摘　　要：针对汽车底盘的两大重要组成—转向子系统和悬架子系统,建立起汽车侧向动力学模型、悬架动力学子模型以及考虑两者耦合效应的综合动力学模型;接着对四种不同控制策略的车辆系统进行了仿真对比,包括被动悬架兼前轮转向系统、主动抗侧倾杆控制系统、主动抗侧倾杆和四轮转向控制系统以及主动悬架与四轮转向的综合控制系统,得出:主动悬架和四轮转向综合控制系统能同时兼顾主动悬架和四轮转向的优点,使车辆的操稳性和平顺性大大提高。Depending on two important components of a vehicle chassis—a steering subsystem and a suspension subsystem, a lateral dynamic submodel, a suspension dynamic submodel and their integrated dynamic model with their interactions were built up. Then, the performances of the vehicle system with four different control strategies including a passive suspension and a front wheel steering system, an active anti-roll bar control system, an active anti-roll bar and a four-wheel steering control system as well as an active suspension and a four-wheel steering integrated control system, were investigated. It could be concluded that the integrated control system of an active suspension and a four-wheel steering could take the advantages of the active suspension and the four-wheel steering into account, it improved the vehicle’s handling and riding performance greatly.
