The invention discloses a one-key aligning system and method for an automobile steering wheel, and the system comprises a steering sensing device, a power-assisted steering motor, a motor controller,an electric control unit, and a steering wheel aligning key. When the electric control unit receives a steering wheel aligning instruction input by the steering wheel aligning key, a deviation rectifying steering control instruction is sent to the motor controller according to the current deflection direction, sensed by the steering sensing device, of the steering wheel. And the motor controller controls the power-assisted steering motor to drive the steering wheel to return according to the deviation-rectifying steering control instruction. According to the steering wheel aligning device, theindependent key, namely the steering wheel aligning key, is arranged to input the steering wheel aligning instruction to the electric control unit, and the electric control unit controls the motor controller based on the steering wheel aligning instruction after the current deflection direction of the steering wheel is determined, so that the power-assisted steering motor drives the steering wheel to be aligned; therefore, the trouble of a driver is reduced.

    本发明公开了一种汽车方向盘一键回正系统及方法,所述系统包括转向传感装置、转向助力电机、电机控制器、和电控单元,还包括方向盘回正按键;当所述电控单元接收到所述方向盘回正按键输入的方向盘回正指令时,根据所述转向传感装置感测到的方向盘的当前偏转方向向所述电机控制器发出纠偏转向控制指令,所述电机控制器根据所述纠偏转向控制指令控制所述转向助力电机驱动方向盘回正。本发明中通过设置一个单独的按键——方向盘回正按键,以向电控单元输入方向盘回正指令,电控单元则基于此方向盘回正指令、在确定了方向盘的当前偏转方向后、对电机控制器进行控制,以令转向助力电机驱动方向盘回正,从而减少驾驶员的困扰。
