Abstract: A vehicle air conditioner is controlled to a target control value that controls a swash-plate control value of a swash-plate variable capacity compressor. The variable control is based on temperature deviation between target evaporator temperature and actual evaporator temperature, to control compressor discharge capacity. A target evaporator temperature is set. Deviation between the target evaporator temperature and actual evaporator temperature is calculated. Control coefficients are variably set according to the magnitude of the temperature deviation. A target control value of a pressure control valve of the swash-plate variable capacity compressor is calculated using the control coefficients. The pressure control valve is controlled by the target control value.
