To provide an engine start control device of a hybrid vehicle in which a motor travel area is secured.SOLUTION: An engine start control device of a hybrid vehicle in which a clutch, a motor and an automatic transmission are installed in the order from the engine side to the drive wheel side on a power transmission path between the engine and the drive wheel includes: a start request determination part which determines whether a request torque to the hybrid vehicle becomes equal to or greater than a starting threshold for starting the engine during travel with the motor in such a state that the engine is stopped and the clutch is released; and a start control part which executes upshift start processing of starting the engine via the clutch by utilizing an inertia torque that increases due to execution of upshift of the automatic transmission when affirmative determination is made by the start request determination part.SELECTED DRAWING: Figure 2

    【課題】モータ走行領域を確保したハイブリッド車両のエンジン始動制御装置を提供することを課題とする。【解決手段】エンジンと駆動輪との間の動力伝達経路上に前記エンジン側から前記駆動輪側に順にクラッチ、モータ、及び自動変速機が設けられたハイブリッド車両のエンジン始動制御装置において、前記エンジンが停止し前記クラッチが解放した状態での前記モータによる走行中に、当該ハイブリッド車両への要求トルクが前記エンジンを始動させる始動閾値以上となったか否かを判定する始動要求判定部と、前記始動要求判定部により肯定判定がなされた場合に、前記自動変速機のアップシフトの実行により増大するイナーシャトルクを利用して前記クラッチを介して前記エンジンを始動するアップシフト始動処理を実行する始動制御部と、を備えたハイブリッド車両のエンジン始動制御装置。【選択図】図2
