Abstract

Procédé et dispositif d’analyse d’un réseau électrique embarqué dans un véhicule La présente invention concerne un procédé d’analyse d’un réseau électrique (30) embarqué dans un véhicule, le réseau électrique (30) comportant des organes électroniques de coupure (32, 34, 36) de différents calibres, le procédé d’analyse étant caractérisé en ce qu’il comporte :- une étape de mesure d’un courant (I) traversant un des organes électroniques de coupure (32,34,36) lorsque l’organe électronique de coupure (32,34,36) est dans un état passant, sur une période d’analyse (p), et- une étape de détermination d’un surdimensionnement, d’un sous-dimensionnement ou d’un bon dimensionnement de l’organe électronique de coupure (32,34,36) par rapport à une utilisation de l’organe électronique de coupure (32,34,36) sur la période d’analyse (p), à partir d’un calibre de l’organe électronique de coupure (32,34,36) et d’au moins une mesure de courant issue de l’étape de mesure. (Figure 1)Method and device for analyzing an electrical network on board a vehicle The present invention relates to a method for analyzing an electrical network (30) on board a vehicle, the electrical network (30) comprising electronic cut-off members (32, 34, 36) of different ratings, the analysis method being characterized in that it comprises: - a step of measuring a current (I) flowing through one of the electronic cut-off members (32, 34, 36) when the electronic cut-off member (32, 34, 36) is in a conducting state, over an analysis period (p), and - a step of determining an oversizing, an undersizing or a good sizing of the electronic cut-off member (32, 34, 36) with respect to a use of the electronic cut-off member (32, 34, 36) over the analysis period (p), from a rating of the electronic cut-off member (32, 34, 36) and of at least one current measurement from the measurement step.
