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.

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.
