[0002] In the existing technology, seat belts and airbags are the most effective passive safety measures for occupant protection in the event of a car collision. However, accident investigations have found that seat belts and airbags still have significant limitations in serious car accidents. Specifically, the steering wheel and airbag may not be able to properly support the driver's upper body, and may seriously trap the driver and make him unable to escape.

[0003] With the advancement of new technologies, especially chip computing power and image recognition technology, new thinking is being brought to active vehicle safety technology. Therefore, based on these new technologies, it is crucial to improve seat belts and airbags as the sole passive collision safety strategy, optimize the collision safety process, and enhance the personal safety of vehicle occupants, especially drivers, in vehicle accidents.

[0013] Furthermore, in the step of calculating a safe distance for the cockpit seat to move backward within the current cycle after determining that the safety of the occupant is not affected, the safe distance is calculated based on the weight information of the occupant.

[0014] Furthermore, when the vehicle has a head-on collision and the collision degree reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seat, the following step is also included: controlling the vehicle to start a general safety protection strategy.

[0020] Furthermore, the step of periodically calculating the safe distance for the cockpit seat to move backward, wherein the safe distance is determined based on the passenger status in the passenger compartment, further comprises the following steps:

[0021] When the vehicle is involved in a side collision and the collision degree reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seat, the cockpit seat is controlled to move backward to the safety distance calculated within the period when the collision occurs.

[0033] Figure 1 1 is a flowchart of a process according to an embodiment of the present invention. Figure 1 As shown, the vehicle includes a cockpit seat and a passenger compartment seat, the cockpit seat is configured to be movable forward and backward and allowed to move backward to interfere with the passenger compartment seat, and the collision safety protection method for the vehicle includes the following steps:

[0034] S1. Periodically calculate a safe distance for the cockpit seat to move backward. The safe distance is determined based on the status of the occupants in the passenger compartment.

[0035] S2. When a frontal collision occurs and the severity of the collision reaches a preset level, and the rearward movement of the cockpit seat does not affect the safety of the occupants in the passenger compartment seats, the cockpit seat is controlled to move rearward to the safety distance calculated within the collision period.

[0036] Specifically, the status of the occupants in the passenger compartment is periodically obtained, and the safe distance that the cockpit seat can move backward is calculated based on the status of the occupants in the passenger compartment. Then, when the vehicle collides head-on and the degree of collision reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seat, the cockpit seat is controlled to move backward to the safe distance calculated within the collision cycle.

[0037] Furthermore, if the rearward movement of the cockpit seat affects the safety of the occupants in the passenger compartment seats, the rearward movement of the cockpit seat is not controlled.

[0038] In this embodiment, the safety distance for the cockpit seat to move backward is periodically calculated, and the safety distance is determined according to the status of the occupants in the passenger compartment. When the vehicle collides head-on and the degree of collision reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seat, the cockpit seat is controlled to move backward to obtain the safety distance calculated during the collision period, thereby reducing personal injury to the driver during a car collision.

[0039] In a further embodiment, Figure 1 and Figure 2 As shown, after periodically calculating the safe distance for the cockpit seat to move backward, the following steps are also included:

[0040] S11. Obtain passenger information at the seat in the passenger compartment, where the passenger information includes whether there is a passenger, the passenger's weight, the passenger's location, and the passenger's posture in the seat in the passenger compartment.

[0041] S12. Determine, based on at least part of the occupant information, whether the cockpit seat will affect occupant safety when moving backward within the current cycle.

[0042] S13. After determining that the safety of the occupants is not affected, calculate the safe distance for the cockpit seat to move backward within the current cycle.

[0043] Specifically, first, the occupant information in the vehicle passenger compartment is obtained through the vehicle sensor device and the imaging device inside the vehicle to determine whether there are occupants in the passenger compartment. When there are no occupants in the passenger compartment, or when objects are placed on the passenger compartment seats, it is determined that the vehicle's cockpit seat will not cause harm to the occupants in the passenger compartment seats when it moves backward during a collision, and the cockpit seat can be moved back the maximum distance. If it is detected that there are occupants in the passenger compartment, it is necessary to further obtain the occupant information to determine the distance the cockpit seat should be moved back.

[0044] The posture and position of the occupant in the passenger compartment are captured using an imaging device to determine whether the occupant is sitting or reclining. If the occupant is reclining, the driver's seat is determined to be capable of moving backward without injuring the occupant in the passenger compartment seat, as the occupant does not interfere with the legroom between the cockpit and passenger compartment seats. Therefore, the driver's seat can be moved backward to its maximum distance in a collision. If the occupant is sitting, the driver's seat type is further determined. Different cockpit seat displacement distances are determined based on the occupant type. The cockpit seat is then controlled to move according to the displacement distances to protect the cockpit occupant.

[0045] In this embodiment, the passenger information in the passenger compartment is obtained to further determine whether the cockpit seat is moved rearward. When the cockpit seat meets the conditions for moving rearward, the cockpit seat is controlled to move rearward to protect the cockpit occupants. When the cockpit seat does not meet the conditions, the cockpit seat is not controlled to move rearward, thereby protecting the occupants in the passenger compartment.

[0046] In a further embodiment, when the occupant in the passenger compartment is in a sitting position, when controlling the cockpit seat to move backward, the distance of the movement needs to be determined based on the type of occupant. At this time, the occupant's weight is obtained through the sensor on the seat, and the occupant is divided into adults or children based on their different weights. When the weight exceeds a preset value, the occupant in the passenger compartment is identified as an adult. Due to the limitation of the adult's leg position, if the cockpit seat moves backward at this time, it will inevitably cause damage to the occupant in the passenger compartment. The cockpit seat is controlled not to move backward. At this time, the vehicle is controlled to enable a general safety protection strategy. In addition, if it is detected that an object is placed on the passenger compartment seat, it will not be divided according to the obtained weight. It should be pointed out that the general safety protection strategy is the vehicle's own collision protection strategy, which will not be elaborated here.

