[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The vehicle lighting control method, system, storage medium, controller, and vehicle of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Figure 1 This is a flowchart of a vehicle lighting control method according to an embodiment of the present invention. Figure 1 As shown, vehicle lighting control methods may include: S101, select a target light effect workflow from the light effect workflow set according to the target light effect requirements, and control the vehicle's lighting module to generate the target light effect according to the target light effect workflow. The light effect workflow set includes at least one of preset light effect workflow, custom light effect workflow and shared light effect workflow.

[0029] To address the issue that vehicle lighting systems are too limited in function and cannot meet the personalized needs of users in the era of intelligent technology, this invention allows for the selection of a target lighting effect workflow from a set of lighting effect workflows, including preset lighting effect workflows, custom lighting effect workflows, and / or shared lighting effect workflows, based on the desired lighting effect requirements. The invention then controls the vehicle's lighting modules to produce the corresponding lighting effect according to the selected target lighting effect workflow.

[0030] The target lighting effect requirements in this embodiment of the invention may include user requirements and vehicle current scene requirements, etc.

[0031] Specifically, a target lighting effect workflow can be selected from the lighting effect workflow set based on user needs. Alternatively, a target lighting effect workflow can be selected from the lighting effect workflow set based on the current scenario requirements of the vehicle.

[0032] Implementably, a lighting effect workflow management module can be set up to manage lighting effect workflows in a centralized collection, enabling functions such as selecting, downloading, and uploading lighting effect workflows. The lighting effect workflow selection function specifies which lighting effect workflow is currently in use. Users can choose a target lighting effect workflow based on personal preference or different workflows depending on the usage scenario. The target lighting effect workflow can be determined by reading the lighting effect workflow currently selected by the user from the centralized collection.

[0033] In practice, the current scene in which the vehicle is located can be monitored, and the target light effect workflow corresponding to the current scene can be determined according to a preset scene-light effect workflow. For example, when a preset vehicle unlock-dynamic water surface interaction light effect workflow is available, after detecting that the vehicle is unlocked, the target light effect workflow can be determined to be the dynamic water surface interaction light effect workflow, and the vehicle's lighting module can be controlled to generate the target light effect according to the dynamic water surface interaction light effect workflow.

[0034] The vehicle's lighting modules are controlled according to the defined target lighting effect workflow to produce the target lighting effect and achieve personalized lighting requirements.

[0035] The vehicle lighting control method in this embodiment of the invention can select a target lighting effect workflow from a set of lighting effect workflows, including preset lighting effect workflows, custom lighting effect workflows, and shared lighting effect workflows, according to the target lighting effect requirements. It can also control the vehicle's lighting module to generate the target lighting effect according to the selected target lighting effect workflow, thereby realizing the user-created personalized lighting effect and solving the problem of monotonous vehicle lighting effects.

[0036] In one embodiment of the present invention, the custom lighting effect workflow includes at least one of the following: Light effect workflow generated based on user input information; A workflow for generating light effects based on input information obtained through an interactive interface; A workflow for generating light effects based on input information obtained through a programming interface.

[0037] In this embodiment of the invention, the user's input information includes, but is not limited to, natural language and image messages. Specifically, the user can describe their needs to the AI ​​agent using natural language, and the AI ​​agent will automatically parse the user's lighting control requirements and generate a corresponding lighting effect control workflow.

[0038] In practice, users can customize the light effect control logic (input information) through a visual interactive interface to generate the corresponding light effect workflow.

[0039] In practice, developers can customize the light effect control logic (input information) through a programming interface to generate the corresponding light effect workflow.

[0040] It should be noted that developers can also create corresponding lighting effect workflows using AI agents or interactive interfaces. The AI ​​Agent can be fine-tuned using the Qwen3-Coder code model.

[0041] The vehicle lighting control method in this embodiment of the invention supports two user creation modes: developer creation mode and ordinary user creation mode. By constructing a light effect workflow, the user's needs are directly converted into control commands for the lighting module, realizing personalized configuration of the vehicle lighting control system and solving the problem that traditional chassis lighting control systems do not support user customization and lack personalized experience.

[0042] In one embodiment of the present invention, the preset lighting effect workflow may include at least one of the following: a welcoming lighting effect workflow, a farewell lighting effect workflow, a holiday-themed lighting effect workflow, a driving safety lighting effect workflow, and a dynamic interactive lighting effect workflow.

