Simulation and Study of Active Roll Control for SUV Based on Fuzzy PID

A virtual sport utility vehicle (SUV) model is built by using ADAMS/Car. The model is simplied with 95 DOFs equipped with active anti-roll bars in front and rear suspension. A fuzzy tunning PID controller using roll angle input source is applied in the active roll control. It is co-simulated under the Matlab/Simulink software environment and realizes the online coordination. The simulation results show that this controller has the ability of self-adjusting and decreases the body roll angle effectively. The vehicle riding comfort is ensured and the vehicle directional stability is improved.
