Abstract
(DE)
Verfahren zum Überwachen eines Energiespeichers in einem Bordnetz eines Kraftfahrzeugs, bei dem mindestens eine aktuelle Betriebsgröße des Energiespeichers bestimmt wird und diese mindestens eine Betriebsgröße an ein Prognosemodell weitergegeben wird und dieses Prognosemodell aus dem aktuellen Wert für die mindestens eine Betriebsgröße zukünftige Werte für die mindestens eine Betriebsgröße bestimmt, wobei der zukünftige Wert der mindestens einen Betriebsgröße an einen Spannungsprädiktor gegeben wird, der eine zu erwartende Minimalspannung des Energiespeichers für eine ausgewählte Funktion berechnet.
(EN)
The invention relates to a method for monitoring an energy storage device in a vehicle electrical system of a motor vehicle, in which method at least one current operating variable of the energy storage device is determined and said at least one operating variable is forwarded to a forecast model and said forecast model determines future values for the at least one operating variable from the current value for the at least one operating variable, wherein the future value of the at least one operating variable is provided to a voltage predictor which calculates an expected minimum voltage of the energy storage device for a selected function.
(FR)
L’invention concerne un procédé permettant de de surveiller un accumulateur d’énergie dans un réseau de bord, procédé selon lequel au moins un paramètre de fonctionnement actuel de l’accumulateur d’énergie est déterminé et transmis à un modèle de prédiction qui détermine, à partir de la valeur actuelle dudit au moins un paramètre de fonctionnement, des valeurs futures dudit au moins paramètre de fonctionnement. La valeur future dudit au moins un paramètre de fonctionnement est transmise à une unité de prédiction de tension qui calcule une tension minimale prévue de l’accumulateur d’énergie pour une fonction sélectionnée.
