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.

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.

In a global positioning system (GPS)/self-contained combination type navigation system for a vehicle, the GPS navigation data are received by the GPS antenna of the navigation system which are simultaneously transmitted from more than 3 pieces of satellites inclusively. From the GPS navigation data, GPS type velocity data is calculated, whereas self-contained type velocity data is calculated from self-contained type navigation data such as azimuth data and drive-distance data of the vehicle. Only when a difference between the self-contained type velocity data and the GPS type velocity data exceeds a threshold velocity, the GPS type velocity data is voided so as to determine the present position of the vehicle.

An object of the present invention is to provide a technology capable of estimating a waiting time at an energy refilling facility for each of drive types. A center-side system includes a center-side receiver that receives, from a vehicle-side system, probe vehicle position information and drive type information that is information regarding a drive type of a probe vehicle. Then, the center-side system includes: a traffic condition estimation unit that estimates a traffic condition, which includes a drive type-classified number of vehicles, based on the probe vehicle position information and the drive type information, which are received by the center-side receiver; and a center-side transmitter that transmits, to an outside, the traffic condition estimated by the traffic condition estimation unit.

Disclosed is a 3Dimension stereoscopic display device including a video image playback device 5 for playing back a right-eye image or video image and a left-eye image or video image for three-dimensional stereoscopic display which are based on an inputted image or video image, a stereoscopic display monitor 6 for producing a three-dimensional stereoscopic display of the right-eye image or video image and the left-eye image or video image and a screen composition processing unit 4 for generating the right-eye image or video image and the left-eye image or video image in which a virtual display surface for three-dimensional stereoscopic display of the image or video image differs from the screen of the stereoscopic display monitor 6, and for outputting the right-eye image or video image and the left-eye image or video image to the video image playback device 5.
摘要:
An imitation sound generation system is provided that accurately informs a user of a road environment corresponding to a current location, by an imitation sound. A navigation apparatus, which serves as an imitation sound generation system, includes a map data storage apparatus that stores road network data including data regarding links each representing each road in a road network, a vehicle information acquiring unit that acquires a current location, and a travelling road determining unit that specifies a link to which the current location belongs. The map data storage apparatus stores a plurality of pieces of imitation sound data each being associated with each link. A controller determines a piece of imitation sound data that is associated with the link to which the current location belongs, on the basis of the plurality of pieces of imitation sound data.
