Patent ID: 6972537

Claim:
An electric power steering apparatus for applying a steering assisting force to a steering mechanism of a vehicle by driving a brushless motor in accordance with a steering torque applied to an operating unit for steering the vehicle, the electric power steering apparatus comprising: motor current detecting units provided at respective phases of the brushless motor, which detect values of motor currents flowing in the respective phases of the brushless motor and output detecting signals indicating the motor current values, respectively; a correction value calculating unit that calculates a correction value for correcting the motor current values provided based on the detecting signals by dividing a sum of the motor current values of all the phases of the brushless motor by a number of the phases of the brushless motor; a motor current value correcting unit that corrects the motor current values based on the correction value; and a motor driving unit that drives the brushless motor based on the motor current values corrected by the motor current value correcting unit.
