Abstract
L’invention concerne un procédé, mis en œuvre dans un contrôle moteur d’un véhicule, de surveillance de plusieurs adaptatifs d’au moins un paramètre, le procédé comportant les étapes suivantes : un calcul (10), pour chaque adaptatif, d’une valeur d’impact individuel dudit adaptatif sur ledit au moins un paramètre pour un point de fonctionnement courant du moteur ;un calcul (12) d’une valeur d’impact global de l’ensemble des adaptatifs sur ledit au moins un paramètre pour le point de fonctionnement courant du moteur ;une comparaison (14) de la valeur d’impact global calculée à au moins une valeur seuil d’impact global prédéfinie ; etune émission (16), en fonction du résultat de la comparaison (14), d’un signal d’alerte à destination d’un dispositif du véhicule.
