Disclosed is a charging control apparatus including: a communication unit 9 that communicates with a charge vehicle 3; an electric fee table 7 in which data that indicates a change of an electric fee with the elapse of time of a system power 4 is set; and a charging schedule processing unit 8 that acquires from the charge vehicle 3 a residual capacity of a battery 27 installed in the charge vehicle 3 via the communication unit 9, and plans a charging schedule to charge the battery 27 from the residual capacity of the battery 27 to a predetermined charge amount at the cheapest electric fee by a predetermined date and time, based on the electric fee table 7.
摘要:
A navigation apparatus displays map display contents of a mobile phone terminal 2 on a liquid crystal monitor 14 of an onboard information system 1 in the same direction as the direction of map display of the mobile phone terminal 2 in accordance with information about the map display acquired from the mobile phone terminal 2 via a short-range radio communication unit 9.
摘要:
An information processing apparatus has data management data that determines storage locations of real data in a data group in accordance with data definition information indicating a data structure of the data group, and a data access program that describes an access function to the real data whose data structure is specified in accordance with the data definition information, and gains access to the real data of the data group by executing the data access program while determining the storage locations of the real data by referring to the data management data.
摘要:
In a road data frame for displaying road maps, each node/link data record describing a link corresponding to a road part includes link identification information identifying an original link, and auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. In a route planning data frame for route planning, each connection record describing the interconnection of nodes also includes corresponding link identification information identifying an original link, and corresponding auxiliary link identification information used for identifying a plurality of alternative links which substitute for any of the original links in the map data. By means of identification information of the original link and auxiliary links, it is facilitated to identify the correlation among links in the road data frame and the route planning data frame having different versions.
摘要:
A map data processing apparatus includes: a map data storage unit, a differential data input unit, and a map data multiple update unit. The map data storage unit stores map data. The differential data input unit inputs differential data representing the difference between current map data stored in the map data storage unit and the most recent map data in a script format for each version. The map data multiple update unit updates the map data in the map data storage unit to the most recent map data using the differential data corresponding to the version.

When a car navigation unit receives a remotely inputted command transmitted from a personal digital assistant (PDA), the remotely inputted command is interpreted to generate display data. The display data is transmitted to the PDA.
摘要:
An on-vehicle information processing unit includes a central processing unit; a first device connected to the central processing unit; a device-dependent driver for driving only the first device; an operating-system-standard (OS-standard) driver enabling an application to drive devices different from the first device; a device-dependent application using the first device through the device-dependent driver; and an OS-dependent application for using the first device through the OS-standard driver. The central processing unit can include a switch for enabling the OS-dependent application only when using an Internet function, and for operating the device-dependent application in a normal mode.
