Description

Technical Field

[0001] This invention relates to the field of vehicle control, and specifically to a control method, device, equipment, and vehicle for a sun visor display screen. Background Technology

[0002] With the rapid development of intelligent and connected vehicles, the interaction needs between vehicles and their surrounding environment and people are becoming increasingly diversified. As an important information interaction carrier, the application scenarios of vehicle exterior displays are constantly expanding. In existing technologies, vehicle exterior displays are mostly set in fixed positions such as the side or rear of the vehicle body. Functionally, they are mostly based on independent display or only display fixed brand logos, warning signs, etc., lacking the flexibility to dynamically adapt to different scenarios.

[0003] While some advanced solutions can achieve simple information display updates, they are not specifically designed for the differentiated scenarios on the left and right sides of the vehicle, and cannot accurately capture the different interaction needs occurring simultaneously on both sides. Furthermore, most existing external displays lack the ability to adjust the displayed content according to different scenarios, resulting in insufficient accuracy and effectiveness in information transmission, making it difficult to meet the efficient interaction needs of vehicles and various types of people in complex traffic environments. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a control method, device, equipment, and vehicle for a sun visor display screen, in order to solve the problem that the prior art cannot dynamically adapt to and collaboratively display information for different scenarios on the left and right sides of a vehicle.

[0005] In a first aspect, embodiments of the present invention provide a control method for a sunshade display screen, the method comprising: Acquire real-time scene images of the lateral range corresponding to each sun visor in the vehicle; Analyze the real-time scene images of each lateral range to obtain the interactive correlation features in the real-time scene information; Based on the aforementioned interactive association features, collaborative planning is performed to obtain the linkage strategy and the scene response information corresponding to each sunshade. According to the linkage strategy, the corresponding sun visor in the vehicle is controlled to flip outward so as to display the corresponding scene response information on the display screen set on the outside of the sun visor.

[0006] Furthermore, the analysis of real-time scene images in each lateral range to obtain interaction-related features in the real-time scene information includes: Identify target objects in real-time scene images of each lateral range that have interaction needs with the vehicle; The target object is tracked and identified to obtain the key features of the target object and the relative dynamic features of the target object and the vehicle. The interaction association features are constructed based on the key features of the object and the relative dynamic features.

[0007] Furthermore, the identification of target objects in each lateral range of real-time scene images that have interaction needs with the vehicle includes: Based on the real-time scene image, an initial object with interactive potential and key information of the initial object are obtained, wherein the key information includes the type label and pixel coordinates of the initial object; Obtain the preset spatial boundary of the lateral range corresponding to the sunshade, verify the pixel coordinates of the initial object, and obtain candidate interactive objects; Based on the real-time scene images, the behavior, posture, and movement trends of the candidate interactive objects are analyzed to obtain the target objects that have interaction needs with the vehicle.

[0008] Furthermore, the collaborative planning based on the interactive association features to obtain the linkage strategy and the scene response information corresponding to each sunshade includes: The scene priority ranking is performed based on the interaction association features corresponding to each sun visor, and the scene priority ranking results are obtained. The scene priority ranking results include emergency interaction scenarios and regular guidance scenarios. A linkage strategy is generated based on the scene priority ranking result. The linkage strategy includes the number of sun visors to be flipped, the flipping sequence of the sun visors, and the display coordination method. Based on the linkage strategy and the interaction requirements of the target object corresponding to each sun visor, preset response information is matched, and the preset response information is adjusted using the relative dynamic characteristics of the target object and the vehicle to obtain the scene response information corresponding to each sun visor.

[0009] Furthermore, adjusting the preset response information using the relative dynamic characteristics of the target object and the vehicle to obtain scene response information corresponding to each sun visor includes: The information update cycle is calculated based on the relative movement speed in the aforementioned relative dynamic characteristics. Configure the update frequency of the dynamic elements in the preset response information according to the information update cycle, and configure the pointing angle of the guide icon in the preset response information using the relative orientation in the relative dynamic features to obtain the initial response content. The scene response information is obtained by configuring the dynamic display parameters of the initial response content based on the relative distance in the relative dynamic features.

[0010] Furthermore, the step of controlling the corresponding sun visor in the vehicle to flip outward according to the linkage strategy, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor, includes: The sun visor in the vehicle is controlled to simultaneously flip outwards to display corresponding scene response information on a display screen located on the outside of the sun visor; or, The sun visors in the vehicle are sequentially controlled to flip outwards according to a flipping sequence, so as to display the corresponding scene response information on a display screen located on the outside of the sun visors.

[0011] Furthermore, the method also includes: If there are multiple target objects with interactive requirements in the same side range, the display screen corresponding to that side range will be split into multiple display areas. The scene response information is allocated according to the priority of multiple target objects with interaction needs within the same lateral range to obtain exclusive prompt information; The specific prompt information will be displayed in the corresponding display area.

