ABSTRACT:
The invention provides an electric power steering apparatus in which a duty ratio upper limit value is obtained on the basis of a vehicle speed of a vehicle and a supply voltage for a motor and a target duty ratio is determined as a value not exceeding the duty ratio upper limit value, so as to prevent an excessive steering assisting force from being caused by the malfunction of a driving current detecting circuit for the motor.
