When a battery control unit allows use of the electric compressor, an air conditioning control unit performs air-conditioning of a cabin in such a manner that the air conditioning control unit controls the electric compressor to be operated. When the battery control unit prevents use of the electric compressor, the air conditioning control unit controls the electric compressor to be stopped. In addition, the air conditioning control unit heats a windshield in such a manner that the air conditioning control unit controls a window heater to be operated. Accordingly, even when the electric compressor is stopped, fogging of the windshield is suppressed. The air conditioning control unit does not give an excessive feeling of discomfort or unease to a user, because the air conditioning control unit continuously performs a normal air-conditioning control. Fogging of the windshield can be suppressed in a state where power consumption relative to a battery is suppressed.
