Abstract:
1. An electric power steering apparatus that performs steering assist by transmitting a driving force produced by an electric motor to a steering mechanism, comprising: 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 set by the driving target value setting section; a temperature sensor for sensing an ambient temperature of the electric power steering apparatus including the steering mechanism; a second factor setting section for setting a second factor on the basis of an output of the temperature sensor; a driving target value correction section for correcting the driving target value set by the driving target value setting section on the basis of the first and second factors set by the first factor setting section and the second factor setting section; and a motor driver for driving the electric motor on the basis of the driving target value corrected by the driving target value correction section.
