PROBLEM TO BE SOLVED: To provide a method of controlling a hybrid vehicle including an internal combustion engine supercharged by a turbocharger during a gear change stage which has no weak points of the prior art, is easily implemented, and has high cost-effectiveness.SOLUTION: A method of controlling a hybrid vehicle includes: a stage of recognizing interruption in transmission of torque C to driving wheels during gear change with the open position of a servo support type clutch; a stage of calculating target torque which should be supplied to the driving wheels at a time point twhere interruption in transmission of the torque C to the driving wheels is recognized during gear change with the open position of the servo support type clutch; and a stage of controlling a reversible type electric machine so as to supply the target torque to the driving wheels at the time point twhere the interruption in transmission of the torque C to the driving wheels is recognized during gear change with the open position of the servo support type clutch and until a time point tof recognizing a state in which a turbocharger has the same efficiency as the efficiency of the time point twhere interruption in transmission of the torque C to the driving wheels is recognized during gear change. 【課題】変速段階中に、ターボチャージャにより過給される、内燃機関を備えるハイブリッド車両の制御方法であって、従来技術の欠点がなく更に実施するのに容易で且つ費用効果のある、方法を提供する。【解決手段】サーボ支援型クラッチの開位置により、変速時に駆動輪へのトルクＣの伝達の中断を認識する段階と、サーボ支援型クラッチの開位置により、変速時に駆動輪へのトルクＣの伝達の中断が認識される、時点ｔ1において、駆動輪に供給されるべき、目標トルクを算出する段階と、サーボ支援型クラッチの開位置により、変速時に駆動輪へのトルクＣの伝達の中断が認識される、時点ｔ1において、及び変速時に駆動輪へのトルクＣの伝達の中断が認識される、時点ｔ1の効率と同じ効率をターボチャージャが有する、状態を認識する、時点ｔ2まで、駆動輪に目標トルクを供給するように、可逆式電気機械を制御する段階を具備する方法を提供する。【選択図】図１
