| 发明名称 | Apparatus and method for removing hysteresis of motor driven power steering | ||
| 摘要 | An apparatus for removing hysteresis of motor driven power steering (MDPS) may include: a motor driving unit for rotating a motor; a key on/off sensing unit for sensing a key on/off of a vehicle; and an electronic control unit (ECU) for receiving a key off state of the vehicle from the key on/off sensing unit and repeating a sweep function a preset number of times. The sweep function may include applying a current having an asynchronous frequency, which does not coincide with a synchronous frequency of the motor, to the motor through the motor driving unit. | ||

| 主权项 | 1. An apparatus for removing hysteresis of motor driven power steering (MDPS), comprising: a motor; a key on/off sensor configured for sensing a key on state or a key off state of a vehicle; and an electronic control unit (ECU) configured for receiving the key off state of the vehicle from the key on/off sensor and for repeating a sweep function a preset number of times, wherein the sweep function comprises applying a current having an asynchronous frequency, which does not coincide with a synchronous frequency of the motor, to the motor while alternating direction of the current one or more times. | ||
