Active return-to-center control of an electric powered steering system
Jing Liqun Ji Xuewu
(State key laboratory of safety and energy, Tsinghua University)
【Abstract】In the development process of EPS system, it was found that the vehicle installing an electric powered steering system (EPS) without return-to-center control will not approach to neutral position automatically after steered when the car rides at low speeds. The reason for the steering wheel not returning to center was discussed based on the analysis for returning moments. Then the power and torque signal change pattern during returning travel was studied. An active returning method was proposed in this paper, in which the holding torque before returning was used as the returning characteristic parameter to determine the motor current and its duration time, and the change of torque signal from nonzero to zero was used as criteria to determine the returning state. Finally, the proposed active returning method was verified on the vehicle and it was found that the method improved EPS return ability obviously.
