Abstract

The present invention relates to a vehicle navigation system that uses a portable information terminal. The navigation system displays route guidance information by receiving GPS satellite radio waves, and includes a navigation unit that generates route guidance information, a meter panel of a meter unit, which displays only part of the route guidance information, and a display panel of the navigation unit, which displays every selected item of the route guidance information. The meter panel of the meter unit is disposed within the visual field of the driver when in driving the vehicle. On the other hand, the display panel of the navigation unit is disposed outside of the visual field of the driver when in driving the vehicle. The resulting configuration provides a vehicle navigation system that can provide the driver with the minimum necessary information when driving the vehicle, along with additional detailed information when needed, combined in a system that affords excellent operability.

Claims

a navigation unit that generates said route guidance information;

a first display block that displays only part of said route guidance information; and

a second display block that displays every selected item of said route guidance information.

2. The vehicle navigation system according to claim 1, wherein said first display block is disposed within a visual field of the driver when driving said vehicle, and said second display block is disposed outside of said visual field of said driver when driving said vehicle.

3. The vehicle navigation system according to claim 1, wherein said first display block displays at least either a distance of or a direction to a predetermined goal.

4. The vehicle navigation system according to claim 1, wherein said first display block is part of a vehicle meter panel.

5. The vehicle navigation system according to claim 1, wherein said route guidance information displayed on said second display block includes map information.

6. The vehicle navigation system according to claim 1, wherein said navigation unit is a portable information terminal in which a navigation program is installed, and said second display block is a display panel of said portable information terminal.

7. The vehicle navigation system according to claim 6, wherein said navigation unit is housed in a container with a cover.

8. The vehicle navigation system according to claim 6, wherein said navigation unit is fixed at said vehicle so as to be removed mechanically and connected to said first display block so as to be turned on/off electrically.

9. The vehicle navigation system according to claim 7, wherein said container with a cover is fixed on or around a carrier of said vehicle.

10. The vehicle navigation system according to claim 7, wherein said container with a cover is an existing trunk provided at the rear or at a side of said vehicle.

11. The vehicle navigation system according to claim 7, wherein said container with a cover is a housing box provided under a seat of said vehicle and enabled to be used as said cover.

12. The vehicle navigation system according to claim 7, wherein said container with a cover is a leg shielding pocket with a cover, provided on the driver side wall of a leg shield extended downward from the handlebars of a scooter.

13. The vehicle navigation system according to claim 7, wherein said container with a cover is a glove compartment disposed between a cowling extended to the rear from the front of said vehicle and the body of said vehicle.

14. A vehicle navigation system that displays route guidance information by receiving GPS satellite radio waves, comprising:

a navigation unit that generates said route guidance information;

a first display block that displays said route guidance information roughly; and

a second display block that displays said route guidance information in detail.

15. The vehicle navigation system according to claim 14, wherein said first display block is disposed within a visual field of the driver when driving said vehicle, and said second display block is disposed outside of said visual field of said driver when driving said vehicle.

16. The vehicle navigation system according to claim 14, wherein said first display block displays at least either a distance of or a direction to a predetermined goal.

17. The vehicle navigation system according to claim 14, wherein said first display block is part of a vehicle meter panel.

18. The vehicle navigation system according to claim 14, wherein said route guidance information displayed on said second display block includes map information.

19. The vehicle navigation system according to claim 14, wherein said navigation unit is a portable information terminal in which a navigation program is installed, and said second display block is a display panel of said portable information terminal.

20. The vehicle navigation system according to claim 19, wherein said navigation unit is housed in a container with a cover.

21. A vehicle navigation system that displays route guidance information by receiving GPS satellite radio waves, comprising:
