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。

Abstract

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.
