Navigation systems, methods, and programs acquire deviated point information regarding a deviated point where a vehicle traveling a set route has deviated the route, and acquire post-deviation travel history information regarding a travel history after a deviated vehicle has deviated the route at the deviated point. The systems, methods, and programs determine based on the post-deviation travel history information for each of the deviated vehicles whether the deviated vehicle has traveled along a reroute set after deviating the route at the deviated point, and judges whether a rate of the deviated vehicles which were determined as having traveled along the reroute is a first predetermined value or more. If the rate of the deviated vehicles which were determined as having traveled along the reroute is the first predetermined value or more, the systems, methods, and programs determine that guidance of the route is not appropriate.

A data updating system includes a navigation device running according to a predefined application program; and a server providing the navigation device with a differential data file for updating a database containing road network data. The navigation device includes a navigation memory storing a local database in an updating data format in which the road network data is arranged in the order of data types and to be updated with the differential data file; and a navigation controller that converts data stored in the local database so as to have the reference data format in which the road network data is arranged in the order of connection of the road network to be referenced to by the application program. The server includes a server controller that outputs the differential data file to be provided to the navigation device.

A map update data supply apparatus includes: isolation detection means 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; extraction means for extracting, as update required segments, segments of the update map data, 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 for generating update data files for the update target segments and the update required segments based on the update map data.

A program update device includes: a first storage unit to retain a program of a first version; a second storage unit to retain a program of a second version equal to or later than the first version; an acquiring unit to acquire a difference between the program of the second version and a program of a third version later than the second version; and an update unit to generate the program of the third version from the program of the second version that is stored in the second storage unit and the difference acquired by the acquiring unit, and to store the generated program of the third version in the first storage unit.

Map updating systems, methods, and programs that extract update requiring sections with respect to an update requesting section that is one of the sections being a target of an update request requesting that the target map data should be updated, obtain the information related to the guaranty versions respectively corresponding to the extracted update requiring sections by referring to the version table, the update requiring sections each being one of the sections that needs to be updated in order to guarantee integrity between the sections that are positioned adjacent to each other after the update requesting section has been updated, and generate, based on the update-purpose map database, one of the update data files regarding the update requesting section as well as other ones of the update data files regarding the update requiring sections and having the update versions indicated as the guaranty versions.
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.
摘要:
The invention provides a vehicle data analysis method that enables quantitative analysis of characteristics of vehicle data indicating transition in a driver's driving operation, and a vehicle data analysis system using this analysis method. A plurality of vehicle data are collected based a plurality of types of driving operations. Based on an evaluation criterion as an index for evaluating levels of the driving operations, the collected vehicle data are grouped into at least two groups. Characteristic values of the vehicle data differing between these groups are extracted.
