Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a display control method, device, and vehicle for vehicles. Background Technology

[0002] With the rapid iteration of vehicle intelligence and connectivity technologies, autonomous vehicles and intelligent connected vehicles are gradually becoming the mainstream of development in the transportation sector. Currently, information interaction between vehicles and the external environment mainly relies on traditional methods. For example, simple devices such as lights and horns transmit basic signals, or information interaction is completed through auxiliary methods such as gesture communication. However, traditional light signals can only convey single, fixed information such as turning and braking, and cannot express complex driving intentions. Horn warnings are prone to noise pollution and cannot effectively alert hearing-impaired individuals or distracted road users. Gesture communication is greatly limited by the scenario, and its information transmission efficiency and accuracy are insufficient.

[0003] Therefore, how to break through the limitations of traditional interaction methods and improve the efficiency and accuracy of vehicle-external interaction has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] This application provides a display control method, device, and vehicle for a vehicle, to solve the problems of low interaction efficiency and accuracy of traditional interaction methods.

[0005] In a first aspect, this application provides a display control method for a vehicle, the method comprising: During vehicle operation, acquire vehicle status information and / or environmental information surrounding the vehicle. The display content is generated based on the vehicle status information and / or the environmental information, and the sun visor of the vehicle is triggered to flip outward. The display content is displayed on a display screen located on the outside of the sun visor. The display content is the interaction content between the vehicle and the external interactive objects around the vehicle. After the sun visor is flipped outward, the display screen on the outside of the sun visor faces the external interactive objects.

[0006] The method provided in this embodiment dynamically acquires vehicle status information and / or environmental information during vehicle operation. Based on this, it intelligently generates targeted display content for external interactions and displays it to external interactive objects using an outward-flipping display screen on the outside of the sun visor. This achieves proactive and precise information interaction between the vehicle and its external environment. By transforming the sun visor into an interactive carrier with display functionality, and ensuring the display screen accurately faces the external interactive object through a flipping mechanism, the method solves the problem of traditional vehicles lacking an effective direct external information output channel. This allows the display content generated based on vehicle status information and / or environmental information to be intuitively perceived by the external interactive object. The display content is generated based on real-time acquired vehicle status and environmental information, ensuring the timeliness and relevance of information and reducing information asymmetry in complex traffic scenarios. This interaction method expands the dimensions of vehicle information transmission, no longer limited to traditional methods such as lights and horns. Through visualized display content (such as intent prompts and warning information), it improves the accuracy and user-friendliness of information transmission, helping to reduce the risk of traffic accidents and improve road traffic efficiency.

[0007] In one optional implementation, generating display content based on the vehicle status information and / or the environmental information includes: Based on the vehicle status information, the operating state of the vehicle is determined; the operating state includes at least one of the following: intention to decelerate, intention to accelerate, intention to drive at a constant speed, intention to turn, intention to park out, intention to park in, intention to overtake by using the other lane, intention to go straight, intention to pull over, or intention to yield. Based on the environmental information, factors affecting the vehicle's driving are determined; these factors include at least one of: external interaction objects, the behavioral intentions of external interaction objects, or road environment characteristics. The display content is generated based on the operating status and / or the influencing factors.

[0008] The method provided in this embodiment can determine the specific operating states of a vehicle, such as deceleration and steering, through vehicle status information, and can determine the influencing factors affecting vehicle driving through environmental information, such as external interactive objects, the behavioral intentions of external interactive objects, or road environment characteristics. Display content can be generated through operating states and / or influencing factors, enabling external interactive objects to fully understand vehicle behavior and thus make more accurate responses, significantly improving the integrity of information transmission and decision support effect in complex traffic scenarios.

[0009] In one optional implementation, when the external interaction object includes an oncoming vehicle, generating display content based on the operating status and / or the influencing factors includes: When the oncoming vehicle shows an intention to slow down or yield, and the road environment features indicate that the current situation is a narrow road meeting scenario or a curve passage scenario, display content representing the oncoming vehicle's intention to slow down or yield is generated. When an oncoming vehicle intends to speed or obstruct the road, a prompt is generated to remind the oncoming vehicle to slow down or give way; wherein, the oncoming vehicle's intention to give way, speeding, and obstructing the road are behavioral intentions of the oncoming vehicle. When the vehicle shows an intention to slow down or yield, and the road environment features indicate that the current situation is a narrow road meeting scenario or a curve passage scenario, display content representing the vehicle's intention to slow down or yield is generated.

[0010] The method provided in this embodiment targets oncoming vehicles as the interactive object, combining their behavioral intentions with special scenarios such as narrow roads and curves to generate adapted display content. It can accurately identify benign intentions such as slowing down and yielding, as well as risky intentions such as speeding and lane obstruction, and then combine this with road environment characteristics to determine the danger of the scenario, ultimately generating differentiated display content. When vehicles meet on narrow roads, clearly conveying the yielding intentions of both parties can avoid road congestion caused by hesitation about who should go first. Timely warnings of dangerous intentions can force unsafe behaviors of oncoming vehicles, reducing the incidence of oncoming collisions from the source, while improving traffic order and efficiency in special road sections.

