The invention belongs to the technical field of vehicle collision control, and particularly relates to a control system and method for preventing secondary collision after vehicle collision. According to a vehicle collision signal monitored by a vehicle collision unit, whether a driver operates the vehicle or not is judged through a driver monitoring system, a driving control system, a steering control system and a braking system of the vehicle, and meanwhile the intention of the driver and the vehicle state are judged according to the current vehicle speed and the current wheel speed of the vehicle; then, a braking system and a steering system of the vehicle are actively controlled, it is guaranteed that the vehicle does not move and steer unexpectedly, and damage caused by secondary collision of the vehicle is reduced as much as possible through existing technical equipment of the vehicle; and the safety of the vehicle is improved while the cost is not increased.
本发明属于车辆碰撞控制技术领域,具体涉及一种防止车辆发生碰撞后出现二次碰撞的控制系统及方法;根据车辆碰撞单元监测到的车辆碰撞信号,通过车辆的驾驶员监测系统、驱动操纵系统、转向操纵系统及制动系统判断驾驶员是否操作车辆,同时根据车辆当前的车速和轮速判断出驾驶员的意图及车辆状态,然后对车辆的制动系统和转向系统进行主动控制,保证车辆不出现非预期的移动和转向,利用车辆现有的技术装备,尽可能减轻车辆二次碰撞带来的伤害;在无成本增加的同时提升车辆的安全性。
