본 발명은 차량용 공조장치에 관한 것으로서, 탑승객이 사이드 벤트그릴을 닫아서 폐쇄시키더라도 차실내 토출공기온도를 정확하게 인식할 수 있고, 이를 통해, 사이드 벤트그릴의 닫침으로 인한 토출공기온도의 "인식오류"와, 그로 인한 "작동오류 현상"을 원천적으로 방지할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 차실내 토출공기온도를 감지할 수 있도록 적어도 2개 이상의 공기토출 벤트그릴 내측에 각각 설치되는 복수의 토출공기온센서들과, 토출공기온센서들로부터 입력된 토출공기온도에 따라 템프도어의 개도위치를 가변 제어하는 제어부를 포함하는 차량용 공조장치에 있어서, 토출공기온센서가 설치된 공기토출 벤트그릴들 중 특정의 공기토출 벤트그릴이 닫혀질 시에, 특정 공기토출 벤트그릴의 닫침을 감지하는 벤트그릴 닫침감지수단을 포함하며, 제어부는, 벤트그릴 닫침감지수단에서 특정 공기토출 벤트그릴이 닫힌 것으로 감지될 시에, 벤트그릴 닫침보상모드로 진입하면서 닫혀진 특정 공기토출 벤트그릴측 토출공기온센서로부터 입력된 토출공기온도는 배제하고, 닫쳐지지 않은 다른 공기토출 벤트그릴측 토출공기온센서로부터 입력된 토출공기온도를 기준으로 템프도어를 제어한다.

    The present invention relates to an air conditioning device for a vehicle. The pair conditioning device is capable of accurately recognizing an indoor discharge air temperature even when a vehicle is sealed as a passenger closes a side vent grill, thereby fundamentally preventing a ″recognition error″ of a discharge air temperature due to the closing of the side vent grill and a ″malfunction error″ caused thereby. To achieve this purpose, the air conditioning device for a vehicle comprises: a plurality of discharge air temperature sensors respectively installed inside at least two air discharge vent grills to detect an indoor discharge air temperature; a control unit for variably controlling the opening position of a temp door according to the discharge air temperature inputted from the discharge air temperature sensors; and a vent grill closing sensing means for sensing the closing of a specific air discharge vent grill when the specific air discharge vent grill is closed from among the air discharge vent grills in which the discharge air temperature sensors are installed. The control unit controls the temp door on the basis of the discharge air temperature inputted from a discharge air temperature sensor of the unclosed air discharge vent grill side, excluding the discharge air temperature inputted from the discharge air temperature sensor of the specific air discharge vent grill which is closed while entering a vent grill close compensation mode when the specific air discharge vent grill is detected to be closed in a vent grill close detection means.