[0043] Among them, the welcome light effect workflow can project a welcome pattern through the vehicle projector when passengers get on the vehicle, and can simultaneously activate the LED light bar and LED lights for supplementary lighting at night. The sending-off light effect workflow can project a goodbye pattern through the vehicle projector when passengers get off the vehicle, and can simultaneously activate the LED light bar and LED lights for supplementary lighting at night. The festival theme light effect workflow automatically activates the festival-exclusive light effect according to the calendar system. The driving safety light effect workflow can automatically activate the LED warning light strip based on the environmental perception system (fog / rain / night). The dynamic water surface interaction light effect workflow can parse the passenger position data through sensor data, generate a water ripple effect in the pattern projected by the welcome light, and realize the linkage between the welcome light projection and body movements.

[0044] In an embodiment of the present invention, the shared light effect workflow includes the light effect workflow obtained from the light effect sharing platform.

[0045] In an embodiment of the present invention, the shared light effect workflow includes the light effect workflow uploaded by the user to the light effect sharing platform.

[0046] In an embodiment of the present invention, the shared light effect workflow includes the light effect workflow that can be downloaded from the light effect sharing platform and the light effect workflow uploaded by the user to the light effect sharing platform.

[0047] Implementably, the light effect workflow management module can also provide the light effect sharing platform function, supporting the upload and download of user light effects. Specifically, the user can upload the light effect workflow (custom light effect workflow) created by them to the light effect sharing platform. When there are custom light effect workflows uploaded by other users on the light effect sharing platform, the user can obtain the light effect workflow from the light effect sharing platform. For example, the user can download the light effect workflow uploaded by other users, and the light effect workflow downloaded to the local light effect workflow set is the shared light effect workflow.

[0048] In each embodiment of the present invention, each light effect workflow corresponds to a corresponding configuration file. After determining the target light effect workflow, the configuration file corresponding to the target light effect workflow can be loaded, and the lighting module of the vehicle can be controlled according to the configuration file corresponding to the target light effect workflow to generate the target light effect.

[0049] In an embodiment of the present invention, controlling the lighting module of the vehicle to generate the target light effect according to the target light effect workflow may include: Generating a light effect signal according to the target light effect workflow and target data, and controlling the lighting module to generate the target light effect according to the light effect signal; or, Generating a light effect digital signal according to the target light effect workflow and target data, and controlling the lighting module to generate the target light effect according to the light effect digital signal; or, Generating a light effect control signal according to the target light effect workflow and target data, and controlling the lighting module to generate the target light effect according to the light effect control signal; or, According to the target lighting effect workflow, the target service interface and target model are called to process the target data, generate a digital lighting effect signal, and control the lighting module to produce the target lighting effect based on the digital lighting effect signal; or, Based on the target lighting effect workflow, the target service interface and target model are called to process the target data, generate a lighting effect digital signal, convert the lighting effect digital signal into a lighting effect control signal, and control the lighting module to produce the target lighting effect according to the lighting effect control signal.

[0050] Specifically, after determining the target lighting effect workflow, the configuration file corresponding to the target lighting effect workflow is loaded, and the target data required to achieve the corresponding lighting effect can be determined from the configuration file corresponding to the target lighting effect workflow.

[0051] In practice, a light effect signal is generated based on the target light effect workflow and target data, and the light module is controlled to produce the target light effect based on the light effect signal. For example, when the target light effect workflow is selected as the driving safety light effect workflow, the target data is the target data itself. Environmental data collected by onboard sensors can be obtained according to the configuration file corresponding to the driving safety light effect workflow. When the environmental data determines that the current environment is fog / rain / nighttime, the LED warning light strip is activated.

[0052] In practice, a light effect digital signal is generated based on the target light effect workflow and target data, and the light module is controlled to produce the target light effect based on the light effect digital signal. For example, when the target light effect workflow is selected as a holiday-themed light effect workflow, the target data is calendar data. The calendar data can be obtained from the configuration file corresponding to the holiday-themed light effect workflow. When the current calendar is determined to be the corresponding holiday based on the calendar data, a holiday-specific light effect digital signal, such as an LED driver digital signal, is generated to control the light module to produce the target light effect.

