Zero-gravity seat belt control method and system and vehicle
The invention provides a zero-gravity seat belt control method and system and a vehicle, and relates to the technical field of vehicles. The zero-gravity seat safety belt control method comprises the following steps: acquiring a seat angle; determining delay time according to the seat angle; and when the frontal collision occurs, controlling the safety belt according to the delay time. The delay time of safety belt control is determined according to the angle of the seat, when a frontal collision occurs, a passenger moves forwards due to inertia, the forward moving speed of the lower limbs is slower than that of an upper trunk due to the fact that the lower limbs are tightly attached to the seat and friction force, and the upper trunk rotates forwards due to inertia; after the body of the passenger becomes straight, the waist of the passenger is restrained through the safety belt, namely, the function strategy of the safety belt can be adjusted in a targeted mode according to different sitting posture angles, and therefore the passenger in the zero-gravity sitting posture is protected.
本发明提供了一种零重力座椅安全带控制方法、系统及车辆，涉及车辆技术领域。本发明所述的零重力座椅安全带控制方法，包括：获取座椅角度；根据所述座椅角度确定延迟时间；当正面碰撞发生时，根据所述延迟时间控制安全带。本发明根据座椅角度确定安全带控制的延迟时间，当正面碰撞发生时，乘员会由于惯性朝向前方移动，由于下肢与座椅紧贴，摩擦力导致下肢向前移动的速度相比上躯干会更慢，而上躯干会由于惯性向前旋转，通过延迟控制安全带，可以使得乘员的身体变得更“直”后再通过安全带约束乘员腰部，即可以根据坐姿角度的不同针对性地调整安全带功能策略，从而对零重力坐姿下的乘员进行保护。
