Abstract

Un dispositif d’estimation (DE) équipe un véhicule (VT) comprenant un habitacle (H) ayant un volume prédéfini et alimenté en air traité par une installation de chauffage et/ou climatisation (IC) comprenant un filtre à air (FA) recevant, selon un débit en cours, des proportions d’air extérieur et d’air recirculé issu de l’habitacle (H) définies par un taux de recirculation. Ce dispositif (DE) comprend un processeur et une mémoire estimant un taux de colmatage du filtre à air (FA) pour au moins un polluant en fonction d’un premier paramètre représentatif d’une efficacité de filtration du polluant par le filtre à air (FA), d’une première concentration du polluant à l’intérieur de l’habitacle (H), d’une seconde concentration du polluant à l’extérieur de l’habitacle (H), et du taux de recirculation.
