基于横摆角速度的汽车ESP系统的仿真研究

Simulation of Vehicle Electronic Stability Program Based on the Yaw Rate

横摆角速度是控制汽车横向稳定性的主要控制变量。基于横摆角速度对汽车ESP系统进行仿真研究,首先在建立ADAMS/CAR中建立汽车整车模型,然后建立汽车理想二自由度参考模型,设计横摆角速度反馈控制PID控制器。仿真结果表明,基于横摆角速度控制的ESP系统控制的汽车明显改善汽车横向稳定性,提高了汽车行驶安全性能。

The main control variables which control lateral stability of vehicle is the yaw rate, In this thesis, the simulation of ESP is based on the yaw rate. First, the software ADAMS/CAR is applied to create the model of whole vehicle, and then 2D freedom ideal vehicle model is created, to design PID controller. The result, of simulation shows that the vehicle with ESP based on the yaw rate feedback control could improve the lateral stability and the driving safety.
