Abstract
A detection signal correction method includes: calculating a rotation angle of a rotation shaft of a motor, based on a detection signal of a sensor; calculating a steering velocity of a steering shaft based on the rotation angle; calculating an error of the detection signal; and correcting the error of the detection signals when the steering velocity is equal to or greater than a steering velocity threshold value and the error of the detection signal is equal to or greater than an error threshold value.
