Abstract

La présente invention porte sur un procédé de calibration d'une conversion d'un catalyseur de moteur thermique comportant: - une étape (204) de réalisation de mesures physiques de réponses du catalyseur en fonction de paramètres de variation définis par un régime moteur (N), et/ou une charge moteur (T), et/ou une richesse (Rich) de mélange air/carburant, et/ou une amplitude (A_stim) et une fréquence (F_stim) de stimulation du catalyseur, - une étape (205) d'élaboration d'un modèle (M_cat) des réponses du catalyseur et du moteur thermique en fonction des paramètres de variation, et - une étape (206) d'optimisation numérique de la richesse (Rich) de mélange air/carburant, de l’amplitude (A_stim) et de la fréquence (F_stim) de stimulation du catalyseur par minimisation des réponses modélisées sous contraintes, de façon à obtenir des conditions de fonctionnement optimum de fonctionnement du catalyseur.
