Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle capable of shortening time to completion of starting while avoiding power shortage of electrical components at the time of starting of an internal combustion engine accompanying fuel heating.SOLUTION: A control device of the present invention performs control in which, when fuel heating is required at the time of starting of an internal combustion engine 2, fuel is injected while the internal combustion engine 2 is being cranked by a first motor generator 3 and while the fuel is heated by a glow plug 5. When a voltage supplied by a battery 15 for auxiliary equipment becomes lower than a predetermined value during the fuel heating by the glow plug 5, energization of the glow plug 5 is cut off, and the cranking of the internal combustion engine 2 by the first motor generator 3 is continued and the fuel injection is interrupted. Then, when the voltage of the battery 15 for the auxiliary equipment exceeds a determination value, the fuel heating and the fuel injection are resumed.SELECTED DRAWING: Figure 1 【課題】燃料加熱を伴う内燃機関の始動時における電装品の電力不足を回避しつつ始動完了までの時間を短縮できるハイブリッド車両の制御装置を提供する。【解決手段】本発明の制御装置は、内燃機関２の始動に際して燃料加熱が必要な場合、第１モータ・ジェネレータ３にて内燃機関２をクランキングしながらグロープラグ５にて燃料を加熱しつつ燃料噴射を行う。グロープラグ５による燃料加熱中に補機用バッテリ１５が供給する電圧が所定値未満となった場合、グロープラグ５の通電を遮断するとともに第１モータ・ジェネレータ３による内燃機関２のクランキングを継続し、かつ燃料噴射を中断する。そして、補機用バッテリ１５の電圧が判定値以上になった場合燃料加熱及び燃料噴射を再開する。【選択図】図１
