Abstract

L’invention concerne un procédé d’initialisation, par une unité de calcul embarqué dans un véhicule, d’une base de donnée cartographique stockée dans une mémoire dédiée, comportant des étapes de :- acquisition (31) d’une position géographique du véhicule,- détermination (32) d’un périmètre, comportant une pluralité de zones élémentaires, à partir de la position acquise,- sélection (33) d’une zone élémentaire appartenant au périmètre,- téléchargement (34) de la zone élémentaire sélectionnée et stockage de la zone élémentaire téléchargée dans la base de donnée cartographiques,- vérification (35) si la mémoire dédiée est pleine,- si la mémoire dédiée n’est pas pleine alors la répétition des étapes de sélection (33) et de téléchargement (34) d’une zone élémentaire jusqu’au remplissage de la mémoire dédiée ou au téléchargement de la totalité des zones appartenant au périmètre. Figure pour l’abrégé : Figure 3The invention relates to a method for initializing, by a calculation unit on board a vehicle, a cartographic database stored in a dedicated memory, comprising steps of:- acquisition (31) of a geographical position of the vehicle ,- determination (32) of a perimeter, comprising a plurality of elementary zones, from the acquired position,- selection (33) of an elementary zone belonging to the perimeter,- downloading (34) of the selected elementary zone and storage of the elementary zone downloaded in the cartographic database, - verification (35) if the dedicated memory is full, - if the dedicated memory is not full then the repetition of the steps of selection (33) and downloading (34 ) of an elementary zone until the dedicated memory is filled or all the zones belonging to the perimeter are downloaded.
