PROBLEM TO BE SOLVED: To lessen engine load caused by operating a generator, in order to reduce fuel consumption by preserving electric power of a first power supply used for starting an engine or running a vehicle and by reducing charged capacity for the first power supply, and to improve the efficiency of regenerative operation of the generator by making a second power supply collect deceleration energy that hag not been utilized conventionally and by utilizing generation (regeneration) in the deceleration of the vehicle that does not require fuel, in a power generation control device for a vehicle. SOLUTION: This device is provided with a deceleration-detecting means, that detects the decelerating state of the vehicle; a first power supply, a main power supply for the vehicle, that is normally connected to the generator; a second power supply, an auxiliary power supply for the vehicle, that is connectable to the generator, only when conditions of connecting to this power supply are satisfied; and a switching means, that connects the second power supply to the generator when the vehicle is decelerated or the capacity of the second power supply, is larger than a given value. |
