Abstract

Le dispositif d'affichage de carte (100) selon l'invention comporte une section d'affichage (101) pour afficher des informations cartographiques, une section de détection de direction (102) pour détecter la direction de mouvement, une section de détection de vitesse (103) pour détecter la vitesse d'un corps mobile, une section de détermination (104) pour déterminer si oui ou non le corps mobile se déplace sur une route comportant une courbe, et un dispositif de commande d'affichage (107) pour commander la section d'affichage (101). Selon le résultat de la détection et de la détermination par la section de détection de direction (102), la section de détection de vitesse (103) et la section de détermination (104), la section de commande d'affichage (107) change la position d'un repère affiché sur un écran d'affichage et représentant la position courante du corps mobile. Le changement est effectué de sorte que la région devant la direction de mouvement du corps mobile ou la région en direction d'une courbe soit plus grande que la région derrière la direction de mouvement du corps mobile ou que la région en direction d'une courbe soit plus grande que la région opposée à la direction de la courbe. Après le changement, la section de commande d'affichage (107) affiche des informations cartographiques, dans lesquelles la position d'affichage du repère est changée, sur la section d'affichage (101). Ceci permet que les informations cartographiques sur une zone supplémentaire puissent être confirmées.
