Title
(EN) VEHICLE RANGE ESTIMATOR
(FR) ESTIMATEUR D'AUTONOMIE DE VÉHICULE
Abstract
(EN)
The present disclosure provides a method for determining the range of an electric vehicle or a hybrid electric vehicle. The method determines the range by estimating a SOC of the vehicle battery and/or a fuel gain by segregating estimation events and weight averaging data samples based on distance traveled during a sample period. The present disclosure also provides a method for determining battery failure for vehicles.
(FR)
La présente invention concerne un procédé de détermination de l'autonomie d'un véhicule électrique ou d'un véhicule électrique hybride. Le procédé détermine l'autonomie par estimation d'un état de charge de la batterie de véhicule et/ou d'un gain de carburant par ségrégation d'événements d'estimation et pondération d'échantillons de données sur la base d'une distance parcourue pendant une période échantillon. La présente invention concerne également un procédé de détermination de défaillance de batterie pour des véhicules.