[0053] In practice, a light effect control signal is generated based on the target light effect workflow and target data, and the lighting module is controlled to produce the target light effect according to the light effect control signal. For example, the target light effect workflow is selected as either a welcome light effect workflow or a farewell light effect workflow, and the target data is vehicle speed information and door information. The vehicle speed information and door information can be obtained from the corresponding configuration file of the welcome light effect workflow or the farewell light effect workflow. When it is determined that the vehicle is stationary and the door is open, a welcome pattern light effect control signal or a goodbye pattern light effect control signal is generated. Based on the welcome pattern light effect control signal or the goodbye pattern light effect control signal, the vehicle projector is controlled to project a welcome pattern or a goodbye pattern at the corresponding door position.

[0054] For implementation details, see [link to relevant documentation]. Figure 2The system loads the configuration file corresponding to the target lighting effect workflow. From this file, the target data, target service interfaces, and target models required to achieve the desired lighting effect can be determined. Therefore, the target data can be processed by calling the target service interfaces and target models according to the configuration file, generating digital lighting effect signals, such as digital projection image signals and / or LED driver signals. Based on these digital lighting effect signals, such as LED driver signals, the lighting module is controlled to produce the target lighting effect. Alternatively, the digital lighting effect signals, such as digital projection image signals, can be converted into lighting effect control signals executable by the lighting module, and these converted control signals are sent to the lighting module to control it to produce the target lighting effect.

[0055] The embodiments of the present invention employ a model context protocol to provide standardized service interfaces and context interaction rules for the target model for the target light effect workflow.

[0056] Specifically, the Model Context Protocol (MTP) is adopted to provide standardized service interfaces and context interaction rules for the target model in the target lighting effect workflow. This ensures that the model can accurately receive historical interaction information and real-time scene data, maintaining the logical continuity of task execution. At the same time, it standardizes the collaborative process between the model and service interfaces, tool modules, and hardware units, and clarifies the boundaries of data flow and permission division. This avoids model misunderstanding or decision-making errors caused by chaotic context formats, achieves efficient integration of model capabilities with actual business processes, and improves the stability, scalability, and security compliance of lighting effect control.

[0057] The target models in this embodiment of the invention include, but are not limited to, server-based deep learning large models, edge computing-based lightweight task-specific model services, and task-specific interfaces (open APIs to third-party developers, allowing them to create their own models and interfaces).

[0058] Server-based deep learning large models, such as multimodal large language models running on servers (DeepSeek-V3, Gemini-2.5-flash-image, etc.), receive multimodal data from the vehicle's infotainment system and return the model's output.

[0059] Lightweight task-specific models based on edge computing, running on in-vehicle edge computing platforms (cockpit domain controllers), such as road pothole detection models (e.g., POT-YOLOv8) and 3D human posture detection models (e.g., RTMW, SMPL).

[0060] Task-specific interfaces (function interfaces specifically configured to complete a certain task), such as: location information interface, which receives data from ultrasonic radar and returns the relative positions of various objects and vehicles; time interface, which obtains the current time, etc.

[0061] In one embodiment of the present invention, the target data includes at least one of vehicle status data, calendar data, and environmental data.

[0062] As a specific example, when the target lighting effect workflow is selected as the welcome lighting effect workflow or the farewell lighting effect workflow, the vehicle speed information and door information can be obtained. When the vehicle is stationary and the door is open, a welcome pattern or a goodbye pattern is projected onto the corresponding door position through the vehicle projector.

[0063] As a specific example, when the target lighting effect workflow is selected as the holiday-themed lighting effect workflow, calendar data is obtained, and when the current holiday is determined based on the calendar data, the holiday-specific lighting effect is generated.

[0064] As a specific example, if the target lighting effect workflow is selected as the driving safety lighting effect workflow, then the environmental data collected by the vehicle's sensors will be acquired, and the LED warning light strip will be automatically activated in fog / rain / nighttime.

[0065] It should be noted that the embodiments of the present invention do not limit the target data, and the target data can be determined according to the target light effect workflow.

[0066] In one embodiment of the present invention, the vehicle lighting control method may further include: If the target data includes environmental data, the environmental data is preprocessed before the vehicle's lighting module generates the target lighting effect according to the target lighting effect workflow.

[0067] Specifically, when the target data includes environmental data, the environmental data is preprocessed before the vehicle's lighting module generates the target lighting effect according to the target lighting effect workflow, and the environmental data is generated into a standardized data packet.

[0068] In one embodiment of the present invention, the environmental data may include at least one of visual data, ambient light data, ultrasonic radar data, distance data, positioning data, lidar data, millimeter-wave radar data, and acoustic data.

