PROBLEM TO BE SOLVED: To provide a vehicular ventilation device for properly controlling a ventilation amount in a passenger compartment even in a state in which an operation of a vehicle is intermittent.SOLUTION: A vehicular ventilation device performs: processing of a step S4 (carbon dioxide density estimation means) for calculating an estimated value of CO2 density in a passenger compartment according to an operation state of a vehicle; processing of steps S5-S10 (ventilation amount control means) for controlling a ventilation amount in the passenger compartment according to the estimated CO2 density; and steps S12, S1-S3 for determining an initial value of the CO2 density in the passenger compartment according to at least the CO2 density recorded in an operation stop and an operation stop period which is detected in an operation start.SELECTED DRAWING: Figure 3
【課題】車両の運転が断続される状態においても、車室の換気量を的確に制御する車両用換気装置を提供すること。【解決手段】車両用換気装置は、車両の運転状態に応じて車室におけるCO2濃度の推定値を計算するステップS4の処理(二酸化炭素濃度推定手段)と、推定されたCO2濃度に応じて車室の換気量を制御するステップS5〜S10の処理(換気量制御手段)と、少なくとも運転停止時に記録されたCO2濃度と、運転開始時に検知された運転停止時間と、に応じて車室のCO2濃度の初期値が求めるステップS12、S1〜S3の処理(初期値計算手段)と、を行う構成とした。【選択図】図3
