Navigation device for executing rerouting search and notification method
First Claim
1. A navigation device that includes a memory storing a program that, in response to execution, causes a processor to perform operations comprising:
- a determiner that determines execution of rerouting;
a notifier that notifies the execution of the rerouting when the determiner determines the execution of the rerouting;
a searcher that executes a rerouting search when the determiner determines the execution of the rerouting; and
a measurer that measures a distance of movement of the navigation device along a guide route that is a result of the rerouting search by the searcher, wherein in a case in which the determiner determines execution of next rerouting, the notifier notifies the execution of the next rerouting when the distance measured by the measurer is longer than a threshold value and does not notify the execution of the next rerouting when the distance measured by the measurer is smaller than or equal to the threshold value.

Abstract
A determiner determines execution of rerouting. A notifier notifies the execution of rerouting if the determiner determines the execution of rerouting. A searcher executes a rerouting search if the determiner determines the execution of rerouting. A measurer measures the distance by which a navigation device has moved along a guide route, which is a result of the rerouting search by the searcher. In a case in which the determiner determines execution of next rerouting, the notifier notifies the execution of rerouting if the measured distance is longer than a threshold value and does not notify the execution of rerouting if the measured distance is smaller than or equal to the threshold value.

3. A navigation device that includes a memory storing a program that, in response to execution, causes a processor to perform operations comprising:
-
a determiner that determines execution of rerouting; a notifier that notifies the execution of the rerouting when the determiner determines the execution of the rerouting; a searcher that executes a rerouting search when the determiner determines the execution of the rerouting; and a measurer that measures time of movement of the navigation device along a guide route that is a result of the rerouting search by the searcher, wherein in a case in which the determiner determines execution of next rerouting, the notifier notifies the execution of the next rerouting when the time measured by the measurer is longer than a threshold value and does not notify the execution of the next rerouting when the time measured by the measurer is smaller than or equal to the threshold value. - View Dependent Claims (4)

5. A notification method of a navigation device that includes a memory storing a program that, in response to execution, causes a processor to perform operations comprising:
-
determining execution of rerouting; notifying the execution of the rerouting when the execution of the rerouting is determined; executing a rerouting search when the execution of the rerouting is determined;
measuring a distance of movement of the navigation device along a guide route that is a result of the rerouting search; andin a case in which execution of next rerouting is determined, notifying the execution of the next rerouting when the measured distance is longer than a threshold value and not notifying the execution of the next rerouting when the measured distance is smaller than or equal to the threshold value.
