To provide a rotation detector with which, even when there is occurrence of abnormality in the number of rotations detected in accordance with the rotation of a detection object, it is possible to keep the computation of rotation information continuing while suppressing adverse effects on a drive object due to the abnormality of the number of rotations, and a steering system equipped with this rotation detector.SOLUTION: A first control unit 60 of a rotation detector 41 monitors the presence of abnormality in the computed number of rotations on the basis of a prescribed angle of rotation and the number of rotations computed by rotations computation units 54a, 54b. When it is determined that there is occurrence of abnormality in the number of rotations in the self system, first and second control units 60, 61 output the rotation information computed by a second control unit 61 of an other system different from the self system.SELECTED DRAWING: Figure 3
【課題】検出対象の回転に応じて検出される回転回数に異常が生じている場合でも、回転回数の異常による駆動対象に対する悪影響を抑制しつつ、回転情報の演算を継続させることが可能な回転検出装置、及びこの回転検出装置を備える操舵システムを提供する。【解決手段】回転検出装置41の第1制御部60は、所定の回転角と、回数演算部54a,54bにより演算された回転回数とに基づいて、演算された回転回数の異常の有無を監視する。第1,第2制御部60,61は、自系統の回転回数に異常が生じていると判定した場合に、自系統とは異なる他系統の第2制御部61により演算された回転情報を出力する。【選択図】図3
