First Claim
1. An information-processing device, comprising:
- a current-position information acquirer for acquiring current-position information about a current-position of a mobile body;
a destination information acquirer for acquiring destination information about a position of a destination to which the mobile body travels;
a way point information acquirer for acquiring way point information about a position of a way point to which the mobile body travels;
a route search section for searching a plurality of candidate routes from the current-position of the mobile body to the destination according to the current-position information and the destination information;
a route setting section for setting one of the plurality of candidate routes as a guidance route; and
a research section for searching a new route from the current-position of the mobile body to the destination including at least a section of the guidance route as well as the way point when it is recognized that new way point information is acquired after the guidance route is set.

Abstract
A navigation device (100) has a processor (180) search by a route search section a plurality of candidate routes from a current-position to a destination according to various information, and sets one of the candidate routes as a first guidance route. When recognizing that a way point recognizer acquires way point information about a way point, the processor (180) makes a research section research a first research route from the current-position to the destination including a section of the first guidance route as well as the way point. Owing to this, the navigation device (100) can reset the first research route including at least a section of the first guidance route, i.e., the first research route reflecting the first guidance route, as a second guidance route even after the first guidance route is set.

10. An information-processing system for searching a travel route of a mobile body using a server connected to a terminal unit in a manner capable of transmitting/receiving various information over a network,
the terminal unit, comprising: -
a current-position information generator for generating current-position information about a current-position of the mobile body;
a destination information generator for generating destination information about a position of a destination to which the mobile body travels;
a way point information generator for generating way point information about a way point to which the mobile body travels;
a route setting section for acquiring route information about a candidate route from the current-position of the mobile body to the destination and for generating route setting information including an instruction to set the candidate route as a guidance route;
a terminal notification controller for controlling a notifying section that notifies the guidance route; and
a terminal transceiver for transmitting to the server the current-position information, the destination information, the way point information and the route setting information and for receiving from the server the route information over the network, the server, comprising;
a current-position information acquirer for acquiring the current-position information;
a destination information acquirer for acquiring the destination information;
a way point information acquirer for acquiring the way point information;
a route setting information acquirer for acquiring the route setting information;
a route search section for searching the candidate route according to the current-position information and the destination information and for generating route information about the candidate route;
a research section for searching a new route including at least a section of the guidance route as well as the way point and for generating the route information about a research route when recognizing that new way point information is acquired after the route setting information is acquired; and
a server transceiver for transmitting to the terminal unit the route information about the candidate route and the research route and for receiving from the terminal unit the current-position information, the destination information, the way point information and the route setting information over the network.

11. An information-processing method, comprising the steps of:
-
acquiring current-position information about a current-position of a mobile body;
acquiring destination information about a position of a destination to which the mobile body travels;
searching a candidate route from the current-position of the mobile body to the destination according to the current-position information and the destination information;
setting the candidate route as a guidance route; and
searching a new route from the current-position of the mobile body to the destination including at least a section of the guidance route as well as a way point when it is recognized that new way point information about the way point to which the mobile body travels is acquired after the guidance route is set.
