A boot device, a boot method, and a boot program

Abstract

The present invention relates to a boot device, a boot method, and a bootstrap program. The vehicle information device (1) includes: a map information DB (161) for storing map information; an update information acquisition unit (171) for obtaining update information for updating the map information from the center apparatus (2); a map information update unit (173) for acquiring temporary distribution information that is used in the guidance before the completion of the update and which is the same data structure as the map information and which can be replaced with the map information, and the data recording unit (173) is configured to update the map information based on the update information; (16) for storing the temporary distribution information acquired by the temporary distribution information acquisition unit (173), and a guidance unit (174) for guiding the temporary distribution information stored in the data recording unit (16) before the update is completed, After the update is completed, the map information is updated based on the map information updated by the map information update unit (172).

Description

technical field [0001] The invention relates to a guiding device, a guiding method and a guiding program. Background technique [0002] Conventionally, as a technique for guiding a driving route, a system is known in which a client side guides a driving route generated based on map information on a server side. [0003] However, in this system, if the version of the map information differs between the server side and the client side, there is a possibility that the information generated by the server side cannot be correctly guided on the client side due to insufficient information for guidance. driving path. [0004] Therefore, as a technique for accurately guiding the travel route generated by the server on the client side, a system for updating map information on the client side to provide guidance has been proposed (for example, refer to Patent Document 1 and Patent Document 2). [0005] Patent Document 1: Japanese Patent Laid-Open No. 2014-20852 [0006] Patent Docum...

AI Technical Summary

Problems solved by technology

Therefore, it takes a relatively long time to update the map information on the client side. In the relatively long time before the update of the map information on the client side is completed, the map information cannot be used for driving route guidance, and it may not be possible to use the map information on the client side. Guidance to quickly start the travel path in the end side
