Abstract

Procédé d'optimisation simultanée de l'émission d'oxydes d'azote et de dioxyde de carbone d'un moteur à combustion interne équipé d'un système de post-traitement des gaz d'échappement d'un véhicule automobile. Le procédé consiste, au début, à sélectionner (100) un horizon prévisionnel (PH), puis à fixer un seuil d'oxydes d'azote (mnox_act) (101). On minimise (102) une fonction de coût (K) qui comprend l'émission d'oxydes d'azote et l'émission de dioxyde de carbone en respectant le seuil de dioxydes d'azote (mnox_act). Ensuite, on règle le moteur à combustion interne sur une valeur de consigne (S) obtenue en minimisant (102) la fonction de coût (K). On répète les étapes du procédé.
