Abstract:
A rotation detection device includes a plurality of detectors each including a plurality of calculators respectively calculating a detection value. A control unit of the rotation detection device monitors abnormality of detection values respectively detected by the plurality of detectors, and, when determining abnormality, identifies a calculator calculating an abnormal detection value based on a result of comparison between the detection values of the plurality of calculators. Then, the control unit continues calculation of an absolute angle by using the detection values from the calculators other than the identified calculator.
