PROBLEM TO BE SOLVED: To provide a restart control system of an engine, a hybrid vehicle and a restart control method of the engine, capable of reducing a load to a motor by reducing start torque necessary for the motor to supply by comparatively simple control.SOLUTION: When an engine 10 is stopped in inertia travel of a vehicle, and further when a restart request signal of the engine 10 is received, power is supplied to the engine 10 from a motor generator 31, and restart compensation control is implemented as control for temporarily switching a clutch 14 from a disconnected state to a half-connected state to keep the half-connected state in which power is transmitted to the engine 10 from a driving wheel 24 through a differential 23, a propeller shaft 22 and a clutch 14 for a predetermined set time t, and returning the clutch 14 from the half-connected state to the disconnected state.SELECTED DRAWING: Figure 1 【課題】比較的簡単な制御で、モーターが供給する必要のある起動トルクを減少して、モーターへの負荷を軽減することができるエンジンの再始動制御システム、ハイブリッド車両及びエンジンの再始動制御方法を提供する。【解決手段】車両が惰性走行時で、かつ、エンジン１０が停止している場合に、さらに、エンジン１０の再始動要求信号を受信したときに、モータージェネレーター３１からエンジン１０に動力を供給するとともに、クラッチ１４を一時的に断状態から半接状態に切り替えて、駆動輪２４からデファレンシャル２３、プロペラシャフト２２、クラッチ１４を介してエンジン１０に動力を伝達する半接状態を予め設定した設定時間ｔの間維持した後に、クラッチ１４を半接状態から断状態に戻す制御である再始動補助制御を行う。【選択図】図１
