Disclosed is an apparatus for displaying a travel position, which, in carrying out steps of calculating X- and Y-coordinates of a current position of the moving body; renewably presenting said current position on a road map indicated on a display screen; matching between a travel trace pattern formed by subsequent current positions and each road pattern on the road map; and putting the travel trace on the mated road pattern for correction of the current position of the moving body deviated from the road on the map, can determine what class of the road the moving body is running on, e.g. mountain road, superhighway or other ordinary road, and also can change the pattern matching condition to be adapted for the class of the road.

La présente invention est un appareil pour afficher une position de déplacement qui, dans l'exécution les étapes du calcul des coordonnées X- et Y- d'une position actuelle du corps en déplacement, présentant constamment ladite position actuelle sur une carte de route indiquée sur un écran d'affichage; associant le tracé de déplacement formé par les positions actuelles subséquentes et chaque itinéraire de route sur une carte de route et mettant l'itinéraire de voyage sur un tracé de route mat pour fins de correction de la position actuelle du corps en déplacement s'il dévie de la route sur la carte, peut déterminer sur quel type de route le corps se déplace, par exemple, route de montagne, autoroute ou autre route ordinaire, et peut aussi changer la condition d'association à l'itinéraire pour l'adapter au type de route.
