摘　　要：在汽车线性二自由度模型的基础上建立了四轮独立转向(4WIS)车辆的动力学模型,对其在前轮角阶跃输入下的稳态响应进行了具体的分析。求出了其横摆角速度增益,分析了稳定性因数对其稳态响应的影响。同时借助Matlab将其与前轮转向(FWS)车辆对比,具体地指出了二者的差异。Establish the dynamic model of a four wheel independent steering（4WIS）vehicle based on a 2 degrees of freedom linear model of the car.Its steady-state response under the step input of the front wheel corner was analysised specifically and the yaw rate and the affect of the understeer parameter were found.Meanwhile,with the help of Matlab,the four wheel independent steering vehicle and the conventional front-wheel steering（FWS） vehicle were compared.The result shows the difference between the 4WIS and the FWS.