[0012] In a second aspect, embodiments of the present invention provide a control device for a sunshade display screen, the device comprising: The acquisition module is used to acquire real-time scene images of the lateral range corresponding to each sun visor in the vehicle; The analysis module is used to analyze the real-time scene images of each lateral range to obtain the interaction and correlation features in the real-time scene information; The planning module is used to perform collaborative planning based on the interaction association features to obtain the linkage strategy and the scene response information corresponding to each sunshade. The execution module is used to control the corresponding sun visor in the vehicle to flip outward according to the linkage strategy, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor.

[0013] Thirdly, embodiments of the present invention provide a computer device, including: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the method described in the first aspect or any corresponding embodiment thereof.

[0014] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer instructions that cause a computer to perform the method described in the first aspect or any of its corresponding embodiments.

[0015] The method provided in this application has the following beneficial effects: The method provided in this application acquires real-time scene images of the lateral range corresponding to each sun visor in the vehicle, enabling comprehensive capture of dynamic information of the environment on both sides. This provides an accurate and real-time data foundation for subsequent scene analysis, ensuring the timeliness and reliability of the response mechanism. Secondly, by analyzing the real-time scene images of each lateral range to extract interactive correlation features, the specific needs of the scenes on both sides can be accurately understood, thus providing key decision-making basis for differentiated responses. Based on the interactive correlation features, collaborative planning is performed to generate linkage strategies and scene response information corresponding to each sun visor, realizing intelligent coordination of dual-screen content and effectively improving the pertinence and efficiency of information transmission. According to the linkage strategy, the corresponding sun visor is controlled to flip outward and display scene response information on the outer display screen, ensuring that the displayed content is automatically presented when needed, enhancing the interaction capability with the external environment, and seamlessly restoring the normal state after the scene ends. This solves the problem in the prior art where the display screen can not adapt to changing scenes due to independent display or fixed content, significantly improving vehicle safety and user experience.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] According to embodiments of the present invention, a control method, apparatus, device, and vehicle for a sun visor display screen are provided. It should be noted that the steps shown in the flowcharts in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0020] This embodiment provides a control method for a sunshade display screen. Figure 1 This is a flowchart of a control method for a sunshade display screen according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps: Step S101: Obtain real-time scene images of the lateral range corresponding to each sun visor in the vehicle.

[0021] It should be noted that the sun visor refers to the components on the left and right sides of the vehicle used to block sunlight, and its outer side is pre-installed with a display screen for displaying information to the outside of the vehicle; the lateral range corresponding to the sun visor refers to the specific monitoring area on the side of the vehicle that is respectively bound to the left and right sun visors. The lateral range corresponding to the left sun visor is centered on the left side of the vehicle and covers an area of ​​2-5 meters around the driver's side door (including the walking path of people approaching the driver's side door). The lateral range corresponding to the right sun visor is centered on the right side of the vehicle and covers a road area 1-3 meters wide on the right side and the adjacent sidewalk (including the potential path for pedestrians to cross the road); real-time scene image refers to continuous image data that can dynamically reflect the environmental conditions (including people, objects and actions) within the above-mentioned lateral range, and the image must be clear and without significant delay.

[0022] In this embodiment of the application, image acquisition is completed based on a scene capture device, which is specifically divided into three parts: Part 1: Install surround-view cameras on the vehicle that match the lateral range of the left and right sun visors. The left camera can be fixed below the left rearview mirror or the left B-pillar. Adjust the lens angle to ensure that the shooting angle completely covers the left lateral range (such as a rectangular area of ​​3 meters in front of the driver's door and 2 meters to the side) to avoid missing the critical path of the designated driver approaching the driver's door. The right camera can be fixed below the right rearview mirror or the right B-pillar. The field of view must cover the road to the right of the vehicle (at least 3 meters wide) and the adjacent sidewalk (at least 5 meters long) to ensure that the complete trajectory of pedestrians entering the road from the sidewalk can be captured. At the same time, the camera parameters need to be pre-configured, such as setting the resolution to 1920×1080 (to ensure clear details and be able to identify clothing logos, gait features, etc.) and lens distortion correction (to avoid the inaccuracy of target object position judgment due to distortion).

[0023] Part Two: The camera continuously captures images at a preset frame rate of 15-30 frames per second. Furthermore, the camera must possess environmental adaptability: automatically activating anti-glare mode in bright daylight (adjusting exposure parameters to reduce overexposure and ensure clear capture of pedestrian facial contours); automatically switching to infrared fill light mode at night or in low light (fill light distance covers the lateral range to avoid blurring of human features due to insufficient light); and activating lens defogging function in rainy or foggy weather (removing water vapor through heated lenses or airflow to ensure image clarity). For example, when a vehicle is parked on the roadside at night, the left-side camera, using infrared fill light, can clearly capture the folding electric scooter and driver's uniform identification carried by the driver within 10 meters, while the right-side camera can clearly capture the gait and direction of movement of pedestrians within 5 meters.

