NAVIGATION DEVICE, NAVIGATION SERVER AND NAVIGATION SYSTEM
First Claim
1. A navigation device which guides a mobile body on the basis of communication with a navigation server, comprising:
- a first processing unit which recognizes a departure position and a destination position of the mobile body, and which sets and outputs a first navigation route for guiding the mobile body to the destination position; and
a second processing unit which makes the navigation server recognize the departure position and the destination position of the mobile body on the basis of communication with the navigation server, which recognizes individual link constituting a support route set by the navigation server for guiding the mobile body to the destination position, and which sets and outputs a second navigation route for guiding the mobile body to the destination position on the basis of individual link;
wherein the second processing unit sets and outputs the second navigation route including a part of the first navigation route taking a position departing from the current position of the mobile body by a first distance as a terminal point, in a condition where the first navigation route is set by the first processing unit.

Abstract
A navigation device and the like capable of harmonizing a navigation route for guiding a mobile body set on the basis of a support route search result by a navigation server and a navigation route for also guiding the mobile body set independently of the navigation route, from a view point of guiding the mobile body smoothly. In the case where the second navigation route r2 is set in the condition where the first navigation route r1 is set, the second navigation route r2 is set and output so as to include a part dr1 of the first navigation route r1 which takes a position departing from the current position pt of the automobile 2 by a first distance d1. Therefore, even in the case where the second navigation route r2 is set and output at the navigation device 200 during the time when the automobile 2 is traveling according to the first navigation route r1 output at the navigation device 200, it is possible to guide the automobile 2 according to the original first navigation route r1 until the position departing from the current position pt of the automobile 2 by the first distance d1. Therefore, it becomes possible to guide the automobile 2 smoothly to the destination position p2, without forcing the automobile 2 to perform abrupt behavior change.