[0011] In one optional implementation, when the external interactive object includes a pedestrian, generating display content based on the operating status and / or the influencing factors includes: When a pedestrian intends to cross the road and the vehicle intends to slow down or yield, display content indicating that the pedestrian can safely cross is generated; wherein, the pedestrian's intention to cross the road is a behavioral intention of the external interactive object. When the vehicle has at least one of the following intentions: accelerating, maintaining a constant speed, turning, parking out, parking in, overtaking, going straight, or parking on the side of the road, a display message is generated to remind pedestrians to pay attention and avoid the vehicle.

[0012] The method provided in this embodiment generates a display indicating safe passage when a pedestrian intends to cross and a vehicle is preparing to yield, resolving pedestrian hesitation caused by uncertainty about whether the vehicle will slow down. When a vehicle is accelerating, turning, or otherwise potentially threatening to pedestrians, it proactively issues a yielding warning, mitigating the risk of pedestrians being inattentive. Compared to traditional horn warnings, this method is more inclusive (e.g., effective for hearing-impaired individuals) and can significantly reduce the probability of conflicts at pedestrian-vehicle intersections, especially in densely populated areas such as schools and commercial districts, significantly improving pedestrian safety when crossing the street.

[0013] In one optional implementation, generating display content based on the operating status and / or the influencing factors includes: When the road environment parameters in the road environment features meet the warning conditions for environmental risks, a display content is generated to prompt the external interactive object to pay attention to the corresponding environmental risks; the road environment parameters include at least one of the following: precipitation parameters, wind speed parameters, visibility parameters, road surface friction coefficient parameters, or ambient light intensity parameters.

[0014] The method provided in this embodiment monitors road environmental parameters such as precipitation and visibility in real time. When these parameters meet the warning conditions for environmental risks, it automatically generates corresponding environmental risk alerts. This transforms abstract parameter data into intuitive visual information, overcoming the limitations of traditional environmental warnings that rely on fixed roadside signs or broadcasts, and enabling real-time risk transmission in mobile scenarios. For example, during a sudden downpour, vehicle displays can immediately alert surrounding vehicles and pedestrians to be aware of slippery conditions, helping them adjust their speed and mode of travel in time, effectively reducing the incidence of traffic accidents caused by sudden environmental changes.

[0015] In one optional implementation, generating display content based on the operating state and / or the influencing factors includes: When the road environment features a parking lot direction landmark and the vehicle has the intention to park out or park in, display content including a guide arrow consistent with the direction of the landmark is generated.

[0016] The method provided in this embodiment combines the static environmental feature of parking lot directional landmarks with the dynamic intention of vehicles to park / exit, generating directional guide arrows. First, the direction indicated by the landmarks is identified, then matched with the vehicle's current parking intention, ensuring that the arrows reflect both the landmark specifications and the real-time movement trend of the vehicle. Especially in large parking lots or dimly lit environments, the intuitive arrow display helps surrounding vehicles and pedestrians anticipate vehicle trajectories, reducing collisions and congestion, and improving overall parking lot efficiency and safety.

[0017] In one optional implementation, when the vehicle is an operational vehicle and the vehicle status information further includes operational status, display content is generated based on the vehicle status information and / or the environmental information, including: Based on the operational status, display content representing the operational status is generated.

[0018] The method provided in this embodiment transforms the operational status of vehicles into visual display content, taking into account their unique characteristics. Differentiated information is customized according to different operational types. This allows surrounding vehicles and pedestrians to quickly understand the operational needs of the vehicles. When construction vehicles are operating, it can guide other vehicles to detour in advance; when buses are stopping, it can remind pedestrians to wait in an orderly manner. This ensures the safe and efficient operation of the vehicles while minimizing interference with normal traffic flow, achieving coordinated passage between operational vehicles and other vehicles.

[0019] In an optional implementation, after displaying the content via a display screen disposed on the outside of the sun visor, the method further includes: Detect changes in the vehicle status information and / or the environmental information; Based on the changes, determine the duration of the displayed content, or whether to update the displayed content; If it is determined that the display content needs to be updated, the display content is regenerated and displayed on the display screen. If it is determined that the displayed content will not be updated, the display screen will be turned off after the specified duration has elapsed.

[0020] The method provided in this embodiment establishes a dynamic monitoring mechanism for vehicle status and environmental information, continuously tracking changes in both to determine the update of displayed content or the duration of display. This overcomes the information lag problem that may occur with static displays. For example, when a vehicle changes from decelerating to accelerating, the display can instantly switch content to avoid misleading others. It also extends display time during sudden environmental changes to ensure effective information transmission, keeping external interactions always up-to-date and further improving the accuracy and safety of the interaction.

