AIR-CONDITIONING CONTROL SYSTEM

PROBLEM TO BE SOLVED: To enhance the possibility of obtaining vehicle interior absolute humidity with high calculation accuracy.SOLUTION: An air-conditioning control system 1 includes: an air conditioner 10; a vehicle exterior humidity information acquisition section 44 for acquiring vehicle exterior humidity information that indicates humidity of outside air at a position of a vehicle and indicates the humidity when a start switch 5 of the vehicle is turned on; an outside air introduction processing section 46 for executing outside air introduction processing for making an outside air introduction percentage of the air conditioner larger than 0% in an off state of the start switch 5; and a humidity calculation section 48 for calculating vehicle interior absolute humidity of the vehicle by using the absolute humidity on the basis of the vehicle exterior humidity information acquired by the vehicle exterior humidity information acquisition section 44 as an initial value, when a first condition indicating that the outside air introduction processing has been executed by the outside air introduction processing section is satisfied.SELECTED DRAWING: Figure 1 【課題】算出精度の高い車内絶対湿度が得られる可能性を高めること。【解決手段】空調制御システム１は、空調装置１０と、前記車両の位置における外気の湿度を表す車外湿度情報であって、前記車両の起動スイッチ５がオンされたときの前記湿度を表す車外湿度情報を取得する車外湿度情報取得部４４と、前記起動スイッチ５のオフ状態において前記空調装置の外気導入率を０％よりも大きくする外気導入処理を実行する外気導入処理部４６と、前記外気導入処理部により前記外気導入処理が実行されたことである第１条件が満たされた場合に、前記車外湿度情報取得部４４により取得された前記車外湿度情報に基づく絶対湿度を初期値として、前記車両の車内絶対湿度を算出する湿度算出部４８とを含む。【選択図】図１
