ABSTRACT:
A hybrid vehicle can be driven using both of respective driving forces from an engine and a motor. A heating mechanism of an air conditioning apparatus uses thermal energy from cooling water of the engine to heat the interior of a passenger compartment. An ECU takes into consideration engine efficiency from the standpoint of fuel economy enhancement to primarily determine the driving force share ratio between the engine and the motor. Further, the ECU calculates a preset temperature corresponding to a cooling water temperature necessary for desired heating as well as a control target temperature in which the preset temperature is reflected, and corrects the primarily determined driving force share ratio to increase the share of the driving force of the engine by an amount according to a deviation between the cooling water temperature measured by a water temperature sensor and the control target temperature. Heating performance can thus be ensured promptly without deterioration of fuel economy.
