To effectively suppress a window from being fogged while enhancing consumption efficiency of electric power.SOLUTION: A defogging system X, which is for a vehicle 1 provided with a photographing device 10 that photographs a space outside the vehicle through a window from a space in the vehicle, comprises: first detecting devices 41 and 42 that detect a state of the space in the vehicle; an obtaining device 61 that obtains vital data on an occupant; defoggers 19 and 20 that suppress the window from being fogged; and a control device 26 that controls the defoggers 19 and 20. The control device 26 estimates an initial water vapor amounts which are water vapor amounts in the space in the vehicle at a current time, on the basis of the results detected by the first detecting devices 41 and 42; estimates discharged water vapor amounts which are water vapor amounts discharged per unit time by the occupant, on the basis of the result obtained by the obtaining device 61; and predicts future fogging of the window on the basis of the estimated values of the initial water vapor amounts and estimated values of the discharged water vapor amounts, and controls the defoggers 19 and 20 on the basis of the result of prediction.SELECTED DRAWING: Figure 3
【課題】電力の消費効率を高めつつ、窓の曇りを効果的に抑制する。【解決手段】車内空間から窓を介して車外空間を撮影する撮影装置10を備えた車両1のための曇り止めシステムXであって、車内空間の状態を検出する第1検出装置41、42と、乗員のバイタルデータを取得する取得装置61と、窓の曇りを抑制する曇り止め装置19、20と、曇り止め装置19、20を制御する制御装置26と、を備え、制御装置26は、第1検出装置41、42の検出結果に基づいて現在時刻における車内空間の水蒸気量である初期水蒸気量を推定し、取得装置61の取得結果に基づいて乗員が単位時間当たりに放出する水蒸気量である放出水蒸気量を推定し、初期水蒸気量の推定値と放出水蒸気量の推定値とに基づいて窓の将来の曇りを予測し、その予測結果に基づいて曇り止め装置19、20を制御する。【選択図】 図3