[0024] Part Three: Real-time scene images captured by the cameras are first formatted (using JPEG or H.264 format to compress data volume and reduce transmission bandwidth usage while ensuring clarity), and then transmitted to subsequent processing units (such as the image preprocessing module of the central control unit) via the vehicle's CAN bus (Controller Area Network bus, the standard data transmission bus between electronic devices inside the vehicle, enabling low-latency and high-reliability data interaction). Real-time data transmission is crucial; the time from acquisition to transmission of a single frame to the processing unit must be controlled within 100-200 milliseconds to avoid delays in subsequent scene analysis. For example, after the right-side camera captures an elderly person beginning to cross the road, the image is transmitted to the central control unit within 200 milliseconds, allowing time for subsequent judgment on whether to display a courtesy prompt.

[0025] Step S102: Analyze the real-time scene images of each lateral range to obtain the interactive correlation features in the real-time scene information.

[0026] It should be noted that interactive correlation features refer to a set of features that comprehensively reflect the interaction needs and dynamic relationship between the target object and the vehicle. It is composed of the target object's unique identification features and its dynamic relationship parameters with the vehicle, providing a core basis for subsequent collaborative planning. The target object refers to the object within the corresponding lateral range of the sun visor that has a clear interaction need with the vehicle (such as a chauffeur needing to confirm the driver's seat, or a pedestrian needing to cross the road). The initial object refers to the object scanned from the real-time scene image that has the potential to interact with the vehicle (such as people within the lateral range), which needs further screening. The preset spatial boundary refers to the effective interaction space boundary set in advance for each lateral range of the sun visor (such as the area on the left centered on the driver's door with a radius of 2-5 meters, and the area on the right centered on the right side of the vehicle, covering a 1-3 meter wide road and adjacent sidewalk), used to determine whether the object is in the effective interaction area. The key features of the object refer to the unique identification features of the target object (such as the chauffeur's clothing and carried items, the elderly person's gait and facial contours). The relative dynamic features refer to the dynamic relationship parameters between the target object and the vehicle (or driver's door, vehicle body) (such as relative distance, relative speed, and relative orientation).

[0027] In this embodiment, real-time scene images of each lateral range are analyzed to obtain interactive correlation features in the real-time scene information. This is achieved by relying on the central control unit and combining image data transmitted via the vehicle's CAN bus to complete the analysis process: The central control unit calls an image recognition algorithm (such as a CNN convolutional neural network) to scan the real-time scene images frame by frame, identify initial objects with interactive potential, such as people in the lateral range, and label key information: type label and pixel coordinates; The central control unit first retrieves the pre-stored preset spatial boundary parameters of each sun visor's lateral range, and then uses a perspective transformation algorithm to convert the pixel coordinates of the initial objects into actual spatial coordinates, and determines whether the actual coordinates fall within the preset spatial boundary. Initial objects falling within the boundary are candidate interactive objects; The central control unit analyzes the behavior posture and movement trend of candidate interactive objects through multiple consecutive frames of images, and candidate objects that meet the interaction requirements are target objects; The target objects are tracked and identified to obtain key features and relative dynamic features of the objects; Key features of the objects are extracted and relative dynamic features are calculated; Interactive correlation features are constructed based on the key features and relative dynamic features of the objects, and the finally generated interactive correlation features will serve as the core input data for collaborative planning.

[0028] Step S103: Perform collaborative planning based on interactive association features to obtain linkage strategies and scene response information corresponding to each sunshade.

[0029] It should be noted that collaborative planning refers to the overall decision-making process by which the central control unit, combining the interactive characteristics of the left and right sun visors of the vehicle, comprehensively judges the scene type, determines the sun visor action rules, and the content of the display screen; linkage strategy refers to the sun visor control rules formulated to achieve dual-screen collaboration, including the number of sun visors to be flipped (single or double sides), the flipping sequence (simultaneous or sequential), and the display collaboration method (each screen displays adapted content); scene response information refers to the dynamic content displayed on the outer display screen of the sun visor for the target object, which is adjusted from a preset template based on the dynamic characteristics of the target object; emergency interaction scenario refers to the scenario involving people Scene response scenarios are categorized into several types: safety-related scenarios (such as pedestrians crossing the road) and scenarios requiring priority warnings; regular guidance scenarios refer to scenarios that only require directional or informational guidance (such as a designated driver looking for the driver's side door) and have lower priority; preset response information refers to the basic display templates pre-stored by the central control unit that match typical target objects (such as a dynamic arrow pointing to the driver's side door on the left screen and text indicating "yield to pedestrians" on the right screen); dynamic elements refer to the parts of the scene response information that can change with the state of the target object (such as text flashing and arrow pointing); dynamic display parameters refer to the parameters that adjust the visual effects of the scene response information (such as text flashing frequency, number of arrow flashes, and font size).

