To provide an angle calculation device capable of improving reliability of calculation of an absolute angle; and to provide a steering apparatus.SOLUTION: A first operational circuit includes a counter BIST part for diagnosing a counter abnormality detection part, and a power supply BIST part for diagnosing a voltage abnormality detection part. A second operational circuit includes a first absolute angle information BIST part for diagnosing a first absolute angle information abnormality detection part, and a second absolute angle information BIST part for diagnosing a second absolute angle information abnormality detection part. A third operational circuit includes an absolute angle BIST part for diagnosing an absolute angle abnormality detection part. Execution timings of diagnosis by each BIST part (the counter BIST part, the power supply BIST part, the first absolute angle information BIST part, the second absolute angle information BIST part and the absolute angle BIST part) are different mutually.SELECTED DRAWING: Figure 7
【課題】絶対角の演算の信頼性を向上させることのできる角度演算装置及び転舵装置を提供する。【解決手段】第1演算回路は、カウンタ異常検出部を診断するカウンタBIST部、及び電圧異常検出部を診断する電源BIST部を備えている。第2演算回路は、第1絶対角情報異常検出部を診断する第1絶対角情報BIST部、及び第2絶対角情報異常検出部を診断する第2絶対角情報BIST部を備えている。第3演算回路は、絶対角異常検出部を診断する絶対角BIST部を備えている。各BIST部(カウンタBIST部、電源BIST部、第1絶対角情報BIST部、第2絶対角情報BIST部、及び絶対角BIST部)の診断の実行タイミングは、互いに異なる。【選択図】図7
