[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The vehicle anti-pinch method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the vehicle 100 may include a body processor 102 and a structure controller 104. When the body processor 102 receives a closing instruction sent by the structure controller 104, it determines the vehicle electric component corresponding to the control of the structure controller 104 according to the closing instruction; the closing instruction is used to control the vehicle electric component to perform a closing operation; when the body processor 102 detects the corresponding bioelectric signal of the vehicle electric component, it sends a rejection instruction to the structure controller 104 to instruct the structure controller 104 to control the vehicle electric component to stop closing; the bioelectric signal is a signal detected by a capacitive sensor set at a target position of the vehicle electric component; the target position is a position in the vehicle where there is a risk of the user being pinched.

[0034] The body processor 102 can be used to manage and control the body functions of the vehicle. Specifically, the body processor 102 can interact with the structure controller 104 for instructions, and obtain the bioelectric signals of the corresponding vehicle electric components according to the received instructions, and instruct the structure controller 104 to start and stop the vehicle electric components according to the bioelectric signals.

[0035] The structure controller 104 may refer to a control module for controlling the vehicle's electric components, which is responsible for managing and executing the opening and closing operations of the vehicle's electric components. The structure controller 104 may directly send a closing instruction to the vehicle's electric components to control the vehicle's electric components to perform the closing operation; it may also send a closing instruction to the body processor 102 so that the body processor 102 determines the vehicle's electric components that the structure controller corresponds to. At the same time, the structure controller 104 may immediately interrupt the closing process of the vehicle's electric components after receiving a rejection instruction sent by the body processor 102. Different vehicle electric components correspond to different structure controllers 104.

[0036] In an exemplary embodiment, Figure 2 As shown, a vehicle anti-pinch method is provided, and the method is applied to Figure 1The following is an example of the body processor in Figure 1.

[0037] Step S202: upon receiving a shutdown instruction sent by the structure controller, determining the vehicle electric component to be controlled by the structure controller according to the shutdown instruction.

[0038] The vehicle electric components may be components that are opened and closed by an electric system or external force, such as doors, windows or sunroofs, etc. The vehicle electric components may cause a risk of pinching and injury to people inside or outside the vehicle during the closing process.

[0039] The shutdown instruction is used to control the vehicle's electric components to perform a shutdown operation.

[0040] In a specific implementation, the structure controller may send a shutdown instruction to the vehicle electric component, and the vehicle electric component may perform a shutdown operation; at the same time, the structure controller may send a shutdown instruction to the body controller, so that the body controller determines the vehicle electric component that the structure controller controls. During the process of the vehicle electric component performing the shutdown operation, the body controller may detect whether there is a corresponding bioelectric signal in the vehicle electric component, and if so, send a rejection instruction to the structure controller, and the structure controller may control the vehicle electric component to stop shutting down.

[0041] As an example, the structural controller can determine that the vehicle's electric components are in the closing process by monitoring the closing angle of the vehicle's electric components. For example, the current opening and closing angle or position is detected in real time through a position sensor or an angle sensor. If the angle gradually decreases, it is judged to be in the closing process.

[0042] As another example, the structural controller may detect a manual closing operation through a sensor and determine that a user is pushing an electric component of the vehicle by hand, for example, by detecting an external force applied by a user through a pressure sensor and inferring that the electric component is in a manual closing process.

[0043] As another example, the structural controller can determine that the vehicle's electric components are in the process of shutting down by detecting an electronically controlled shutdown instruction sent by a terminal, or by detecting an electronically controlled shutdown instruction triggered by a shutdown control on an on-board screen or a physical button on the vehicle.

[0044] In a specific implementation, the body processor may store the corresponding control relationship between the structure controller and the vehicle's electric components. When the body processor receives a shutdown command, it may determine which structure controller sent the shutdown command. Therefore, the body processor may determine the vehicle's electric components that are correspondingly controlled by the structure controller based on the corresponding control relationship.

[0045] Step S204, when the bioelectric signal corresponding to the vehicle electric component is detected, a rejection instruction is sent to the structure controller to instruct the structure controller to control the vehicle electric component to stop shutting down.

[0046] The bioelectric signal is a signal detected by a capacitive sensor disposed at a target position of an electric component of the vehicle.

[0047] In a specific implementation, the bioelectric signal may be an electrical signal emitted by a living being and detected by a capacitive sensor disposed on an electric component of the vehicle. The detection of the bioelectric signal may be used to confirm whether there is a living being near the electric component of the vehicle, so as to identify the risk of pinching in advance.

[0048] Among them, the capacitive sensor is a sensing device that can be used to detect changes in the electric field. When a biological body appears nearby, its electric field will change slightly and trigger the sensor to respond, thereby confirming that the corresponding bioelectric signals of the vehicle's electric components have been detected.

