Navi-server, navi-client, and navi-system
First Claim
Patent Images
1. A navi-server, comprising:
- a first server arithmetic processing element that is configured to receive, from a navi-client, probe information representing a time-series change manner of a position of the navi-client;
a second server arithmetic processing element that is configured to create road traffic information based on the probe information; and
a server storage device that stores the road traffic information, whereinthe first server arithmetic processing element is configured to receive the probe information including an identifier set to indicate a communication state between the navi-client and a device mounted on a designated travelling means or a state of attachment/detachment of the navi-client to an instrument attached to the designated travelling means, andthe second server arithmetic processing element is configured to discriminate or select the probe information in accordance with a difference of the identifier, and generate the road traffic information based on the discriminated or selected probe information.

Abstract
Provided is a navi-system or the like capable of improving accuracy of road traffic information that is created based on probe information. A navi-client 2 creates probe information including an identifier that represents a detection result as to whether a communication with a vehicle-mounted device 3 has been established or not. A server communication device 1 discriminates or selects probe information in accordance with a difference of the identifier, and creates road traffic information based on the thus discriminated or selected probe information.

7. A navi-client having a position measurement function that includes a first client arithmetic processing element that is configured to transmit probe information representing a time-series change manner of a measurement position to a navi-server, and
a second client arithmetic processing element that is configured to detect a communication state between the navi-client and a device mounted on a designated travelling means or a state of attachment/detachment of the navi-client to an instrument attached to the designated travelling means, and then create the probe information including an identifier indicating the detected communication state between the navi-client and the device or the state of attachment/detachment of the navi-client to the instrument, wherein the navi-server discriminates or selects the probe information in accordance with a difference of the identifier, and generates road traffic information based on the discriminated or selected probe information.

13. A navi-system comprising a combination of a navi-server and a navi-client, wherein
the navi-server includes: -
a first server arithmetic processing element that is configured to receive, from the navi-client, probe information representing a time-series change manner of a position of the navi-client; a second server arithmetic processing element that is configured to create road traffic information based on the probe information; and a server storage device that stores the road traffic information, wherein the first server arithmetic processing element is configured to receive the probe information including an identifier set to indicate a communication state between the navi-client and a device mounted on a designated travelling means or a state of attachment/detachment of the navi-client to an instrument attached to the designated travelling means, the second server arithmetic processing element is configured to discriminate or select the probe information in accordance with a difference of the identifier, and create the road traffic information based on the discriminated or selected probe information, and the navi-client has a position measurement function, and includes a first client arithmetic processing element that is configured to transmit probe information representing a time-series change manner of a measurement position to the navi-server, and a second client arithmetic processing element that is configured to detect the communication state between the navi-client and the device mounted on the designated travelling means or the state of attachment/detachment of the navi-client to the instrument attached to the designated travelling means, and then create the probe information including the identifier indicating the communication state between the navi-client and the device or the state of attachment/detachment of the navi-client to the instrument. - View Dependent Claims (14, 15, 16, 17, 18)
