To provide a vehicle interior air quality maintenance device capable of favorably ventilating CO2 in a vehicle interior while preventing polluted external air from flowing into the vehicle interior on the basis of information on inside and outside of the vehicle interior.SOLUTION: A vehicle interior air quality maintenance device comprises: a vehicle interior and exterior air switching section 120 which forms a portion of an air-conditioning device and can switch between an exterior air mode to introduce external air into a vehicle interior and an interior air mode to circulate air inside the vehicle interior; and a control section 150 which performs switching control causing the vehicle interior and exterior air switching section to be switched to the interior air mode when a pollution state of the external air is higher than a predetermined value. After switching to the interior air mode, the control section controls a timing to switch from the interior air mode to the exterior air mode in accordance with an interior air prediction map showing predicted time X until a CO2 concentration in the vehicle interior becomes equal to or higher than a predetermined threshold and an external air map showing the pollution state of the external air.SELECTED DRAWING: Figure 1

    【課題】車室内外の情報をもとに、汚染された外気の侵入を抑制しつつ、車室内のCO2の好適な換気を実施可能とする車室内空気質維持装置を提供する。【解決手段】空調装置の一部を成し、車両の室内に外気を取入れる外気モードと室内の空気を循環させる内気モードとを切替え可能な内外気切替え部120と、外気の汚染状態が所定値よりも高いときに、内外気切替え部を内気モードに切替え制御する制御部150と、を備える車室内空気質維持装置であって、制御部は、内気モードに切替えた後に、室内のCO2の濃度が予め定めた閾値以上となるまでの予測時間Xを示す内気予測マップと、外気の汚染状態を示す外気マップとに応じて、内気モードから外気モードへの切替えタイミングを制御する。【選択図】図1
