Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, device, system, and vehicle for controlling a transparent A-pillar display. Background Technology

[0002] The A-pillar of a car is the connecting pillar between the roof and the front compartment on the left and right front sides. It is located between the engine compartment and the driver's compartment, above the left and right rearview mirrors. When the vehicle changes lanes or turns, it will obstruct part of the driver's view, creating a blind spot. The existence of this blind spot is a driving safety hazard. The emergence of transparent A-pillars can solve this problem, eliminating blind spots for the driver while driving, preventing the A-pillar from obstructing the driver's view, and reducing the probability of accidents.

[0003] In related technologies, a control switch is usually set on the vehicle's infotainment system, allowing users to choose to turn the transparent A-pillar display on or off; or to associate the blind spot image display with vehicle speed, so that the transparent A-pillar display remains on when the vehicle speed is below a preset speed threshold.

[0004] However, the existing control strategies are too simplistic, making it difficult for vehicles to achieve intelligent control of the transparent A-pillar. If the transparent A-pillar display screen remains in working mode when it is not needed, it will not only waste vehicle resources but may also distract the driver and affect driving safety.

[0076] 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, and 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.

[0077] It should be noted that with the development of the automotive industry, the level of vehicle intelligence is constantly improving, and intelligent driving systems have emerged to provide users with a convenient and technologically advanced driving experience. Intelligent driving systems employ a multi-sensor fusion solution and are equipped with a high-precision positioning module and an intelligent driving map module, enabling them to accurately and effectively perceive the vehicle's location and surrounding environmental information, thereby assisting users in end-to-end intelligent driving control.

[0078] The inventors of this application have discovered that current intelligent driving systems and transparent A-pillar control systems are relatively independent systems, and even suffer from hardware redundancy. For example, the blind spot images displayed on the transparent A-pillar screen are usually captured by cameras specifically installed on the A-pillars on the left and right sides of the vehicle. However, in the multi-sensor fusion scheme of the intelligent driving system, at least eight visible light cameras are typically installed in the four directions of the vehicle (front, rear, left, and right). The identifiable area includes both the near and far ends of the vehicle. Therefore, in terms of camera coverage area or scenario, the cameras provided by the intelligent driving system can effectively replace the cameras on the transparent A-pillar.

[0079] Traditional control strategies for transparent A-pillars are simplistic, with blind spot image display only linked to vehicle speed. When the vehicle speed is below a preset threshold, the transparent A-pillar display remains on, making it difficult for the vehicle to achieve intelligent control of the transparent A-pillar. If the transparent A-pillar display remains on even when it is not needed, it will not only waste vehicle resources but may also distract the driver and affect driving safety.

[0080] To address the problems existing in the aforementioned background technology, this application aims to provide a method for controlling a transparent A-pillar display in a vehicle. By reusing the intelligent driving system in conjunction with the current driving scenario of the vehicle, it is possible to achieve intelligent opening and closing of the transparent A-pillar display screen without increasing the vehicle's hardware costs. This avoids interference with the driver's attention caused by prolonged operation, thereby improving the overall vehicle resource utilization rate while enhancing the reliability and convenience of the transparent A-pillar function.

[0081] Reference Figure 1 This application illustrates a method for controlling the display of a transparent A-pillar in a vehicle, applicable to a transparent A-pillar controller. The method may include the following steps:

[0082] S101: Determine the current driving scenario of the vehicle based on the vehicle's location information and / or environmental perception information.

[0083] It should be noted that prior to S101, drivers could actively control the vehicle to enter the transparent A-pillar intelligent control mode through the vehicle's infotainment system according to their own driving needs, so as to control the transparent A-pillar controller to execute the vehicle's transparent A-pillar display control method, thereby realizing the intelligent opening and closing of the transparent A-pillar display screen.

[0084] In this embodiment, the vehicle can be controlled to enter the transparent A-pillar intelligent control mode in multiple ways. For example, after the vehicle is started, the driver can control the vehicle to enter the transparent A-pillar intelligent control mode by directly issuing a voice command, triggering a pre-configured physical button, or triggering a virtual button on the display screen.

