Description

Vehicle seat control method, system, equipment and medium Technical Field The present invention relates to the field of vehicle control technologies, and in particular, to a vehicle seat control method, system, device, and medium. Background Along with the improvement of intelligent and comfort demands of automobiles, the adjusting function of the automobile seat is gradually updated from basic position adjustment to personalized comfort adjustment. In the prior art, a pneumatic adjusting system of an automobile seat mainly focuses on static or semi-static comfort adjustment, and the key logic of the pneumatic adjusting system is that pressure values of passengers are collected through sensors arranged at the waist, the side wings, the legs and the like, and comfort state values of the passengers are calculated based on the pressure values, so that supporting positions and forces of waist supports and the side wings are correspondingly adjusted. However, the prior art has the obvious technical defect that the seat adjusting system can only respond to the pressure distribution change of the passengers, and completely neglects the influence of the dynamic running state of the vehicle on the sitting posture and the support requirement of the passengers. In the actual running process of the vehicle, when dynamic working conditions such as emergency braking, rapid steering and the like are carried out, the passenger can greatly tilt forward due to inertia, at the moment, the traditional comfort adjusting system cannot make any effective response, and the body of the passenger is easy to slide and unstable in posture. The defect not only can reduce driving comfort, but also can influence the control stability of a driver due to shaking of the gesture of the passenger, increases potential safety risks, and can not meet the accurate requirement of a user on seat support in a severe driving scene.
