Abstract: To achieve an optimal control performance for the vehicles equipped with Active Stabilizer-bar and Active Front-wheel Steering, a coupling problem was researched with simulation. Firstly, a nonlinear vehicle dynamic model was established, and an active steering PID controller was designed. Then, based on the stabilizer-bar actuators, an active roll sliding mode controller and an anti-roll moment distribution fuzzy controller between front and rear axle were designed. Finally, the step steering and double-lane-change maneuver were simulated and analyzed. The simulation results show that the active steering can improve the roll performance, and the dynamic distribution and active steering can further improve the yaw stability, and guarantee the roll stability performance.
