Abstract
A vehicle air conditioner has a non-contact temperature sensor for detecting a surface temperature of a detection range of a passenger compartment. The detection range includes a first detection portion in which a surface temperature is changed to approximately correspond to an inside air temperature, a second detection portion in which a surface temperature is changed in accordance with an outside air temperature, and a third detection portion in which a surface temperature is changed in accordance with a sunlight amount entering the passenger compartment. In the vehicle air conditioner, a target temperature of air blown into the passenger compartment is calculated based on a set temperature and a surface temperature from the non-contact temperature sensor, while air-conditioning performance is improved.
