Description

Technical Field

[0001] This invention relates to the field of vehicle safety technology, specifically to a method, system, electronic device, and storage medium for manual intervention control of electric seat belts. Background Technology

[0002] Currently, the function of electric seat belts is based on the active safety system's judgment of the vehicle's status. When the vehicle is in emergency braking, AEB (Autonomous Emergency Braking) activation, or other situations, the electric seat belts are pre-tensioned to reduce occupant displacement during vehicle instability and improve occupant injury during a collision.

[0003] However, the active control program design of electric seat belts still leaves many unaddressed scenarios that occupants need, such as: 1. Scenarios not considered in the initial program settings; 2. Scenarios with complex operating conditions where the electric seat belt is not actively responded to or has an extremely high response threshold to avoid discomfort to occupants due to its responsiveness, such as aggressive driving or off-road conditions; 3. Dangerous scenarios that the driver or occupant anticipates but have not yet occurred. Therefore, for these scenarios, the driver or passenger can manually activate the electric seat belt pretensioning to protect occupant safety while also meeting their psychological needs. At the same time, when the electric seat belt is executing a fixed program, the pretension force cannot be adjusted according to individual needs, which may lead to complaints about comfort.

[0004] Chinese patent "Electric Seatbelt Control Method, Device, Electronic Equipment, and Storage Medium," publication number CN115593351A, publication date January 13, 2023, discloses an electric seatbelt control method applied to a domain controller.

[0053] The technical solutions (including preferred technical solutions) of the present invention will be further described in detail below with reference to the accompanying drawings and by way of listing some optional embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0054] Example 1

[0055] See Figure 1 The present invention provides an electric seat belt manual intervention control system, including: a body controller 1, a manual switch 2, a seat belt main controller 3, and a motor 4.

[0056] The body controller 1 is used to identify various operating conditions of the vehicle, such as emergency braking and AEB activation, and sends corresponding control signals to the seat belt master controller 3. In this embodiment, the body controller 1 can be the vehicle's electronic control unit (ECU) or body control module (BCM), which can monitor various status parameters of the vehicle in real time, such as vehicle speed, acceleration, and steering angle, and determine the current operating condition of the vehicle based on these parameters.

[0057] Manual switch 2 is an adjustable button that can be pressed, rotated, or pushed. Specifically, manual switch 2 can be designed similarly to a radio switch, allowing the manual control mode to be turned on or off by pressing, and the preload force to be adjusted by rotating or pushing. It is typically installed in a location easily accessible to the driver or passenger. Manual switch 2 can send both on / off and adjustment signals.

[0058] The seat belt main controller 3 is the core control unit of the system. It is responsible for receiving signals from the body controller 1 and the manual switch 2, making judgments and controlling according to the preset logic, and sending corresponding control commands to the motor 4.

[0059] The seatbelt master controller 3 is electrically connected to the body controller 1 and the manual switch 2. It receives signals from the body controller 1 and control commands from the manual switch 2, and generates corresponding control signals based on the received signals and commands. The seatbelt master controller 3 includes an active control module and a manual control module. The active control module selects the appropriate PWM pulse control program based on the signals sent by the body controller 1, controlling the motor 4 to perform corresponding actions. For example, when the body controller 1 detects an emergency braking situation, the active control module selects the appropriate PWM pulse control program to control the motor 4 to perform a secondary pretensioning action. The manual control module controls the motor 4 to perform corresponding actions based on the control commands from the manual switch 2. For example, when the driver or passenger presses the manual switch 2, the manual control module controls the motor 4 to perform a primary pretensioning action; when the driver or passenger rotates or pushes the manual switch 2, the manual control module controls the motor 4 to adjust the pretensioning force.

[0060] Motor 4 is electrically connected to seat belt main controller 3 and is responsible for executing control commands issued by seat belt main controller 3 to drive the electric seat belt to perform corresponding actions. In this embodiment, the actions that motor 4 can perform include automatic winding, gap elimination, vibration reminder, primary pretensioning, and secondary pretensioning.

