【課題】早い応答性と燃費の向上を両立できるハイブリッド車両を提供する。【解決手段】ハイブリッド車両は、車両の要求駆動力に基づいてエンジンの休筒運転の要否を判断する休筒運転要否判断部を備える。休筒運転が不要と判断された場合、第１クラッチを切断してＥＶ走行で走行可能であり、休筒運転が必要と判断された場合、エンジンを休筒運転で運転すると共に第１クラッチを連結する。【選択図】図７ The present invention provides a hybrid vehicle driving system in which quick response and improvement in fuel economy are compatible. A hybrid vehicle driving system 1 of the invention includes a cylinder deactivated operation necessity determination unit for determining the necessity of a cylinder deactivated operation of an engine 6 when a required driving force required on a vehicle is smaller than a driving force of the engine 6 that runs in the cylinder deactivated operation. When the cylinder deactivated operation is determined to be unnecessary by the cylinder deactivated operation necessity determination unit, the vehicle can be driven in an EV driving by disengaging a first clutch 41 and a second clutch 42, whereas when the cylinder deactivated operation is determined to be necessary by the cylinder deactivated operation necessity determination unit, the engine 6 runs in the cylinder deactivated operation and at least one of the first clutch 42 and the second clutch 42 is engaged.
