摘  要:
在电动助力转向系统中引入横摆角速度反馈传感器,建立了包含电动助力转向系统的人-车系统数学模型;经模拟仿真分析,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;并且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时的操纵,从而提高汽车的行驶安全性。

摘  要:
Using a yaw angle rate sensor into EPS(electric power steering system),a man-vehicle system model is built up in the paper.By simulating and analyzing,it is shown that vehicle's yaw angle rate response is improved remarkably 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 high speed at low friction coefficient road then improve vehicle's driving safety.
