Abstract:
The electric power steering apparatus has a plurality of power systems each including an inverter apparatus provided corresponding to a plurality of wiring sets of a motor thereof. The control section calculates the assist current to be supplied to the motor using a one power system failure-state map when the inverter apparatus or its corresponding wiring set of one of the power systems fails, or using a vehicle speed detection failure-state map when there is a failure in detecting the vehicle speed. The assist current limit value in the one power system failure-state map and the assist current limit value in the vehicle speed detection failure-state map are set to the same value.
