Abstract

A method of operation of a navigation system includes: detecting a light intensity; and selecting a route determined by the light intensity for displaying on a device.

Claims

1. A method of operation of a navigation system comprising:

detecting a light intensity; and

selecting a route determined by the light intensity for displaying on a device.

2. The method as claimed in claim 1 further comprising sending a data request for the light intensity.

3. The method as claimed in claim 1 further comprising estimating a potential travel distance with the light intensity.

4. The method as claimed in claim 1 further comprising presenting a notification based on the light intensity.

5. The method as claimed in claim 1 further comprising calculating an estimated remaining power level with the light intensity.

6. A method of operation of a navigation system comprising:

receiving a current power level;

detecting a light intensity based on the current power level; and

selecting a route determined by the light intensity for displaying on a device.

7. The method as claimed in claim 6 further comprising comparing a predetermined minimum power level to the current power level.

8. The method as claimed in claim 6 further comprising identifying a power replenishment location along the route.

9. The method as claimed in claim 6 further comprising re-calculating the route based on a low light intensity indicator.

10. The method as claimed in claim 6 further comprising re-calculating the route based on a time change indicator.

11. A navigation system comprising:

a control unit for detecting a light intensity; and

a location unit, coupled to the control unit, for selecting a route determined by the light intensity for displaying on a device.

12. The system as claimed in claim 11 further comprising a user interface, coupled to the location unit, for sending a data request for the light intensity.

13. The system as claimed in claim 11 wherein the control unit is for estimating a potential travel distance with the light intensity.

14. The system as claimed in claim 11 further comprising a user interface, coupled to the location unit, for presenting a notification based on the light intensity.

15. The system as claimed in claim 11 wherein the control unit is for calculating an estimated remaining power level with the light intensity.

16. The system as claimed in claim 11 further comprising a user interface, coupled to the location unit, for receiving a current power level, the light intensity based on the current power level.

17. The system as claimed in claim 16 wherein the control unit is for comparing a predetermined minimum power level to the current power level.

18. The system as claimed in claim 16 wherein the control unit is for identifying a power replenishment location along the route.

19. The system as claimed in claim 16 wherein the control unit is for re-calculating the route based on a low light intensity indicator.

20. The system as claimed in claim 16 wherein the control unit is for re-calculating the route based on a time change indicator.
