ABSTRACT:
An electric power steering apparatus that performs steering assist by transmitting a driving force produced by an electric motor to a steering mechanism. The electric power steering apparatus is provided with a driving target value setting section for setting a driving target value of the electric motor, a first factor setting section for setting a first factor on the basis of the driving target value, a temperature sensor for sensing the ambient temperature of the electric power steering apparatus, a second factor setting section for setting a second factor on the basis of an output of the temperature sensing section, a driving target value correction section for correcting a driving target value on the basis of the first and second factors, and a motor driver for driving the electric motor on the basis of the driving target value thus corrected.
