摘　　要：控制汽车的操纵稳定性是现代汽车提高安全性的重要途径之一。为了改善车辆在转向时或受侧向风作用时的操纵性和稳定性,对汽车电子稳定装置(Electronic stability program,ESP)的工作原理进行了研究,用二自由度整车模型进行了稳定性控制系统设计,并采用硬件在环仿真技术进行了快速控制原型的实时仿真。结果证明,控制器对汽车稳定性控制效果明显,实时仿真与离线仿真结果吻合。说明改进的方法可增加控制系统的稳定性和实时性。The control of vehicle stability is one of the important methods to improve the security of automotive. For improving the stability of automotive at turning or affected by side wind, the paper analyses the operating principle of the automobile electronic stability device ESP （ Electronic stability program）. A stability control system has been designed for a two degree - of - freedom vehicle model, and the hardware in the loop simulation method has been used to carry out the real - time simulation of the rapid control prototype. The result indicated that, the controller has obvious effect on automobile stability control, and the result of real - time simulation tallies with that of the off -line simulation basically.
