To suppress a situation where a motor generator cannot receive an engine rotation output anymore in a hybrid vehicle.SOLUTION: A control method of a hybrid vehicle having a power mode includes: setting a limit value of a system voltage applied to a motor generator on the basis of a predetermined parameter; and (B) prohibiting selection of the power mode when the limit value of the system voltage is lower than a threshold.SELECTED DRAWING: Figure 3 【課題】ハイブリッド車両において、モータジェネレータがエンジン回転出力を受け止めきれなくなるような事態を抑制する。【解決手段】パワーモードを備えるハイブリッド車両の制御方法は、（Ａ）モータジェネレータに印加されるシステム電圧の制限値を所定のパラメータに基づいて設定することと、（Ｂ）システム電圧の制限値が閾値よりも低い場合、パワーモードの選択を禁止することと、を含む。【選択図】図３
