DEVICE AND METHOD FOR CORRECTING THE UNBALANCE OF VOLTAGE REDUCTION, AN ELECTRIC POWER STEERING SYSTEM CAPABLE OF CORRECTING THE UNBALANCE OF VOLTAGE REDUCTION GENERATED IN AN ELECTRIC CONTROL UNIT

摘要

PURPOSE: Device and method for correcting the unbalance of voltage reduction, an electric power steering system are provided to correct the unbalance of voltage reduction generated in an electric control unit by correcting the applied voltage for applying to a motor in consideration of voltage reduction.;CONSTITUTION: A device for correcting the unbalance of voltage reduction comprises an applied voltage calculating unit(110) and an applied voltage correcting unit(120). The applied voltage calculation unit calculates the applied voltage for applying to a motor(10) in a first voltage applying timing. The applied voltage correcting unit measures the real applied voltage applied to the motor in the first voltage applying timing. The applied voltage correcting unit corrects the next applied voltage for applying to a motor in a second voltage applying timing after a first voltage applying timing based on the difference between the calculated applied voltage and the measured applied voltage.;COPYRIGHT KIPO 2012
