This paper established an active suspension system for seven degrees of freedom model of a whole body. Two kinds of fuzzy control policy were designed. According to the whole vehicle system, one control policy was described in method one. And the vertical motion fuzzy logic controller, the pitch motion fuzzy logic controller, the roll motion fuzzy logic controller and the logic controller were established in method two. The simulation results indicate that the ride comfort and the control stability are ameliorated by the proposed controller.
