The invention discloses an automobile mechanical impact buffering system and a control method in the technical field of vehicle safety, in order to reduce maintenance cost generated during vehicle collision, according to the technical scheme, the automobile mechanical impact buffering system comprises a first-stage damping system, a second-stage damping system and a third-stage damping system which are sequentially arranged from an automobile head bumper to a trunk, the joint of the first-stage damping system and the vehicle head bumper is provided with a sensing device for collecting collision information of a vehicle in front of the vehicle, and the second-stage damping system is a control system used for judging whether the safety air bag is unfolded or not according to the information transmitted by the first-stage damping system. Compared with the prior art adopting a mechanical filter, in the technical scheme, the second-stage damping system is used for collecting the torque transmitted by the first-stage damping system and judging whether the safety air bag is unfolded or not, unfolding of the safety air bag during a slight car accident is avoided, the number of accessories needing to be replaced after the car accident is reduced, and cost is saved; meanwhile, the influence on the sight of a driver when the airbag is unfolded is avoided.
本发明公开了车辆安全技术领域的一种汽车机械撞击缓冲系统及控制方法,以降低车辆碰撞时产生的维修费用,这种技术方案包括沿车头保险杠至后备箱内依次设置的第一级阻尼系统、第二级阻尼系统和第三级阻尼系统,第一级阻尼系统与车头保险杠的连接处带有收集汽车前车碰撞信息的感应装置,第二级阻尼系统用于根据第一级阻尼系统传递的信息对安全气囊是否展开做出判断的控制系统。相对于采用机械滤波器的现有技术,本技术方案中使用第二级阻尼系统收集第一级阻尼系统传递的力矩,判断是否展开安全气囊,避免了轻微车祸时安全气囊的展开,降低了车祸后需要更换配件,节省了成本,同时避免了气囊展开时对驾驶员视线的影响。
