Abstract

Procédé de correction de commande d'un moteur thermique (10) comprenant un dispositif d'injection (15) utilisant une valeur de consigne de richesse (R) comprenant : • une première phase de commande du moteur (10), appliquée dans un premier domaine (D1) de fonctionnement dudit moteur, incluant une étape de correction directe de richesse consistant à corriger la consigne de richesse (R), utilisée par le dispositif d'injection (15), au moyen d’au moins un adaptatif direct qui identifie et mémorise les écarts entre la consigne et la consigne de richesse et une mesure (M) de richesse obtenue par une unité de mesure (32), • une deuxième phase de commande du moteur thermique (10), appliquée dans un deuxième domaine (D2) de fonctionnement dudit moteur, incluant : - l’identification d'une dérive de fonctionnement d'un actionneur du moteur, - l'établissement d’au moins un adaptatif indirect applicable à une loi de pilotage dudit actionneur, et - une étape de correction indirecte de richesse consistant à piloter ledit actionneur (15’), par ledit adaptatif indirect, caractérisé en ce que ledit procédé mémorise ledit adaptatif indirect après avoir été établi et met en œuvre ladite étape de correction indirecte de richesse dans la première phase de commande du moteur thermique (10) lorsque ledit moteur thermique (10) se retrouve dans ledit premier domaine (D1) de fonctionnement.