[0049] Optionally, the bioelectric signal may also be a signal detected by a combination of a capacitive sensor, a vehicle-mounted camera, and a vehicle-mounted radar.

[0050] The target position is a position in the vehicle where there is a risk of the user being pinched. For example, the target position may be a door edge, a window top edge, a sunroof front edge, a trunk edge, and the like.

[0051] In the specific implementation, when the body processor detects the corresponding bioelectric signal of the vehicle's electric components, it can quickly transmit the rejection command to the structure controller through the vehicle's internal communication network (such as the CAN bus); after receiving the rejection command, the structure controller can immediately control the vehicle's electric components to stop shutting down, reduce response delays, and ensure that the shutdown operation of the vehicle's electric components can be stopped in time. The priority of the rejection command can be higher than other operation commands to ensure that the shutdown operation is interrupted immediately.

[0052] In the above-mentioned anti-pinch method for the vehicle, when receiving a closing instruction sent by the structure controller, the vehicle electric component corresponding to the control of the structure controller is determined according to the closing instruction, and the closing instruction is sent by the structure controller when it detects that the vehicle electric component is in the closing process; when detecting the corresponding bioelectric signal of the vehicle electric component, a rejection instruction is sent to the structure controller to instruct the structure controller to control the vehicle electric component to stop closing, and the bioelectric signal is a signal detected by a capacitive sensor set at a target position of the vehicle electric component, and the target position is a position in the vehicle where there is a risk of the user being pinched. By installing a capacitive sensor at a high-risk position of the vehicle electric component, and detecting the bioelectric signal in real time during the closing process of the vehicle electric component through the capacitive sensor, and immediately sending a rejection instruction when the corresponding bioelectric signal is detected, instructing the structure controller to stop the closing operation, the potential risk is perceived in advance before the biological body is contacted or squeezed, and the response lag is avoided, thereby improving the sensitivity and reliability of the vehicle anti-pinch and comprehensively improving the safety of the vehicle occupants.

[0053] In another embodiment, the vehicle electric components include at least one of an electric front hood, an electric sunroof, an electric door, an electric trunk, an electric window glass, an electric storage box, an electric energy charging cover, and an electric telescopic door handle.

[0054] In a specific implementation, the range of types of vehicle electric components can be expanded to include all components in the vehicle that are equipped with electric operation functions and have potential user pinching risk conditions.

[0055] Among them, the electric front hood can be a vehicle engine hood that is opened and closed by an electric mechanism or manually, and is used to inspect or maintain the engine; the electric sunroof can be a roof window that is opened and closed by electric or manual control to improve ventilation and lighting in the vehicle; the electric door can be a door that is opened and closed by electric or manual control; the electric trunk can be a trunk cover that is controlled by an electric device or manually; the electric window glass can be an electric lifting window glass operated by a button, which is used to adjust the air circulation in the vehicle; the electric storage box can be a storage space in the vehicle that is opened and closed by electric or manual control; the electric energy charging cover can be a charging port cover that is electrically or manually controlled to protect the charging port of the electric vehicle; the electric retractable door handle can be a door handle that pops out or retracts automatically.

[0056] In a specific implementation, capacitive sensors are provided at target positions of these vehicle electric components. Optionally, the target position may be a frame edge, an opening edge, etc. of the above-mentioned vehicle electric components, or may also be an edge of a movable component in the vehicle electric components.

[0057] The anti-pinch method of this embodiment is applicable to a variety of vehicle electric components, and can effectively prevent users from being pinched due to closing components in various scenarios, thereby improving the intelligence and safety of vehicle anti-pinch.

[0058] In another embodiment, when a bioelectric signal corresponding to an electric component of the vehicle is detected, a rejection instruction is sent to a structural controller, including: obtaining capacitance data collected by a capacitor sheet on an edge of a movable component arranged in the electric component of the vehicle; and when a bioelectric signal is detected in the electric component of the vehicle based on the capacitance data, a rejection instruction is sent to the structural controller.

[0059] Among them, the capacitor sheet is a capacitive sensor composed of two layers of conductive material with an insulating medium in between. When a biological body (such as a finger, head, etc.) approaches or touches the capacitor sheet, it will cause a change in the electric field distribution, resulting in a change in the capacitance value. These changes in capacitance values ​​are the capacitance data collected by the capacitor sheet. By detecting the changes in these capacitance values, the presence of the biological body can be identified, so that the corresponding bioelectric signals of the vehicle's electric components can be confirmed. The capacitor sheet is sensitive to changes in the electric field and can collect signals from biological bodies approaching or touching the edge in real time. Its high precision enables the system to quickly determine potential pinching situations and respond quickly without waiting for actual collisions or squeezes to occur.