[0030] In this embodiment, the central control unit first extracts key information of the target object from the interaction association features of the left and right sun visors. Based on preset rules, it determines the left-side chauffeur guidance scenario as a regular guidance scenario and the right-side elderly crossing the road scenario as an emergency interaction scenario, with the emergency scenario having a higher priority than the regular scenario, thus completing the scenario priority ranking. Then, based on the ranking result, it generates a linkage strategy, determining that since there are target objects on both sides, the left and right sun visors need to be flipped, and for the synchronous response scenario, it controls both sun visors to flip outwards simultaneously. At the same time, it clarifies the display coordination method of adapting the left screen to regular guidance and the right screen to emergency warning. Finally, it calculates the information update cycle based on the relative movement speed of the target object, configures the dynamic element update frequency according to the update cycle, and adjusts the left screen arrow to point to the driver's door handle in combination with the relative orientation to obtain the initial response content. Finally, it adjusts the display parameters based on the relative distance, and finally obtains the scenario response information of the dynamic green arrow on the left screen and the orange warning text on the right screen.

[0031] In step S104, the corresponding sun visor in the vehicle is controlled to flip outward according to the linkage strategy, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor.

[0032] It should be noted that, Figure 2 This is a schematic diagram of the structure of the display screen after the sun visor is flipped up, viewed from outside the vehicle. Figure 2 As shown, when the sun visor 1 on the upper side of the steering wheel is flipped outward, the display screen 2 located on the outside of the sun visor can be used to display the generated content to the target object outside the vehicle, thereby realizing information interaction between the vehicle and the object outside the vehicle.

[0033] In this embodiment, the central control unit first retrieves the linkage strategy, extracts the number of sun visors to be flipped and the flipping timing parameters of the sun visors, and then sends an electrical signal control command to the vehicle sun visor drive module to drive the corresponding sun visor to flip outward. If the linkage strategy clearly indicates that there is a target object on both sides, the left and right sun visors are controlled to flip outward simultaneously, and the synchronous drive motor ensures that both screens are in place at the same time, avoiding waiting for the target object. If the linkage strategy indicates that there is a target object on only one side (e.g., only the left side has a designated driver and there is no pedestrian on the right side), only the left sun visor is controlled to flip outward according to the flipping timing. After the sun visor flips to the preset angle, the central control unit immediately moves the sun visor outward. The side displays send scene response information, causing the left screen to display a dynamic green arrow pointing to the driver's door (flashing twice per second) as needed, and the right screen to display the orange text "Give way to the elderly, please pass slowly" (the flashing frequency is adjusted according to the elderly person's speed). At the same time, the central control unit continuously receives feedback from the surround-view camera on the status of the target object (such as whether the driver's door is open or closed to determine if the designated driver has boarded the vehicle, and whether the elderly person has fully entered the opposite sidewalk). Once the target object's interaction request is completed, a reset command is immediately sent to control the sun visor to rotate in the opposite direction to restore it to its initial retracted state, and the display screen is switched to the normal display (such as the left screen displaying the remaining battery life and the right screen displaying the time), achieving a seamless transition between the interactive scene and the normal state.

[0034] In this embodiment of the application, the real-time scene image of each lateral range is analyzed to obtain the interaction association features in the real-time scene information, including the following steps A1-A3: Step A1: Identify target objects in each lateral range of real-time scene images that have interaction needs with the vehicle.

[0035] In this embodiment of the application, identifying target objects in each lateral range of real-time scene images that have interaction needs with the vehicle includes the following steps A11-A13: Step A11: Scan the real-time scene image to obtain the initial object with interactive potential and the key information of the initial object, including the type label and pixel coordinates of the initial object.

[0036] Specifically, the initial object with interactive potential refers to the object identified from the real-time scene image that may interact with the vehicle (such as requiring guidance or warning) (e.g., people within the lateral range, excluding objects such as trees and streetlights that have no interactive potential). The type label refers to the category label initially marked based on the object's appearance characteristics (clothing, carried items, gait, etc.) (e.g., "suspected driver" or "suspected elderly"). The pixel coordinates refer to the coordinate values ​​used to locate the initial object's position in the two-dimensional coordinate system of the real-time scene image (with the upper left corner of the image as the origin, the horizontal axis as the x-axis, and the vertical axis as the y-axis).

[0037] The implementation can include: the central control unit calls an image recognition algorithm (such as a CNN convolutional neural network) to perform a frame-by-frame pixel-level scan of the real-time scene images of the corresponding lateral range of the vehicle's left and right sun visors. The algorithm identifies the initial object with interactive potential through preset feature templates (such as the typical color of the chauffeur's uniform, the shape of the chauffeur's box, and common gait characteristics of the elderly). At the same time, it automatically labels key information: for the identified person, it labels the person as "suspected chauffeur" based on whether the clothing has a chauffeur's logo or whether the person is carrying a folding electric vehicle, and labels the person as "suspected elderly" based on facial contours and slow gait characteristics. The image coordinate calculation module determines the specific pixel coordinates of the initial object in the image (such as x=500 pixels, y=300 pixels), and finally outputs a dataset containing the initial object and corresponding key information.

