To provide a motor control device that synchronizes motor drive start timings of a plurality of systems regardless of delay of finish timing of initial check after a plurality of microcomputers are started.SOLUTION: A motor control device comprises a plurality of power converters and a plurality of microcomputers and controls drive of a motor having a plurality of coil groups. After started, the plurality of microcomputers perform initial check for compositional elements of the own system. The plurality of microcomputers inhibit motor drive by a system that has determined to be abnormal in the initial check. When two or more systems have been determined to be normal in the initial check, the plurality of microcomputers start motor drive by synchronizing timings by means of the two or more systems that have been determined to be normal. When only one system has been determined to be normal in the initial check, the plurality of microcomputers start motor drive by means of the one system that has been determined to be normal.SELECTED DRAWING: Figure 8

    【課題】複数のマイコンの起動後、イニシャルチェックの終了タイミングのずれにかかわらず、複数系統のモータ駆動開始タイミングを同期させるモータ制御装置を提供する。【解決手段】モータ制御装置は、複数の電力変換器と、複数のマイコンと、を備え、複数の巻線組を有するモータの駆動を制御する。複数のマイコンは、起動後に、自系統の構成要素についてイニシャルチェックを実施する。複数のマイコンは、イニシャルチェックで異常判定された系統によるモータ駆動を禁止する。また、複数のマイコンは、イニシャルチェックで二つ以上の系統が正常判定されたとき、正常判定された二つ以上の系統でタイミングを同期させてモータ駆動を開始する。また、複数のマイコンは、イニシャルチェックで一つの系統のみが正常判定されたとき、正常判定された一つの系統でモータ駆動を開始する。【選択図】図8