[0085] Specifically, after the driver activates the transparent A-pillar function by touching the transparent A-pillar control switch on the vehicle's infotainment display, they can further select whether to enter the transparent A-pillar intelligent control mode on the interactive interface provided on the display. After the user selects to activate the transparent A-pillar intelligent control mode, the vehicle controller responds to the driver's mode activation operation, controls the vehicle to enter the preset transparent A-pillar intelligent control mode, and sends an information acquisition command to the intelligent driving controller. The intelligent driving controller then responds to this information acquisition command, uses existing modules in the intelligent driving system to acquire the vehicle's location information and / or environmental perception information, and sends the location information and / or environmental perception information to the transparent A-pillar controller.

[0086] It should be noted that location information can be obtained through the high-precision positioning module of the intelligent driving system. Specifically, the high-precision positioning module can use GNSS (Global Navigation Satellite System) to determine the current location of the vehicle. Environmental perception information can be collected through the sensor module of the intelligent driving system. Specifically, the sensor module includes, but is not limited to, sensors such as lidar, cameras, millimeter-wave radar, and ultrasonic sensors, which collect environmental perception information around the vehicle in real time. Among them, environmental perception information can include different types of environmental images collected by different sensors.

[0087] In this embodiment, after receiving the location information and / or environmental perception information sent by the intelligent driving controller, the transparent A-pillar controller will determine the vehicle's current driving scenario based on the location information and / or environmental perception information. The driving scenario may include, but is not limited to, driving on various types of roads such as highways, urban expressways, urban roads, rural roads, or parking lots.

[0088] In practical implementation, when the vehicle has good signal, the current road type can be determined based on the vehicle's location information, thereby determining the vehicle's current driving scenario; or, when the vehicle is in an area with weak or no signal, environmental perception information can be input into a pre-trained scene recognition model to output the current driving scenario; or, in complex traffic sections where multiple driving scenarios may exist in the same location area, the scene recognition model can be used to assist in the judgment and determine the vehicle's actual current driving scenario from among the multiple driving scenarios.

[0089] S102: Determine the target control strategy corresponding to the current driving scenario.

[0090] It should be noted that the usage requirements for A-pillar displays vary depending on the driving scenario. For example, in driving scenarios such as highways, where vehicle speeds are typically higher and obstacles are fewer, the need for transparent A-pillar displays is usually less. In driving scenarios on urban roads, where vehicle speeds are typically lower and obstacles are more numerous, transparent A-pillar displays need to be activated more frequently to ensure driving safety.

[0091] In this embodiment, to meet the needs of intelligent opening and closing of the transparent A-pillar display screen under different driving scenarios, different control strategies are set for different driving scenarios. These control strategies are specifically designed for the transparent A-pillar display screen.

[0092] In this embodiment, the control strategy may include a first control strategy, a second control strategy, and a third control strategy for three common vehicle driving scenarios.

[0093] Specifically, when the current driving scenario is on a highway or urban expressway, the target control strategy is determined as the first control strategy, which is a control strategy for highway or urban expressway scenarios; or, when the current driving scenario is on urban or rural roads, the target control strategy is determined as the second control strategy, which is a control strategy for urban or rural roads scenarios; or, when the current driving scenario is in a parking lot, the target control strategy is determined as the third control strategy, which is a control strategy for parking lot scenarios.

[0094] S103: Control the transparent A-pillar display screen to open or close according to the target control strategy.

[0095] In this embodiment, different control strategies have different judgment logic for whether to turn on the transparent A-pillar display screen. That is, different conditions for turning on and off the display screen are set for different driving scenarios, thereby realizing the intelligent turning on and off of the transparent A-pillar display screen under different driving scenarios.

[0096] In one example, when the vehicle's transparent A-pillar intelligent control mode is activated, and the vehicle is driving on urban streets, the transparent A-pillar controller determines the target control strategy as the second control strategy. During the vehicle's journey, if a large number of obstacles are detected around the vehicle and the display screen activation conditions corresponding to the second control strategy are met, the transparent A-pillar display screen will automatically turn on and display the driver's blind spots on the transparent A-pillar display screen. As the vehicle continues to drive, from urban streets to urban expressways, the transparent A-pillar controller will switch the target control strategy from the second control strategy to the first control strategy. If a smaller number of obstacles are detected around the vehicle, the transparent A-pillar display screen will automatically turn off until the vehicle meets the display screen activation conditions corresponding to the first control strategy, and then the transparent A-pillar display screen will be turned on again.