[0021] Secondly, this application provides a display control device for a vehicle, the device comprising: The first processing module is used to acquire vehicle status information and / or environmental information around the vehicle during vehicle operation. The second processing module is used to generate display content based on the vehicle status information and / or the environmental information, and trigger the sun visor of the vehicle to flip outward, and display the display content through a display screen set on the outside of the sun visor; the display content is the display content of the interaction between the vehicle and the external interactive objects around the vehicle, and after the sun visor is flipped outward, the display screen on the outside of the sun visor faces the external interactive objects.

[0022] Thirdly, this application provides a vehicle including a display screen and a controller, the display screen and the controller being communicatively connected, the display screen being disposed on the side of the vehicle facing external interactive objects around the vehicle after the sun visor is flipped outward, and the controller being used to execute the vehicle display control method of the first aspect or any corresponding embodiment described above.

[0029] Currently, the sun visors provided by related technologies are unable to intelligently display vehicle operating status, operating intentions, and prompts for interaction with the external environment.

[0030] Therefore, this application provides a vehicle display control method to solve the above problems. By using external displays, the trust issue of autonomous vehicles can be resolved to a certain extent, and the communication efficiency between vehicles and people can also be enhanced.

[0031] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0032] Figure 1 This is a flowchart of a vehicle display control method according to an embodiment of this application, such as... Figure 1 As shown, the process includes the following steps: S101: During vehicle operation, acquire vehicle status information and / or environmental information surrounding the vehicle.

[0033] In this application embodiment, the vehicle is a motor vehicle with intelligent perception, data processing and external interaction capabilities, including but not limited to autonomous vehicles, intelligent connected vehicles, new energy vehicles or operation vehicles.

[0034] In this embodiment, vehicle status information can characterize the vehicle's current operating parameters, operational behaviors, and driving intentions, specifically including dynamic operating parameters and operational command information. Dynamic operating parameters may include real-time vehicle speed, acceleration (acceleration / deceleration amplitude), steering angle, braking status (brake pedal travel, braking intensity), gear information (drive / reverse / neutral), remaining battery / fuel level, engine speed, etc. Operational command information may include driver-triggered turn signals, lane change requests, overtaking operations, parking commands, pulling over to the side of the road operations, and yielding operations (such as releasing the accelerator pedal and lightly applying the brakes), etc.

[0035] In this embodiment, the environmental information surrounding the vehicle can characterize the external traffic scene, road conditions, and the state of external interactive objects, which is crucial to ensuring that the displayed content matches the actual scene. Specifically, it includes: relevant information about external interactive objects and relevant information about the road environment. Relevant information about external interactive objects can include: object type, such as other vehicles, pedestrians, etc. Pedestrians can be further categorized as elderly people, children, traffic police, etc.; object location, such as distance and orientation relative to the vehicle; object dynamics, such as pedestrian movement speed / direction, and the speed / steering / braking status of other vehicles. Relevant information about the road environment can include: road type, such as urban roads, highways, narrow rural roads, parking lots, school areas, hospitals, etc.; road structure, such as straight roads, curves, slopes, intersections (crossroads / roundabouts), construction zones, etc.; traffic signs and markings, such as speed limit signs, yield signs, parking lot direction markings, zebra crossings, etc.

[0036] This embodiment utilizes vehicle-mounted sensors and onboard systems to collect real-time vehicle status information and / or environmental information surrounding the vehicle. This provides comprehensive data support for generating accurate and appropriate display content, preventing invalid or misleading interactive content due to missing information. As an example, vehicle-mounted sensors may include cameras, radar, lidar, vehicle speed sensors, etc.

[0037] In this embodiment of the application, "around the vehicle" specifically refers to a certain spatial range centered on the vehicle, covering the area where interactions or safety impacts may occur during vehicle operation. Specifically, it refers to the spatial range in front of the vehicle. This spatial range can be determined based on the detection capabilities of the sensors mounted on the vehicle, such as the effective detection range of a lidar or the clear recognition range of a camera.

[0038] S102: Generate display content based on vehicle status information and / or environmental information, and trigger the vehicle's sun visor to flip outward, displaying the content through a display screen located on the outside of the sun visor.

[0039] In this embodiment, the displayed content is the interaction content between the vehicle and external objects around the vehicle. After the sun visor is flipped outward, the display screen on the outer side of the sun visor faces the external interactive object. The sun visor reaches the target position after flipping outward. As an example, the sun visor can be parallel to the windshield at the target position, and the display surface of the display screen is at the same tilt angle as the windshield. This avoids reflections or blind spots caused by angle deviation, and makes it easier for interactive objects in different positions, such as pedestrians in front, oncoming vehicles, and non-motorized vehicles on the side, to capture the displayed content.

