Abstract
In a vehicle air conditioner where a foot mode and a foot/defroster mode can be set, when a target temperature of air blown into a passenger compartment is higher than a predetermined temperature, the foot mode is selected. However, even if the target temperature of air is higher than the predetermined temperature, the foot/defroster mode is selected in place of the foot mode when an outside air temperature is lower than a predetermined temperature and when a vehicle speed is higher than a predetermined speed. In the vehicle air conditioner, because the foot/defroster mode can be suitably automatically selected based on a fog-generation condition of a windshield, both fog-preventing performance of the windshield and heating performance of the passenger compartment are improved during heating operation.
