Abstract
A vehicle air conditioner includes a non-contact temperature sensor for detecting a temperature in a predetermined area of a passenger compartment in non-contact, an air conditioning unit that controls an air conditioning state in the passenger compartment based on at least the temperature detected by the non-contact temperature sensor, and an air conditioning ECU for controlling the air conditioning unit. The ECU determines whether the temperature detected by the non-contact temperature sensor is abnormal, and informs a determination result to a user by using a light emitting diode. Thus, it is possible to notify the user whether the temperature detected by the non-contact temperature sensor is abnormal. The determination whether the detected temperature of the non-contact temperature sensor is abnormal can be performed by using at least one of the temperature detected by the non-contact temperature sensor and an environment condition.
