Zusammenfassung:	To downsize an electric oil pump device while enabling an engine to be started up with a starter motor.SOLUTION: When starting up an engine with a starter motor, starter start-up control allowing an electric oil pump device to start discharging operating oil is performed after determining that output voltage of a power source device or of input voltage of an electric oil pump device is equal to or larger than predetermined voltage at completion of cranking of the starter motor. Thus, a vehicle control device enables the electric oil pump device to normally perform, even in a case where the output voltage of the power source device is declined along with the cranking, without using a high functional device operational when voltage is low in the electric oil pump device and thereby being capable of downsizing the electric oil pump device while enabling an engine to be started up with a starter motor.SELECTED DRAWING: Figure 5 【課題】スタータモータを用いたエンジンの始動に対応しつつ、電動オイルポンプ装置の小型化を図る。【解決手段】スタータモータを用いたエンジンの始動に際して、スタータモータによるクランキングの完了後に電源装置の出力電圧又は電動オイルポンプ装置の入力電圧が所定電圧以上となっていると判定した後に、電動オイルポンプ装置による作動油の吐出を開始するスタータ始動制御が行われるので、クランキングに伴って電源装置の出力電圧が低下する場合に、電動オイルポンプ装置の内部に電圧低下時にも作動可能な高機能なデバイスを使用することなく、電動オイルポンプ装置を正常に作動することができる。よって、スタータモータを用いたエンジンの始動に対応しつつ、電動オイルポンプ装置の小型化を図ることができる。【選択図】図５
