Abstract
The paper studied the optimal control laws of 4WS during single lane changes using a driver model of preview follower method based on the certain vehicle model. The actual vehicle models are considered as uncertain systems. The front and rear wheels cornering stiffness and outer disturbance vary over a limited range. The adaptive model - following a variable structure control method is used for controlling front and rear wheels steering of the actual vehicle, so that the steering characteristics of uncertain vehicle models can follow the characteristics of reference model. Simulation results have demonstrated that the control system can overcome the effects of parameter perturbations and outer disturbances on system stability.
