摘　　要：汽车电子稳定系统(electronic stability program,ESP)是汽车主动安全系统,能够很好的提高汽车的操纵稳定性和行驶安全性。该文针对ESP系统的特性,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,选取车辆横摆角速度作为控制变量,设计了模糊控制器,并对某款车型进行了仿真研究。结果表明横摆角速度模糊控制器能够对汽车进行很好的控制,提高了汽车的稳定性和安全性。The electronic stability program （ESP） was an active safety system which could improve the stability and safety of the vehicle. According to the electronic stability program characteristics, The Magic Formula tire model, seven DOF vehicle model and its reference model were built. The synthesized feedback control of vehicle yaw rate was designed based on fuzzy control principle. The results show that the designed controller can effectively enhance the stability and safety by controlling yaw rate
