Patent ID: 7272944

Claim:
An air conditioner for a vehicle, comprising: a non-contact temperature sensor that detects a temperature in a predetermined area of a passenger compartment in non contact; a control unit that controls an air state in the passenger compartment based on at least the temperature detected by the non-contact temperature sensor; determining means for determining whether or not the temperature detected by the non-contact temperature sensor corresponds to an actual temperature of the passenger compartment; notifying means for notifying a passenger whether the temperature detected by the non-contact temperature sensor does not correspond to the actual temperature of the passenger compartment; an outside air temperature sensor for detecting a temperature of outside air of the passenger compartment; and a water temperature sensor for detecting a temperature of water for cooling a vehicle engine; wherein even when the temperature detected by the non-contact temperature sensor does not correspond to the actual temperature of the passenger compartment, the notifying means does not notify a passenger in the passenger compartment when the temperature of outside air detected by the outside air temperature sensor is lower than a predetermined air temperature; and even when the temperature detected by the non-contact temperature sensor does not correspond to the actual temperature of the passenger compartment, the notifying means does not notify a passenger in the passenger compartment when the temperature of outside air detected by the outside air temperature sensor is lower than the predetermined air temperature and when the temperature of water detected by the water temperature sensor is lower than a predetermined water temperature.