[0047] If the occupant's weight does not exceed the preset weight, the occupant is deemed to be a child. At this time, the cockpit seat is controlled to move backward a preset distance, thereby protecting the occupants in the cockpit and reducing the injuries to the cockpit occupants. It should be pointed out that the preset distance can be calibrated according to the vehicle type. The displacement distance is different for different vehicle types and can be calibrated according to actual conditions.

[0048] Specifically, data is first collected through the vehicle's internal and external detectors to determine whether the vehicle has collided and whether the rearward movement of the cockpit seat will affect the safety of the occupants in the passenger compartment. When the vehicle starts, the sensors inside the vehicle will work and make judgments. The internal sensors will continue to obtain occupant information in the passenger compartment to determine whether there are occupants in the passenger compartment and the occupant's position, posture, weight and other information, and then make a judgment based on the relevant information. This process occurs before the accident collision.

[0049] When the judgment is completed, two policy execution plans will be obtained:

[0050] If it is determined that the operation of the cockpit seat will not affect the safety of the occupants in the passenger compartment seats, the distance the cockpit seat is moved back is further determined based on the occupant information, thereby protecting the occupants in the cockpit seats.

[0051] If it is determined that the operation of the cockpit seat will affect the safety of the occupants in the passenger compartment seats, the cockpit seat will be controlled not to move backward, and basic protection strategies will be implemented, such as airbag operation, seat belt self-retraction and other basic vehicle protection measures, thereby achieving protection for the occupants in the passenger compartment seats.

[0052] In addition, it should be pointed out that in order to ensure the timeliness of collision safety protection, the judgment logic process needs to be as simple as possible and the computing power needs to be higher. Therefore, the response and processing time of the relevant judgment program needs to be within 100ms, so as to ensure that the protection strategy can respond in a timely manner.

[0053] In this embodiment, by dividing the occupants into different types and limiting the displacement distance according to the different types of occupants, the vehicle can protect both the occupants in the cockpit and the occupants in the passenger compartment when performing collision safety protection.

[0054] In one embodiment, Figure 3 As shown, the vehicle also includes a guide rail 2 for guiding the movement of the cockpit seat 1 and a protective member 3 arranged on the guide rail 2. The protective member 3 is located in front of and / or behind the cockpit seat 1. The protective member 3 is configured to have a storage state stored in the guide rail 2 and a deployment state in which it is deployed to prevent the cockpit seat from tipping over. When the protective member 3 is in the deployed state, it is connected to the cockpit seat 1. When the vehicle collides head-on and the degree of collision reaches a preset degree, and the cockpit seat 1 moves backward without affecting the safety of the occupants in the passenger compartment seats, the protective member 3 is controlled to be deployed from the storage state to the deployment state, and after the cockpit seat 1 moves to a preset safety distance, the protective member 3 is controlled to be stored from the deployment state to the storage state.

[0055] Specifically, when the vehicle collides head-on, the front protective member 3 pops up and moves along with the cockpit seat 1 in the opposite direction of the head-on collision. Its main purpose is to always fix the cockpit seat 1 in a safe and reliable moving state, while the rear protective member 3 retracts and moves along with it in the opposite direction of the head-on collision. Its main purpose is to determine that the cockpit seat 1 is in a fast-moving state, and quickly bounce back and fix it after the cockpit seat 1 reaches the designated position, thereby stabilizing the cockpit seat.

[0056] In this embodiment, protective members are provided at the front and rear ends of the cockpit seat, and the protective members pop up and move along with the cockpit seat when the cockpit seat moves backward, thereby preventing the cockpit seat from tipping over, further ensuring the stability of the cockpit seat movement, and improving the protection of the occupants on the cockpit seat.

[0057] In another embodiment, after the step of periodically calculating the safe distance for the cockpit seat to move backward and determining the safe distance based on the passenger status in the passenger compartment, the method further includes the following steps:

[0058] When the vehicle is involved in a side collision and the collision degree reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seats, the cockpit seat is controlled to move backward to a safe distance calculated within the period of the collision.

[0059] Specifically, the status of the occupants in the passenger compartment is periodically obtained, and the safe distance that the cockpit seat can move backward is calculated based on the status of the occupants in the passenger compartment. Then, when the vehicle has a side collision and the collision degree reaches a preset degree, and the cockpit seat does not affect the safety of the occupants in the passenger compartment seat when moving backward, the cockpit seat is controlled to move backward to the safe distance calculated within the collision cycle.

[0060] Furthermore, if the cockpit seat moves backward and affects the safety of the occupants in the passenger compartment seats, the cockpit seat is not controlled to move backward, but the vehicle is controlled to start the general safety protection strategy.

[0061] In this embodiment, the safety distance for the cockpit seat to move backward is periodically calculated, and the safety distance is determined according to the status of the occupants in the passenger compartment. When the vehicle has a side collision and the degree of collision reaches a preset degree, and the cockpit seat moves backward without affecting the safety of the occupants in the passenger compartment seat, the cockpit seat is controlled to move backward to obtain the safety distance calculated during the collision period, thereby reducing personal injury to the driver during a car collision.

[0062] The present invention also discloses a vehicle collision safety protection system, including a control device, which includes a memory and a processor, wherein a control program is stored in the memory, and when the control program is executed by the processor, it is used to implement the vehicle collision safety protection method described above.

[0063] The present invention also discloses a vehicle, which includes the vehicle collision safety protection system as described above.

[0064] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
