Abstract

When a route searching command is input, a control unit searches for a provisional route disregarding remaining energy. Next, a finding unit finds charging lanes and charging spots near the provisional route and a calculation unit calculates a charging lane traveling distance and a spot charging usage amount. Then, a searching unit searches for charging lane information, and the like, the first route that restrains charging up cost and uses charging lanes and searches for, on the basis of the spot charging usage amount, charging spot information, and the like, the second route that restrains charging up cost and uses charging spots. A generation unit generates information about the retrieved routes that includes charging up cost and the expected time required. which is presented by a presentation unit. Accordingly, it is possible to find routes including charging plans that use charging lanes and charging spots and to enhance user convenience.

First claim

1 . A route searching device that searches for a route to a destination, comprising:
a searching unit searching for a first route that gives priority to charging in a charging lane that performs charging of a battery of a moving body as said moving body travels, and a second route that gives priority to charging at a charging spot at which charging of said battery is performed in the state in which said moving body is stopped; and a generation unit generating information for presentation related to said first route and to said second route.

2 . The route searching device according to claim 1 , further comprising:
a first calculation unit calculating a charging up cost for each of said first route and said second route; wherein said generation unit further generates information for presentation related to the charging up cost for both said first route and said second route calculated by said first calculation unit.

3 . The route searching device according to claim 1 , further comprising:
a second calculation unit calculating, for both said first route and said second route, at least one of an expected time point of arrival at said destination, and an expected traveling time required for traveling to said destination; wherein said generation unit further generates information for presentation related to at least one of information for presentation related to at least one of the expected time point of arrival at said destination and the expected traveling time required for traveling to said destination via said first route, and information for presentation related to at least one of the expected time point of arrival at said destination and the expected traveling time required for traveling to said destination via said second route.

4 . The route searching device according to claim 1 , further comprising:
a finding unit finding said charging lanes and said charging spots; wherein said searching unit searches for said first route and said second route on the basis of the charging lanes and charging spots that have been found by said finding unit.

5 . A terminal device that is provided to a moving body having a battery, comprising:
a reception unit receiving information for presentation related to a first route found that gives priority to charging in a charging lane that performs charging of said battery as said moving body travels, and information for presentation related to a second route found that gives priority to charging at a charging spot at which charging of said battery is performed in the state in which said moving body is stopped; and a presentation unit presenting said information for presentation received by said reception unit.

6 . A route searching method that is employed by a route searching device that searches for a route to a destination, comprising the steps of:
a searching process of searching for a first route that gives priority to charging in a charging lane that performs charging of a battery of a moving body as said moving body travels, and a second route that gives priority to charging at a charging spot at which charging of said battery is performed in the state in which said moving body is stopped; and a generating process of generating information for presentation related to said first route and to said second route.

7 . (canceled)

8 . A non-transient computer readable medium having recorded thereon a route searching program that, when executed, causes a computer in a route searching device that searches for a route to a destination to execute the route searching method according to claim 6 .
