To provide a power generation source control device which more improves practical fuel consumption.
The power generation source control device successively compares electric power which is used for EV traveling (available electric energy) with the estimated value (estimated required electric energy) of required electric energy when traveling by an EV travel mode to the destination (S14), sets a power threshold at 7.5 kw when the estimated required electric energy is larger, and sets the power threshold at 30 kw, when the available electric energy is larger. Then the power generation source control device switches the electric travel mode in which the vehicle is travelled using motor generator MG as a power generation source travel mode supplying power from a battery 6, and an HV travel mode using an engine 2 as a power generation source, based on comparison of the sequentially decided driving power request value with the power threshold.
