Apparatus and method of controlling compressor of air conditioning device of vehicle

An apparatus for controlling a compressor of an air conditioning device of a vehicle, the apparatus comprising:

• an operation information detector which detects operation information from various sensos according to an operation of the vehicle;
• the compressor which compresses a refrigerant for operating an air conditioner of the air conditioning device;
• and
• a controller which performs starting acceleration control of momentarily decreasing an operation rate of the compressor, which uses engine power in an acceleration situation of the vehicle,
• wherein the controller stores a first map, in which a starting acceleration entry condition according to a driving pattern and a heat load of the vehicle is defined in a plurality of levels, sets a starting acceleration entry condition having a final level corresponding to the driving pattern according to a starting acceleration entry frequency of a driver for a predetermined unit time within a limited level range of the first map, which is determined based on the heat load of the vehicle, and adjusts a starting acceleration control frequency of the compressor,
• wherein the controller sums up the starting acceleration entry frequency and an entry time based on the opening of the APS and the engine rpm on a period of the unit time when the air conditioner is operated and recognizes the driving pattern,
• wherein the controller calculates each of a first level change amount according to the starting acceleration entry frequency and a second level change amount according to the starting acceleration entry time for the unit time based on a starting acceleration entry condition of a set level by utilizing a third map which determines a change amount between the levels in the first map,
• and
• wherein the controller determines a smaller change value between the first level change amount according to the entry frequency and the second level change amount according to the entry time as a final change amount and determines a change level based on a driving pattern.