[0069] In practical terms, visual perception can be achieved using an onboard high-resolution camera (supporting wide-angle coverage and real-time acquisition of images of the vehicle's surrounding environment, including road conditions and passenger information inside and outside the vehicle) to collect visual data about the vehicle's surroundings. Environmental perception can be achieved using an onboard ambient light sensor (real-time monitoring of light intensity, supporting dynamic image gain adjustment) to collect ambient light data about the vehicle's surroundings. Spatial perception can be achieved using onboard ultrasonic radar (0.1-5 meter short-range ranging, obstacle positioning accuracy ±3cm), lidar (precisely constructing a 3D point cloud map, achieving high-precision detection of the distance, position, shape, and speed of obstacles), and / or millimeter-wave radar to collect ultrasonic radar data, lidar data, and / or millimeter-wave radar data about the vehicle's surroundings. Acoustic perception can be achieved using an onboard intelligent voice array (microphone beamforming, supporting noise reduction and voice localization) to collect acoustic data about the vehicle's surroundings.

[0070] In one embodiment of the present invention, preprocessing of environmental data may include: The environmental data is denoised, and the denoised environmental data is then aligned in time and space.

[0071] Specifically, when the target light effect workflow determines that one or more environmental data from among visual data, ambient light data, ultrasonic radar data, distance data, positioning data, lidar data, millimeter-wave radar data, and acoustic data are needed, the corresponding sensors are triggered or triggered in parallel to collect relevant data and establish a global time reference. Denoising algorithms, such as sliding window filtering and Kalman filtering, are used to denoise the data collected by the corresponding sensors (removing noisy data). Then, the denoised data undergoes time alignment (multi-sensor data synchronization) and spatial alignment processing to generate standardized data packets (including timestamps, spatial coordinate systems, etc.).

[0072] In one embodiment of the present invention, the lighting module may include a projector, and the target lighting effect is a target image projected by the projector, the target image being generated based on the target lighting effect workflow.

[0073] The vehicle lighting module in this embodiment of the invention may include a projector (such as a DLP (Digital Light Processing) projector), LED lights and LED strips, as well as other related driveable lighting devices.

[0074] In one embodiment of the present invention, the light effect digital signal may include the projection image digital signal and the LED driving digital signal.

[0075] Specifically, the light effect digital signal may include the projected image digital signal and the LED driver digital signal, as well as the digital signals corresponding to other related lighting equipment.

[0076] In one embodiment of the present invention, the lighting module may include a projector, and the light effect digital signal may include a projected image digital signal. Converting the light effect digital signal into a light effect control signal may include: The digital signal of the projected image is decoded and converted into a DMD micromirror control signal.

[0077] Specifically, the generated digital signal of the projected image is decoded, and the decoded data is optimized by techniques such as color correction, brightness adjustment, and geometric correction to generate pixel data. Then, the pixel data is converted into DMD (Digital Micro mirror Device) micromirror control signals to drive the projector to produce the corresponding projected image.

[0078] In one embodiment of the present invention, the lighting module may include LED lights and LED strips, and the luminous efficacy digital signal may include an LED driving digital signal. Converting the luminous efficacy digital signal into a luminous efficacy control signal includes: Convert the LED driver digital signal into a PWM control signal.

[0079] Specifically, the generated LED driving digital signal is converted into a PWM (Pulse Width Modulation) control signal to drive the LED lamps and / or LED strips to produce the corresponding target light effect.

[0080] It should be noted that the luminous effect digital signal may include only the luminous effect control signal, or only the LED driver digital signal, or it may include both the luminous effect control signal and the LED driver digital signal.

[0081] It should be noted that the embodiments of the present invention do not limit the lighting devices included in the vehicle lighting module, and may also include lighting devices other than projectors, LED lights, and LED light strips. When controlling the relevant lighting devices to produce the target light effect, the light effect digital signal is converted into a control signal that can drive the lighting device.

[0082] In one embodiment of the present invention, the vehicle lighting control method may further include: The hardware information fed back by the lighting module is monitored in real time, and hardware protection operations are performed based on the hardware information, wherein the hardware information includes at least one of temperature, voltage and power consumption; and / or, the hardware protection operations include at least one of generating abnormal prompt information and reducing the brightness of the corresponding lighting module.

[0083] In one specific embodiment, the hardware information may include hardware information such as temperature, voltage, and power consumption of the projector, LED lights, and LED light strips.

