  • the goal is that the deviation is compared with the threshold, wherein the deviation within the plausibility range is assessed as a tolerable correction requirement and the deviation outside the plausibility range as a non-tolerable correction requirement.

Abstract

L'invention concerne un procédé et un dispositif permettant d'évaluer l'écart (18) d'au moins une plage d'une courbe caractéristique d'un capteur de gaz d'échappement, disposé dans un conduit d'échappement d'un moteur à combustion interne, par rapport à au moins une valeur de référence. Un procédé robuste de correction de courbe caractéristique permettant une optimisation fiable des polluants est obtenu par le fait qu'aux fins d'évaluation dudit écart (18) au moins une valeur seuil est prédéfinie, laquelle constitue un critère permettant d'établir une distinction entre un besoin de correction tolérable et un besoin de correction non tolérable.
