ABSTRACT:
To enable performance of comfortable rear seat air temperature control when an air temperature control system is changed from a state where solely a front seat air temperature control unit is operating to a state where a rear seat air temperature control unit also is operating, when deviation between temperature Tr(Fr) detected by a front seat inner air temperature sensor and a temperature Tr(Rr) detected by a rear seat inner air temperature sensor is a predetermined temperature A or more, a temperature Tr'(Rr) used in calculating a rear seat target blowing temperature is taken to be Tr(Fr)--B'. Additionally, when the above-mentioned deviation is A or less, Tr'(Rr) is taken to be equal to Tr(Rr). Due to this, Tr'(Rr) gradually rises and moreover, this Tr'(Rr) is a temperature more closely approaching a rear seat mean temperature, and so by controlling a rear seat air temperature control unit based on the rear seat target blowing temperature calculated based on this Tr'(Rr), problems such as variations in air quantity and hunting of a vent mode can be prevented, and comfortable rear seat air temperature control can be performed.
