The invention belongs to the technical field of automobile anti-collision control, and particularly relates to a vehicle emergency collision avoidance decision-making planning method suitable for various dangerous working conditions, which is provided with an emergency active collision avoidance decision-making method, analyzes and calculates the current collision risk of a vehicle according to different dangerous traffic scenes and the state of the vehicle, and provides an emergency active collision avoidance decision-making method. And the vehicle executes four collision avoidance operations of collision early warning, braking collision avoidance, steering collision avoidance or braking pre-collision according to the decision logic, so that the safety of the vehicle is ensured. The collision risk is calculated through a collision avoidance safety distance model, and according to the magnitude of the collision risk, vehicle collision early warning, braking collision avoidance or steering collision avoidance are achieved; and when the vehicle on the side opposite lane crosses the line and runs, the collision risk is calculated according to the collision time, and collision avoidance operations of collision early warning and steering collision avoidance are adopted. When the collision avoidance operation cannot avoid the collision, the vehicle adopts the braking pre-collision operation, so that the collision harm is reduced.

    本发明属于汽车防碰撞控制技术领域,具体涉及一种适应多种危险工况的车辆紧急避撞决策规划方法,其设置了紧急主动避撞决策方法,根据不同的危险交通场景以及自车所处的状态,分析、计算车辆当前的碰撞风险,使车辆按照决策逻辑执行碰撞预警、制动避撞、转向避撞或制动预碰撞四类避撞操作,保证车辆安全性。通过避撞安全距离模型计算碰撞风险,按照碰撞风险大小,使车辆碰撞预警、制动避撞或转向避撞;当旁侧对向车道车辆越线驶来时通过碰撞时间计算碰撞风险,采用碰撞预警、转向避撞的避撞操作。当以上避撞操作均无法避免碰撞时,车辆采用制动预碰撞操作,降低碰撞危害。
