Summary:To provide a steering control device which can suppress such a situation that torque that can be output by a motor is not restricted in a case where an abnormality in a power source is detected.SOLUTION: A steering control device is connected to a main power source via a power source device having an auxiliary power source. The steering control device includes a turning side control unit which controls the operation of a turning side motor by controlling the drive of a drive circuit connected to at least one of the main power source and the auxiliary power source. The connection state of the drive circuit to the main power source and the auxiliary power source is switched by the power source device so as to shift to the backup state with detection of a fall of the main power source. The turning side control unit is configured to start output restriction processing in the shift of backup until switching of the connection state by the power source device so as to shift to the backup state with detection of the fall is completed after detection of the fall of the main power source.SELECTED DRAWING: Figure 6 【課題】電源の異常が検出される場合において、モータでの出力可能なトルクが制限されない状況に陥り難くすることができる操舵制御装置を提供する。【解決手段】操舵制御装置は、主電源に対して、補助電源を有する電源装置を介して接続されている。操舵制御装置は、主電源及び補助電源の少なくともいずれかに接続される駆動回路の駆動を制御することで転舵側モータの動作を制御する転舵側制御部を備えている。主電源及び補助電源に対する駆動回路の接続状態は、主電源の失陥を検出することに伴ってバックアップの状態に遷移するように電源装置によって接続状態が切り替えられるものである。そして、転舵側制御部は、主電源の失陥の検出後、当該失陥の検出に伴ってバックアップの状態へ遷移するように電源装置による接続状態の切り替えが完了するまでの間にバックアップの遷移時の出力制限処理を開始するように構成されている。【選択図】図6
