摘要

Vehicle running at high speed if affected by crosswind or steering handling may spin or drift out since the yaw moment produced is not big enough to stabilize it. In order to prevent these dangerous situations, a fuzzy direct yaw moment controller is designed in this paper, since it is simple and suitable for nonlinear system. This vehicle stability control system is based on model following control method. The side slip angle and yaw rate which indicate the vehicle's stability and handling performance are chosen as the control variables. The response of the bicycle model is selected as the reference value. In order to evaluate the performance of the controller, simulations of lane change and J-turn maneuver are carried out. The results show that the stability and handling performance of the vehicle are improved.
