A Driver Model for Dynamic Evaluation of the EPS Assistant Characteristics
The Electric Power Steering system (EPS),as a new power steering technology,has advantages of steering agility and road feeling clearly.However,there is no effective driver model which can be used to evaluating EPS under low cost designed phase.The interaction between driver and the steering system has been studied in this paper,and a new driver steering control model has been established.The proposed driver model employs both the angle of upcoming road preview deviation and its derivative to calculate the desired yaw rate.The feedforward correction control law has been designed based on lateral dynamics model,which product an expected steering angle.Aim to establish dynamic relation,arm inertia and steering wheel torque are considered and an interactive feedback controller of arm and steering wheel is designed.Serpentine line simulation shows that the established control system can effectively complete steering task,and provide a closed-loop simulation approach for the EPS assistant power characteristic evaluation.
