Abstract

L'invention porte sur un procédé de surveillance d'un système de motorisation d'un véhicule, comprenant : - une étape d'enregistrement de la valeur d'un ensemble de paramètres prédéterminé dans la mémoire volatile de l'unité de contrôle électronique, - lors de la survenance d'une anomalie à un instant, une étape de détermination d'une séquence d'enregistrement de la valeur de l'ensemble de paramètres sur une période de temps précédant l'instant de survenance de l'anomalie, ladite période comprenant trois sous-périodes : ○ durant une première sous-période, ladite séquence présente un premier pas d'échantillonnage, ○ durant une deuxième sous-période, ladite séquence d'enregistrement présente un deuxième pas d'échantillonnage, supérieur au premier, ○ durant une troisième sous-période, ladite séquence d'enregistrement présente un troisième pas d'échantillonnage, supérieur au deuxième, - une étape de stockage dans la mémoire volatile de ladite séquence d'enregistrement.The invention relates to a method for monitoring a motorization system of a vehicle, comprising: a step of recording the value of a set of predetermined parameters in the volatile memory of the electronic control unit, - upon the occurrence of an anomaly at a given instant, a step of determining a sequence for recording the value of the set of parameters over a period of time preceding the instant of occurrence of the anomaly, said period comprising three sub-periods: ○ during a first sub-period, said sequence has a first sampling step, ○ during a second sub-period, said recording sequence has a second sampling step, greater than the first, ○ during a third sub-period, said recording sequence has a third sampling step, greater than the second, - a step of storing in the volatile memory of said recording sequence.
