Abstract
A vehicle includes an engine, a generator driven by the engine to generate an electric power, and a high-voltage battery charged with the electric power. An air heating in a vehicle interior is implemented by waste heat of the engine through which a heat medium is circulated and heated, and an air heating in the vehicle interior is implemented by a heat pump device consuming the electric power of the electric storage device. A hybrid ECU performs air conditioning control, and includes a determination device that determines whether to implement the air heating by the waste heat or the air heating by the heat pump device based on an engine body temperature, and a heating control device that selectively implements the air heating by the waste heat and the air heating by the heat pump device based on a determination result of the determination device.
