The fuzzy control is one of the promising control strategies in controlling the dampings of a semi-active automotive suspension. The focal point of the fuzzy damping control is how to consider the relative large degrees of freedom of the vehicle system under control and how to determine the control parameters of the fuzzy controller. In this paper, a seven degree of freedom vehicle ride model with semi-active suspension and damping fuzzy controller is proposed. For the parameter identification of the fuzzy controller, a new local improvement genetic algorithm is derived. Based on the proposed GA method and fuzzy control theory, the damping fuzzy control of the seven degree of freedom vehicle ride model is simulated and problems in the implementation are solved. An practical example is given.
