  • the navigation device 320 verifies the version information of the accessed map data file and the latest version information received in step S801 among the map data recorded in the device itself. As a result of the verification in step S803, the navigation device 320 determines whether or not the map data recorded in the own device is the latest version (step S804). If the map data recorded in the navigation device 320 is the latest version (step S804: Yes), the processing according to this flowchart is terminated because there is no need for updating.
  • access to the map data file is a trigger for purge verification.
  • the version information received in step S801 and the version information of the map data recorded in the device itself You can automatically compare and verify if there is a new V, version of map data.
  • step S804 if the map data recorded in the navigation device 320 is not the latest version (step S804: No), the user is notified that the map data is not the latest version (step S805). Then, it is determined whether or not to update the map data (step S806). The determination as to whether or not to update the map data is made based on, for example, whether or not the user has instructed the update process.
  • step S806: Yes If the map data is to be updated (step S806: Yes), the process proceeds to step S807 in FIG. On the other hand, if the map data is not updated (step S806: No), the processing according to this flowchart is terminated because there is no need for updating.
  • the navigation device 320 displays a map data update menu (step S807).
  • the update of the map data can be performed by designating an area and a category.
  • the update menu displays the areas and categories that can be updated, and the user selects these to select the update location.
  • the area where the map data is to be updated is specified by the name or address of a certain town.
  • data to be updated such as road shape data and facility information is specified. Further, by combining these, for example, it may be possible to specify that the convenience store information in Meguro Ward is updated.
  • Navigation device 320 waits until an update location is selected (step S808:
  • step S808 Yes
  • step S809 the update data of the selected update location is downloaded (step S809).
  • downloaded updates The map data is rewritten using the data (step S810), and the processing according to this flowchart is terminated.
  • a charging process may be performed.
  • the billing process is performed, for example, immediately after rewriting of the map data, or when the map data is rewritten to the latest version and the latest version of map data is accessed for the first time. Also good.
  • the map data can be updated with priority given to the portion including the current location of the vehicle 330 or the location registered as home. As a result, it is possible to preferentially update the map data having a higher importance for the user and to use the updated map data more effectively.
  • the navigation device 320 receives the latest version information distributed from the management server 310, and the version information of the map data recorded in the device itself. Compare with 'Notify. As a result, the user can sequentially know whether or not the map data can be updated, and can update the map data quickly if necessary to keep the map data up-to-date.
  • Updates can be made with the user's consent.
  • map data can be updated at the same time.
  • time and cost required for the update process (communication costs, data usage fees, etc.) can be reduced.
  • the data update method described in the present embodiment can be realized by executing a prepared program on a computer such as a personal computer or a workstation.
  • This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by reading the recording medium force by the computer.
  • Mako This program may be a transmission medium that can be distributed via a network such as the Internet.

Abstract

La présente invention concerne un dispositif de mise à jour de données (100) qui met à jour des données cartographiques de manière partielle, ces données étant utilisées par un corps mobile. Une unité d’enregistrement (101) enregistre des données cartographiques. Une unité de mise à jour (102) met à jour les données cartographiques dans l’unité d’enregistrement (101). Une unité d’acquisition de position (103) acquiert des données concernant la position du corps mobile. Une unité de commande (104) gère la mise à jour des données cartographiques par l’unité de mise à jour (102) selon les données de position obtenues par l’unité d’acquisition de position (103)
