Depending on the two important components of vehicle chassis—steering subsystem and suspension subsystem, lateral dynamics submodel, suspension dynamics submodel and the integrated dynamics model with their interactions were built up. Then the performances of the vehicle system with four different control strategies were investigated, including the passive suspension and front wheel steering system, the active anti-roll bar control system, the active anti-roll bar and four wheel steering control system and the active suspension and four wheel steering integrated control system. It can be concluded that the integrated control system of active suspension and four wheel steering can take the advantages of active suspension and four wheel steering into account, while improving the vehicle’s handling and riding performance greatly.
