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: After EG output (output of an engine 11) and MG output (output of a MG 12) are set based on travel request power, HP output corresponding to the MG output is set on an optimum HP output distribution line connecting the HP output (output of an electric heater 42) maximizing system utility function to the MG output; and HC output (output of a hot-water heater 22) is set by subtracting the HP output from heating request power. This allows the HC output and the HP output to be set so as to maximize the system utility function for the EG output and the MG output, where the system utility function is defined using the travel request power, the heating request power, generated power, discharged power, cooling-water heating power, cooling-water radiating power and fuel consumption power. |
