Abstract

L'invention concerne un procédé permettant de déterminer les moments où il faut changer l'huile moteur ou en ajouter, pour un moteur de véhicule, en fonction de paramètres de fonctionnement du moteur détectés. Selon l'invention, au moins un paramètre de fonctionnement du moteur ayant un lien avec le vieillissement de l'huile moteur et le nombre de tours du moteur sont détectés, et à partir des valeurs obtenues, une distance fictive est établie par combinaison évaluative du nombre de tours du moteur détecté et des facteurs d'évaluation dépendant du ou des paramètres de fonctionnement du moteur détecté ayant un lien avec le vieillissement de l'huile moteur, selon un rapport de combinaison pouvant être prédéfini. A partir de cette distance fictive, la distance pouvant encore être parcourue jusqu'au prochain moment où il faudra changer l'huile ou en ajouter est calculée, la distance fictive déterminée étant, à cet effet, soustraite d'une distance totale possible prédéfinie.
