| 摘 要： | 为了改善装有电子助力转向系统（EPS）的车辆操纵稳定性，分析研究了EPS中引入横摆角速度负反馈对车辆操纵稳定性的影响，建立了包含EPS的人-车系统数学模型，并利用SIMU—LINK工具箱进行了仿真分析。结果表明：该模型在EPS中引入横摆角速度负反馈，可以显著改善前轮角阶跃输入下车辆的横摆角速度的瞬态响应；EPS助力矩响应曲线上升平稳缓慢，有利于汽车在低附着系数路面高速转向行驶的操纵，从而提高了汽车的行驶安全性。

| Abstract: | In order to improve the vehicle manipulating stability with electric power steering system(EPS),the effect of introducing yaw angle rate negative response into EPS is analysed,a man-vehicle mathematic model including EPS is built.The software toolbox of SIMULINK is used to simulation the model.It is shown that vehicle's yaw angle rate response is improved by introducing yaw angle rate negative feed into the model with front wheel's angle step input,the EPS powered torque response curve arises evenly and slowly,this is useful to vehicle's driving at high speed on low friction coefficient road,so the vehicle's driving safety can be improved.1 tab,4 figs,8 refs. |
