Claim One:
1. In an air-conditioner for use in a vehicle which is equipped with a control unit which receives a detected or estimated value pertaining to a heating value supplied from the air-conditioner to the inside of the vehicle and detected or estimated values pertaining to environmental factors which affect the heating value of the inside of the vehicle other than those of the air-conditioner as inputs and estimates an inside temperature using a heat balance calculation model which uses these detected or estimated values as parameters and with a detection sensor for detecting a temperature of the inside of the vehicle and which constitutes an observer by multiplying the difference between a detected value from the detection sensor and an estimated value obtained from the calculation model by a predetermined gain and by feeding back the obtained value, an air-conditioning control method for a vehicle characterized in that a correction term is created based on the feed-back value to correct the detected value or estimated value used as a parameter.
