ABSTRACT:
A control system is provided for a hybrid vehicle including an internal combustion engine, a drive shaft driven by the engine, a generator for converting kinetic energy of the drive shaft to electrical energy to generate electric power, and an electrical storage device for storing electrical energy output from the generator. Deceleration of the engine is detected. Supply of fuel to the engine is interrupted during the deceleration of the engine. An amount of intake air supplied to the engine is controlled such that the amount of intake air supplied to the engine is increased when the generator regenerates electrical energy during the deceleration of the engine. Calculation is made of an amount of electrical energy to be regenerated by the generator during the deceleration of the engine. An output from the generator is controlled based on the amount of electrical energy calculated.
