PROBLEM TO BE SOLVED: To suppress deterioration in fuel economy at the time of heating by appropriately setting an output distribution between an engine and a MG (a motor generator) and an output distribution between a hot water heater and an electric heater.SOLUTION: System utility function is defined using travel request power of a vehicle, heating request power, generated power by a MG 12 and a generator 17, discharged power by a main battery 18 and a low pressure battery 21 and cooling-water heating power and cooling-water radiating power of an engine 11; and output of the engine 11, output of the MG 12, output of a hot-water heater 22 and output of an electric heater 42 are set so as to maximize the system utility function. This allows an output distribution between the engine 11 and the MG 12 and an output distribution between the hot-water heater 22 and the electric heater 42 to be appropriately set so as to maximize efficiency of a vehicle system as a whole for the purposes of travelling and heating without setting independently the respective output distributions of the travelling (the engine 11 and the MG 12) and the heating (the hot-water heater 22 and the electric heater 42) corresponding to the purposes. |
