CA 2691878

Systems and methods of locating a vehicle are disclosed. A beacon device is placed in the vehicle, the beacon device being capable of wireless signal communication according to preset parameters. The presence of the beacon device is detected on a removable locator device via the wireless signal. Locating technology in the locator device is automatically initiated to establish current location coordinates for the locator device upon detecting the presence of the beacon device. The current location coordinates of the locator device are updated at regular intervals for as long as the locator device remains within signal range of the beacon device. The last updated location coordinates are automatically stored as a waypoint on the locator device upon the locator device ceasing to detect the presence of the beacon device. The stored waypoint represents the approximate location of the vehicle.

L'invention comprend un procédé de localisation d'un véhicule consistant à : a) connecter un dispositif localisateur amovible au véhicule, ledit dispositif localisateur notant automatiquement l'instant où il a été connecté au véhicule puis utilisant la technologie de localisation afin de récupérer, à des intervalles réguliers, les coordonnées de localisation pour l'emplacement actuel dudit dispositif localisateur, lesdites coordonnées de localisation approchant l'emplacement du véhicule; b) détecter une perte de connexion entre le dispositif localisateur et le véhicule; c) mémoriser automatiquement, en tant que point de cheminement sur le dispositif localisateur, les dernières coordonnées de localisation récupérées avant la détection de ladite perte de connexion et; d) retirer le dispositif localisateur du véhicule pour permettre au dispositif localisateur de revenir au point de cheminement mémorisé, le point de cheminement mémorisé représentant l'emplacement approché du véhicule.
