Abstract

Translated fromFrench

Méthode de mesure de paramètres de fonctionnement d'un moteur (10) de véhicule, la méthode comprenant les étapes consistant à : - mesurer des paramètres moteur au cours du fonctionnement du moteur (10), - enregistrer ou traiter au moins un des paramètres mesurés, caractérisée : en ce que la méthode comprend une étape consistant à évaluer un degré de variabilité d'au moins un des paramètres mesurés, avec les étapes consistant à : - calculer un gradient instantané entre deux mesures successives, - évaluer une variation du gradient instantané, et en ce que la mesure ou le traitement n'est validé que si la variation du gradient instantané dudit au moins un paramètre dont la variabilité a été évaluée est inférieure à un seuil de variabilité prédéterminé.A method of measuring operating parameters of a vehicle engine (10), the method comprising the steps of: - measuring engine parameters during the operation of the engine (10), - recording or processing at least one of the measured parameters , characterized: in that the method comprises a step consisting in evaluating a degree of variability of at least one of the measured parameters, with the steps consisting in: - calculating an instantaneous gradient between two successive measurements, - evaluating a variation of the instantaneous gradient , and in that the measurement or the processing is validated only if the variation of the instantaneous gradient of said at least one parameter whose variability has been evaluated is less than a predetermined variability threshold.
