PROBLEM TO BE SOLVED: To provide an internal combustion engine start control device for a hybrid vehicle capable of inhibiting a troublesome change in a gear shift stage at start of an internal combustion engine.SOLUTION: In an internal combustion engine start control device for temporarily changing engine speed at start of an internal combustion engine 2 by using at least one of a power division mechanism 5 and an automatic transmission 10, a change duration when a state where the engine speed has been changed is continued at start of the internal combustion engine 2 is determined, and the necessity of the change in the engine speed by using the change of the gear shift stage of the automatic transmission 10 is determined in accordance with the operation point change amount and the change duration at start of the internal combustion engine 2.SELECTED DRAWING: Figure 1

    【課題】内燃機関の始動時に煩雑な変速段の変更を抑制できるハイブリッド車両の内燃機関始動制御装置を提供する。【解決手段】動力分割機構5及び自動変速機10の少なくとも一つを利用して内燃機関2の始動時にエンジン回転数を一時的に変更する内燃機関始動制御装置において、内燃機関2の始動時にエンジン回転数が変更された状態が続く変更継続時間を決定し、自動変速機10の変速段の変更を利用したエンジン回転数の変更の要否を、内燃機関2の始動時における動作点変更量と変更継続時間とに応じて決定する。【選択図】図1
