Abstract

The influence of the nonlinear tires to the vehicle yaw stability was researched. And the dynamics model of a full vehicle which equipped the active roll stabilizer and active front steering system were set up based on vehicle dynamics theory. Also an active roll stabilizer and active front steering system controller were designed based on the motion coupling relationships between active roll stabilizer and active front steering system. The active anti-roll moment distribution Fuzzy PID controller was designed to coordinate the two systems and enhance the vehicle roll and yaw stability during steering. The vehicle in the steering working situation is simulated with MATLAB/Simulink, and the simulation results were verified in Carsim. The results show the effectiveness of proposed coordinated control strategy.

Key words
