Abstract
In a vehicle air conditioner having a variable displacement compressor, a control unit calculates a target cooling temperature of air to be cooled by an evaporator, and controls a discharge capacity of the compressor such that a detected air temperature of the evaporator approaches the target cooling temperature. When a deceleration running state of the vehicle is detected, the control unit sets a corrected target cooling temperature lower than the target cooling temperature by a predetermined temperature, and controls the discharge capacity of the compressor such that the detected air temperature approaches the corrected target cooling temperature when the detected air temperature is lower than the corrected target cooling temperature, or controls the discharge capacity of the compressor approximately at the maximum capacity regardless of the corrected target cooling temperature when the detected air temperature is not lower than the corrected target cooling temperature.
