Abstract

A navigation apparatus referring to map information when a destination is input, performing a guidance according to a guidance route to the set destination, and displaying candidate site information on one or two or more candidate sites capable of stopping by after deviating from the guidance route includes: a deviation point determining unit determining a deviation point of which a route to arrive at the candidate site is a point deviating from the guidance route; a deviation information obtaining unit obtaining deviation information indicating an extent of deviation from the deviation point to the candidate site; and a display unit displaying the deviation information on the candidate site related to the candidate site information.

Claims

1. A navigation apparatus referring to map information when a destination is input, performing a guidance according to a guidance route to the set destination, and displaying candidate site information on one or two or more candidate sites capable of stopping by after deviating from the guidance route, comprising:

a deviation point determining unit determining a deviation point of which a route to arrive at the candidate site is a point deviating from the guidance route;

a deviation information obtaining unit obtaining deviation information indicating an extent of deviation from the deviation point to the candidate site; and

a display unit displaying the deviation information on the candidate site related to the candidate site information.

2. The navigation apparatus according to claim 1, wherein

the deviation information includes information on a road distance from the deviation point to the candidate site.

3. The navigation apparatus according to claim 1, wherein

the deviation information includes information on a road distance from the deviation point to a return point returning to the guidance route after traveling through the candidate site.

4. The navigation apparatus according to claim 2, wherein

the deviation information includes information on a road distance from the deviation point to a return point returning to the guidance route after traveling through the candidate site.

5. The navigation apparatus according to claim 1, wherein

the deviation information includes information on the number of guidance while traveling from the deviation point to the candidate site.

6. The navigation apparatus according to claim 1, further comprising

a separation information obtaining unit obtaining separation information indicating a linear distance or a road distance from a vehicle position to the candidate site regarding the candidate site, wherein

the display unit displays the separation information related to the candidate site information together with the deviation information.

7. The navigation apparatus according to claim 1, wherein

the display unit list-displays the candidate site information in ascending order of an extent of deviation from the deviation point to the candidate site based on the deviation information.

8. The navigation apparatus according to claim 6, wherein

the display unit list-displays the candidate site information in ascending order of a linear distance or a road distance from the vehicle position to the candidate site based on the separation information.

9. The navigation apparatus according to claim 1, further comprising,

a selecting unit selecting one from among a plurality of orders selected from the followings as an order in which the display unit list-displays the candidate site information,

(A) an order of a road distance from the deviation point to the candidate site;

(B) an order of a road distance from the deviation point to a return point;

(C) an order of the number of guidance while traveling from the deviation point to the candidate site;

(D) an order of a linear distance from a vehicle position to the candidate site;

(E) an order of a road distance from the vehicle position to the candidate site; and

wherein

the display unit list-displays the candidate site information according to the order selected by the selecting unit.

10. A navigation program referring to map information when a destination is input, performing a guidance according to a guidance route to the set destination, displaying candidate site information on a candidate site capable of stopping by after deviating from the guidance route, and causing a computer to execute the steps of:

determining a deviation point of which a route to arrive at the candidate site is a point deviating from the guidance route;

obtaining deviation information indicating an extent of deviation from the deviation point to the candidate site; and

displaying the deviation information on the candidate site related to the candidate site information.
