Abstract

In order to improve the lateral stability of the vehicles at a high speed, a DYC control method is applied to four-wheel steering vehicle control. Through model tracking method, a feedback controller which used direct yaw moment as the controlled output based on fuzzy control theory is designed, meanwhile, classic 4WS control as a feed forward is used to improve the system dynamic response. Several simulations were conducted at different vehicles speed. The results proved that by DYC control and used fuzzy control, the four-wheel steering vehicle stability could be improved.
