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.