[0040] In this embodiment of the application, the displayed information can be divided into warning information, collaborative information, guidance information, status notification information, etc., according to the function of the displayed content.

[0041] In this embodiment of the application, the external interaction object may include other vehicles, pedestrians, or other external objects that may cause driving interference with the vehicle or require information exchange.

[0042] In this application embodiment, the displayed content may be in the form of icons, text, dynamic animations, color warnings, or combinations thereof, and must meet the principles of being intuitive, easy to understand, and quick to identify. For example, a green human-shaped icon indicating safe pedestrian passage and a "passable" text sign.

[0043] In this embodiment, the in-vehicle system fuses and analyzes the collected vehicle status information and / or environmental information to generate display content. Simultaneously, the in-vehicle system automatically controls the sun visor's flipping mechanism (such as an electric pivot) to flip the sun visor, which was originally facing inwards to block sunlight, outwards to a preset angle. This ensures the outer display screen faces external objects (such as oncoming vehicles or pedestrians), preventing the display content from being ineffectively observed due to angle issues. The generated content is displayed in real-time on the display screen integrated on the outside of the sun visor, enabling direct information transmission between the vehicle and external objects.

[0044] In this embodiment of the application, when generating display content, if the vehicle's sun visor has been flipped outward, the display content is directly displayed through the display screen located on the outside of the sun visor.

[0045] This application breaks through the limitations of traditional vehicles that can only transmit information through lights and horns. It communicates directly with external interactive objects through visual content, improving the communication efficiency between vehicles and people, and making the interaction more precise and intuitive.

[0046] The method provided in this embodiment dynamically acquires vehicle status information and / or environmental information during vehicle operation, and generates targeted display content for external interaction based on this information. This content is then displayed to external interaction objects using a screen on the outside of the sun visor that can be flipped outwards, achieving proactive and precise information interaction between the vehicle and its external environment. By transforming the sun visor into an interactive carrier with display functionality, and ensuring the screen accurately faces the external interaction object through a flipping mechanism, the method solves the problem of traditional vehicles lacking an effective direct external information output channel. This allows the display content generated based on vehicle status information and / or environmental information to be intuitively perceived by the external interaction object. The display content is generated based on real-time acquired vehicle status and environmental information, ensuring the timeliness and relevance of information and reducing information asymmetry in complex traffic scenarios. This interaction method expands the dimensions of vehicle information transmission, no longer limited to traditional methods such as lights and horns. Through visualized display content (such as intent prompts and warning information), it improves the accuracy and user-friendliness of information transmission, helping to reduce the risk of traffic accidents and improve road traffic efficiency.

[0047] In one optional implementation, S102 generates display content based on vehicle status information and / or environmental information, specifically including: S1021: Determine the vehicle's operating status based on the vehicle's status information.

[0048] In this application embodiment, the operating state includes at least one of the following: intention to decelerate, intention to accelerate, intention to drive at a constant speed, intention to turn, intention to park out, intention to park in, intention to overtake by using another lane, intention to go straight, intention to pull over, or intention to give way.

[0049] In this embodiment of the application, the vehicle's operating status can be determined by performing multi-dimensional fusion analysis, logical judgment, and intent deduction on the dynamic operating parameters and operation command information in the vehicle status information.

[0050] For example, when a positive acceleration is detected and there is no deceleration-related operation command, it is determined as an intention to accelerate. When the real-time vehicle speed remains stable (fluctuation range less than or equal to 5 km / h), the acceleration is close to 0, and there are no steering or lane-changing operations, it is determined as an intention to drive at a constant speed. When a steering angle greater than a preset threshold (e.g., 15°) is detected and the corresponding side steering signal is triggered, it is determined as a steering intention. When the gear is detected to be switched to reverse and the vehicle is in a parking lot scenario, it is determined as a parking exit or parking entry intention; a small forward movement of the vehicle speed indicates a parking exit intention, and a small reverse movement of the vehicle speed indicates a parking entry intention. When the brake pedal travel is detected to be greater than a preset value (e.g., 1 / 3 of the pedal travel) or the braking intensity is detected to be greater than a preset threshold, and there is no acceleration operation, it is determined as an intention to decelerate. When the driver triggers a lane-changing signal, and the acceleration is positive and the real-time vehicle speed is higher than that of vehicles in adjacent lanes, it is determined as an intention to overtake by using the adjacent lane. When the vehicle is traveling in a straight line (steering angle fluctuation range less than or equal to a preset value), and there are no lane-changing or steering commands, it is determined as a straight-going intention. When a vehicle is detected approaching the edge of the road (based on position sensor data), its speed gradually decreases, and braking continues, it is determined to be an intention to pull over. When the accelerator pedal is released, the brake is lightly applied (braking intensity less than a preset threshold), and the vehicle is at an intersection or in front of a pedestrian crossing, it is determined to be an intention to yield.