[0061] The working principle of the manual intervention control system for the electric seat belt in this embodiment is as follows:

[0062] I. Active Control Mode:

[0063] Once the body controller 1 identifies the corresponding operating condition, it sends a signal to the seatbelt main controller 3. Based on the received body signal, the seatbelt main controller 3 selects the appropriate PWM pulse control program to control the motor 4 to perform the corresponding actions. Specifically, this includes:

[0064] (1) Automatic retraction: When the seat belt buckle is released, motor 4 drives the seat belt to retract;

[0065] (2) Gap elimination: When the vehicle starts, the motor 4 slightly tightens the seat belt to eliminate the gap between the occupant and the seat belt;

[0066] (3) Vibration alert: In the event of a vehicle collision or lane departure, the seat belt will twitch to alert the occupant.

[0067] (4) Level 1 pretensioning: In scenarios such as emergency lane changes and high-speed cornering that may cause the human body to slightly deviate from its normal sitting posture, motor 4 moderately tightens the seat belt to reduce the amount of movement of the occupant's body. At this time, the tension of the seat belt is approximately 100-200N;

[0068] (5) Secondary pretensioning: In dangerous situations such as emergency braking and rollover, the electric seat belt quickly pulls the occupant back to a normal sitting position. At this time, the tension of the seat belt is about 300 to 400 N.

[0069] II. Manual Control Mode:

[0070] (1) Entering manual control mode: After pressing manual switch 2, the manual control circuit is turned on and the system enters manual control mode;

[0071] (2) Performing Level 1 Pretensioning: After entering the manual control mode, the seat belt main controller first controls motor 4 to perform the Level 1 pretensioning function;

[0072] (3) Adjusting the pretension force: By manually adjusting the forward or reverse adjustment switch, the main controller 3 of the seat belt controls the motor 4 to rotate forward or reverse, thereby driving the seat belt to retract or release, thus adjusting the pretension force;

[0073] (4) Exit manual control mode: Press the manual switch 2 again to disconnect the manual control circuit. The seat belt main controller 3 controls the motor 4 to restore the seat belt to its original state, and the system exits the manual control mode.

[0074] The electric seatbelt manual intervention control system in this embodiment introduces a manual switch 2 and a manual control mode, allowing the driver or passenger to actively control the pretension state and pretension force of the electric seatbelt according to their own needs. This design not only compensates for the shortcomings of automatic control in certain scenarios but also meets the personalized needs of occupants, greatly improving the practicality and flexibility of the electric seatbelt. At the same time, this system retains the original automatic control function, achieving an organic combination of automatic and manual control.

[0075] Example 2

[0076] See Figure 2 This invention provides a method for manual intervention control of an electric seatbelt, comprising: receiving a control signal for manual switching; determining whether to enter a manual intervention mode based on the control signal; if entering the manual intervention mode, determining the current state of the electric seatbelt; and controlling the electric seatbelt to perform corresponding actions based on the current state of the electric seatbelt and the control signal. This method can be executed by the electric seatbelt manual intervention control system in Embodiment 1. The specific steps are as follows:

[0077] Step S201: Receive the control signal from the manual switch.

[0078] Specifically, when the user presses manual switch 2, the system receives a control signal. This control signal can be a level signal or a pulse signal, used to indicate that the system enters manual control intervention mode.

[0079] Step S202: Determine whether to enter the manual control intervention mode based on the control signal.

[0080] After receiving a control signal, the seatbelt main controller 3 will determine whether the signal meets the conditions for entering the manual control intervention mode. For example, it can determine whether the duration of the signal exceeds a preset threshold, or whether the amplitude of the signal reaches a preset level.

[0081] Step S203: If the manual control intervention mode is entered, determine the current status of the electric seat belt.

[0082] Upon entering manual intervention mode, the system first needs to understand the current status of the electric seatbelt. In this embodiment, the status includes: unpretensioned, primary pretensioned, secondary pretensioned, and vibration alert status.

