Abstract
It is an object of the present invention to make steering characteristics excellent in a small current region by correcting voltage in the small current region. A control apparatus of an electric power steering apparatus for feedback controlling operation of a motor by a microcomputer based on a current value of the motor detected by a current detector, wherein an arbitrary function detector of current detection characteristics is provided between a current detection amplifier of the current detector and the microcomputer, and motor current detection characteristics are corrected.
