Navigation apparatus and computer program product for navigation control
First Claim
Patent Images
1. A navigation apparatus comprising:
- a current position detection device that detects a current position;
a display device;
a storage device having stored therein position information related to points used as guidance points when providing route guidance; and
a control device that controls the route guidance provided along a guided route which includes a plurality of predetermined guidance points based upon the current position detected by the position detection device and the position information related to the points stored in the storage device, wherein;
as the current position approaches a first guidance point closest to the current position, the control device calculates an angle formed by a direction from the current position to the first guidance point and a direction from the first guidance point to a second guidance point following the first guidance point, and displays an arrow bending according to the calculated angle on the display device.

1. A navigation apparatus comprising:
-
a current position detection device that detects a current position;
a display device;
a storage device having stored therein position information related to points used as guidance points when providing route guidance; and
a control device that controls the route guidance provided along a guided route which includes a plurality of predetermined guidance points based upon the current position detected by the position detection device and the position information related to the points stored in the storage device, wherein;
as the current position approaches a first guidance point closest to the current position, the control device calculates an angle formed by a direction from the current position to the first guidance point and a direction from the first guidance point to a second guidance point following the first guidance point, and displays an arrow bending according to the calculated angle on the display device. - View Dependent Claims (3, 5, 6)
the control device does not display a roadmap at the display device.
-
-
5. A navigation apparatus according to claim 1, wherein:
the control device displays a straight arrow at the display device while the current position is still distanced from the next guidance point.
-
6. A navigation apparatus according to claim 1, wherein:
if another road intersects the guided route between the current position and the first guidance point, the control device brings up a supplementary indicator on display corresponding to the intersecting road between an arrow tail and a bending point.
-
2. A navigation apparatus comprising:
-
a current position detection device that detects a current position of a vehicle;
a display device;
a storage device having stored therein position information related to points used as guidance points when providing route guidance; and
a control device that controls the route guidance provided alone a guided route which includes a plurality of predetermined guidance points based upon the current position detected by the position detection device and the position information related to the points stored in the storage device, wherein as the current position approaches a first guidance point closest to the current position, the control device calculates an angle formed by a direction from the current position to a second guidance point following the first guidance point and a direction alone which the vehicle is advancing, and displays an arrow bending according to the calculated angle on the display device. - View Dependent Claims (4, 11, 12)
the control device does not display a roadmap at the display device.

-
11. A navigation apparatus according to claim 2, wherein:
the control device displays a straight arrow at the display device while the current position is still distanced from the next guidance point.
-
12. A navigation apparatus according to claim 2, wherein:
if another road intersects the guided route between the current position and the first guidance point, the control device brings up a supplementary indicator on display corresponding to the intersecting road between an arrow tail and a bending point.

7. A computer-readable computer program product containing a navigation control program, the navigation control program comprising:
-
a current position detection instruction code for detecting a current position;
a position information acquisition instruction code for obtaining position information related to points used as guidance points in route guidance; and
a route guidance control instruction code for controlling the route guidance provided along a guided route that contains a plurality of predetermined guidance points based upon the current position detected in conformance to the current position detection instruction code and the position information related to the points obtained in conformance to the position information acquisition instruction code, wherein;
in conformance to the route guidance control instruction code, control is implemented so that as the current position approaches the first guidance point closest to the current position, an angle formed by a direction from the current position to the first guidance point and a direction from the first guidance point to a second guidance point following the first guidance point is calculated, and an arrow bending according to the calculated angle is displayed at a display device. - View Dependent Claims (8, 9, 10)
in conformance to the route guidance control instruction code in the navigation control program, control is implemented so as not to display a roadmap at the display device.

9. A computer program product according to claim 7, which is a recording medium having recorded therein the navigation control program.
-
10. A computer program product according to claim 7, which is a carrier wave having the navigation control program embodied as a data signal therein.
-
13. A computer-readable computer program product containing a navigation control program, the navigation control program comprising:
-
a current position detection instruction code for detecting a current position of a vehicle;
a position information acquisition instruction code for obtaining position information related to points used as guidance points in route guidance; and
a route guidance control instruction code for controlling the route guidance provided along a guided route that contains a plurality of predetermined guidance points based upon the current position detected in conformance to the current position detection instruction code and the position information related to the points obtained in conformance to the position information acquisition instruction code, wherein;
in conformance to the route guidance control instruction code, control is implemented so that as the current position approaches the first guidance point closest to the current position, an angle formed by a direction from the current position to a second guidance point following the first guidance point and a direction along which the vehicle is advancing is calculated, and an arrow bending according to the calculated angle is displayed at a display device. - View Dependent Claims (14, 15, 16)
