module are matched with each other to realize seamless connection of the original system of the automobile, ensuring the compatibility and stability of the automobile and solving the problem that the compatibility, stability and safety of the existing automobile headlamp are difficult to guarantee.

[0062] In the application embodiment, the intelligent lighting module 20 is sealingly arranged in the camera installation cabin corresponding to the adaptive frame; the intelligent lighting module 20 is wrapped with a protective shell; and / or the adaptive frame is arranged at the position of the headlamp of the automobile. The protective shell is externally provided with a heat dissipation device.

[0063] Further, the heat dissipation device can be selected as a heat dissipation fin. The multifunctional adapter and protection assembly is formed by the adapter frame and the protection shell, so that the intelligent lighting module 20 can be compatible with multiple vehicle models and easily installed in the high-pixel digital projection headlamp assembly. The self-circulation high-pixel intelligent projection combined lighting control device of the vehicle solves the adaptability problem of the vehicle equipped with the high-pixel digital projection headlamp through the intelligent lighting module 20, and also minimizes the modification to the original structure and electrical system of the vehicle, ensures that the safety and stability of the vehicle after being equipped are not affected, and ensures that the original vehicle state can be restored when necessary. In this embodiment, the camera device is integrated in the high-pixel digital intelligent projection headlamp assembly and is installed in the adapter frame of the multifunctional adapter and protection assembly and is fixed by buckles and bolts. The multifunctional adapter and protection assembly is installed at the original headlamp installation position of the vehicle. The driving and data processing module 10 is connected with the high-pixel digital intelligent projection headlamp assembly (such as the intelligent lighting module 20) integrated with the camera device, the vehicle sensors of the vehicle, the CAN bus, and the scene recognition and intelligent interaction module 30 through the wire harness.

[0064] In one embodiment, the protection shell is used to protect the camera device, and the protection shell is made of waterproof, dustproof and heat insulation materials, which provides a reliable protection environment for the camera device without affecting the optical performance of the camera device. The protection shell is provided with heat dissipation fins for heat dissipation of the camera device during work.

[0065] Further, the multifunctional adapter and protection assembly closely fits the vehicle headlamp installation structure, the protection shell wraps the camera device, and the heat dissipation fins are arranged at positions conducive to heat dissipation.

[0069] Further, the data acquisition unit 31 is connected with the vehicle through the CAN bus to acquire state information of the vehicle, such as door opening and closing state and vehicle running state.
