A Driver Model for Dynamic Evaluation of the EPS Assistant Characteristics
Shen Huan, Tan Yunsheng and Mao Jianguo

Abstract:
Aim to evaluation the dynamic characteristics of Electric Power Steering system (EPS) at low cost design phase, a driver steering control model has been established in this study. The proposed driver model employs both the angle of upcoming road preview deviation and its derivative to calculate the desired yaw rate. Based on lateral dynamics model, the feed-forward control law has been designed, which product an expected steering wheel angle. To establish the dynamic relation between drivers and the steering system, the inertia of the human arm and the torque of the steering wheel are considered, and an interactive feedback controller is obtained. Serpentine line simulation shows that the established control system can effectively complete steering task and provide a closed-loop simulation approach for evaluation the assistant power characteristic of the EPS.
