Abstract

An object of the present invention is to provide an electric power steering apparatus which can continue control even if some of current detectors that detect phase currents of a three-phase motor break down. Phase currents of the failure current detectors are calculated by using detected signals from the normal current detectors, and the electric power steering apparatus can be continued to be controlled by using the current values.
