A vehicular HVAC system includes a casing allowing air to flow from outdoors into the interior of a passenger compartment, an air blower blowing the air into the casing, an evaporator disposed in the casing, a heater core disposed downstream of the evaporator, and front and rear seat side temperature doors disposed between the evaporator and the heater core. A method for controlling the vehicular HVAC system includes the steps of: determining whether a required temperature for cooling rear seats is set to be lower than a required temperature for cooling front seats after an outdoor condition of a vehicle meets a reference high temperature condition; and lowering, by a controller, a target temperature of the evaporator based on the set required temperature for cooling the rear seats when the required temperature for cooling the rear seats is set to be lower than the required temperature for cooling the front seats. The present invention can improve passenger convenience by independently controlling the cooling operation for the rear seat.

    개시된 차량용 HVAC시스템은 승객실 외부로부터 승객실의 내부로 공기가 흐름을 허용하는 케이싱과, 상기 케이싱 내로 공기를 불어주는 에어블로워와, 상기 케이싱 내에 배치된 증발기와, 증발기의 하류 측에 배치된 히터코어와, 증발기 및 히터코어 사이에 배치된 전석 템프도어 및 후석 템프도어를 포함한다. 차량용 HVAC시스템의 제어방법에 의하면, 차량의 외부조건이 기준 고온조건에 도달한 이후에 후석측 냉방요구온도가 전석측 냉방요구온도 보다 낮게 설정되었는지를 판단하고, 제어기에 의해 상기 후석측 냉방요구온도가 상기 전석측 냉방요구온도 보다 낮게 설정되면 상기 설정된 후석측 냉방요구온도에 기초하여 상기 증발기의 타겟온도를 상대적으로 낮게 설정할 수 있다.
