Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle driving safety protection technology, and in particular to a method, system and vehicle for protecting driver safety in a vehicle collision. Background Technology
[0002] Frontal collisions are a very common type of traffic accident. The driver's side has a steering mechanism and steering wheel, thus limiting the space for movement. In the event of a collision, the industry has designed a crumple zone steering mechanism that collapses under stress. When the driver's space is zero, the steering mechanism collapses inwards, and the steering wheel and steering gear move inwards, providing the driver with more room to maneuver.
[0003] As cars become increasingly intelligent, many combination switches are integrated into the sides of the steering wheel and steering gear cover. These combination switches obstruct the movement of the steering gear and steering wheel into the vehicle, restricting the driver's movement space and endangering the driver's life safety.
[0004] On the other hand, whether the driver's seat is adjusted to the optimal position is a crucial factor affecting driver injury. The optimal position requires sufficient displacement while ensuring the driver's airbag and seatbelt provide the best protection. Current technology lacks the ability to automatically recognize the driver's body shape and adjust the seat to the optimal protection position during a collision; these issues urgently need to be addressed.

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.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0056] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0057] Please refer to the accompanying drawings. This invention provides a technical solution: a method for protecting driver safety during a vehicle collision, comprising the following steps:
[0058] S102. Collect the driver's weight information, the current position of the driver's seat, and the vehicle speed information;
[0059] S104. The airbag controller receives the weight information and vehicle speed information, and generates the target position information of the driver's seat.
[0060] The airbag control unit (ACU) is a passive safety device and a crucial component for protecting the driver during a vehicle collision. When a collision causes a sudden change in vehicle speed, collision sensors detect the collision and transmit the collision signal to the ACU. The ACU analyzes the collision information corresponding to the collision signal to determine the severity of the collision and then decides whether to issue a seatbelt deployment command. This causes the seatbelts to tighten according to the seatbelt pretensioning command, generating pretensioning force to reduce the severity of injury to the occupants.
[0061] Optionally, the system receives the current seat position signal and pressure signal of the current power-on cycle from the seat rail sensor and seat pressure sensor, respectively; determines the current seat position information based on the current seat position signal, and determines the weight information based on the pressure signal. Optionally, a safe energy threshold is set when the driver is subjected to an impact; the impact energy of the driver is determined based on the weight information and vehicle speed information at the time of the collision; the target seat position is determined based on the protective force applied by the vehicle to protect the driver, the safe energy threshold, and the impact energy, wherein the protective force includes the pretensioning force of the seat belt and the cushioning force of the airbag.
[0062] Understandably, according to E = 1 / 2mv 2=FL, where E is the energy value of the driver's impact during the collision, m is the driver's weight, and v is the vehicle's speed at the time of the collision. Therefore, when a car collides, E is constant. The driver's safe energy threshold E0 can be set based on the energy impact that the driver can withstand during the impact, according to the simulation analysis during the collision. The airbag protection energy value E1, which is offset by the airbag's buffering force, is determined according to the design parameters of the airbag mechanism. The seat belt pretension force F, which acts on the driver within the distance L between the target position of the seat and the steering wheel, is the seat belt protection energy value E2, which is offset by the driver's seat belt pretension force. Based on the driver's weight information and the vehicle speed information at the time of the collision, the energy value E of the driver's impact during the collision can be obtained, E = E0 + E1 + E2 = E0 + E1 + FL. Therefore, the optimal position of the target seat is when the distance between the driver's seat and the steering wheel is L. The distance L between the driver's seat and the steering wheel varies according to the driver's weight m.
[0063] Specifically, based on the variation of the distance L between the driver's seat and the steering wheel according to the driver's weight m and the statistical analysis of experimental data, the relationship between the driver's weight and the optimal collision position can be optionally set as follows:
[0064] If the driver's weight is ≤60kg, the optimal collision position is the front 1 / 4 position of the seat travel; if the driver's weight is ≤90kg, the optimal collision position is the front 1 / 2 position of the seat travel; if the driver's weight is >90kg, the optimal collision position is the front 1 / 2 + 30mm position of the seat travel. Here, the seat travel is the maximum distance the seat can be adjusted forward and backward on the seat rail, and the optimal collision position is the target position of the seat.
[0065] S106. The airbag controller determines the first displacement information of the driver's seat moving from the current seat position to the target seat position based on the current seat position information and the target seat position information.
[0066] Specifically, based on the determined target seat position and the current seat position, the first displacement information of the required movement between the current seat position and the target seat position is obtained.
[0067] Optionally, a first displacement threshold for the seat is set. When the airbag controller determines that the first displacement information is greater than the first displacement threshold, it generates second displacement information for the steering gear active collapse. When the airbag controller receives a collision signal sent by a collision sensor, it generates an active steering gear collapse command based on the collision signal and the second displacement information. The airbag controller sends the active steering gear collapse command to the active steering gear collapse drive mechanism, so that the active steering gear collapse drive mechanism drives the steering gear from its current position to a target position according to the active steering gear collapse command. The airbag controller generates a seat movement command based on the collision signal and the first displacement information, so that the seat drive mechanism drives the driver's seat from its current position to the target position according to the magnitude of the first displacement threshold, wherein the first displacement value is equal to the sum of the second displacement value and the first displacement threshold.
[0068] Understandably, the greater the distance the seat moves during a collision, the greater the pressure of the seatbelt pretension on the driver's chest. Setting a first displacement threshold within a reasonable range can effectively alleviate the pressure of the pretension on the driver's chest. At the same time, the compensating active collapsible steering gear keeps the distance between the steering wheel and the driver's seat equal to the distance between the steering gear and the target position of the seat when the steering gear is not collapsible. Optionally, the driver's weight can be correlated with the first displacement threshold. As the driver's weight increases or decreases, the first displacement threshold increases or decreases accordingly.
[0069] S108. When the airbag controller receives a collision signal sent by the collision sensor, the airbag controller generates a seat movement command based on the collision signal and the first displacement information.
[0070] S110, The airbag controller sends the seat movement command to the seat drive mechanism, so that the seat drive mechanism drives the driver's seat from the current seat position to the target seat position according to the seat movement command.
[0071] In the above embodiments,
[0072] Optionally, when the airbag controller receives a collision signal from the collision sensor, it further includes:
[0073] When the airbag controller receives a collision signal from the collision sensor, the airbag controller generates an instrument panel retraction command based on the collision signal.
[0074] The airbag controller sends the dashboard retraction command to the dashboard retraction drive mechanism, so that the dashboard retraction drive mechanism controls the dashboard to retract according to the dashboard retraction command.
[0075] In the above embodiments, as automobiles become increasingly intelligent, many combination switches are integrated on both sides of the steering wheel and steering gear cover. These combination switches create significant resistance during the retraction of the steering gear and steering wheel into the vehicle, reducing the distance L between the driver's seat and the steering wheel. This restricts the driver's movement space, greatly increasing the impact force on the driver and endangering their life. Optionally, the dashboard retraction drive mechanism of the present invention is flush with the dashboard body during normal vehicle operation, ensuring the vehicle's aesthetics. After a collision, it automatically retracts inward with the dashboard body, providing the driver with more movement space and reducing driver injury.
[0076] On the other hand, whether the driver's seat is adjusted to the optimal position is a crucial factor affecting driver injury. The optimal position requires sufficient displacement (L) while ensuring the driver's airbag and seatbelt provide optimal protection. Current technology lacks the ability to automatically recognize the driver's body shape and adjust the seat to the optimal protection position during a collision.
