Zusammenfassung: | To provide a detection device capable of detecting abnormality of a detection section for detecting a physical amount.SOLUTION: A detection device D1 includes a detection sensor 21, a correction section 22 and an abnormality detection section 4. The detection sensor 21 outputs a detection signal according to a physical amount. The correction section 22 corrects a detection signal input from the detection sensor 21 and outputs a detection signal after correcting. The abnormality detection section 4 detects abnormality of the detection sensor 21 or the correction section 22. The correction section 22 includes an offset adjustment part 223 for performing offset adjustment of a detection signal input from the detection sensor 21. The abnormality detection section 4 detects abnormality of the detection sensor 21 or the correction section 22 when there is needed offset adjustment by exceeding an adjustable range by the offset adjustment part 223.SELECTED DRAWING: Figure 1
【課題】物理量を検出する検出部の異常を検出できる検出装置を提供する。【解決手段】本開示の検出装置D1は、検出センサ21、補正部22および異常検出部4を備える。検出センサ21は、物理量に応じた検出信号を出力する。補正部22は、検出センサ21から入力される検出信号の補正を行い、補正後の検出信号を出力する。異常検出部4は、検出センサ21または補正部22の異常を検出する。補正部22は、検出センサ21から入力される検出信号のオフセット調整を行うオフセット調整部223を備える。異常検出部4は、オフセット調整部223による調整可能範囲を超えてオフセット調整が必要である場合に、検出センサ21または補正部22の異常を検出する。【選択図】図1 |
