CA 2224021

A method and apparatus are provided for generating a route from a source location to a destination in a vehicle navigation system. Initially, the system generates a first partial route from the source location to the end of the first partial route. The system then determines whether a second maneuver is within a first distance from a first maneuver at the end of the first partial route. Where the second maneuver is within the first distance, the system increases the cost associated with the second maneuver. The system then generates a second partial route from the end of the first partial route to the destination, generation of the second partial route being based at least in part on the cost associated with the second maneuver.

Méthode et appareil servant à préparer un itinéraire à partir d'un point de départ et d'un point d'arrivée dans un système de navigation de véhicule. Le système produit d'abord un premier itinéraire partiel du point de départ jusqu'au point d'arrivée du premier itinéraire partiel. Le système détermine ensuite si une seconde manoeuvre est comprise à l'intérieur d'une première distance d'une première manoeuvre à la fin du premier itinéraire partiel. Si la seconde manoeuvre est comprise à l'intérieur de la première distance, le système augmente le coût associé à la seconde manoeuvre. Le système produit ensuite un second itinéraire partiel à partir du point d'arrivée du premier itinéraire partiel jusqu'à la destination; la préparation d'un second itinéraire partiel est fondée au moins en partie sur le coût associé à la seconde manoeuvre.
