The output of an engine is recovered by a generator. A motor is driven by the electric power generated by the generator. When there is a sudden acceleration, etc., the generation power output by the generator is delayed, and when the electric power supplied to the motor is insufficient, the insufficient part is supplied from a battery. The maximum power output of the battery decreases according to battery temperature. However, as the response of the generation power output of the generator is increased if battery temperature is low, the above-mentioned insufficient part is always suppressed below the maximum power output of the battery. In this way, the inability of the battery to supply electric power required for acceleration is prevented, and thus the problem of poor acceleration is eliminated.

1. A control device for a vehicle, wherein the vehicle comprises:an engine; a generator which rotates in synchronism with the engine, and regenerates the output of the engine; a motor driven by the electric power regenerated by the generator, and an electric energy storage device which supplies electric power to the motor, wherein when the electric power supplied to the motor from the generator is insufficient due to response delay of the generation power output from the generator, the electric power to cover the insufficient amount is supplied to the motor from the electric energy storage device, and the control device comprises: a sensor which detects the temperature of the electric energy storage device, and a microprocessor programmed to enhance the response of the generation power output of the generator according to the decline of the temperature of the electric energy storage device.
