摘　　要：在Matlab/Simulink中建立了魔术公式轮胎模型、七自由度车辆模型和车辆参考模型,以汽车横摆角速度为控制变量,采用模糊控制算法建立了控制系统,结合在AMESim中建立的四通道液压制动模型,通过接口连接建立汽车ESP联合仿真模型。在典型工况下对其控制效果进行仿真分析。结果表明,ESP可以对汽车进行较好的控制,提高汽车的稳定性和安全性。The Magic Formula tire model, seven DOF vehicle model and its reference model are es- tablished in Matlab/Simulink. The vehicle yaw rate is chosen as the control variables, and then the control system is established by using fuzzy control algorithm. By connecting the established 4-chan- nels hydraulic brake model in AMESim, the co-simulation model for ESP is established through the interface of the two software. The model is simulated to analyze its control effect in characteristic cy- cles. The results show that ESP can control the vehicle well and the stability and safety of the vehicle are enhanced .
