<P>PROBLEM TO BE SOLVED: To provide a driving control method for a compressor for preventing noise caused by the low delivery capacity and low coolant flow rate of the compressor of an air conditioning device for an automobile. <P>SOLUTION: The compressor of the air conditioning device for an automobile includes a cylinder bore compressing coolant, a piston inserted in the cylinder bore, a swash plate of which the inclination angle to the driving shaft is adjusted, and a control valve adjusting the inclination angle of the swash plate. The compressor control method includes a step of controlling the delivery capacity of the compressor to the predetermined value when the predetermined conditions, such as vehicle speed and acceleration ratio are satisfied, and it is determined that the compressor enters a low coolant flow rate state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