[0084] Specifically, it receives hardware information such as temperature, voltage, and power consumption from the projector, LED lights, and LED light strips, and monitors this information in real time. When abnormal hardware information is detected, a graphical interface can be used to generate a prompt message to alert the user to the corresponding hardware malfunction. It can also provide corresponding hardware protection measures, such as reducing the brightness of the corresponding light module.

[0085] In one embodiment of the present invention, when the target light effect workflow is a dynamic interactive light effect workflow, the target data includes a light effect image and target position data. Generating a light effect signal based on the target light effect workflow and the target data, and controlling the lighting module to generate the target light effect based on the light effect signal, includes: determining the location information of key points on a pedestrian's feet based on the target position data; generating a dynamic interactive light effect signal based on the light effect image and the location information of key points on a pedestrian's feet; and controlling the lighting module to generate the dynamic interactive light effect based on the dynamic interactive light effect signal.

[0086] In one embodiment of the present invention, the target location data includes object coordinate point information within a preset range of the vehicle and pedestrian limb key point location information. The object coordinate point information is obtained by ultrasonic radar, and the pedestrian limb key point location information is obtained based on image data.

[0087] In one embodiment of the present invention, the key point location information of the pedestrian's feet is obtained by point cloud extraction processing of target location data, wherein the target location data is obtained by lidar.

[0088] The following description uses a dynamic interactive light effect workflow, specifically a dynamic water surface interactive light effect workflow, as an example to illustrate a specific embodiment of the present invention. Figure 3 As shown, when the dynamic interactive lighting effect workflow is a dynamic water surface interactive lighting effect workflow, the target data may include water surface images, ultrasonic radar data, and image data. The target service interface includes a ripple interface, a location information interface, and a human pose estimation model interface. The target model may include a human pose estimation model. According to the target lighting effect workflow, the target service interface and target model are called to process the target data and generate a lighting effect digital signal, which may include: S201, call the location information interface to process the ultrasonic radar data to obtain the coordinate point information of the object within the preset range of the vehicle. At the same time, call the human posture estimation model interface to process the image data using the human posture estimation model to obtain the location information of the key points of the pedestrian's limbs. S202, Determine the location information of the key points of the pedestrian's feet based on the object's coordinate point information and the location information of the key points of the pedestrian's limbs; S203 calls the ripple interface to generate a dynamic water surface interactive light effect digital signal based on the water surface image and the key point position information of the pedestrian's feet.

[0089] Specifically, when the vehicle is a low-end model and the target light effect workflow is a dynamic water surface interactive light effect workflow, the dynamic water surface interactive light effect workflow based on low-end and mid-range models triggers ultrasonic radar and fisheye camera to collect relevant environmental data in parallel.

[0090] After unlocking a mid-to-low-end vehicle, the lighting effects software automatically starts, loading the dynamic water surface interactive lighting effects workflow corresponding to that vehicle model. It triggers the ultrasonic radar and fisheye camera to collect relevant data. The data collected by the millimeter-wave radar is denoised using a particle filter algorithm, and the images collected by the fisheye camera are denoised using an adaptive median filter algorithm. The denoised data is then aligned in time and space and packaged into a standard data package.

[0091] Based on the dynamic water surface interactive lighting effect workflow corresponding to mid-to-low-end vehicle models, the location information interface API (Application Programming interface) and the 2D human pose estimation model API are called respectively. The location information interface API receives ultrasonic radar data and returns the distance information between the vehicle and the objects around the vehicle. The 2D human pose estimation model API (the 2D human pose estimation model uses the RTM Pose model) receives image data captured by a fisheye camera and returns the location information of key points of pedestrian limbs in the image.

[0092] The coordinate information (distance information between the vehicle and objects around the vehicle) returned by the location information API is matched with the pedestrian center key point information (pedestrian limb key point location information) returned by the 2D human pose estimation model API. The coordinate information returned by the location information API is used to correct the pedestrian center key point information returned by the 2D human pose estimation model API to obtain accurate pedestrian footstep key point location information.

[0093] The Ripple Interface API is invoked. It receives a projected image of the original dynamic water surface (or a frame from a video of the original dynamic water surface) and key location information of pedestrian footsteps. The simulated water level is calculated by iteratively solving the wave equation. This simulated water level is then used to adjust the brightness of the corresponding location in the projected image; higher water levels result in greater brightness, and lower water levels in less brightness. The Ripple Interface API returns a projected image of the dynamic water surface interaction (a digital signal of the dynamic water surface interaction lighting effects).

