Based on the models of unlinear tyre and full vehicle dynamics, the characteristics of the control methods of yaw moment and front wheel active steering under the conditions of excessive vehicle and less steering are analyzed. The technology of unlinear Fuzzy-PID with robustness for vehicle stability control is selected. The Fuzzy-PID controllers are designed whose tracking objects are ideal yaw rate and side slip angle and the outputs are wheel braking force and front wheel steering angle. The simulation experiments by two methods, yaw moment stability control which is based on the optimum slip rate of tyre and active steering control that is based on front wheel nestification, are carried out. The results prove that the vehicles applied Fuzzy-PID control have good performance stability.
