[0048] See Figure 1 The diagram shows a flowchart of a control method for a vehicle restraint system according to an embodiment of this application.

[0049] like Figure 1 As shown, according to a first aspect of the embodiments of this application, a control method for a vehicle restraint system is provided, including but not limited to steps S101 to S103:

[0050] Step S101. When a vehicle collision occurs, obtain the actual collision scenario and actual collision speed of the vehicle;

[0051] Step S102. Search the database for target constraint parameters that match the actual collision scenario and the actual collision speed. The database stores the correspondence between each collision scenario and each collision speed and each constraint parameter. The constraint parameters include at least one linearly adjustable parameter of a constraint component.

[0052] Step S103. Control the at least one constraint component to constrain and protect the occupants according to the target constraint parameters.

[0053] Based on the above disclosure, the embodiments of this application provide corresponding target constraint parameters for different collision scenarios and different collision speeds when a vehicle collision occurs, so that the vehicle restraint system can restrain and protect the occupants according to the target constraint parameters, thereby improving the vehicle's restraint and protection performance and enhancing the occupant experience.

[0054] In some embodiments, the control method of the vehicle restraint system in this application can be implemented by the vehicle's existing ECU (Electronic Control Unit) controller, which can be located inside the vehicle compartment.

[0055] In step S101, the collision speed refers to the relative speed between the object itself and the other object colliding with it at the time of the collision, i.e., the speed difference.

[0056] In some embodiments of step S101, when a collision occurs, the speed of other vehicles or objects colliding with the vehicle can be detected by a radar device installed on the vehicle body, and the speed of the vehicle can be detected by a speed sensor installed on the vehicle. The radar device sends the speed of other vehicles or objects to the ECU, and the speed sensor sends the speed of the vehicle to the ECU. The ECU calculates the speed difference between the speed of other vehicles or objects and the speed of the vehicle to obtain the actual collision speed.

[0057] In some embodiments of step S101, in order to detect whether a collision event has occurred, the embodiments of this application can detect whether a collision event has occurred by installing a collision detection sensor on the vehicle body. For example, the collision detection sensor can be installed at the front, rear, or side of the vehicle body to detect collision events that occur at the front, rear, or side of the vehicle. Similarly, when the collision detection sensor detects that a collision event has occurred, it sends a notification to the ECU so that the ECU is aware that a collision event has occurred.

[0058] In step S101, the collision scenario includes various scenarios in which a vehicle may collide, including but not limited to a vehicle hitting a rigid wall, a vehicle hitting a tree or utility pole, a vehicle colliding with another vehicle, a vehicle hitting a highway guardrail, etc., which will not be elaborated here.

[0059] In some embodiments of step S101, in order to better identify actual collision scenarios, the embodiments of this application can collect images of actual collision scenarios by installing cameras on the vehicle body. For example, the cameras can be distributed around the vehicle body and on the top of the vehicle body to collect images, so that the collision scenario can be identified according to existing image recognition algorithms.

[0060] It is understood that the radar device, speed sensor, collision detection sensor, and camera, etc., in the embodiments of this application can be connected to the ECU controller via wired connection or wireless connection, and no limitation is made here.

[0061] In some embodiments of step S102, the constraint component includes at least a steering column, and the linearly adjustable parameters include the steering column crushing force and the steering column crushing stroke. This application provides matching linearly adjustable parameters for the steering column, such as the steering column crushing force and the steering column crushing stroke, for different collision scenarios and different collision speeds. This allows the steering column to be crushed according to the corresponding crushing force and crushing stroke based on the actual collision situation, thereby providing a more suitable crash space for the occupants and improving occupant safety protection performance.

[0062] In some embodiments of step S102, the restraint assembly further includes an airbag and / or a seatbelt, and the linearly adjustable parameters include the airbag deployment time and / or the seatbelt tightening time. This application provides matching airbag deployment times and / or seatbelt tightening times for different collision scenarios and speeds, thereby controlling the airbag to deploy at corresponding times and / or controlling the seatbelt to tighten at corresponding times based on the actual collision situation, thus providing corresponding restraint protection for occupants and improving occupant experience.

[0063] In some embodiments of step S102, searching the database for target constraint parameters that match the actual collision scenario and the actual collision speed includes:

[0064] Search the database for a target collision scenario that matches the actual collision scenario, and a target collision speed that matches the actual collision speed;

[0065] Based on the correspondence, find the target constraint parameters corresponding to the target collision scenario and the target collision speed.

