A vehicle air conditioning system is capable of learning preferences for a plurality of passengers, altering control characteristics of air conditioning means based on the results of learning, and automatically controlling the system. The system is capable of adjusting a temperature separately and independently for the left and right sides of a passenger compartment, and stores a temperature setting map of preferences of respective passengers for the Dr side and Pa side. Temperature set points are used for calculating blowing temperatures and determining opening degrees of air mix dampers. If a set point temperature is changed by a manual setting, the temperature-setting map is altered and restored by learning such change, and thus the temperature-setting map can be updated to reflect preferences of each passenger for each of the Dr side and Pa side.
