Abstract

La présente invention a pour objet des modèles d'apprentissage automatique entrainés (300), des procédés (200, 400) et des appareils (500) permettant de prédire une fréquence de résonance future d'un catalyseur de réduction sélective des oxydes d'azote (SCR), la fréquence de résonance étant représentative d'une concentration d'un agent réducteur à l'intérieur du SCR. Le SCR fait partie d'un système de post-traitement d'un écoulement de gaz d'échappement d'un moteur à combustion interne dont est pourvu un véhicule automobile. Le principe général de l'invention est basé sur l'observation de corrélations entre la fréquence de résonance d'un SCR la concentration d'ammoniac présente à l'intérieur du SCR. Cette observation a conduit l'inventeur à envisager l'utilisation de l'apprentissage automatique (« machine learning », en langue anglaise) pour créer un modèle d'apprentissage automatique entrainé afin de prédire la fréquence de résonance d'un SCR. Dans l'invention, le modèle d'apprentissage automatique entrainé est un modèle dit prédictif dans lequel on découvre des corrélations significatives dans un jeu d'observations passées et dans lequel on cherche à généraliser ces corrélations à des cas non encore observés.
