ABSTRACT:
In an electric power steering apparatus which assists a steering power by an electric motor, the difference between currents flowing into and flowing out from the electric motor is obtained, and an abnormality of the electric motor due to a ground fault is detected on the basis of this difference. When a state in which this difference is greater than a given value has continued for a predetermined period of time, the abnormality of the electric motor is detected. Upon the detection of the abnormality of the electric motor, a relay contact of a fail-safe relay circuit is made off so that the supply of electric power from a main power supply to the electric motor is cut off, thereby inhibiting the electric motor from assisting the steering power.
