To provide a rotary electric machine controller which appropriately distinguishes failure in which a switching device constituting an inverter is in a short circuit state, from the other failure, and thus performs fail-safe control suitable for the inverter.SOLUTION: The rotary electric machine controller is provided with: an inverter controller which generates a switching control signal; and a drive circuit which relays the switching control signal and provides at least diagnostic information of the inverter to the inverter controller. When short circuit information which shows that the switching device is in the short circuit state is included in the diagnostic information, the inverter controller performs active short circuit control ASC. When the short circuit information which shows that the switching device is in the short circuit state is not included in the diagnostic information, and information which shows abnormality other than the switching device being in the short circuit state is included in the diagnostic information, the inverter controller performs shutdown control SD.SELECTED DRAWING: Figure 4

    【課題】インバータを構成するスイッチング素子が短絡状態である故障とその他の故障とを適切に判別して、インバータに対して適切なフェールセーフ制御を実行する。【解決手段】回転電機制御装置は、スイッチング制御信号を生成するインバータ制御装置と、スイッチング制御信号を中継すると共に少なくともインバータの診断情報をインバータ制御装置に提供するドライブ回路とを備える。インバータ制御装置は、診断情報にスイッチング素子が短絡状態であることを示す短絡情報が含まれている場合には、アクティブショートサーキット制御ASCを実行し、診断情報にスイッチング素子が短絡状態であることを示す短絡情報が含まれず、スイッチング素子が短絡状態であること以外の異常を示す情報が含まれている場合には、シャットダウン制御SDを実行する。【選択図】図4