[0060] Among them, the movable parts in the vehicle electric parts can refer to movable parts that can be switched from one state (such as closed) to another state (such as open). For example, if the vehicle electric part is an electric window glass, the electric window glass can include components such as a window frame, a sealing strip, a guide rail, and glass. The glass can be moved by a lifting mechanism, so the glass can refer to the movable parts of the electric window glass; for another example, if the vehicle electric part is an electric storage box, the electric storage box can include components such as a box cover and a lock system. The box cover can be opened and closed, so the box cover can refer to the movable parts of the electric storage box.

[0061] In practical applications, the movable parts of the vehicle's electric components refer to the "cover" or "door" part of the component that can be opened or closed. These movable parts are usually the main moving parts of the component. For example, the movable part of the electric door refers to the door itself, the movable part of the electric trunk refers to the trunk cover, and the movable part of the electric sunroof refers to the movable glass part.

[0062] In a specific implementation, the target position for setting the capacitive sensor may refer to an edge of a movable component in an electric component of a vehicle.

[0063] The edge of the movable component may refer to the edge area of ​​the movable component, that is, the edge portion where the movable component is connected to the vehicle body or may be closed. The edge of the movable component is the area that the user may touch or approach when closing or opening the electric component. The presence of the biological body is detected by the capacitor sheet, so as to respond to the anti-pinch demand in time. For example, the edge of the movable component may refer to the glass edge of the window glass and the edge of the lid of the electric storage box. Exemplarily, the capacitor sheet arranged at the edge of the movable component may cover the key areas on the closing path of the movable component in the vehicle electric component, such as the upper and lower edges of the movable component, the front and rear edges of the movable component, the corner position of the movable component, the inner and outer sides of the movable component, etc., so that no matter from which angle the biological body approaches, the capacitor sheet can capture the bioelectric signal, thereby providing comprehensive, efficient and sensitive anti-pinch protection during the closing process of the movable component of the vehicle electric component.

[0064] In another embodiment, when the bioelectric signal corresponding to the vehicle electric component is detected, it also includes: sending a reverse movement instruction to the structure controller to instruct the structure controller to control the movable component in the vehicle electric component to move in reverse.

[0065] Among them, the reverse movement instruction is a control signal sent by the body processor to the structure controller after the risk of pinching is detected, which is used to instruct the structure controller to control the electric component to move in the reverse direction and away from possible living organisms.

[0066] When the body processor detects the corresponding bioelectric signals of the vehicle's electric components, it generates a reverse motion instruction and sends it to the structure controller through the vehicle's internal communication network (such as the CAN bus); after receiving the reverse motion instruction, the structure controller controls the movable parts in the vehicle's electric components to move in the opposite direction. For example, if the window is in the process of rising and closing, the window will be controlled to fall after receiving the reverse motion instruction to open the window.

[0067] In one embodiment, the closer the organism is to the capacitive sensor, the greater the capacitance change of the capacitive sensor, and the stronger the signal strength of the collected bioelectric signal. A higher signal strength indicates that the organism is very close to the electric component, so the risk level is higher; a low signal strength may indicate that the organism is farther away and the risk is lower. Therefore, the body processor sends a reverse motion instruction to the structure controller to instruct the structure controller to control the movable component in the vehicle electric component to move in reverse, which may include:

[0068] The body processor determines the corresponding pinch risk level based on the signal strength of the detected bioelectric signal; wherein, the greater the signal strength, the higher the pinch risk level; determines the amplitude of the reverse movement based on the pinch risk level; wherein, the higher the pinch risk level, the greater the amplitude of the movement; generates a reverse movement instruction based on the amplitude of the movement; sends the reverse movement instruction to the structure controller to instruct the structure controller to control the reverse movement of the movable parts in the vehicle's electric parts according to the amplitude of the movement.

[0069] In one embodiment, the rate of change of the bioelectric signal reflects the speed at which the organism approaches the electric component, and a fast approach generally means a higher risk of pinching. A fast-changing signal indicates that the organism approaches quickly, and the level of pinching risk is higher; a slowly changing signal indicates that the approach speed is slow, and the level of pinching risk is lower. Therefore, the body processor sends a reverse motion instruction to the structure controller to instruct the structure controller to control the movable component in the vehicle electric component to move in reverse, which may include:

[0070] The body processor determines the corresponding pinch risk level based on the signal change rate of the detected bioelectric signal; wherein, the greater the signal change rate, the higher the pinch risk level; determines the amplitude of the reverse movement based on the pinch risk level; wherein, the higher the pinch risk level, the greater the amplitude of the movement; generates a reverse movement instruction based on the amplitude of the movement; sends the reverse movement instruction to the structure controller to instruct the structure controller to control the reverse movement of the movable parts in the vehicle's electric parts according to the amplitude of the movement.

