  • the display controller 4 calculates the recommended route by the recommended route calculator 5 (step ST1301), and when the current position is detected by the current position detector 2 and the position data is updated (step ST1). 1 3 0 2), Judge whether it is necessary to read out map data from map information storage device 1
  • Step ST1303 When it is necessary to read the map data, for example, the map data including the current position is read from the map information storage device 1 (step ST1304), and the city map drawing data to be displayed on the display device 3 is read. Update (step ST1305). Thereafter, the map of the city including the current position is displayed on the display device 3 (step ST1306), and the recommended route calculated by the recommended route calculation device 5 and the recommended route calculated by the current position detection device 2 are detected. The data of the step offset position corresponding to the number of lanes of the road corresponding to the current position is read out from the map information storage device 1 (step ST 13 07), and the step offset position is recommended as the recommended route and the current position. The route mark and the vehicle mark are displayed on the city map displayed on the display device 3 (step ST 13 08).
  • the recommended route mark and the own vehicle mark are offset from the vector data and displayed at a location that is actually close, so that the user can obtain the current recommended route and the own vehicle mark.
  • the position of the vehicle can be accurately grasped, and the vehicle can travel without erroneous recommended routes.
  • the recommended route mark and the own vehicle mark can be displayed at the current position according to the number of lanes.For example, when the number of right and left lanes is different, the user recognizes that and recommends the recommended route. The effect of being able to judge is obtained.
  • the step offset position in advance in the map information storage device 1 such as a CD-ROM, it is recommended that the offset be quickly set to a position close to the actual position without burdening the display control device 4.
  • the advantage is that the route mark and the own vehicle mark can be displayed.
  • Fig. 16 (a) shows an example of moving the recommended route mark from the left lane to the right lane at a position 50 m before the intersection
  • Fig. 16 (b) Shows an example of moving from the center lane to the left lane at a position 50 m before the intersection.
  • the position of the own vehicle on the map and the recommended route are corrected to the actual position using the width, lane data, and the like, and displayed. Can be reliably performed.

Abstract

La présente invention concerne un système de navigation dans lequel des renseignements cartographiques permettant à une unité de mémoire d'information cartographique d'afficher une carte, des données vectorielles correspondant aux routes sur la carte et des données concernant la largeur des routes sont mémorisées. Lorsqu'un détecteur de la position actuelle détecte une position actuelle, un contrôleur d'affichage lit les renseignements cartographiques correspondant à la position actuelle détectée à partir de l'unité de mémoire d'information cartographique et affiche les renseignements cartographiques sur un dispositif d'affichage, lit les données vectorielles et les données concernant la largeur correspondant à la position actuelle détectée à partir de la mémoire d'information cartographique, calcule une position de déport à partir de la position actuelle sur les données vectorielles en fonction de données concernant la largeur, et affiche la position de déport calculée comme la position actuelle sur la carte affichée sur le dispositif d'affichage.