[0094] The projected image of dynamic water surface interaction is decoded using decoding software and converted into a DMD micromirror control signal. The DMD micromirror control signal is then sent to the projector to drive the projector to generate dynamic water surface interaction light effects.

[0095] In one specific embodiment of the present invention, such as Figure 4As shown, when the dynamic interactive lighting effect workflow is a dynamic water surface interactive lighting effect workflow, the target data may include water surface images and LiDAR data, the target service interface may include a ripple interface and a human point cloud extraction interface, and the target model may include a human point cloud extraction model. According to the target lighting effect workflow, the target service interface and target model are called to process the target data and generate a lighting effect digital signal, which may include: S301, call the human body point cloud extraction interface, use the human body point cloud extraction model to process the LiDAR data, and obtain the location information of key points of the pedestrian's feet. S302 calls the ripple interface to generate a dynamic water surface interactive light effect digital signal based on the water surface image and the key point position information of pedestrians' feet.

[0096] Specifically, when the vehicle is a high-end model and the target light effect workflow is a dynamic water surface interactive light effect workflow, the dynamic water surface interactive light effect workflow based on the high-end model triggers the lidar camera to collect relevant multimodal environmental data.

[0097] After the high-end vehicle is unlocked, the lighting effects software automatically starts, loading the dynamic water surface interactive lighting effects workflow corresponding to the high-end model. This triggers the LiDAR to collect relevant data. The LiDAR-collected data is then denoised using the DBSCAN clustering algorithm. The denoised data is then aligned temporally and spatially and packaged into a standard data packet.

[0098] Following the workflow of dynamic water surface interactive lighting effects corresponding to high-end models, the human body point cloud extraction API is called to receive LiDAR data, the human body point cloud extraction model is used to process the LiDAR data, and the human body foot position information is returned.

[0099] The Ripple Interface API is invoked. It receives a projected image of the original dynamic water surface (or a frame from a video of the original dynamic water surface) and key location information of pedestrian footsteps. The simulated water level is calculated by iteratively solving the wave equation. This simulated water level is then used to adjust the brightness of the corresponding location in the projected image; higher water levels result in greater brightness, and lower water levels in less brightness. The Ripple Interface API returns a projected image of the dynamic water surface interaction (a digital signal of the dynamic water surface interaction lighting effects).

[0100] The projected image of dynamic water surface interaction is decoded using decoding software and converted into a DMD micromirror control signal. The DMD micromirror control signal is then sent to the projector to drive the projector to generate dynamic water surface interaction light effects.

[0101] The embodiments of the present invention include two workflows for implementing dynamic water surface interactive light effects, see [link to documentation]. Figure 5The dynamic water surface interactive lighting effect workflow for low-to-mid-range models is for vehicles without LiDAR, while the dynamic water surface interactive lighting effect workflow for high-end models is for vehicles equipped with LiDAR.

[0102] The vehicle lighting control method of this invention provides a lighting effect workflow that supports dual user creation modes. Based on the selected target lighting effect workflow, it can control the vehicle chassis lighting module to generate the target lighting effect. The MCP protocol is used to construct a standardized service interface for the target lighting effect workflow.

[0103] This invention provides a vehicle lighting control system.

[0104] Figure 6 This is a schematic diagram of a vehicle lighting control system according to an embodiment of the present invention. Figure 6 As shown, the vehicle lighting control system 100 may include: The light effect control module 10 is used to select a target light effect workflow from the light effect workflow set according to the target light effect requirements, and control the vehicle's lighting module to generate the target light effect according to the target light effect workflow. The light effect workflow set includes at least one of preset light effect workflow, custom light effect workflow and shared light effect workflow.

[0105] Specifically, such as Figure 7 As shown, the light effect control module 10 adopts a ternary architecture design, consisting of a software unit, a storage unit, and a communication unit. The software unit, serving as the system's central hub, comprises three main functional components: light effect software, model service software, and driver software.

[0106] The software module provides the core functions of the entire light effect control module 10 through light effect software, model service software, and driver software: creation, management, and execution of light effect workflows; provision of model services and tools; and conversion of light effect digital signals into hardware control signals.

