Abstract
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.
