PURPOSE: A performance compensating automatic air conditioning control algorithm for vehicles is provided to maintain the air conditioning control ability constant regardless of change in air conditioning environment and performance deterioration of automatic temperature controller. CONSTITUTION: A control algorithm comprises a step(S201,S202) of setting the target temperature for indoor area of the vehicle, and inputting outdoor environmental conditions including the current indoor temperature, outdoor air conditioning load and set temperature to the control algorithm; a step(203) of calculating an optimum indoor temperature in accordance with the difference between the target temperature and the initial indoor temperature of the vehicle and inputting the optimum indoor temperature to the control algorithm; a step(S204) of adjusting the degree of opening of a blend door actuator and the blow amount of an evaporator in accordance with the control algorithm; a step(S205) of allowing the mixture of the cold air by-passed by the opening of the blend door actuator and the hot air passed through a heater to be supplied to the indoor area of the vehicle, and detecting the indoor temperature; and a step(S206-S208) of comparing the detected indoor temperature with the optimum indoor temperature, and compensating the control algorithm by changing the offset value when the difference is higher than a reference level.
