Abstract

In a vehicle air conditioner, a front air conditioning unit and a seat air conditioning unit are automatically controlled by an air conditioner ECU. If a seat air conditioner switch is operated by a user during an automatic control, the setting (e.g. air volume of a seat blower) of the seat air conditioning switch is learned. Based on the learning, a seat blower characteristic diagram, which is stored in a ROM, is changed. Therefore, from this time onward, under the same environmental condition, the seat blower air volume is determined based on the changed seat blower characteristic diagram. Accordingly, a seat air conditioning is provided as desired.
