Problems solved by technology

[0006] However, in the map differential data distribution device disclosed in Patent Document 1, the combination of map differential data is not considered, so it is difficult to realize the distribution of a plurality of modes in which the map differential data to be distributed differs in combination.

Deformed example 2

[0165] In Embodiment 1, the distribution timing is set in the management table, but it is not necessarily limited to this. For example, a configuration may be adopted in which no distribution timing is set in the management table. In this case, for example, the distribution time point of the difference group to be distributed may be uniformly set to the above-mentioned distribution time point "normal".

[0166]

[0167] In Embodiment 1, the structure provided with the model table was shown, but it is not necessarily limited to this. For example, a configuration in which no model sheet is provided may also be used. In other words, there may be a configuration in which no distinction is made in the combination of difference groups to be distributed (in other words, map difference data) even if the request status and distribution area are different. In this case, it is only necessary to set a different configuration of the management table for each distribution target classif...

Deformed example 5

[0171] In Embodiment 1, the map differential data distribution system 100 does not include a server (hereinafter, map differential data generation server) that generates map differential data from map data before and after the update every time the map data is updated, but It doesn't have to be limited to this. For example, a map differential data generating server may be included in the map differential data distribution system 100 . Alternatively, the map difference data creation server, the map difference extraction server 1 , and the update management server 2 may be integrated.

[0172] The above-mentioned disclosure includes the following aspects.

[0173] The map differential data distribution device 1 according to the first aspect of the present disclosure includes a map differential data storage unit 12 , a distribution unit 137 for distributing map differential data, a pattern storage unit 13 , and a distribution object extraction unit 141 . The map differential da...

Abstract

The map differential data distribution device includes a map differential data storage unit (12), a distribution unit (137) for distributing map differential data, a pattern storage unit (13), and a distribution object extraction unit (141). The map difference data storage unit stores the difference data of the data of the map elements of the map data before and after the update, and the dependent objects that have a dependency relationship in which the map elements do not match other map elements unless they are updated in advance. The data of the map elements in is used as map difference data. The pattern storage unit stores in advance a plurality of patterns for storing a combination of map difference data to be distributed, that is, a distribution pattern. The distribution target extracting unit extracts map differential data corresponding to a distribution destination as a distribution target from the map differential data according to a plurality of distribution modes. The distribution unit distributes the extracted map differential data and map differential data of dependent objects in a dependent relationship with the map differential data.

Description

[0001] This disclosure claims the priority of Japanese Application No. 2013-085994 filed on Apr. 16, 2013, and the contents thereof are incorporated herein. technical field [0002] The present disclosure relates to a map differential data distribution device that distributes map differential data, and a map differential data distribution system including the map differential data distribution device. Background technique [0003] Conventionally, there is known a technique of distributing the difference between the map data of the version number (hereinafter, version) before updating map elements such as roads and the map data after updating map elements as map difference data to car navigation devices. The map data is updated by the map differential data in the car navigation device that receives distribution of the map differential data. [0004] For example, Patent Document 1 discloses that instead of map differential data generated in units of divisions in which a layer ...