[0097] Based on the reuse of the intelligent driving system, this application embodiment further clarifies and refines the switching logic of the transparent A-pillar display screen in combination with the vehicle's driving scenario. It can realize the intelligent opening and closing of the transparent A-pillar display screen in different driving scenarios, avoiding interference with the driver's attention due to prolonged opening. While improving the utilization rate of vehicle resources, it also enhances the reliability and convenience of the transparent A-pillar function.

[0098] In one feasible implementation, S103 may specifically include the following sub-steps:

[0099] S103-1: Determine the number of obstacles around the vehicle when the target control strategy is the first control strategy or the second control strategy;

[0100] In this embodiment, considering the scenario of the vehicle driving in a parking lot, both the first and second control strategies are designed for scenarios where the vehicle is driving on a road. In this case, the number of obstacles on the road is a key factor in determining whether to activate the transparent A-pillar display screen. Therefore, after determining whether the target control strategy is the first or second control strategy, the number of obstacles around the vehicle will be identified based on the environmental perception information collected by the intelligent driving system.

[0101] In this embodiment, obstacles include dynamic obstacles and static obstacles. Dynamic obstacles refer to objects whose position can change, such as pedestrians, motor vehicles and non-motor vehicles; static obstacles refer to objects whose position does not change, such as poles, water-filled barriers and roadblocks.

[0102] In practice, obstacles within a preset range can be identified as valid obstacles to reduce the computational load of the transparent A-pillar controller and improve the recognition speed.

[0103] S103-2: Control the opening or closing of the transparent A-pillar display screen based on the number of obstacles.

[0104] In this embodiment, by identifying the number of obstacles around the vehicle, it is possible to effectively determine whether there is a collision risk. Considering that the first control strategy is for highway or urban expressway conditions, while the second control strategy is for urban or rural road conditions, different display screen on and off conditions will be set for the first and second control strategies respectively, depending on the driving road.

[0105] Specifically, when the target control strategy is the first control strategy, that is, when the vehicle is detected to be traveling on a highway or urban expressway, S103-2 may include the following sub-steps:

[0106] S103-2-A1: When the number of obstacles is less than or equal to the first quantity threshold, control the transparent A-pillar display screen to turn off.

[0107] In this embodiment, the first quantity threshold can be set to 3. That is, when the number of obstacles detected is less than or equal to 3, it indicates that the collision risk of the vehicle is low. At this time, it is not necessary to turn on the transparent A-pillar display screen, or the already turned-on transparent A-pillar display screen can be turned off.

[0108] It should be noted that this implementation does not impose specific restrictions on the first quantity threshold, and users can customize the settings according to their own driving experience and driving needs.

[0109] In this embodiment, obstacle attributes can be determined, and different priorities and quantity thresholds can be set for obstacles with different attributes. For example, pedestrians can be set as the highest priority, and the transparent A-pillar display screen can be turned on when at least one pedestrian is detected around the vehicle.

[0110] S103-2-A2: When the number of obstacles exceeds a first threshold, obtain the vehicle's steering wheel angle and road information.

[0111] In this embodiment, when the number of obstacles detected exceeds the first threshold, it indicates that the vehicle has a certain risk of collision in the current driving scenario. At this time, it will be further determined whether the transparent A-pillar display needs to be turned on based on the steering wheel angle and road information.

[0112] It should be noted that the intelligent driving system can obtain the vehicle's map information through the intelligent driving map module, and based on the map information, obtain the road information ahead of the vehicle's path.

[0113] S103-2-A3: When the steering wheel angle is greater than the first turning angle threshold and the road information is a ramp section or a congested section, control the transparent A-pillar display screen to turn on.

[0114] In this embodiment, considering that the vehicle is usually traveling at high speed in the current driving scenario, if only the steering wheel angle is detected to be greater than the first angle threshold, it means that the driver is performing a normal lane change operation, and there is no need to turn on the transparent A-pillar display screen; if at the same time the vehicle is also detected to be on a ramp or a congested section of road, which is prone to traffic accidents, the transparent A-pillar display screen will be turned on to ensure the driving safety of the vehicle.

[0115] Specifically, when the target control strategy is the second control strategy, that is, when the vehicle is detected to be traveling on urban or rural roads, S103-2 may include the following sub-steps:

[0116] S103-2-B1: When the number of obstacles is less than or equal to the second quantity threshold, control the transparent A-pillar display to turn off.

