摘　　要：为有效解决现有主动避撞系统采用单一制动避撞控制策略难以适应不同紧急工况下的避撞需求,提高智能汽车的主动安全性,本文提出了一种集合制动与转向避撞模式的主动避撞策略。首先通过运动学建立紧急制动安全距离模型和紧急转向安全距离模型,接着根据路面附着系数和相对车速区分不同避撞模式的安全收益范围,最后确定主动避撞策略的介入模式。In order to effectively solve the problem of using a single braking collision avoidance control strategy to adapt to the collision avoidance needs of different emergency conditions in existing active collision avoidance systems,and improve the active safety of intelligent vehicles,this paper proposes an active collision avoidance strategy that combines braking and steering collision avoidance modes.Firstly,an emergency braking safety distance model and an emergency turning safety distance model are established through kinematics.Then,the safety benefit range of different collision avoidance modes is distinguished based on road adhesion coefficient and relative speed.Finally,the intervention mode of the active collision avoidance strategy is determined.
