摘要
ESP系统是一种主动安全技术。文章通过MATLAB/Simulink建立汽车二自由度模型,将模糊PID以及PID和ESP结合起来,对得到的附加横摆力矩进行差动控制。通过CarSim和Simulink搭建联合仿真模型,分别以角阶跃信号以及正弦信号作为转向盘输入,通过观察汽车的横摆角速度来判断汽车的稳定性。对比发现,模糊PID在改善车辆稳定性方面优于PID,为ESP的研究给予一定的参考作用。
Electronic stability program(ESP) is a kind of safety technology. In this paper, a twodegree-of-freedom model of the vehicle was established by MATLAB/Simulink, and the differential control of the additional yaw moment was carried out by combining the fuzzy proportion integral differential(PID) and PID with ESP. The co-simulation model was built by CarSim and Simulink,and the angular step signal and sinusoidal signal were used as the steering wheel input respectively.The stability of the vehicle was judged by observing the yaw speed of the vehicle. It is found that fuzzy PID is better than PID in improving vehicle stability, which provides a certain reference for the research of ESP.
