Simulation on Handling Stability Performance of 4WS Vehicle

The handling and stability performance of the four-wheel steering vehicle with near slip angle minimization is studied.Based on an established dynamic model of the four-wheel steering vehicle,the state equation of system and the transfer function about yaw velocity and lateral acceleration to the front wheel steering angle are obtained.Simulation on the time domain and frequency domain of the four-wheel steering vehicle in Matlab/Simulink software environment is described.The advantage of the four-wheel steering vehicle compared with the front wheel steering vehicle is showed.The handling and stability performance of the four-wheel steering vehicle is better than that of the front wheel steering vehicle.
