A Simulation of Vehicle Lateral Stability Based on Fuzzy PID Control

摘要：

In order to improve the lateral stability of the vehicles at a high speed, a parameter self-tuning fuzzy PID control method to control the yaw moment couple with side slip angle of the front wheel is proposed, and a Fuzzy PID controller is designed. Based on Vehicle dynamic model analysis, and by using MATLAB/Simulink software, vehicles yaw rate and the side slip angle of the front at the step steering condition and the sine steering condition is simulated. The simulation results show that, compared to the vehicle only under ABS control, vehicle by fuzzy PID controller could reduce the yaw rate and the side slip angle of the front and back wheels effectively. Further more, the vehicles motion can be controlled in a stable region. Thus, the lateral stability of vehicles is improved.
