Abstract

La présente invention concerne des installations de repos possibles dans une zone de recherche prédéfinie comprenant un emplacement indiqué par des informations de position d'un véhicule, les installations possibles étant extraites par l'utilisation d'informations de position du véhicule et d'informations d'installation. Lesdites installations possibles qui satisfont à une condition de recherche définie sur la base des informations de préférence sont recherchées. Le besoin de mettre à jour les installations de repos possibles est déterminé conformément à la distance que le véhicule a parcourue depuis le moment où les informations de position du véhicule ont été détectées. Lorsqu'une mise à jour nécessaire est déterminée, les installations de repos possibles sont à nouveau recherchées et une installation de repos possible récupérée est présentée.
