Abstract

A vehicle navigation system (e.g., GPS) with multi-use display generator that provides for the switching of a displayed image from a navigational based image to a non-navigational image such as a favorite photo. This versatility allows for the user of a vehicle navigation to avoid having to look at a boring display of map images and instead view more desirable non-navigation images such as full 100% displays of a favorite photo shot. Also if the system is in a map image mode and the user does not utilize any portion of the vehicle navigation system for a predetermined period of time an automated switchover system is provided to cause a predetermined or randomly chosen favorite photo to appear on the display. An addition option of the system is to provide an automatic switchover to the favorite display mode whenever a determination is made by the system that it will not be needed for a long period such as when the user is on a long country road or when the destination is inputted and there are no options that will arise for an extended period. Various display modes are also featured that enable greater non-navigation display mode options and activation choices.

Claims

1. A vehicle navigation system with a multi-use display, comprising:

navigation data supply means for supplying navigation data;

non-navigation data supply means for supplying non-navigation data;

image display means for displaying one or both of a navigation image display and a non-navigation image display, derived, respectively, from said navigation data and said non-navigation data; and

switchover means for automatic selection amongst a navigation mode and a non-navigation mode, with said navigation mode providing for a display of said navigation data on said display means and said non-navigation mode providing for a display of said non-navigation data on said display means, and wherein said automatic selection by said switchover means is carried out based on a necessity level review for presenting navigation data for display by said display means.

2. The vehicle navigation system according to claim 1, further comprising:

a communication port for inputting from an external resource non-navigation data to said non-navigation data supply means.

3. The vehicle navigation system according to claim 2, wherein

said communication port is a physical connector port and arranged in a front face housing of said display means.

4. The vehicle navigation system according to claim 2, wherein

said communication port is a physical connector port and arranged in a support structure which supports said display means.

5. The vehicle navigation system according to claim 2, wherein

said communication port is a wireless communication port.

6. The vehicle navigation system according to claim 1, wherein

the vehicle navigation system is installed in a vehicle, and said display means is mounted on a dashboard of the vehicle.

7. The vehicle navigation system according to claim 1 wherein

said switchover means further comprises a toggle type manual mode selector for switching back and forth between said navigation mode and said non-navigation mode.

8. The vehicle navigation system according to claim 1, wherein

said switchover means further comprises a touch screen manual trigger mode selector for triggering a switching in modes presented by said display means.

9. The vehicle navigation system according to claim 1, wherein

said display means displays the navigation data while the system is in said navigation mode together with the non-navigation data displayed as a reduced in size image relative to the navigation data display.

10. The vehicle navigation system according to claim 1 wherein

said switchover means automatically converts said navigation mode to said non-navigation mode upon determination in said necessity level review of a non-necessity for presenting navigation data.

11. The vehicle navigation system according to claim 10, wherein

said switchover means determines said non-necessity in a case where an estimated time to a next potential navigation point is larger than a preset time.

12. The vehicle navigation system according to claim 10, wherein

the switchover means determines said non-necessity in a case where an estimated distance to a next potential navigation point is larger than a preset distance.

13. The vehicle navigation system according to claim 10, wherein

said switchover means changes from said non-navigation mode back to said navigation image mode upon a determination in said necessity level review of a necessity for presenting navigation data.

14. The vehicle navigation system according to claim 1, wherein

said non-navigation data includes photo or picture image data.

15. The vehicle navigation system according to claim 1 wherein said switchover means automatically selects said navigation mode upon a determination in said necessity level review that there is a necessity for presenting navigation data.

16. The vehicle navigation system according to claim 15, wherein

said switchover means determines said necessity in the case where an estimated distance to a next potential navigation point is smaller than a preset distance.

17. The vehicle navigation system according to claim 16, wherein

said preset distance is set larger as a current vehicle speed or an average vehicle speed over an earlier period of time is larger.

18. The vehicle navigation system according to claim 15, wherein

said switchover means determines said necessity in the case where an estimated time to a next potential navigation point is smaller than a preset time.

19. The vehicle navigation system according to claim 18, wherein

said preset time is set larger as a current vehicle speed or an average vehicle speed over an earlier period of time is larger.

20. The vehicle navigation system according to claim 15 wherein

said switchover means determines said necessity when a potential vehicle control problem is detected.

21. The vehicle navigation system according to claim 20 wherein

said navigation data display on said display means includes a vehicle service direction mapping.
