ABSTRACT:
Temperatures in a first air-conditioning zone and in a second air-conditioning zone are controlled highly independently of each other irrespective of a difference between the setpoint temperatures in these air-conditioning zones or the state of the external air temperature. An ECU 23 calculates target blow-out temperatures in an air-conditioning system 7 on the driver's seat side and in an air-conditioning system 8 on the driver's seat side based upon temperatures Tset(Dr) and Tset(Pa) set by temperature setters 25 and 26, a difference between the setpoint temperatures Tset(Dr) and Tset(Pa), an internal air temperature Tr, an external air temperature Tam, and the amount of solar radiation Ts, and controls, based on the calculated result, the opening degrees of the air-mixing dampers 9, 10 (temperatures of the blown-out airs), blow-out port modes in the air-conditioning systems 7 and 8, and the air blow rate of the blower 3. The ECU 23 corrects the calculation term corresponding to the difference between the setpoint temperatures Tset(Dr) and Tset(Pa) in the air-conditioning zones on the driver's seat side and on the side of the seat next to the driver depending upon the data of external air temperature Tam detected by an external air temperature sensor at the time of calculating the target blow-out temperatures.
