AIR CONDITIONING SYSTEM FOR VEHICLE

摘要

An air conditioning system for a vehicle includes a volume control means capable of controlling a discharge of a variable volume compressor (22,100) by regulating the opening of a volume control valve (200) through regulating driving currents supplied to the volume control valve (200), a means for predicting a change in the rotational speed of the variable volume compressor (22,100), and a means for controlling the driving torque for the variable volume compressor (22,100) transmitted from the vehicle engine before the change in the rotational speed of the variable volume compressor (22,100) begins when the predicted change in the rotational speed of the variable volume compressor (22,100) exceeds a threshold value.