[0038] Step A12: Obtain the preset spatial boundary of the lateral range corresponding to the sunshade, verify the pixel coordinates of the initial object, and obtain the candidate interactive object.

[0039] Specifically, each sun visor has a pre-defined lateral range of interactive actual space (not image range). The left sun visor corresponds to a pre-defined spatial boundary centered on the driver's side door, covering a circular area with a radius of 2-5 meters (ensuring coverage of the path the chauffeur takes to approach the driver's side door). The right sun visor corresponds to a pre-defined spatial boundary centered on the right side of the vehicle, covering a rectangular area with a width of 1-3 meters and a length of 5 meters (covering potential paths for pedestrians crossing the road). Candidate interactive objects refer to the initial objects whose actual positions are within the pre-defined spatial boundaries after spatial verification.

[0040] The implementation method may include: the central control unit first retrieves the preset spatial boundary parameters of the corresponding lateral range of the left and right sun visors from the vehicle storage module, and then uses a perspective transformation algorithm (to establish a mapping relationship between image pixel coordinates and actual spatial coordinates) to convert the pixel coordinates of the initial object into actual spatial coordinates (e.g., converting the pixel coordinates of the "suspected driver" on the left into actual spatial coordinates 3 meters away from the driver's side door). Then, the converted actual spatial coordinates are compared with the preset spatial boundaries: if the actual spatial coordinates of the initial object fall within the preset boundary of 2-5 meters on the left or 1-3 meters on the right (e.g., the "suspected driver" is actually 3 meters away from the driver's side door and is within the left boundary; the "suspected elderly" is actually in the 2-meter wide area on the right and is within the right boundary), then the initial object is determined to be a candidate interaction object; if the actual position of the initial object exceeds the preset boundary (e.g., the "suspected driver" on the left is 6 meters away from the driver's side door), then the initial object is excluded, and finally all candidate interaction objects are obtained.

[0041] Step A13: Based on real-time scene images, analyze the behavior, posture, and movement trends of candidate interactive objects to obtain target objects that have interaction needs with the vehicle.

[0042] Specifically, behavioral posture refers to the limb movements and behavioral state of candidate interaction objects (such as whether they move in a specific direction or have a clear target action), movement trend refers to the movement direction of candidate interaction objects obtained through analysis of multiple consecutive frames of images (such as moving towards the driver's side door or towards the middle of the road), and target objects that have interaction needs with the vehicle refer to candidate interaction objects whose behavioral posture and movement trend indicate that they need the vehicle to provide information guidance or warnings.

[0043] The implementation method may include: the central control unit retrieves 10-20 consecutive frames of real-time scene images (ensuring dynamic changes can be analyzed), and performs dynamic analysis on candidate interaction objects: for the left-hand "suspected driver" candidate object, the behavior posture (whether there is a movement of looking up to observe the vehicle and walking towards the driver's side door) and movement trend (determining whether it turns from the direction away from the driver's side door to the direction of approaching the driver's side door by the change of actual spatial coordinates in multiple frames) are analyzed through inter-frame comparison. If it is detected that it continues to walk towards the driver's side door and observes the vehicle, it indicates that there is an interaction need to "confirm the position of the driver's side door", and it is determined to be the target object of the driver; for the right-hand "suspected elderly" candidate object, the behavior posture (whether there is a movement of lifting a foot and moving towards the middle of the road) and movement trend (determining whether it moves from the sidewalk to the middle of the road) are analyzed. If it is detected that it has stepped into the road area and the direction of movement is towards the opposite side of the road, it indicates that there is an interaction need for the vehicle to give way, and it is determined to be the target object of the elderly; finally, all target objects with interaction needs with the vehicle are filtered out, and the recognition process of this step is completed.

[0044] Based on real-time scene image scanning, initial objects and key information are obtained, which can initially screen out objects with interactive potential and record their type and location, laying the foundation for subsequent processing. Candidate interactive objects are obtained by verifying the pixel coordinates of the initial objects through preset spatial boundaries, which can exclude objects that are outside the effective interaction range, reduce invalid calculations, and improve processing efficiency. The target object is obtained by analyzing the behavior, posture and movement trend of the candidate objects, which can accurately determine whether the object has a real interaction need (such as approaching a vehicle or needing guidance), ensuring the accuracy of the recognition results and providing a reliable target basis for subsequent interactions.

[0045] Step A2 involves tracking and identifying the target object to obtain its key features and the relative dynamic features between the target object and the vehicle.