[0051] The embodiments of this application determine the vehicle's operating status based on the vehicle's status information. This process can achieve accurate identification of various operating statuses through parameter threshold setting, operation command matching, and scenario-assisted verification (combined with some environmental information), ensuring that the determination of the operating status is highly consistent with the actual vehicle operation.

[0052] S1022: Determine the factors affecting vehicle operation based on environmental information.

[0053] In this application embodiment, the influencing factors include at least one of the following: the external interaction object, the behavioral intention of the external interaction object, or the characteristics of the road environment.

[0054] This application embodiment determines the influencing factors affecting vehicle driving by performing layered analysis, dynamic correlation, and intent deduction of relevant information of external interactive objects and road environment in the environmental information surrounding the vehicle. As an example, the specific implementation of determining the influencing factors affecting vehicle driving based on environmental information is as follows: behavioral intent deduction is performed based on relevant information of external interactive objects. For example, when a pedestrian is detected moving towards the vehicle's driving path / the pedestrian makes a waving gesture towards the vehicle (such as palm facing the vehicle, arm swinging up and down or left and right) / the distance to the vehicle continues to decrease, and the pedestrian is in a zebra crossing or intersection area, it is determined that the pedestrian intends to cross the road. When other vehicles change their turning angle, trigger their corresponding turn signals, and move closer to the vehicle's lane, it is determined that the pedestrian intends to change lanes. When an oncoming vehicle's speed is significantly higher than the current road speed limit and encroaches on the vehicle's driving lane, it is determined that the pedestrian intends to drive in the wrong lane, thus clarifying the key influencing factor of the behavioral intent of the external interactive objects. At the same time, relevant information about the road environment is integrated and analyzed, and road types, road structures, traffic signs and markings are combined and classified to obtain the influencing factor of road environment characteristics, such as narrow road passing scenarios, curve passing scenarios, and parking lot entry scenarios.

[0055] S1023: Generate display content based on operating status and / or influencing factors.

[0056] In this embodiment of the application, a mapping relationship between the display content corresponding to different operating states and / or influencing factors can be pre-set, and the specific generated display content can be determined based on the mapping relationship.

[0057] The method provided in this embodiment can determine the specific operating states of a vehicle, such as deceleration and steering, through vehicle status information, and can determine the influencing factors affecting vehicle driving through environmental information, such as external interactive objects, the behavioral intentions of external interactive objects, or road environment characteristics. Display content can be generated through operating states and / or influencing factors, enabling external interactive objects to fully understand vehicle behavior and thus make more accurate responses, significantly improving the integrity of information transmission and decision support effect in complex traffic scenarios.

[0058] In this application, oncoming vehicles and pedestrians are the main external interaction objects. The following explanation uses oncoming vehicles and pedestrians as examples to illustrate the specific implementation of S1023 generating display content based on operating status and / or influencing factors.

[0059] In one optional implementation, when the external interaction object includes oncoming vehicles, display content is generated based on the operating status and / or influencing factors, including: Sa1: When an oncoming vehicle intends to slow down or yield, and the road environment features indicate that the current situation is a narrow road meeting scenario or a curve passage scenario, generate display content representing the oncoming vehicle's intention to slow down or yield.

[0060] As an example, the display indicating that an oncoming vehicle intends to slow down or give way may include bold black text such as "The other party is giving way, thank you for giving way," or text such as "Current road width allows for two-way traffic" when an oncoming vehicle hesitates.

[0061] Sa2: When an oncoming vehicle intends to speed or obstruct the flow of traffic, a prompt will be generated to remind the oncoming vehicle to slow down or give way. The oncoming vehicle's intention to yield, speed, or obstruct the flow of traffic are considered behavioral intentions of the oncoming vehicle.

[0062] As an example, the displayed content prompting oncoming vehicles to slow down or give way could be text such as "Oncoming vehicle is speeding, please slow down and pass" or "Oncoming vehicle is blocking the lane, please give way."

[0063] Sa3: When a vehicle intends to slow down or yield, and the road environment indicates that it is currently in a narrow road meeting scenario or a curve passing scenario, generate display content that represents the vehicle's intention to slow down or yield.

[0064] As an example, the display indicating that a vehicle intends to slow down or give way could be text such as "We are giving way, please proceed".

[0065] In this embodiment, when two vehicles, both equipped with displays on the outer side of their sun visors, meet, they can display greeting messages such as "Hello". They can also display expressions of driving intentions during assisted / automatic driving processes, such as: turning left / parking / overtaking / pushing over / yielding, etc.

