PROBLEM TO BE SOLVED: To provide a method of controlling a variable capacity compressor of a vehicle air conditioner for improving convergence of evaporator temperature and responsiveness. SOLUTION: The method comprises the steps of: setting a target indoor temperature by a user; sensing and inputting car indoor temperature, car outdoor temperature and solar radiation using sensors; calculating a target discharge temperature of a vent using these; calculating a target evaporator temperature and blower voltage according to the target discharge temperature; calculating a control duty according to the target evaporator temperature; calculating a target evaporator temperature change rate and a blower voltage change rate; determining whether or not it comes under a sudden variable condition; and setting the maximum value of the control duty change rate to an accelerative slew rate (Sc) greater than a basis slew rate (SO) when the sudden variable condition is determined, while setting the maximum value of the control duty change rate to the basic slew rate (SO) when it does not come under the sudden variable condition.
