In this case, the vehicle is traveling at a relatively high speed, and if the logo mark is displayed near the road on which the vehicle is traveling, the road becomes difficult to see.

This is because if the logo marks are not dense, it is unlikely that the road will be difficult to see even if they are displayed.
  • Whether or not logo marks are dense can be determined based on, for example, the range of logo marks extracted in step S20, that is, the number and density of logo marks in a predetermined range from the current position. .

Abstract

L'invention concerne une marque de logo nécessaire pouvant être affichée dans un dispositif de navigation à bord d'un véhicule selon une condition de circulation du véhicule de sorte qu'un utilisateur peut facilement voir la marque de logo. Le dispositif de navigation affiche une carte d'une zone d'affichage comprenant la position actuelle du véhicule sur un dispositif d'affichage et affiche une marque de logo d'une installation existant dans la zone d'affichage. L'affichage de marque de logo est commandé selon la condition de circulation du véhicule. Par exemple, le type des marques de logo à afficher est décidé selon la fréquence d'utilisation de l'installation, le type de la route où le véhicule circule, la vitesse de circulation du véhicule et similaires. En conséquence, il est possible d'afficher une marque de logo appropriée selon la condition de circulation du véhicule de sorte que l'utilisateur peut facilement voir la marque de logo.