[0083] Step S204: Based on the current state of the electric seat belt and the control signal, control the electric seat belt to perform corresponding actions.

[0084] Depending on the current status of the power seatbelt and the received control signals, the system will perform different actions. These may include the following:

[0085] (1) If the electric seat belt is currently not pretensioned, then perform the first pretensioning action.

[0086] (2) If the electric seat belt is already in the first level of pretension, the pretension force can be increased or decreased according to the user's adjustment signal.

[0087] (3) If the electric seat belt is currently in the secondary pretension state or vibration warning state, then keep the current state unchanged.

[0088] In addition, this method may also include the following optional steps:

[0089] Step S205: In manual control intervention mode, receive adjustment signals from manual switches.

[0090] Users can adjust the preload by rotating or pushing manual switch 2. The system receives this adjustment signal for subsequent preload adjustments.

[0091] Step S206: Determine whether the electric seat belt is in the secondary pretension state.

[0092] If the electric seat belt is in the second pretension state, it usually means that the vehicle is in a high-risk state, and manual adjustment of the pretension force is not allowed at this time.

[0093] Step S207: If not, determine whether the electric seat belt is in vibration alert mode.

[0094] If the power seatbelt is in vibration alert mode, manual adjustment of the pretension is not allowed, so as not to interfere with the system's safety alert function.

[0095] Step S208: If the electric seat belt is not in vibration alert mode, control the motor 4 to rotate forward or reverse according to the adjustment signal to adjust the pretension of the electric seat belt.

[0096] The user is only allowed to adjust the pretension when the power seatbelt is neither in the secondary pretension state nor in the vibration alert state. The system will control the motor to rotate forward or backward based on the received adjustment signal, thereby increasing or decreasing the pretension.

[0097] Step S209: In manual control intervention mode, receive input signals from the Body Control Module (BCM).

[0098] Even in manual control intervention mode, the system will continue to monitor signals from the Body Control Module (BCM) to ensure timely response in emergency situations.

[0099] Step S210: If the input signal indicates to perform a vibration reminder, then control the electric seat belt to perform a vibration reminder action.

[0100] When the BCM sends a vibration alert signal, the vibration alert action will be executed immediately, regardless of the current state of the electric seat belt.

[0101] Step S211: If the input signal indicates that secondary pretensioning should be performed, the electric seat belt is controlled to perform secondary pretensioning action and exit the manual control intervention mode.

[0102] When the BCM issues a level 2 pretensioning signal, the system will immediately execute the level 2 pretensioning action and automatically exit the manual control intervention mode to ensure that the system can fully respond to the vehicle's emergency situation.

[0103] Step S212: If the input signal indicates that the first level of pretensioning should be performed, determine whether the electric seat belt is currently in the first level of pretensioning state. If not, control the electric seat belt to perform the first level of pretensioning action.

[0104] When the BCM sends a Level 1 pretensioning signal, the system first determines whether the power seatbelt is already in Level 1 pretensioning. If it is not in Level 1 pretensioning, the Level 1 pretensioning action is executed.

[0105] Step S213: Receive the exit signal from the manual switch.

[0106] Users can signal to exit the manual control intervention mode by pressing the manual switch 2 again.

[0107] Step S214: Control the electric seat belt to return to the state before entering the manual control intervention mode.

[0108] The system records the status of the electric seatbelt before entering manual intervention mode and restores it to that status upon exiting.

[0109] Step S215: Exit manual control intervention mode.

[0110] The system exits the manual control intervention mode and returns to the normal automatic control state.

[0111] The electric seatbelt manual intervention control method provided in this embodiment introduces a manual control intervention mode, allowing drivers or passengers to actively control the pretension state and pretension force of the electric seatbelt according to actual needs. Simultaneously, this method retains the ability to respond to signals from the Body Control Module (BCM), ensuring timely execution of necessary safety measures in emergency situations. This design satisfies users' personalized needs while ensuring the system's safety and reliability, significantly improving the practicality and flexibility of electric seatbelts.