[0117] In this embodiment, the second quantity threshold can be the same as or different from the first quantity threshold. Preferably, considering that the current driving scenario is on urban or rural roads, the road conditions are more complex and there are more dynamic obstacles compared to highways and urban expressways. Therefore, the second quantity threshold can be less than the first quantity threshold, such as being set to 2. That is, when the number of detected obstacles is less than or equal to 2, it indicates that the vehicle's collision risk is low. In this case, it is not necessary to turn on the transparent A-pillar display screen, or the already turned-on transparent A-pillar display screen can be turned off.

[0118] It should be noted that this implementation does not impose specific restrictions on the second quantity threshold, and users can customize the settings according to their own driving experience and driving needs.

[0119] S103-2-B2: When the number of obstacles exceeds the second quantity threshold, obtain the vehicle's steering wheel angle and / or road information.

[0120] In this embodiment, when the number of obstacles detected exceeds the second threshold, it indicates that the vehicle has a certain risk of collision in the current driving scenario. At this time, it will be further determined whether the transparent A-pillar display needs to be turned on based on the steering wheel angle and / or road information.

[0121] It should be noted that the intelligent driving system can obtain the vehicle's map information through its intelligent driving map module, and based on this map information, obtain road information ahead of the vehicle's path.

[0122] S103-2-B3: When the steering wheel angle is greater than the second turning angle threshold, and / or the road information is a left turn section, right turn section, U-turn section, or congested section, control the transparent A-pillar display screen to turn on.

[0123] In this embodiment, the second turning angle threshold can be the same as or different from the first turning angle threshold. Preferably, considering that the current driving scenario is on urban or rural roads, where vehicles are lower than on highways and urban expressways, drivers need to turn at a larger angle when changing lanes. Therefore, the second turning angle threshold can be set to be greater than the first turning angle threshold.

[0124] In this embodiment, considering that vehicles typically travel on various street roads in the current driving scenario, where road conditions are more complex and there are many dynamic obstacles such as pedestrians and non-motorized vehicles, as well as static obstacles such as poles and roadblocks, the vehicle is required to have higher driving safety. Therefore, when the driver is detected to be making a large-scale turning lane change operation; or when the road information in front of the vehicle is detected to be a left-turn section, right-turn section, U-turn section, or congested section; or when the vehicle is detected to be making a turning operation on a left-turn section, right-turn section, U-turn section, or congested section, the transparent A-pillar display screen will be activated to provide the driver with blind spot visibility and ensure vehicle driving safety.

[0125] In one feasible implementation, S103 may further include the following sub-steps:

[0126] S103-3: When the target control strategy is the third control strategy, control the transparent A-pillar display screen to open.

[0127] It should be noted that when a vehicle is driving in a parking lot, the vehicle's signal is usually weak or even non-existent, making it impossible to accurately obtain the vehicle's location information. In this case, a scene recognition model can be used to identify the environmental perception information collected by the sensor module to determine whether the vehicle is in the parking lot.

[0128] In this embodiment, considering that when a vehicle is driving in a parking lot, whether it is entering or exiting the parking lot or patrolling the parking lot, the driver's visibility is poor and the lane is narrow, which requires a high level of driving skills from the driver, in order to ensure the driving safety of the vehicle in the parking lot, when the target control strategy is determined to be the third control strategy, the transparent A-pillar display screen will be directly controlled to open, providing the driver with real-time images of the blind spot until the vehicle is turned off or leaves the parking lot.

[0129] In this embodiment, by reusing the intelligent driving system, the transparent A-pillar controller can, despite increased hardware costs, utilize the intelligent driving system to collect vehicle location information and / or environmental perception information, thereby recognizing the vehicle's current driving scenario and matching the target control strategy corresponding to the current driving scenario. This enables intelligent opening and closing of the transparent A-pillar display screen in various driving scenarios. Furthermore, since the intelligent driving camera can replace the transparent A-pillar camera, the vehicle's hardware costs can be further reduced, resolving the redundancy issue in hardware configuration between the intelligent driving system and the transparent A-pillar control system. This improves the overall vehicle resource utilization while enhancing the reliability and convenience of the transparent A-pillar function.

[0130] In one feasible implementation, the vehicle transparent A-pillar display control method may further include the following steps:

[0131] S201: When the vehicle enters the preset transparent A-pillar non-intelligent control mode, obtain the vehicle's current speed, current gear, and steering signal.