[0066] The method provided in this embodiment targets oncoming vehicles as the interactive object, combining their behavioral intentions with special scenarios such as narrow roads and curves to generate adapted display content. It can accurately identify benign intentions such as slowing down and yielding, as well as risky intentions such as speeding and lane obstruction, and then combine this with road environment characteristics to determine the danger of the scenario, ultimately generating differentiated display content. When vehicles meet on narrow roads, clearly conveying the yielding intentions of both parties can avoid road congestion caused by hesitation about who should go first. Timely warnings of dangerous intentions can force unsafe behaviors of oncoming vehicles, reducing the incidence of oncoming collisions from the source, while improving traffic order and efficiency in special road sections.

[0067] In one optional implementation, when the external interactive object includes a pedestrian, the display content is generated based on the operating status and / or influencing factors, including: Sb1: When a pedestrian intends to cross the road and a vehicle intends to slow down or yield, generate display content indicating that the pedestrian can safely cross. The pedestrian's intention to cross the road is a behavioral intent of the external interactive object.

[0068] As an example, the display indicating that it is safe for pedestrians to cross could be the text "Vehicles slow down, please cross safely" or a green pedestrian sign.

[0069] Sb2: When the vehicle has at least one of the following intentions: accelerating, maintaining a constant speed, turning, parking out, parking in, overtaking, going straight, or parking on the side of the road, generate a display message to remind pedestrians to pay attention and avoid the vehicle.

[0070] As an example, the display message to alert pedestrians could be, "Vehicle traveling straight at 60 km / h, please give way." For instance, this message could be generated when a pedestrian is detected approaching a vehicle, carrying items in both hands, and the vehicle is attempting to pull over.

[0071] The method provided in this embodiment generates a display indicating safe passage when a pedestrian intends to cross and a vehicle is preparing to yield, resolving pedestrian hesitation caused by uncertainty about whether the vehicle will slow down. When a vehicle is accelerating, turning, or otherwise potentially threatening to pedestrians, it proactively issues a yielding warning, mitigating the risk of pedestrians being inattentive. Compared to traditional horn warnings, this method is more inclusive (e.g., effective for hearing-impaired individuals) and can significantly reduce the probability of conflicts at pedestrian-vehicle intersections, especially in densely populated areas such as schools and commercial districts, significantly improving pedestrian safety when crossing the street.

[0072] In an optional implementation, S1023 generates display content based on the operating status and / or influencing factors, and further includes: When the road environment parameters in the road environment features meet the warning conditions for environmental risks, a display message is generated to alert external interactive objects to the corresponding environmental risks. Road environment parameters include at least one of the following: precipitation parameters, wind speed parameters, visibility parameters, road surface friction coefficient parameters, or ambient light intensity parameters.

[0073] In this embodiment of the application, when the road environment features a charging parking space or a parking space, and the vehicle intends to park there, a display message is generated to indicate that the vehicle is about to enter the charging parking space or parking space.

[0074] In this embodiment of the application, corresponding environmental risk warning conditions can be set for different road environment parameters. For example, the environmental risk warning condition corresponding to the precipitation parameter is that when the precipitation in 1 hour is greater than or equal to 15 mm, or the precipitation in 10 minutes suddenly increases to greater than or equal to 8 mm, it is determined that the risk warning condition of slippery road surface caused by heavy rain is met, and the display content "Slippery road due to heavy rain, slow down" is generated.

[0075] The method provided in this embodiment monitors road environmental parameters such as precipitation and visibility in real time. When these parameters meet the warning conditions for environmental risks, it automatically generates corresponding environmental risk alerts. This transforms abstract parameter data into intuitive visual information, overcoming the limitations of traditional environmental warnings that rely on fixed roadside signs or broadcasts, and enabling real-time risk transmission in mobile scenarios. For example, during a sudden downpour, vehicle displays can immediately alert surrounding vehicles and pedestrians to be aware of slippery conditions, helping them adjust their speed and mode of travel in time, effectively reducing the incidence of traffic accidents caused by sudden environmental changes.

[0076] In an optional implementation, S1023 generates display content based on the operating status and / or influencing factors, and further includes: When the road environment features a parking lot sign and the vehicle intends to park out or park in, display content including guide arrows that align with the direction of the sign is generated.

[0077] The method provided in this embodiment combines the static environmental feature of parking lot directional landmarks with the dynamic intention of vehicles to park / exit, generating directional guide arrows. First, the direction indicated by the landmarks is identified, then matched with the vehicle's current parking intention, ensuring that the arrows reflect both the landmark specifications and the real-time movement trend of the vehicle. Especially in large parking lots or dimly lit environments, the intuitive arrow display helps surrounding vehicles and pedestrians anticipate vehicle trajectories, reducing collisions and congestion, and improving overall parking lot efficiency and safety.

[0078] In one optional implementation, when the vehicle is an operational vehicle and the vehicle status information also includes operational status, generating display content based on the vehicle status information and / or environmental information further includes: Generate display content representing the operational status based on the operational status.

