摘　　要：阐述了四轮转向车辆的特点,基于Matlab/Simulink研究了横摆率跟踪的四轮转向车辆的操纵稳定性。并给出了仿真实例和结果,表明4WS车辆在高速范围内保持对操纵反应的灵敏、一致又不过度,在降低驾驶员操纵难度的情况下,较大地改善了车辆在高速时的瞬态操纵稳定性。In this paper, the dynamic characteristics of four-wheel steering (4WS) vehicle are illustrated. With the software of Matlab/Simulink, the handling stability of 4WS vehicle based on yaw-rate tracking control is studied, and the simulation example and result are given also. Simulation shows that the 4WS vehicle is agility to and consistent with steering input and the transient handling stability is improved distinctively without increasing drivers handling difficulty.
