In the automobile driving process, the collision judgment result of the automobile is obtained, and then the current riding condition of the automobile and the current inclination angle of the automobile seat backrest are combined, so that whether the inclination angle of the automobile seat backrest needs to be regulated or not can be automatically and accurately judged by utilizing the three information, and therefore the inclination angle of the automobile seat backrest can be timely regulated when the automobile is about to collide, personal safety of passengers is ensured as much as possible, and safety risks of the automobile passengers in the collision process are reduced.
In some embodiments, the determining, by the ADAS system of the automobile, whether the automobile collides, to obtain a collision determination result, includes:
judging the relative distance and the relative speed between the automobile and the front automobile through an ADAS system of the automobile; the front vehicle may be a vehicle directly in front of or in front of and at a distance from the host vehicle in the horizontal direction.
Obtaining the collision judgment result according to the relative distance and the relative speed;
the collision judgment result comprises at least one of the following:
whether the automobile collides, the time of the collision of the automobile, the collision mode of the automobile and the intensity of the collision of the automobile. For example: if the speed of the automobile is greater than that of the front automobile and the relative speed of the automobile and the front automobile reaches 30 km/h, the intensity is confirmed to be high, and the backrest angle of the automobile needs to be adjusted.
The relative distance and the relative speed between two vehicles are judged through the ADAS system, and a collision judgment result can be automatically obtained, so that the angle of the automobile backrest can be timely adjusted when the automobile backrest is required to be adjusted.
In some embodiments, the obtaining the current ride of the car comprises:
judging the current riding condition of the automobile through the seat gravity sensor of the automobile and/or the safety belt locking condition of the automobile; the belt buckle condition is whether the belt is fastened/buckled.

The second optimal tilt angle may be the same as or different from the first optimal tilt angle.
If the collision judgment result shows that the automobile is crashed within the preset time, the passenger is not on the passenger seat of the automobile in the current riding condition, but the passenger is on the rear of the passenger seat, and the current inclination angle of the passenger seat backrest is larger than the preset inclination angle, the passenger seat backrest is in a lying or large-angle position, and the passenger seat backrest angle is too large and reduces the living space of rear passengers when the automobile collides, so that an air bag controller of the automobile can send out an ignition signal to enable an air generator of the automobile to generate air, and the passenger seat backrest is pushed forwards to a second optimal inclination angle, so that the living space of the passenger behind the passenger is increased, the safety of the rear passengers is protected, and the problem that the living space of the front passenger seat backrest is large in the collision process or the rear passengers is insufficient in the lying state is solved.
In some embodiments, the determining whether to adjust the reclining angle of the vehicle seat back according to the collision determination result, the current seating condition, and the current reclining angle includes:
if the collision judgment result indicates that the automobile is in a rear-end collision within a preset time period, the current riding condition is that the front passenger and the rear passenger of the automobile are arranged, the current inclination angle of the seat back of the front passenger is not larger than the preset inclination angle, an ignition signal is sent out by the air bag controller of the automobile, and the gas generator of the automobile generates gas to push the seat back of the front passenger to a third optimal inclination angle.
If the collision judgment result shows that the automobile is in rear-end collision within the preset time, the current riding condition is that the front passenger is arranged on the front of the automobile, the rear passenger is not arranged on the rear passenger, and the current inclination angle of the seat backrest with the front passenger is not larger than the preset inclination angle, the inclination angle of the front seat is in a normal range under normal conditions, but the automobile is about to be in rear-end collision, if serious truck-entering accidents are about to happen, the front passenger possibly gets stuck by the front automobile at the head part and the like because the living space is too small, therefore, the air bag controller of the automobile can send out an ignition signal to enable the gas generator of the automobile to generate gas, thereby pushing the front passenger backrest backwards to a third optimal inclination angle, increasing the living space of the front passenger during rear-end collision, protecting the safety of the front passenger, and solving the problem of insufficient living space of the front driver and the passengers under the rear-end collision condition.
In some embodiments, the method further comprises:
and determining a first optimal inclination angle, a second optimal inclination angle and a third optimal inclination angle of the backrest of the automobile seat according to the load of the automobile seat and the collision judging result.
According to the load and the collision judgment result of the automobile seat, the first optimal inclination angle, the second optimal inclination angle and the third optimal inclination angle of the front-back inclination of the automobile seat backrest can be automatically determined, so that the optimal inclination angles can be determined in a targeted and intelligent manner according to the actual load and the collision judgment result of the seat, the seat backrest can be at an optimal position when the automobile collides, enough living space is provided for passengers, and the safety of the passengers is ensured as much as possible.
Of course, in order to improve the accuracy of the determination result of the optimal reclining angle, it is necessary to preset the correspondence relationship between the load of the seat, the collision determination result, and the optimal reclining angle in advance.
For example: if the collision determination result is that a frontal collision is imminent, the higher the load of the passenger seat, the more the passenger in the passenger seat is, and therefore, the greater the third optimal reclining angle should be in order to reserve a sufficient living space for the passenger in the passenger seat.
In addition, for convenience, the first, second, and third optimal inclination angles may also be preset inclination angles, for example: the first and second optimal tilt angles may be angles greater than 90 degrees, such as 95 degrees or 100 degrees, and the third optimal tilt angle may be a large angle of 170 degrees, 160 degrees, etc.
The technical scheme of the present disclosure will be further described with reference to fig. 2, and the present disclosure is mainly implemented by linkage ADAS (Advanced Driving Assistance System ), an air bag controller, and a seat system, in which a seat back can be driven by a gas generator to implement rapid forward and backward movement. The ADAS is used for predicting whether collision is about to happen, the intensity of collision and the specific collision form such as a drilling truck, the air bag controller receives the prediction information of the ADAS, judges the riding condition of passengers at all positions of the seat according to the seat gravity sensor and the safety belt locking signal, and judges the backrest position through the backrest position sensor. And the air bag controller judges whether to ignite a generator positioned in the seat back according to the input information, and pushes the seat back to adjust to the optimal protection position.
