电动助力转向（EPS）系统是在机械转向系统的基础上，加入电动机作为执行机构，使得转向轻便。由于电机转子、减速机构的摩擦阻尼，致使转向系统的回正性能变差。针对系统回正不足，设计了基于方向盘角度信息查表的主动回正控制算法，进行了电控单元（ECU）软、硬件设计。结果表明，该控制策略可使方向盘顺利回到接近中点位置，不过度。

Electric Power Steering System is development from the simple Mechanical Steering System,uses electric motor to assist power for reduction in steering torque. Friction of Motor rotor and worm gear destroys the performance of return-to-center. In order to improve the performance of return-to-center,the control strategy by searching table for steering wheel aligning based on angle of steering wheel is proposed and the system’s hardware and software are designed. The experiment results show that the control strategy can make the steering wheel return to the center smoothly and mitigate the aligning overshoot.