[0046] Specifically, the central control unit employs a Kalman filter target tracking algorithm, continuously tracking target objects (such as designated drivers and the elderly) based on multiple frames of real-time scene images continuously acquired by surround-view cameras, avoiding recognition interruptions caused by target movement or occlusion. Simultaneously, it extracts key features of the target object using image feature extraction algorithms (such as SIFT feature matching). For example, for designated drivers, it identifies the company logo on their uniform and the brand characteristics of their folding electric bikes; for the elderly, it identifies the distribution of their gray hair and the color and shape of their cane. Furthermore, it calculates relative dynamic features by combining the actual spatial coordinates of the target object in multiple frames (obtained through perspective transformation): the relative speed is obtained by the ratio of the coordinate difference between two consecutive frames to the frame interval (e.g., 0.3 m / s for designated drivers, 0.5 m / s for the elderly); the relative distance is obtained using the distance formula between real-time coordinates and fixed vehicle coordinates (e.g., the position of the driver's side door) (e.g., the designated driver is 1.5 meters from the driver's side door); and the relative orientation is obtained using an azimuth calculation model (e.g., the designated driver is 30° in front of the driver's side door). Finally, it outputs a dataset containing key object features and relative dynamic features.

[0047] Step A3: Construct interactive association features based on key object features and relative dynamic features.

[0048] Specifically, the central control unit maps the key features and relative dynamic features of the same target object together, and constructs a unified interactive feature data structure through data fusion algorithms (such as feature splicing and weight allocation): For the chauffeur target object, the interactive features are integrated into the key features of the object: chauffeur uniform logo 'XX Chauffeur', folding electric vehicle 'Y brand'; relative dynamic features: relative distance to the driver's side door 1.5 meters, relative speed 0.3 m / s, relative orientation 30° in front of the driver's side door; For the elderly target object, the key features are integrated into the key features of the object: white hair and brown cane; relative dynamic features: relative distance to the right side of the vehicle body 2 meters, relative speed 0.5 m / s, relative orientation 60° to the middle of the right side of the vehicle; Each interactive feature contains a unique identifier (corresponding to a specific target object) and a timestamp (marking the feature collection time) to ensure the timeliness and correspondence of the features, ultimately forming feature data that can be directly used for collaborative planning.

[0049] By identifying target objects that require interaction with the vehicle, the system can accurately pinpoint the objects that need information exchange, avoiding invalid responses to irrelevant objects. Tracking and identifying target objects yields key features and relative dynamic characteristics, comprehensively capturing the object's unique attributes (such as type and characteristics) and its dynamic relationship with the vehicle (such as distance, speed, and orientation), providing detailed information for subsequent interactions. Based on these features, interaction association features can be constructed, integrating object information and dynamic relationships to form a complete interaction basis, thereby improving the accuracy and adaptability of the sun visor display screen's interaction with the target object.

[0050] In this embodiment of the application, collaborative planning is performed based on interaction association features to obtain the linkage strategy and scene response information corresponding to each sunshade, including: Step B1: Based on the interaction association features corresponding to each sun visor, the scene priority is sorted to obtain the scene priority sorting result, which includes emergency interaction scenarios and regular guidance scenarios.

[0051] Specifically, the central control unit extracts the core information from the interaction-related features of each sun visor (such as the relative moving speed of the elderly target on the right (0.5m / s) and the relative direction of movement towards the middle of the road, and the relative distance of the designated driver target on the left (1.5m) and the relative direction of movement towards the driver's door). Based on the preset priority rules (movement trend scenarios involving personnel safety have higher priority than simple guidance scenarios), the right-side scenario is determined to be an "emergency interaction scenario" and the left-side scenario is determined to be a "regular guidance scenario". The emergency scenario is determined to have higher priority than the regular scenario, and the final scenario priority ranking result is output.

[0052] Step B2: Generate a linkage strategy based on the scene priority ranking result. The linkage strategy includes the number of sun visors to be flipped, the flipping sequence of the sun visors, and the display coordination method.

[0053] Specifically, the central control unit determines the number of sun visors to be flipped (e.g., if there are two, both sun visors need to be flipped) based on the priority ranking of the scenarios (emergency interaction scenario on the right, regular guidance scenario on the left, with target objects on both sides). If the scenarios on both sides need to respond synchronously to avoid the target objects waiting, the flipping sequence of the sun visors is set to flip simultaneously. Based on the differences in scenario types, the display coordination method is clearly defined as adapting regular guidance content (such as an arrow pointing to the driver's door) on the left screen and emergency warning content (such as courtesy text) on the right screen, and finally generating a linkage strategy that includes the above three elements.

[0054] Step B3: Match preset response information according to the linkage strategy and the interaction requirements of the target object corresponding to each sun visor, and adjust the preset response information using the relative dynamic characteristics of the target object and the vehicle to obtain the scene response information corresponding to each sun visor.

