摘　　要：该文基于多体动力学软件MSC.ADAMS/Car,建立了含有防抱死制动子系统的整车动力学模型,根据汽车稳定性控制的基本原理,运用模糊控制和比例积分微分控制理论设计了电子稳定性程序(ESP)控制系统。在MATLAB/Simulink环境下,建立了ESP控制系统和车辆动力学模型的联合仿真模型,并进行多种工况下的汽车操纵稳定性仿真试验。结果表明,所设计的ESP控制系统能有效地控制汽车的侧向加速度,且轨迹跟随性较好。Based on the multi-body dynamics software MSC.ADAMS/Car,a vehicle dynamic model with anti-locked braking system braking subsystem is established.According to the basic principles of the vehicle stability control,the control system of electromc stability program（ESP） is designed by fuzzy control theory and proportion integral derivative control theory.In the MATLAB/Simulink environment,the joint simulation model of the ESP control system and the dynamics model are established.Simulation of vehicle handling stability test in a variety of extreme working conditions is finished.The result shows the designed ESP can effectively control the vehicle lateral acceleration and improve the vehicle handling stability significantly.
