To provide a recognition error detection device capable of detecting a recognition error of a rotation angle acquisition device.SOLUTION: When a rotation angle acquisition device includes a data processing unit that acquires a relative rotation angle of an electric motor on the basis of a received value output from a rotation angle sensor and acquires an absolute rotation angle, there is a case in which the rotation angle sensor is normal, however, in the data processing unit, the value output from the rotation angle sensor is recognized as a different value, and a recognition error occurs. The relative rotation angle (a direction and a size) acquired in the data processing unit is different from an actual relative rotation angle, and the absolute rotation angle is different from the actual absolute rotation angle. Therefore, on the basis of the absolute rotation angle acquired by the rotation angle acquisition device or a change state of the absolute rotation angle, the recognition error can be detected satisfactorily.SELECTED DRAWING: Figure 11

    【課題】回転角取得装置の認識エラーを検出可能な認識エラー検出装置を提供する。【解決手段】回転角取得装置が、回転角センサから出力されて、受信した値に基づいて電動モータの相対回転角を取得して、絶対回転角を取得するデータ処理部を含む場合において、回転角センサは正常であるが、データ処理部において、その回転角センサから出力された値が異なる値に認識され、認識エラーが生じる場合がある。データ処理部において取得された相対回転角(向き、大きさ)が実際の相対回転角と異なり、絶対回転角が実際の絶対回転角と異なる。以上のことから、回転角取得装置によって取得された絶対回転角や絶対回転角の変化状態に基づけば、認識エラーを良好に検出することができる。【選択図】 図11