[0071] In one embodiment, the body processor can also capture the environmental image of the vehicle's electric components through the vehicle-mounted camera and identify the organism in the environmental image when the corresponding bioelectric signal of the vehicle's electric components is detected; when the organism in the environmental image is the target organism, a reverse motion instruction is sent to the structure controller to instruct the structure controller to control the movable parts in the vehicle's electric components to move in reverse; the target organism includes children or the elderly.

[0072] The technical solution of this embodiment sends a reverse motion instruction to the structural controller so that the movable parts in the vehicle's electric parts can move in the opposite direction, ensuring that no harm is caused to the user before the potential risk of pinching is eliminated, thereby improving the safety and timeliness of vehicle anti-pinch.

[0073] In another embodiment, when the bioelectric signals corresponding to the electric components of the vehicle are detected, it also includes: controlling the vehicle screen to display a prompt screen; the prompt screen is used to prompt that there is a living thing at the target location.

[0074] Among them, the vehicle-mounted screen can be a display screen installed inside the vehicle, used to display navigation, entertainment information, vehicle status, etc.

[0075] In a specific implementation, the prompt screen may include a warning message for indicating the presence of a living organism at the target location. Optionally, the prompt screen may include a warning icon and a prompt text, and the prompt text may include a description of the specific component location to help the user quickly locate the risk area. For example, the prompt text may be "Attention: A living organism is detected near the left front door. Please confirm safety before operating."

[0076] Optionally, the prompt screen may also include a confirmation virtual button or a close virtual button, allowing the user to manually close the prompt, or these virtual buttons may automatically disappear after the body processor detects that the risk of pinching has been eliminated.

[0077] The technical solution of this embodiment, the prompt screen can effectively remind the user to pay attention to the potential risk of pinching, thereby enhancing the safety of vehicle use.

[0078] In another embodiment, when the bioelectric signal corresponding to the vehicle's electric components is detected, it also includes: controlling the vehicle audio to play a prompt voice; the prompt voice is used to indicate the presence of a living thing at the target location.

[0079] Among them, the vehicle audio system can be an audio playback system inside the vehicle, which is used to play navigation prompts, music, voice commands, etc. The prompt voice includes audio information used to prompt the presence of organisms at the target location. Optionally, the prompt voice may include warning sound effects and warning sentences. The prompt voice may include a description of the specific location of components to help users quickly locate risk areas. For example, the voice content of the prompt voice may be "Attention: A living organism has been detected near the left front door. Please confirm that it is safe before operating."

[0080] The technical solution of this embodiment enhances the user's safety awareness through intuitive voice prompts, effectively reduces the risk of pinching, and improves the safety of the vehicle and user experience.

[0081] In another embodiment, the closing instruction is sent by the structure controller when at least one of an electronically controlled closing operation for the vehicle electric component and a manual closing operation for the vehicle electric component is detected.

[0082] Among them, the electronically controlled shutdown operation may include operations triggered by physical buttons in the vehicle or soft switches on the vehicle screen, and may also include operations triggered by commands sent by the remote control key or terminal connected to the vehicle.

[0083] The manual closing operation may include an operation in which a user directly pushes or pulls a movable component to close the movable component (such as manually closing a door).

[0084] When the structure controller detects at least one of an electronically controlled shutdown operation for a vehicle electric component and a manual shutdown operation for a vehicle electric component, the structure controller sends a shutdown instruction to the body processor to indicate that the corresponding vehicle electric component is being shut down.

[0085] The technical solution of this embodiment is to identify the electric control and manual closing operations through the structural controller, and issue a closing command to start anti-pinch monitoring, so that the vehicle can ensure user safety in various closing methods and effectively reduce the risk of pinching.

[0086] In order to facilitate the understanding of those skilled in the art, Figure 3 A logic diagram of an anti-pinch method for a vehicle is exemplarily provided. Specifically, in step 01, there is a risk of potential users being pinched when these vehicle electric components are closed; in step 02, capacitor sheets are arranged at the edges of the movable components in each vehicle electric component, which are the parts that users touch most frequently; in step 03, the bioelectric signals collected by the capacitor sheets are sent to the body processor; in step 04, if the body processor determines that no bioelectric signals are detected near the movable components, then the structure controller is allowed to continue to execute the instruction to electrically control the movable components to close; in step 05, the structure controller closes the movable components in the corresponding vehicle electric components; in step 06, at this moment, someone manipulates the vehicle electric components and closes the corresponding movable components, and the body processor determines that bioelectric signals are detected at the edges of the movable components; in step 07, the structure controller corresponding to the vehicle electric component sends the closing instruction to the body processor for review; in step 08, the body processor confirms that the capacitor sheet corresponding to the vehicle electric component detects the bioelectric signal; in step 09, the body processor rejects the closing instruction of the structure controller; in step 10, the screen controller and the audio controller receive the instructions sent by the body processor; in step 11, the screen and the audio simultaneously prompt the presence of a biological body.
