PROBLEM TO BE SOLVED: To suppress reduction of fuel economy of an internal combustion engine, in a plug-in hybrid system capable of performing battery charging amount increasing control.SOLUTION: In a plug-in hybrid system capable of performing battery charging amount increasing control for driving an electric generator by engine power during warming-up operation and charging electric power generated by the electric generator to a battery, performance of the battery charging amount increasing control during the warming-up operation is prohibited when a battery charging amount at a start time of warming-up operation is a first electric storage amount or more, when a battery charging amount at a completion time of warming-up operation when the battery charging amount increasing control has been performed during the warming-up operation is predicted to be a second electric storage amount or more, or when a battery electric storage amount at the completion time of warming-up operation when the battery charging amount increasing control has not been performed during the warming-up operation is predicted to be a third electric storage amount or more. |
