Summary:PROBLEM TO BE SOLVED: To provide an apparatus enabling size and cost reduction of an element constituting reserve charging-means used for charging a capacitor, and prevention of deterioration in performance of controlling a load.SOLUTION: An apparatus performs: introducing a voltage of a battery detected by detection means (step S2) after an ignition key is turned on (Yes for step S1); reading charging time of a capacitor, the time corresponding to the detected voltage from memory (step S3); turning on a relay by a control part (step S5) when elapsed time, measured by a timer, from turning on of the ignition key exceeds the read charge time (Yes for step S4) to start power feed from the battery to a drive circuit; and supplying a power-steering motor with a given drive current, thus outputting assist torque. 【課題】コンデンサを充電する予備充電手段を構成する素子を小型化でき、低コストでしかも負荷の制御性能の悪化を防止できる装置を提供する。【解決手段】イグニッションキーのオンの後(ステップS1のYES)、検出手段によるバッテリの検出電圧が取り込まれ(ステップS2)、その検出電圧に対応するコンデンサの充電時間が、メモリから読み出され(ステップS3)、タイマにより計時されるイグニッションキーのオンからの経過時間が、読み出された充電時間を超えると(ステップS4のYES)、制御部によりリレーがオンされ(ステップS5)、バッテリから駆動回路への給電が開始され、パワステモータに所定の駆動電流が供給されて補助トルクが出力される。【選択図】図3