[0055] Prioritizing scenarios based on interactive association features can distinguish between emergency interaction scenarios and regular guidance scenarios, ensuring that vehicles respond first to emergency scenarios involving safety and improving the rationality of interactions. Based on the prioritization results, a linkage strategy is generated, specifying the number of flips, timing, and display coordination methods. This coordinates the actions and displays of multiple sun visors, achieving orderly collaboration. Matching and adjusting preset response information to obtain scenario response information allows the displayed content to adapt to the interaction needs and dynamic states of the target object, ensuring the effectiveness of information transmission and thus improving the collaborative interaction effect of the sun visor display screen.

[0056] In this embodiment, the preset response information is adjusted using the relative dynamic characteristics of the target object and the vehicle to obtain the scene response information corresponding to each sun visor, including the following steps B31-B33: Step B31: Calculate the information update cycle based on the relative movement speed in the relative dynamic features.

[0057] Specifically, the information update cycle refers to the update interval of dynamic content (such as flashing text and arrow pointing) in the scene response information, which is used to ensure that the displayed content is synchronized with the real-time status of the target object. The implementation method is as follows: the central control unit extracts the relative movement speed of the target object from the relative dynamic features (such as 0.5m / s for the elderly and 0.3m / s for the designated driver), and calculates it according to the preset calculation formula (information update cycle = base cycle ÷ relative movement speed coefficient, where the faster the speed, the larger the coefficient). For example, when the elderly move faster, the coefficient is set to 2, the base cycle is 1 second, then the information update cycle = 1 ÷ 2 = 0.5 seconds, ensuring that the fast-moving target object can see the updated content in time; when the designated driver moves slower, the coefficient is set to 1, the information update cycle = 1 second, balancing the display stability and real-time performance.

[0058] Step B32: Configure the update frequency of dynamic elements in the preset response information according to the information update cycle, and configure the pointing angle of the guide sign in the preset response information using the relative orientation in the relative dynamic features to obtain the initial response content.

[0059] Specifically, dynamic elements refer to the parts of the preset response information that can change over time (such as flashing text or moving arrows), directional signs refer to symbols used for directional guidance (such as arrows pointing to the driver's side door), and initial response content refers to the basic display content after adjusting the frequency of dynamic elements and the angle of directional signs. The implementation method is as follows: The central control unit first converts the information update cycle (such as 0.5 seconds in the elderly scenario and 1 second in the chauffeur scenario) into the dynamic element update frequency (frequency = 1 ÷ cycle, i.e., 2 times / second in the elderly scenario and 1 time / second in the chauffeur scenario), and configures the flashing or moving frequency of dynamic elements in the preset response information (such as courtesy text in the elderly scenario and arrows in the chauffeur scenario); then it extracts the relative orientation in the relative dynamic features (such as the chauffeur being 30° in front of the driver's side door and the elderly being 60° in the middle of the right side of the vehicle), and adjusts the pointing angle of the directional signs (such as arrows in the chauffeur scenario) through an angle mapping algorithm so that they accurately face the target object, and finally forms the initial response content.

[0060] Step B33: Configure the dynamic display parameters of the initial response content based on the relative distance in the relative dynamic features to obtain scene response information.

[0061] Specifically, dynamic display parameters refer to parameters that affect the visual effect of the initial response content (such as font size, display brightness, and flicker intensity), while scene response information refers to the content finally displayed on the sun visor display screen after all parameters have been adjusted. The implementation method is as follows: the central control unit extracts the relative distance from the target object's relative dynamic features (such as the distance between the valet driver and the driver's side door being 1.5 meters, and the distance between the elderly person and the right side of the vehicle being 2 meters), and configures the dynamic display parameters according to preset rules (the closer the distance, the greater the parameter adjustment range to enhance visibility): when the valet driver is close, the font size of the arrow in the initial response content is increased by 20%; when the elderly person is close, the brightness of the courtesy text is increased by 15% to ensure that the target object is clearly visible; after parameter adjustment, scene response information that can be directly used for display is obtained (such as the enlarged arrow and highlighted text).

[0062] Calculating the information update cycle based on relative movement speed allows the update frequency of scene response information to match the object's movement speed, avoiding information lag or over-updating and ensuring real-time information. Configuring the frequency of dynamic elements and the guide angle based on the update cycle to obtain the initial response content allows the rhythm of dynamic element changes (such as flashing text) to adapt to the object's state, and guide markers (such as arrows) to accurately point to the object, enhancing information clarity. Configuring dynamic display parameters based on relative distance to obtain scene response information allows adjusting the display effect (such as font size and brightness) according to the distance between the object and the vehicle, ensuring the object clearly perceives the information and improving the reliability of information transmission.

[0063] In this embodiment, the corresponding sun visor in the vehicle is controlled to flip outward according to the linkage strategy, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor, including the following steps C1-C2: Step C1: Control the sun visor in the vehicle to flip outward simultaneously, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor.

