An on-board automobile navigation system provides route guidance instructions to a user. The system detects a power-down of the vehicle and, in response, determines whether to resume route guidance in response to the next start-up of the vehicle. This determination is made prior to powering down the system. The determination is based on the current position of the vehicle and the computed route. If a determination was made to resume guidance after start-up, the selected destination and the computed route are saved in memory before powering down the system. If a determination was made to resume guidance, then in response to the next start-up of the vehicle, the selected destination and the computed route of the vehicle are recalled from memory, and route guidance is resumed from the current position of the vehicle.
Cette invention concerne un système de navigation embarqué servant à guider le conducteur d'une automobile. Le système détecte les arrêts du véhicule et détermine immédiatement s'il faut réactiver la fonction de guidage au prochain démarrage du véhicule. Cette détermination est faite avant la mise hors tension du système. La décision est basée sur la position du véhicule par rapport à la destination entrée. Si la décision est de reprendre la fonction de guidage au prochain démarrage, la destination choisie et l'itinéraire correspondant sont sauvegardés en mémoire avant la mise hors tension du système et rappelés au prochain démarrage pour reprendre le guidage à partir de la position actuelle du véhicule.