[0079] In this embodiment, operational vehicles may include: emergency rescue vehicles, road construction vehicles, sanitation vehicles (water trucks, sweepers), municipal maintenance vehicles, public transport vehicles, logistics delivery vehicles, ambulances, fire trucks, and other special vehicles and dedicated vehicles that need to perform specific operational or work tasks on roads. Operational vehicles may also include taxis. As an example, the operational status of an emergency rescue vehicle may include: road rescue in progress, vehicle breakdown rescue in progress, emergency repair standby, etc. The corresponding display content may be "Road rescue in progress / vehicle breakdown rescue in progress / emergency repair standby, please detour." The operational status of a road construction vehicle may include: road surface demolition in progress, road paving in progress, construction area warning in progress, mobile construction, etc. The operational status of a sanitation vehicle may include: watering in progress, road sweeping in progress, garbage collection in progress, curb washing in progress, etc. The operational status of a municipal maintenance vehicle may include: greening pruning in progress, pipeline repair in progress, street light maintenance in progress, etc. The operational status of public buses can include: picking up and dropping off passengers at stops, temporarily stopping and waiting, operating on a designated route, and stopped for assistance due to a breakdown. The operational status of logistics delivery vehicles can include: temporarily unloading goods at the roadside, delivering goods within an industrial park, and waiting to load or unload goods. The operational status of ambulances can include: urgently transporting patients, performing emergency rescue missions, and returning empty. The operational status of fire trucks can include: performing firefighting missions, en route to emergency rescue, and conducting on-site security operations. The operational status of taxis can include: empty and carrying passengers.

[0080] The method provided in this embodiment transforms the operational status of vehicles into visual display content, taking into account their unique characteristics. Differentiated information is customized based on different operational statuses. This allows surrounding vehicles and pedestrians to quickly understand the operational needs of the vehicles. When construction vehicles are operating, it can guide other vehicles to detour in advance; when buses are stopping, it can remind pedestrians to wait in an orderly manner. This ensures the safe and efficient operation of the vehicles while minimizing interference with normal traffic flow, achieving coordinated passage between operational vehicles and other vehicles.

[0081] Figure 2 This is a flowchart of a display control method for another vehicle according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps: S201: During vehicle operation, acquire vehicle status information and / or environmental information surrounding the vehicle. For details, please refer to the description of S101 above; further details will not be provided here.

[0082] S202: Generate display content based on vehicle status information and / or environmental information, and trigger the vehicle's sun visor to flip outward, displaying the content on a display screen located on the outside of the sun visor. For details, please refer to the relevant description of S102 above, and will not be elaborated further here.

[0083] S203: Detect changes in vehicle status information and / or environmental information.

[0084] In this embodiment, after displaying the content on a screen located on the outside of the sun visor, changes in vehicle status information and / or environmental information are detected. Changes in vehicle status information may include changes in operating state from deceleration to acceleration, changes in operating commands from steering to straight driving, and dynamic operating parameters exceeding preset thresholds. Changes in environmental information may indicate changes in the type of external interactive object, changes in object behavior intent, updates to road environment features, and changes in the compliance status of road environment parameters.

[0085] S204: Determine the duration of the displayed content based on the changes, or whether to update the displayed content.

[0086] In this embodiment, the duration of the displayed content can be determined based on the changes, and whether to update the displayed content can be determined based on the changes. In this embodiment, the duration or whether to update the displayed content can be preset for different changes.

[0087] As an example, the specific implementation of determining the duration of the displayed content, or whether to update the displayed content, based on changes is as follows: A baseline duration for different initial displayed content can be preset, such as a 5-second baseline duration for pedestrian crossing prompts and a 10-second baseline duration for environmental risk warnings. This is then dynamically determined based on changes detected by Sc1: If a core change in vehicle status or environmental information is detected (e.g., the operating state changes from yielding to accelerating, the external interaction object changes from a pedestrian to an oncoming vehicle, or the road environmental feature changes from a straight road to a curve), or the triggering condition corresponding to the original displayed content has disappeared (e.g., the pedestrian has completed crossing), then it is directly determined that the displayed content needs to be updated, and the duration of the original displayed content is terminated. If no core change in information is detected, but the external interaction object has not responded (e.g., an oncoming vehicle has not slowed down according to the warning, or a pedestrian is still hesitating to cross), then the baseline duration is extended for a period of time, such as 2-5 seconds, to ensure sufficient information delivery. If no change in vehicle status and / or environmental information is detected, and the external interaction object has responded effectively (e.g., a pedestrian begins to cross, or an oncoming vehicle slows down to avoid them), then the baseline duration remains unchanged.

[0088] S205: If it is determined that the display content needs to be updated, the display content is regenerated and displayed on the display screen.

[0089] S206: If it is determined that the displayed content will not be updated, the display screen will be turned off after the duration is reached.

