Navigation device, method, and program
View Patent ↗In a navigation device, a destination waypoint is set by a user through an input section ( 13 ), and, when guidance to the destination waypoint is started, a control section ( 11 ) stores positional information on the destination waypoint into a destination waypoint history table ( 21 ) of a storage section ( 12 ) at predetermined timing, the destination waypoint history table ( 21 ) storing positional information on destination waypoints. Stored information is displayed on a display section ( 14 ) when the user sets a destination waypoint. The user can select a destination waypoint based on the displayed information and set the destination waypoint. After the destination waypoint is set, only the destination waypoint satisfying predetermined conditions is stored.
1. A navigation device for providing guidance from a user's current location to a set destination waypoint, characterized by comprising:
destination waypoint setting means for setting a destination waypoint;
history storing means for storing positional information on destination waypoints and the latest dates when the stored destination waypoints were used for guidance therein;
storage controlling means in response to an instruction for guidance start to the set destination waypoint, for checking the history storing means if the set destination waypoint is already stored in the history storing means, if yes, renewing the latest date (S 7 ) for the set destination waypoint in the history storing means and if not, storing positional information on the set destination waypoint in the history storing means at a predetermined timing (S 9 );
displaying means for displaying the positional information stored in the history storing means; and
destination waypoint selection means for selecting a destination waypoint with referring to the displayed positional information.
2. The navigation device according to claim 1 , characterized in that the predetermined timing refers to a timing when guidance starts for the set destination waypoint and the history storing means determines whether guidance starts for the set destination waypoint and stores positional information on the set destination waypoints therein.
3. The navigation device according to claim 1 , characterized in that the predetermined timing refers to a timing when a vehicle reaches a predetermined spot on the route to the destination waypoint and the storage controlling means determines whether the vehicle reaches the predetermined spot and stores positional information on the set destination waypoints in the history storing means.
4. A navigation device for providing guidance from a user's current location to a set destination waypoint, characterized by comprising:
destination waypoint setting means for setting destination waypoints;
history storing means for storing positional information on the set destination waypoints therein;
storage controlling means for storing positional information on destination waypoints in the history storing means at a predetermined timing when destination waypoints are set by the destination waypoint setting means and guidance starts;
displaying means for displaying the positional information stored in the history storing means; and
destination waypoint selection means for selecting a destination waypoint with referring to the displayed positional information,
further characterized in that the predetermined timing refers to a timing when a predetermined time has passed since guidance started for the set destination waypoint and the history storing means determines whether the predetermined time has passed and stores positional information on the set destination waypoints therein.
5. The navigation device according to claim 1 , characterized in that the storage controlling means selects any of the predetermined plural timings in response to user's instructions and stores positional information on destination waypoints in the history storing means at the selected timing.
