Abstract
The rotation angle detection device detects the rotation angle of a rotary member by employing, at the least, either a sine wave signal or a cosine wave signal that is generated as the rotary member is rotated, and employs a change per unit time in the sine wave signal or cosine wave signal to determine whether an output abnormality has occurred in the rotation angle detection device. Further, this rotation angle device is employed to detect the motor angle of an electric power steering apparatus.