[0090] In this embodiment, if it is determined that the display content will not be updated, and the outward rotation of the vehicle's sun visor is triggered by the display content, then after the duration of the display content is reached, the sun visor is triggered to rotate inward to reset to its initial state. Simultaneously, the display screen is turned off to save vehicle energy, or the display screen is kept in a low-power standby state. If vehicle status information and / or environmental information are subsequently detected to meet the display triggering conditions again, the display screen can be quickly woken up. If it is determined that the display content will not be updated, and the outward rotation of the vehicle's sun visor is triggered by the occupants' sun shading needs (the sun visor has already rotated outward before the display content is generated), then after the duration of the display content is reached, the sun visor is not triggered to rotate inward to reset to its initial state; the display screen is directly turned off to save vehicle energy.

[0091] The method provided in this embodiment establishes a dynamic monitoring mechanism for vehicle status and environmental information, continuously tracking changes in both to determine the update of displayed content or the duration of display. This overcomes the information lag problem that may occur with static displays. For example, when a vehicle changes from decelerating to accelerating, the display can instantly switch content to avoid misleading others. Extending the display time during sudden environmental changes ensures effective information transmission, keeping external vehicle interactions always up-to-date and further improving the accuracy and safety of the interaction.

[0092] It should be noted that the contents not described in detail in this application specification are common knowledge to those skilled in the art.

[0093] This embodiment also provides a vehicle display control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0094] This embodiment provides a vehicle display control device, such as... Figure 3 As shown, it includes: The first processing module 301 is used to acquire vehicle status information and / or environmental information around the vehicle during vehicle operation.

[0095] The second processing module 302 is used to generate display content based on vehicle status information and / or environmental information, and trigger the vehicle's sun visor to flip outward, displaying the content through a display screen located on the outside of the sun visor. The display content is the interaction between the vehicle and external objects around the vehicle. After the sun visor flips outward, the display screen on the outside of the sun visor faces the external objects.

[0096] In one optional implementation, the second processing module 302 includes: The first processing unit is used to determine the vehicle's operating state based on the vehicle's status information. The operating state includes at least one of the following: intention to decelerate, intention to accelerate, intention to maintain a constant speed, intention to turn, intention to park out, intention to park in, intention to overtake by using another lane, intention to go straight, intention to pull over, or intention to yield.

[0097] The second processing unit is used to determine the influencing factors affecting vehicle driving based on environmental information. These influencing factors include at least one of the following: external interaction objects, the behavioral intentions of the external interaction objects, or road environmental characteristics.

[0098] The third processing unit is used to generate display content based on the operating status and / or influencing factors.

[0100] When an oncoming vehicle intends to speed or obstruct the flow of traffic, a prompt will be generated to remind the oncoming vehicle to slow down or give way. The oncoming vehicle's intention to yield, speed, or obstruct the flow of traffic are considered behavioral intentions of the oncoming vehicle.

[0101] When a vehicle intends to slow down or yield, and the road environment indicates that it is currently in a narrow road meeting scenario or a curve passage scenario, display content representing the vehicle's intention to slow down or yield is generated.

[0102] In one optional implementation, when the external interaction object includes a pedestrian, the third processing unit is specifically configured to generate display content indicating that the pedestrian can safely cross the road when the pedestrian intends to cross and the vehicle intends to slow down or yield. Here, the pedestrian's intention to cross the road is considered a behavioral intent of the external interaction object.

[0103] When a vehicle has at least one of the following intentions: to accelerate, to maintain a constant speed, to turn, to park out, to park in, to overtake by using another lane, to go straight, or to pull over, a display message will be generated to remind pedestrians to be careful and avoid the vehicle.

[0104] In one optional implementation, the third processing unit is further configured to generate display content prompting external interactive objects to pay attention to the corresponding environmental risk when the road environment parameters in the road environment features meet the warning conditions for environmental risk. The road environment parameters include at least one of the following: precipitation parameters, wind speed parameters, visibility parameters, road surface friction coefficient parameters, or ambient light intensity parameters.

[0105] In one alternative implementation, the third processing unit is further configured to generate display content including guide arrows consistent with the direction of the landmark when the road environment features a parking lot direction landmark and the vehicle has the intention to park out or park in.

[0106] In an optional implementation, when the vehicle is an operational vehicle and the vehicle status information also includes operational status, the third processing unit is further configured to generate display content representing the operational status based on the operational status.

[0107] In one alternative implementation, the vehicle's display control device further includes a third processing module.

[0108] The third processing module is used to detect changes in vehicle status information and / or environmental information after the content is displayed on the screen located on the outside of the sun visor.

[0109] Determine the duration of the displayed content based on the changes, or whether to update the displayed content.

[0110] If it is determined that the display content needs to be updated, the display content is regenerated and displayed on the screen.

[0111] If you determine that you will not update the displayed content, turn off the display after the time limit has been reached.
