摘要： An electric power steering device which, when an abnormality occurs in one phase of a three-phase brushless motor, permits continuous driving of the motor using the remaining two phases without deteriorating the steering feeling. When a power distribution abnormality of a drive system of one phase of respective phase coils has been detected by an abnormality detection section, an abnormal-time phase current instruction value for using the remaining two phase coils is calculated based on a steering assist electric current instruction value, and an electric motor is driven based on that abnormal-time phase current instruction value. At that time, when an electrical angle falls within an acceleration region, the abnormal-time phase current instruction value is increased or decreased for correction in order to accelerate rotation of the three-phase brushless motor in a steering direction.
