A gas-sparing vehicle is achieved by a control system for a hybrid vehicle equipped at least with: a hybrid engine which includes at least a first rotary electric unit for deciding the rpm of the engine and a second rotary electric unit for deciding the driving force of the vehicle and which has power converting means connected to the output shaft of the engine; and electricity storing means. In one embodiment, a hybrid controller 16 controls the drive of a first rotary electric unit 2000 according to a startup torque command value which is decided based on the rpm of an engine at the time of engine startup and which decreases as the rpm increases; it also determines that the complete explosion in an engine 1 has occurred when the startup torque command value falls below a predetermined complete explosion judgment value.
