For example, as illustrated in FIG. 25, it is assumed that there are paths connecting points A, B, C, D, and E, and that the user's trajectories of input drag inputs are equal to 1, 2, and 3 respectively. At this time, the path matching drag trajectory 1 becomes ABCE, the path matching drag trajectory 2 becomes BCD, and the path matching drag trajectory 3 becomes ABFCD.

  • the user terminal device 20 displays a map of the enlarged scale as a rescan section so that the user can select and select two or more selectable routes (S2211), and displays the displayed rescan section. Steps S2203 to S2209 are performed again.
  • the above-described process may be performed until there are no two or more selectable paths on the searched paths.

Abstract

La présente invention concerne un procédé de fourniture d'informations, ainsi qu'un dispositif et un système associés et, plus particulièrement un procédé de guidage de déplacement permettant d'ajuster une heure d'arrivée prévue pour un trajet de déplacement et de fournir à un conducteur des informations sur l'heure d'arrivée prévue, au moyen d'informations de surface de roulement en provenance d'une pluralité d'autres véhicules, lors de la conduite d'un véhicule, ainsi qu'un dispositif et un système associés. Les informations de surface de roulement sur un trajet défini, qui changent en temps réel, sont obtenues en provenance de plusieurs appareils tels qu'un ABS, un capteur de pluie et analogues prévus dans un véhicule. Le fait que l'état d'une surface de route soit différent d'un état de surface de roulement normal est déterminé sur la base des informations de surface de roulement obtenues et, si l'état de la surface de roulement est dangereux et nécessite l'attention d'un conducteur, les informations sur l'état de surface de roulement sont fournies aux conducteurs de véhicules devant passer dans la zone correspondante, ce qui permet aux conducteurs de véhicules de planifier aisément un trajet de déplacement.
