To provide an engine starting time control device of a hybrid device, which improves the start responsiveness of the vehicle regardless of output insufficiency of a low-voltage power source.SOLUTION: A hybrid vehicle 90 comprises a starter motor 38 that starts an engine 12, a low-voltage power source 40 that supplies electric power to the starter motor 38, a high-voltage power source 42 that supplies electric power to a drive electric motor MG to drive the drive electric motor MG, and an electric oil pump 36 that is driven with the electric power supplied from the low-voltage power source 40. In an engine starting time control device 10 of the hybrid vehicle, in the case where the low-voltage power source 40 simultaneously supplying electric power to the starter motor 38 and the electric oil pump 36 is in an output insufficient state when starting the engine 12, electric power is supplied to the starter motor 38 or the electric oil pump 36 from the high-voltage power source 42 in place of the low-voltage power source 40.SELECTED DRAWING: Figure 1

    【課題】低電圧電源の出力不足に拘らず車両の発進応答性を向上させるハイブリッド車両のエンジン始動時制御装置を提供する。【解決手段】エンジン12を始動するスタータモータ38と、スタータモータ38に電力を供給する低電圧電源40と、駆動用電動機MGに電力を供給して駆動用電動機MGを駆動する高電圧電源42と、低電圧電源40から供給される電力によって駆動される電動オイルポンプ36と、を備えるハイブリッド車両90のエンジン始動時制御装置10であって、エンジン12の始動時において、スタータモータ38および電動オイルポンプ36へ電力を同時供給する低電圧電源40が出力不足状態である場合には、低電圧電源40に替えて、高電圧電源42からスタータモータ38または電動オイルポンプ36に電力が供給される。【選択図】図1
