NAVIGATION SERVER, NAVIGATION APPARATUS, AND NAVIGATION SYSTEM
First Claim
1. A navigation server which is configured to support an arithmetic processing performed by a navigation apparatus mounted in a mobile device serving as a support subject on the basis of communication with the mobile device, comprising:
- a first function storing element which is configured to store a first function representing a correlation between a device identifier for identifying the mobile device, operation information representing an operation state of the mobile device, and an energy index representing an energy amount consumed by the mobile device;
a second function storing element which is configured to store a second function representing a correlation between the device identifier, a link identifier for identifying an individual link, and the energy index;
a first support processing element which is configured torecognize the device identifier of a second probe mobile device, the link identifier of an individual link where the second probe mobile device has passed, and the operation information detected by a probe device mounted in the second probe mobile device on the basis of communication with the second probe mobile device;
evaluate the energy index for each combination of the link identifier and the device identifier according to the first function on the basis of the recognition result; and
set or modify the second function on the basis of the evaluation result; and
a second support processing element which is configured torecognize the device identifier of the mobile device serving as the support subject;
evaluate the energy index for an individual link identifier according to the second function on the basis of the recognition result; and
enable the navigation apparatus mounted in the mobile device serving as the support subject to recognize the evaluation result or road traffic information defined according to the evaluation result on the basis of communication with the mobile device serving as the support subject.

Abstract
Provided is a navigation system which can contribute to guidance of a moving device such as a vehicle to a destination along a route appropriate from a viewpoint of energy economy. According to second information (VIN, Lj, OPj) on a second probe car Q2, an eco-index ECOj is evaluated for each combination of a link identifier Lj and a vehicle identifier VIN according a first function f1. According to the evaluation result, a second function f2 is set. According to support request information (VIN) on a support subject car Q, an eco-index ECOk is evaluated for an individual link identifier Lk according to the second function f2. The evaluation result or the road traffic information decided according to the evaluation result is recognized by a navigation apparatus (200) mounted on the support subject car Q.