[0064] Specifically, simultaneous outward flipping refers to multiple sun visors initiating their flipping action at the same time and synchronously reaching a preset angle. The implementation method is as follows: the central control unit sends a synchronous electrical signal to the drive module (such as a servo motor) of the left and right sun visors of the vehicle according to the simultaneous flipping instruction in the linkage strategy. The drive motor simultaneously drives the sun visors to flip outward from the initial retracted state (the flipping angle is preset to 30-45° to ensure that the display screen is facing the side target object). After the position sensor feedback that the sun visor is in place, the scene response information (such as the guide arrow on the left screen and the courtesy text on the right screen) is immediately sent to the display screens on both sides to realize the simultaneous display of the corresponding content on both screens.

[0065] Step C2: Sequentially control the sun visors in the vehicle to flip outwards according to the flipping sequence, so as to display the corresponding scene response information on the display screen set on the outside of the sun visor.

[0066] Specifically, the flip sequence refers to the preset order in which the sun visors flip (e.g., left before right or right before left). The implementation method is as follows: the central control unit sends a delayed electrical signal to the drive module of the corresponding sun visor according to the flip sequence in the linkage strategy (e.g., to prioritize emergency scenarios, the right sun visor is flipped first). The right motor is driven first to flip the sun visor. After the right side is in position (about 0.5 seconds), the left motor is driven to flip the sun visor. After each sun visor is in position, the corresponding scene response information is displayed (emergency warning on the right, normal guidance on the left), avoiding possible mechanical interference from simultaneous flipping.

[0067] Controlling the sun visors to flip outwards simultaneously and display information allows for synchronized responses to interaction needs on both sides of the vehicle, preventing target objects from waiting and improving the timeliness of interaction. Sequentially controlling the sun visors to flip and display information according to the flipping sequence enables orderly responses based on scene priorities, avoiding mechanical conflicts caused by multiple sun visors moving simultaneously and ensuring smooth operation. Both flipping methods are used in conjunction with a display screen to show scene response information, which can flexibly adapt to different interaction scenarios, ensuring that target objects outside the vehicle can obtain the information they need in a timely manner, thus improving the flexibility and effectiveness of interaction.

[0068] In this embodiment of the application, the method further includes: Step S201: If there are multiple target objects with interactive requirements in the same side range, then the display screen corresponding to the side range is split into multiple display areas.

[0069] In this embodiment of the application, the split-screen operation refers to dividing the display interface of a single sun visor display screen into multiple independent and non-overlapping sub-regions. The display area refers to each sub-region after the split screen is used to display information of a target object separately. The implementation method is as follows: when the central control unit detects that there are multiple target objects (such as the elderly and children) in the same lateral range (such as the right side), it calls the display screen split-screen algorithm to divide the right display screen interface into two equal-sized display areas along the horizontal or vertical direction according to the number of target objects (such as 2). Each area is assigned an independent display coordinate range to ensure that the information display does not overlap.

[0070] Step S202: Assign scene response information according to the priority of multiple target objects with interaction needs within the same lateral range to obtain exclusive prompt information.

[0071] In this embodiment, the priority of the target object refers to the sorting based on the urgency of the interaction needs (e.g., children have a higher priority than the elderly because children have weaker reaction abilities), and the exclusive prompt information refers to the scene response information customized for each target object (e.g., displaying a cartoon courtesy icon for children and a text prompt for the elderly). The implementation method is as follows: the central control unit determines the priority (children > elderly) based on the interaction association characteristics of the target object (e.g., children's relative movement speed is 0.6m / s, and the elderly's is 0.4m / s), decomposes the scene response information into content adapted to different objects, generates exclusive prompts such as "cartoon arrow, 'Please be careful'" for children, generates exclusive prompts such as "orange text, 'Please pass slowly'" for the elderly, and marks the corresponding priority.

[0072] Step S203: Display the exclusive prompt information in the corresponding display area.

[0073] In this embodiment, the corresponding display area refers to the split-screen area that matches the priority of the target object (e.g., the left or upper area corresponds to a high-priority object). The implementation method is as follows: the central control unit sorts according to priority and sends the exclusive prompt information of the high-priority target object (e.g., a child) to the area that is easier to observe after splitting the screen (e.g., the upper half of the display screen), and sends the information of the low-priority object (e.g., the elderly) to the lower half. The coordinate positioning ensures that each exclusive prompt information is accurately displayed in the corresponding area, and receives the dynamic feature update information of the target object in real time, and adjusts the display content of each area synchronously.

[0074] When there are multiple target objects in the same lateral range, split-screen operation can be performed to obtain multiple display areas, which can solve the conflict problem of displaying multiple object information on a single screen and improve the space utilization of the display screen. Assigning scene response information according to the priority of target objects can ensure that the information of high-priority objects (such as more urgent interaction needs) is displayed first, improving the targeting of the interaction. Displaying the exclusive prompt information in the corresponding area can enable each target object to obtain independent and matching information, avoid information confusion, and ensure the accuracy and effectiveness of interaction in multi-object scenarios.
