A seven-degree of freedom whole body model with an active suspension system is described in the paper. First, construction of fuzzy control system is obtained. One fuzzy control discipline is designed. The fuzzy controller for vertical motion, fuzzy controller for pitch motion and roll motion is established. Second, controller for logical operation is designed, and the sketch of the composed fuzzy control system is presented. In addition, simulation analysis is obtained. The simulation results indicate that the ride comfort and the control stability is ameliorated by the proposed controller. Finally, simulation analogue of experiment is gained and the simulation environment of electronically controlled air suspension is constructed.