[0107] The lighting effects software revolves around three main services: generation, management, and execution of lighting effects workflows. It provides four main functions: graphical interaction, lighting effects workflow management, lighting effects workflow generation, and lighting effects command generation. (See also...) Figure 6 : The graphical interface provides users with a multi-terminal graphical interface (mobile APP / vehicle APP). Users can create lighting effect workflows, determine tool modules and data flow, and export configuration files for the lighting effect workflows through the graphical interface. Lighting effect workflow management helps users manage lighting effect workflows, enabling functions such as selecting, downloading, and uploading lighting effect workflows. The lighting effect workflow selection function specifies which lighting effect workflow is currently in use. Users can also select different lighting effect workflows based on usage scenarios, such as using a driving safety lighting effect workflow when the vehicle is in motion, and a welcome / farewell lighting effect workflow when the vehicle is parked. Lighting effect workflow management provides a lighting effect sharing platform function, supporting the uploading and downloading of user-created lighting effect workflows. Users can upload their own created lighting effect workflows and download those uploaded by other users. Lighting effect workflow generation supports dual user interaction modes. Developers can customize lighting effect control logic through a programming interface to generate lighting effect control workflows. Ordinary users can describe their needs to the AI ​​Agent through natural language interaction, and the AI ​​Agent will automatically parse and generate the corresponding lighting effect control workflow. Ordinary users can also create lighting effect workflows through a graphical interface. The lighting effect command is generated by reading the target lighting effect workflow currently selected by the user, calling the target model and tool (service) interface, and generating digital signals for the projected image and LED driving.

[0108] In this embodiment of the invention, the model service software provides the lighting effect software with server-based deep learning large models, edge computing-based lightweight task-specific model services, and specific task interfaces (open APIs to third-party developers, allowing them to create their own models and interfaces) through the MCP protocol. Server-based deep learning models, including multimodal language models such as DeepSeek-V3 and Gemini-2.5-flash-image, run on servers and receive multimodal data from the vehicle's infotainment system, returning the model's output. Lightweight task-specific models based on edge computing, running on in-vehicle edge computing platforms (cockpit domain controllers), such as road surface pothole detection models (e.g., POT-YOLOv8) and 3D human pose detection models (e.g., RTMW, SMPL). Specific task interfaces: function interfaces specifically configured to complete a particular task, such as location information interfaces that receive data from ultrasonic radar and return the relative positions of objects and the vehicle; and time interfaces that retrieve the current time.

[0109] In this embodiment of the invention, the driver software provides two main functions: signal conversion and hardware monitoring. Signal conversion: It receives the digital signal of the projected image and the LED drive signal generated by the lighting effect software, decodes the digital signal of the projected image, and converts it into a DMD micromirror control signal; it also converts the LED drive digital signal into a PWM control signal. Hardware monitoring: It receives hardware information from the lighting module and monitors in real time the health information of various hardware devices in the chassis lighting system, such as the miniature DLP laser projector, LED strips, and LED lights, including data such as temperature, voltage, and power consumption. Devices with abnormal data are alerted to the user through a graphical interface, and hardware protection functions are provided (e.g., automatically reducing the brightness of a hardware component when its temperature is too high).

[0110] In this embodiment of the invention, the storage unit includes storage hardware DRAM (Dynamic Random Access Memory), SRAM (Static Random Access Memory), SDD (Solid State Drive), and FMS (File Management System), mainly providing storage and management services for various types of data, and realizing functions such as data reading, writing, organization, management, and reliability assurance.

[0111] The first communication unit transmits data with the environmental sensing module and the lighting module via the CNA / LIN bus communication protocol.

[0112] The vehicle lighting control system 100 in this embodiment of the invention may further include a lighting module.

[0113] Specifically, such as Figure 8 As shown, the lighting module includes lighting equipment, a control unit, and a second communication unit.

[0114] The lighting equipment includes various hardware devices in the lighting system, such as power adapters, DLP projectors, LED lights, LED strips, and other related driveable hardware devices. The control module is responsible for distributing the light effect control signals from the light effect control module 10 to the corresponding lighting devices and collecting feedback information from the hardware and sending it back to the light effect control module 10. The second communication module uses the CAN / LIN bus communication protocol to transmit data with the light effect control module 10.

[0115] The vehicle lighting control system 100 in this embodiment of the invention may further include an environmental perception module.

[0116] Specifically, such as Figure 9 As shown, the environmental perception module S02 includes on-board sensors, a data processing unit, and a third communication unit.

