Abstract
An ECU detects a steering angle that is an absolute angle based on a sine signal and a cosine signal that are output from a steering sensor. The ECU includes a three-phase pulse generator that generates, based on the sine signal and the cosine signal, three-phase pulse signals that have edges corresponding to predetermined rotational angles and that are set in such a manner that the predetermined rotational angles corresponding to the respective edges do not overlap each other and are at regular intervals. A microcomputer has a function as a second rotational angle detector that calculates a steering angle based on the pulse signals.
