摘　　要：为了提高开发效率,采用V型开发模式设计了汽车电子稳定程序的控制系统.在MATLAB/Simulink中建立了轮胎模型、车身模型和车辆参考模型,在AMESim中建立了四通道液压制动模型,并通过接口连接成汽车动力学联合仿真模型.以汽车横摆角速度为控制变量,采用模糊控制、PID控制等算法建立了控制系统.将硬件嵌入到整个仿真系统,进行硬件在环仿真试验.结果表明,实时仿真与离线仿真结果基本一致,ESP控制效果良好,提高了汽车的稳定性和安全性.In order to improve the efficiency, this paper has designed control system of vehicle Electronic Stability Program （ESP） with V-type development model. The tire model, body model and vehicle refer- ence model have been established in MATLAB/Simulink. The 4-channels hydraulic brake simulation has been established in AMESim. The vehicle dynamic model has been established through the interface of the two sets of software. The hierarchic structure controlling system of ESP is built on the basis of Fuzzy and PID control algorithm and yaw rate is ascertained as the control target. It chose the vehicle yaw rate as the control variables, and then the control system has been established by using fuzzy control and PID control algorithm. Then hardware is embedded in the whole simulation system, and the Hardware-In-the-Loop test is done. The results show that real-time simulation and off-line simulation results are basically the same, the control effect of ESP is good and ESP system can improve the stability and security of the vehicle.
