Provided are: an electric motor that applies steering assist force to a steering wheel; a target current determination unit 25 that calculates a target current to be supplied to the electric motor on the basis of steering torque of the steering wheel; and a correction unit 27 that, when a rotation speed of the electric motor is less than a predetermined rotation speed, corrects the target current calculated by the target current determination unit 25 to be reduced on the basis of an actual current supplied to the electric motor and a time during which the actual current is supplied. Thereby a technique is provided to suppress a failure of the electric motor due to an excessive current flowing through the electric motor with higher accuracy.
