Abstract
In a vehicle air conditioner, a first air-conditioning control value is calculated based on a surface temperature detected by a non-contact temperature sensor in a temperature detection area of a passenger compartment. When it is determined that an obstacle exists between the temperature detection area and the non-contact temperature sensor, a second air-conditioning control value is calculated according to a temperature information that is influenced less by the obstacle than the detected surface temperature. When it is determined that the obstacle does not exist, an air conditioning state of the passenger compartment is controlled based on the first air-conditioning control value. When it is determined that the obstacle exists, the first air-conditioning control value is corrected to approach the second air-conditioning control value to calculate a corrected air-conditioning control value, so that the air conditioning state can be controlled satisfactorily.
