Abstract: A rotation angular speed detection apparatus that accurately detects a low rotation angular speed of a rotating body includes: a receiving part for receiving rotation angles at predetermined time intervals from a rotation angle sensor that detects rotation angles of a rotating body; a storage part for storing received rotation angles; and a control part. When the difference between a first arbitrary angle stored and a second angle stored before the first angle is less than a predetermined value, the control part determines, from the stored rotation angles, a third angle in which a difference between the first angle and the third angle is more than the predetermined value, and the control part divides the difference between the first angle and the third angle by the time required from storing of the third angle to storing of the first angle to detect a rotation angular speed.

The first and second detection signals have constant amplitudes, have the same periods, and have wavelengths which are output of phase. The controlling section compares the amplitude values of most recent first and second detection signals output from the rotation detecting section, and determines whether or not the amplitude values fall within proper ranges. When the controlling section determines that they fall within the proper ranges, a piece of detection information which is created based on the most recent first and second detection signals is supplied to a controller.
