摘要
针对安全行驶问题,从纵向紧急制动与侧向转向换道两方面出发,对汽车主动避撞系统进行研究。首先,围绕车辆制动过程建立安全距离模型,设计了基于模糊控制的纵向紧急制动模型。其次,设计侧向换道的触发机制,并依据等速偏移轨迹和正弦函数叠加对侧向换道的路径进行规划。最后,通过对汽车避撞运行工况进行仿真,验证了模型的有效性。
In view of the safe driving problem,the active collision avoidance system of the vehicle is studied from the aspects of longitudinal emergency braking and lateral steering.Firstly,a safety distance model is established around the vehicle braking process,and a longitudinal emergency braking model based on fuzzy control is designed.Secondly,the trigger mechanism of the lateral lane change is designed,and the path of the lateral lane change is planned according to the constant velocity offset trajectory and the sinusoidal function superposition.Finally,the effectiveness of the model is verified by simulating the vehicle collision avoidance operation conditions.