[0066] It is understood that the target collision scenario can be the same as the actual collision scenario, or it can be the scenario in the database that is closest to the actual collision scenario; similarly, the target collision speed can be the same as the actual collision speed, or it can be the speed in the database that is closest to the actual collision speed. The specific settings are based on the actual application requirements and are not limited here.

[0067] The database stores the correspondence between various collision scenarios and collision velocities and various constraint parameters. This correspondence can be achieved by storing a preset mapping table in the database, which records the correspondence between various collision scenarios and collision velocities and various constraint parameters.

[0068] The process of searching the database for target constraint parameters that match the actual collision scenario and the actual collision speed includes: searching for a target collision scenario that matches the actual collision scenario and a target collision speed that matches the actual collision speed; and searching for the target constraint parameters corresponding to the target collision scenario and the target collision speed in a preset mapping table.

[0069] The database storing the correspondence between various collision scenarios and collision velocities and various constraint parameters can also be configured as follows: the database stores a mapping function, which represents the functional relationship between various collision scenarios and collision velocities and various constraint parameters. By calling the mapping function, the constraint parameters corresponding to the collision scenarios and collision velocities can be calculated.

[0070] The process of searching the database for target constraint parameters that match the actual collision scenario and the actual collision speed includes: finding a target collision scenario that matches the actual collision scenario and a target collision speed that matches the actual collision speed; and calling a mapping function to calculate the target constraint parameters corresponding to the target collision scenario and the target collision speed.

[0071] In some embodiments of step S102, the process of establishing the correspondence between each collision scenario and each collision velocity and each constraint parameter is as follows:

[0072] For each collision scenario and each collision speed within a preset collision speed range, with the optimal occupant restraint performance as the optimization objective and the different constraint parameters of each restraint component as variables, an occupant restraint performance optimization model is constructed. The minimum speed of the preset collision speed range is the collision speed corresponding to the start of the vehicle restraint system.

[0073] The optimal solution of the occupant constraint performance optimization model is used as the constraint parameters corresponding to the current collision scenario and the current collision speed to establish the correspondence.

[0074] It should be noted that when establishing the correspondence, it is usually necessary to pre-calibrate and generate a set of constraint parameters that meet current specifications, i.e., the constraint parameters of the restraint system when a vehicle collides with a rigid wall. At this time, the specifications such as the size and material of the airbag and seat belt can be determined. Based on the determined specifications of the airbag and seat belt, the linear adjustable parameters of each restraint component in the restraint system are then calibrated, such as the airbag deployment time, the seat belt tightening time, the crushing force of the steering column, and the crushing stroke of the steering column.

[0075] It is understood that the minimum speed in the preset collision speed range is the collision speed corresponding to the activation of the vehicle restraint system, meaning that the vehicle restraint system is activated when the collision speed is greater than the minimum speed to restrain and protect the occupants.

[0076] It is understood that the preset collision speed range includes multiple collision speeds. For example, within the speed range from the minimum speed V0 to the maximum speed Vt, a collision speed is defined every n kilometers per hour. Similarly, within the collision speed range of 30 to 120, a collision speed is defined every 5 kilometers per hour or every 10 kilometers per hour. The maximum speed Vt refers to the maximum speed a vehicle can typically reach during a collision. For each collision scenario, the minimum and maximum collision speeds can be set according to the specific collision scenario; no limitation is made here.

[0077] The optimal occupant restraint performance refers to the ability to achieve the best protection for the occupants, i.e., minimize harm to the occupants, by using the corresponding restraint parameters under the current collision speed and collision scenario.

[0078] It is understandable that when establishing the correspondence between various collision scenarios and collision velocities and various constraint parameters, the occupant constraint performance optimization model can be solved using existing simulation software or experimental devices. The solution principle is the existing principle, which will not be elaborated here.

[0079] In some embodiments of step S103, controlling the at least one constraint component to constrain and protect the occupants according to the target constraint parameters includes:

[0080] The steering column is controlled to crush according to the target crushing force and target crushing stroke to provide the corresponding collision protection space for the occupants.

[0081] In some embodiments of step S103, controlling the at least one constraint component to constrain and protect the occupants according to the target constraint parameters includes:

[0082] Control the airbags to deploy at the target deployment time, and / or control the seat belts to tighten at the target tightening time to restrain and protect the occupants.

[0094] Step S303. Control the at least one constraint component to constrain and protect the occupants according to the target constraint parameters.
