Abstract: In order to solve the problem that active 4-wheel steering(4WS) vehicle might lose its handling stability when it suffers lateral interference or changes its driving route, a 4WS vehicle driven system was built based on the single-point preview driver modeland a dynamic vehicle model with 3 degree of freedom & an improved sliding model controller on 4WS. A double lane driving path model was designed to test the new system. Meanwhile, a simulation model of this vehicle driven system was built and simulated with Matlab/Simulink software. The simulation results were compared with those of 4WS with classical type sliding model control and the uncontrol front wheel steering (FWS) under similar parameter condition. The simulation results indicate that the model can more effectively track the given double lane driving path, realize the expected yaw rate and ensure side-slip angle, keep the body roll angle and roll angular speed in a small size. And it behaves favorable performs in robustness under lateral interference.
