摘要:
A map information delivery system, including a navigation apparatus, is capable of preferentially receiving map updating information based on a host vehicle's state. The updating information may be preferentially received based on whether a destination has been set, a location of the updating information relative to an updating position or a destination, and/or the size of the updating information.

摘要:
Map updating systems, methods, and programs that store map information, including one or more pieces of difference update information, obtain the one or more pieces of difference update information used for updating a part of the map information, and update the map information based on the one or more pieces of difference update information. The systems, methods, and programs obtain total update information used for updating an entirety of the memory to a new piece of map information, update the map information based on the total update information, compare a version of the total update information used in the total update with each of versions of the one or more pieces of difference update information stored in the memory, extract any of the one or more pieces of difference update information judged to be newer and update the map information based on the difference update information.

A map update data supply apparatus includes: isolation detection means (8) for detecting the presence and the absence of an isolated state in which some of the roads are isolated from other roads in a road network of target map data due to updating of one or more update target segments of the target map data based on update map data (Ma); extraction means (9) for extracting, as update required segments, segments of the update map data (Ma), other than the update target segments, that have a road that connects to the isolated some of the roads when it is detected that there is the isolated state; and update data file generating means (10) for generating update data files (fa) for the update target segments and the update required segments based on the update map data (Ma).
摘要:
Map information distribution systems and methods store map information and version information for each road category of the map information stored in a navigation device, the version information correlated with identification information identifying the navigation device. The systems and methods receive the identification information from the navigation device and obtain, based on the received identification information, the version information for each road category of the map information stored in the navigation device corresponding to the stored identification information. The systems and methods extract, based on the obtained version information for each road category, differential data for each road category with stored map information of a latest version, and transmit the extracted differential data for each road category to the navigation device corresponding to the received identification information.

There is provided a map information providing technology that can keep map information very fresh at all times.A map information management system has a map to be updated DB for storing map data to be updated that is used to update and maintenance, a map to be provided DB for storing map data to be provided that is distributed, an updated data DB for storing updated data for updating the map data to be provided, a map DB update means for updating the map data to be updated when the updated data for updating the map data of the map data to be updated DB is input, an updated data creation mean for creating the differential data before and after it is updated by the updated data and storing the differential data in the updated data DB as the updated data, and a data distribution means for extracting the map data to be provided or the updated data stored in the map to be provided DB when it receives a request to distribute the map data or the updated data from a destination system and distributing it to the destination system.
摘要:
To provide a data updating system and the like for easily performing updating the difference for the database which contains a large amount of data, each piece of the data being highly correlated, such as a map database that contains road network data.According to the present invention, the data updating system includes a terminal device running according to a predefined operating program, and servers providing the terminal device with a differential data file for updating a database. The terminal includes a local database in an updating data format differing from a reference data format to be referenced to by the operating program and being updated with the differential data file, and a conversion means converting data stored in the local database so as to have the reference data format. The servers include a differential data file output means outputting the differential data file to be provided to the terminal device.
摘要:
In a communication system for downloading programs from a center to in-vehicle terminals, a center can check whether downloading has been completed normally or a program is operating normally in an in-vehicle terminal. According to the timing of activating a downloaded program, an in-vehicle terminal checks whether the program is activated to operate normally. The information is transmitted to the center. Based on the information, the center becomes aware of the fact that downloading has been completed without any problem and that the program is operating normally in the in-vehicle terminal.
