To provide a steering controller capable of performing a more proper initial inspection.SOLUTION: When a drop in an own power supply voltage is detected, a pre-driver transmits an abnormality detection signal to a microcomputer, resets an own configuration to an initial configuration designated prior to initialization, and suspends the operation. When the abnormality detection signal transmitted from the pre-driver is received, the microcomputer resumes an initial check including initialization of the pre-driver. In a process of performing the initial check, the microcomputer detects a short-circuit fault between a gate and source of an FET of a power supply on the basis of a voltage between the gate and source of the FET of the power supply with the FET of the power supply of an inverter turned on (step S203). When the short-circuit fault between the gate and source of the FET of the power supply is detected during the initial check, the microcomputer does not permit initiation of implementation of assist control, that is, initiation of power feed to a motor.SELECTED DRAWING: Figure 5

    【課題】より適切な初期検査を行うことができる操舵制御装置を提供する。【解決手段】プリドライバは、自己の電源電圧の低下が検出されるとき、異常検出信号をマイクロコンピュータへ送信し、自己の設定状態を初期設定前の初期状態にリセットして動作を停止する。マイクロコンピュータは、プリドライバからの異常検出信号が受信されるとき、プリドライバの初期設定を含むイニシャルチェックをやり直す。マイクロコンピュータは、イニシャルチェックの実行過程において、インバータにおける電源側のFETをオンした状態における電源側のFETのゲートとソースとの間の電圧に基づき、電源側のFETのゲートとソースとの間の短絡故障を検出する(ステップS203)。マイクロコンピュータは、イニシャルチェックにおいて電源側のFETのゲートとソースとの間の短絡故障が検出されるとき、アシスト制御の実行開始、すなわちモータへの給電開始を許可しない。【選択図】図5
