Abstract
A vehicle air conditioner controls the air-conditioning automatically based on sensors detecting environmental conditions regarding the air-conditioning of a vehicle and based on an operational portion operable by a passenger. One of the sensors is a sunlight sensor for detecting the amount of sunlight incident into the vehicle. A signal detected by the sunlight sensor is modified to have a time constant by a time constant process. The modification is based on the elevation angle of the sunlight and the inside air temperature of the vehicle. The modified signal is used for automatic control of the air-conditioning.