[0117] The vehicle-mounted sensors are used to collect multimodal environmental data. These sensors include, but are not limited to, high-resolution cameras, ambient light sensors, ultrasonic radar, lidar, and intelligent voice arrays for visual, environmental, spatial, and acoustic perception. The data processing unit preprocesses the multimodal environmental data, performing data cleaning (removing noise) and spatiotemporal alignment (synchronizing multi-sensor data), generating standardized data packets (including timestamps and spatial coordinate systems). The third communication unit establishes a communication channel with the light effect control module 10 via the CAN / LIN bus protocol.

[0118] The lighting efficiency workflow of the environmental perception module is as follows: In the data acquisition phase, each sensor is triggered in parallel to acquire data, and a global time reference is established. In the data processing phase, denoising algorithms (such as sliding window filtering and Kalman filtering) are used to denoise the data collected by the sensors. The collected data is then aligned in time and space, and standardized data packets are generated. In the data transmission phase, standard data packets are transmitted to the intelligent software system via the CAN / LIN bus communication protocol.

[0119] It should be noted that other specific embodiments of the vehicle lighting control system provided in the embodiments of the present invention can be found in other specific embodiments of the vehicle lighting control method of the above embodiments of the present invention.

[0120] The vehicle lighting control system of this invention constructs a standardized service interface through the MCP protocol. The system adopts a layered and decoupled three-tier architecture of "perception-decision-execution" and supports dual user interaction modes. This architecture enables independent development and deployment of functional components through modular design, provides standardized communication interfaces at the protocol layer to support multi-device collaboration, and ultimately achieves personalized lighting presentation to meet user needs through the collaborative control of the three-tier architecture. The system as a whole possesses good scalability and scene adaptability.

[0121] The environmental perception module in this embodiment of the invention identifies environmental information (such as weather, light intensity, road surface information, etc.) and characteristics of passengers (such as location, photos, etc.) near the vehicle through on-board multi-source sensors (including but not limited to ambient light sensors, cameras, ultrasonic radar, etc.).

[0122] The lighting effect control module, through a graphical app (mobile phone / vehicle infotainment system), provides services to users focusing on three main functions: generating, managing, and executing lighting effect workflows. It includes commonly used lighting effect workflows, which users can directly select or implement through programming, AI agents, or an interactive interface to create complex workflows. Users can also download lighting effect workflows created by others from the community marketplace. Based on the selected workflow, the lighting effect control module retrieves the corresponding models and service interfaces to process the data and generate digital lighting effect signals. The model service software provides various model and tool interfaces (service interfaces) to the lighting effect software via the MCP protocol. The driver software receives the digital lighting effect signals generated by the lighting effect software and converts them into hardware-recognizable lighting effect control signals.

[0123] The control unit of the lighting module adopts a high-precision PWM drive circuit, which receives the light effect control signal from the light effect control module, drives the chassis LED lights, LED light strips and the undercarriage projector to generate dynamic light effects and realize real-time lighting control response.

[0124] It should be noted that traditional chassis lighting control systems have three major technical limitations: First, they adopt a closed architecture design, with control logic fixed in preset static code, lacking dynamic configuration capabilities; second, the system is deeply coupled with specific hardware platforms, requiring a complete code reconstruction when the ECU architecture or communication protocol of the target vehicle is incompatible, leading to a significant increase in deployment and migration costs; finally, due to the lack of standardized interfaces and protocol adaptation mechanisms, the system cannot meet the access requirements of new hardware platforms through modular upgrades, severely restricting cross-vehicle platform expansion applications.

[0125] Compared to traditional vehicle lighting control systems, the vehicle lighting control system of this invention implements a three-layered architecture based on "perception-decision-execution," combined with the MCP communication protocol, to construct a modular vehicle lighting control system. This architecture, through layered decoupling, enables independent development and deployment of functional modules. The system as a whole possesses excellent scalability and maintainability, and can adapt to different vehicle models and chassis lighting control requirements.

[0126] It should be noted that the vehicle lighting control system of this invention supports the flexible deployment of multiple control schemes through modular design and standardized MCP protocol interface; at the same time, when there are compatibility limitations of the target vehicle hardware platform, the lighting effect workflow and interface generation adaptation alternatives can be dynamically adjusted; for the access of new hardware, the corresponding system module interfaces can also be updated remotely via OTA.

[0127] The vehicle lighting control system of this invention supports two user creation modes: developers can customize the lighting control logic through a programming interface, while ordinary users can describe their needs to an AI Agent through natural language interaction. The AI ​​Agent will automatically parse and generate the corresponding lighting effect control workflow. By constructing a lighting effect workflow, user needs are directly transformed into control commands, realizing personalized configuration of the lighting control system.