[0132] In this embodiment, after activating the transparent A-pillar function switch, the driver can either select the intelligent control mode via the interactive interface provided by the vehicle's infotainment system, or choose to enter a non-intelligent mode, i.e., the non-intelligent control mode. In this mode, the transparent A-pillar controller will no longer consider the vehicle's current driving scenario, but will instead control the intelligent opening and closing of the transparent A-pillar display screen according to fixed control logic.

[0133] S202: When the current vehicle speed is greater than or equal to the vehicle speed threshold, control the transparent A-pillar display to turn off.

[0134] In this embodiment, considering that there is usually no need for transparent A-pillars at medium to high vehicle speeds, the transparent A-pillar display screen will be turned off when the current vehicle speed is greater than or equal to a speed threshold; the speed threshold can be set to 20 km / h.

[0135] S203: When the current vehicle speed is less than the vehicle speed threshold and the turn signal is on, or when the current vehicle speed is less than the vehicle speed threshold and the current gear is reverse, control the transparent A-pillar display to open.

[0136] It should be noted that turn signals refer to information triggered by the driver through the turn lever or turn button, specifically including left turn signals and right turn signals. In other words, when the driver triggers a left turn signal or a right turn signal, the turn signal is confirmed to be in the active state.

[0137] In this embodiment, when the vehicle speed is below the threshold, the transparent A-pillar display screen can be automatically opened when the driver performs steering or reversing operations, providing the driver with a blind spot view and effectively avoiding collisions with obstacles.

[0138] In this embodiment, after the driver turns on the transparent A-pillar function switch, the driver can control the vehicle to enter the transparent A-pillar intelligent control mode or the transparent A-pillar non-intelligent control mode according to their own driving needs, so as to meet the different needs of drivers with different driving experience for the transparent A-pillar function, thereby effectively ensuring the driver's driving safety in various scenarios.

[0139] In one feasible implementation, after step S103, which controls the transparent A-pillar display to open according to the target control strategy, the vehicle transparent A-pillar display control method may further include the following steps:

[0140] S104: Obtain the raw blind spot image of the vehicle.

[0141] In this embodiment, the original blind spot image is formed by fusing images captured by multiple pre-set intelligent driving cameras.

[0142] It should be noted that the multiple intelligent driving cameras are part of the sensor module of the intelligent driving system. Specifically, the multiple intelligent driving cameras may include a left surround-view camera, a right surround-view camera, and two side cameras; the left surround-view camera can be located at the connection between the left A-pillar and the left front compartment, the right surround-view camera can be located at the connection between the right A-pillar and the right front compartment, and the two side cameras are located at the left and right doors of the vehicle, respectively.

[0143] S105: Based on the driver's line of sight information, the original blind spot image is cropped to obtain the target blind spot image.

[0144] In this embodiment, the original blind spot image contains image information of a large area in front of and to the sides of the vehicle. That is, the original blind spot image also includes the non-blind spot field of view that the driver can observe. Therefore, the original blind spot image needs to be cropped to retain only the target blind spot image that the driver cannot observe.

[0145] In its implementation, the transparent A-pillar controller can acquire the driver's gaze information through an in-vehicle camera, establish a local coordinate system, calculate the human eye's gaze attention vector in this local coordinate system, and use the coordinates of the human eye in the local coordinate system and the human eye's gaze attention vector as input to a pre-built neural network model. This neural network model calculates the cropping region of the original blind spot image, that is, it crops the original blind spot image to obtain the target blind spot image that the human eye is focused on.

[0146] S106: Use the target blind spot image as the target display content of the transparent A-pillar display screen.

[0147] In this embodiment, after determining the target blind spot image that the human eye is focused on, it can be displayed on the transparent A-pillar display screen. Preferably, the transparent A-pillar display screen can be a matte screen. Compared with a mirrored screen, a matte screen does not produce glare when the light is strong, which can effectively prevent light from reflecting into the human eye, causing glare to the driver, and affecting driving safety.

[0148] In this embodiment, multiple intelligent driving cameras can replace the original transparent A-pillar camera, which can not only reduce the vehicle's hardware costs, but also ensure that complete blind spot images are obtained, providing the driver with a good blind spot view and reducing the probability of accidents.
