Yaw Moment Control for Motor Electric Vehicle with Four-Wheel Hub Based on Parameter Self-Regulation Fuzzy Control

For the yaw moment control of motor electric vehicle with four-wheel motor, the parameter self-regulation fuzzy control theory is studied in this paper. And the yaw moment hierarchical control structure of the vehicle is determined. The additional yaw moment decision-making controller is designed based on parameter self-regulation adaptive fuzzy control theory. Taking advantage of the independent control of the four-wheel driving torqu, rule allocation method is used for four-wheel driving forces distribution. Using CarSim and Matlab/Simulink co-simulation test, the control method is verified by selecting the input mode of the continuous sine steering wheel angle. The results show that the yaw moment based on parameter self-regulation fuzzy control method can improve vehicle driving stability effectively.
