PROBLEM TO BE SOLVED: To provide a contamination degree estimation device capable of accurately estimating a contamination degree of an air cleaner while suppressing increase in the cost.SOLUTION: A contamination degree estimation device 400 includes: an information acquiring unit 402 for acquiring information showing a traveling state of a vehicle for each of prescribed traveling sections; a coefficient determination unit 404 for determining a contamination coefficient K on the basis of the traveling state shown by the information for each of the traveling sections; and a contamination degree calculating unit 412 for calculating an increment of a contamination degree on the basis of a multiplication value of the contamination coefficient K and a distance of the traveling section for each of the traveling sections, and calculating an integrated value of the increment which is calculated for each of the traveling sections as the contamination degree.SELECTED DRAWING: Figure 2

    【課題】コストの増大を抑制しつつ、エアクリーナの汚損度を精度良く推定することができる汚損度推定装置を提供する。【解決手段】汚損度推定装置400は、所定の走行区間ごとに、車両の走行状況を示す情報を取得する情報取得部402と、走行区間ごとに、情報によって示される走行状況に基づいて汚損係数Kを決定する係数決定部404と、走行区間ごとに、汚損係数Kと当該走行区間の距離との乗算値に基づいて汚損度の増加分を算出し、走行区間ごとに算出された増加分の積算値を汚損度として算出する汚損度算出部412とを備える。【選択図】図2
