Abstract

The rotation angle detection device of the present invention contains i) a rotation detecting body; ii) a first rotator engaging with the rotation detecting body; iii) a second rotator engaging with the first rotator; iv) a first detector that detects the rotation angle of the first rotator; v) a second detector that detects the rotation angle of the second rotator; and vi) a self-evaluating section. Referencing to the output range of the first and the second signals detected by the first and the second detectors under the normal condition of the rotation detecting body, the self-evaluating section determines, through calculation of the output range of the signals, the normal condition and the abnormal condition ranges. When at least one of the values of the signals is in the abnormal condition range, the self-evaluating section judges that the rotation detecting body is in an abnormal operation.
