To inhibit frosting on an outdoor heat exchanger for heating during parking of a vehicle in a vehicular frosting inhibition device.SOLUTION: A vehicular frosting inhibition device 10 includes: a grille shutter 12 disposed at the front side relative to an outdoor heat exchanger used for heating in a passenger compartment; a shutter control unit 21 which controls opening/closing of the grille shutter 12; and a meteorological information acquisition part 18 which acquires meteorological information including time change of a forecasted outdoor temperature in a vehicle current position. The shutter control unit 21 performs frosting forecast, in which whether or not frost is formed on the outdoor heat exchanger by using the forecasted outdoor temperature, when the vehicle is parked, and the frosting forecast forecasts that frost is formed on the outdoor heat exchanger at a time when the forecasted outdoor temperature becomes a predetermined temperature or lower. The shutter control unit 21 closes the grille shutter 12 before the forecasted time of frosting on the outdoor heat exchanger.SELECTED DRAWING: Figure 2
【課題】車両用着霜抑制装置において、車両の駐車中における暖房用の室外熱交換器への着霜を抑制する。【解決手段】車両用着霜抑制装置10は、車室内の暖房に用いられる室外熱交換器より前側に配置されるグリルシャッター12と、グリルシャッター12の開閉を制御するシャッター制御部21と、車両の現在位置における予測外気温度の時間変化を含む気象情報を取得する気象情報取得部18とを含む。シャッター制御部21は、車両の駐車時に、予測外気温度を用いて、室外熱交換器に着霜がされるか否かを予測する着霜予測を行い、着霜予測は、予測外気温度が所定温度以下となる時間に室外熱交換器に着霜がされることを予測する。シャッター制御部21は、室外熱交換器への着霜の予測時間より前にグリルシャッター12を閉じる。【選択図】図2
