In order to solve the control problem of active suspension, improve the ride comfort, three degree freedom of 1/4 vehicle active suspension system dynamics model with the driver’s model was established, and the variable universe adaptive fuzzy controller based on fuzzy inference applied to the active suspension system was designed. The universe size of the system fuzzy controller can be adjusted automatically according to system deviation, the fuzzy control accuracy can be improved effectively. Through the comparison of passive suspension, the active suspension applied variable universe adaptive fuzzy controller, the acceleration of body and seat can be reduced substantially, and the riding comfort and the running smoothness can be improved effectively.
