摘　　要：车辆的稳定性和安全性是人们衡量一辆汽车性能最基本的指标,通过在matlab/simulink中建立汽车动力性模型,对汽车的操纵稳定性进行仿真,对比前轮转向和四轮转向系统,四轮转向系统对于提升汽车的操纵稳定性,具有十分显著的作用。低速时转向半径较小,转向更加灵活;高速时,能够很快的根据情况改变车道,确保侧偏角始终接近于零,提高循迹跟踪能力,减少侧滑和甩尾现象的出现。With the development of vehicle technology and the remarkable improvement of People＇s living standard, People＇s requirements of vehicle stability are also increasing, and making the vehicle hand ling and stability as an important direction of the car. Compared with the Front-Wheel Steering system, Four Wheel Steering system has the following advantages：.At the low speed, the 4WS can reduce the turning radius, improve the mobility, and make it easier to access to parking lots or maneuver in narrow. At the high speed, the 4WS can change lanes quickly, ensure that the sideslip angle is busily zero, improve the tracking capacity and reduce the skid and drift Phenomena, so as to improve vehicle handling and stability and enhance security.
