摘　　要：利用ADAMS软件建立了具有四轮独立制动的整车多体动力学模型,在Matlab环境中设计了PI控制的车辆稳定性控制(VSC)系统,通过定义ADAMS与Matlab两种软件间的数据交换接口将设计的控制系统模型与整车模型相结合,对带有VSC系统的汽车进行了典型行驶工况下的仿真试验。研究结果为设计车辆动力学稳定性控制系统提供了一种有效的验证方法,弥补了现实物理试验条件的缺乏;并为VSC系统在车辆工程中的实际应用提供了一定参考。A multi-body dynamic model of the full vehicle was established by using automatic dynamic analysis of mechanical systems （ADAMS） software. A PI controller has been designed for the vehicle stability control （VSC） system under Matlab environment. By way of defining some data exchange interfaces between two kinds of software, the control system has been combined with the full vehicle model and thus, the whole electricity and machine system close-loop simulation model was constructed. The dynamic response of vehicle with VSC system under various operating condition was simulated. The simulation tests indicated that the VSC system could obviously improve vehicle stability and route follow capability. The result of study provided one effective verification method for the performance of VSC system.
