Abstract

A method of operation of a navigation system with location profiling includes: calculating a routing region based on a current location for locating a device; calculating a familiarity level in the routing region; generating a routing overlay based on the familiarity level below a familiarity threshold with the routing overlay to compensate for a driver unfamiliarity in the routing region; and generating a compensation route based on the routing overlay for displaying on the device.

Claims

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

calculating, with a control unit a routing region based on a current location for locating a device, the routing region is a geographic area;

calculating a familiarity level in the routing region;

generating a routing overlay based on the familiarity level below a familiarity threshold with the routing overlay to compensate for a driver unfamiliarity in the routing region; and

generating a compensation route from multiple routes in the routing region based on the routing overlay for displaying on the device.

2. The method as claimed in claim 1 wherein calculating the familiarity level in the routing region includes:

retrieving a driver history for the routing region; and

calculating the familiarity level based on the driver history below the familiarity threshold.

3. The method as claimed in claim 1 wherein calculating the familiarity level includes varying the familiarity threshold to compensate for the difficulty of the routing region.

4. The method as claimed in claim 1 wherein generating the routing overlay includes updating supplemental routing information based on an environment profile for the routing region for compensating for an environmental effect.

5. The method as claimed in claim 1 wherein generating the routing overlay includes:

updating supplemental routing information based on a driver preference; and

overriding the routing overlay with the driver preference.

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

calculating, with a control unit a routing region based on a current location for locating a device, the routing region is a geographic area;

retrieving a driver history for the routing region;

varying a familiarity threshold based on the nature of the routing region;

calculating a familiarity level for the routing region based on the driver history;

generating a routing overlay based on the familiarity level below the familiarity threshold with the routing overlay to compensate for a driver unfamiliarity at the routing region; and

generating a compensation route from multiple routes in the routing region based on the routing overlay for displaying on the device.

7. The method as claimed in claim 6 further comprising:

detecting a navigation event for the current location;

comparing the current location to the compensation route; and

updating the driver history based on the current location not being on the compensation route.

8. The method as claimed in claim 6 further comprising updating the driver history with a driver performance along the compensation route.

9. The method as claimed in claim 6 wherein generating the compensation route based on the routing overlay includes generating the compensation route with the lowest cost based on the familiarity level.

10. The method as claimed in claim 6 wherein calculating the routing region based on the current location includes calculating the routing region based on a start location and an end location.

11. A navigation system comprising:

a location unit for;

calculating a current location for a device;

a profile engine, coupled to the location unit, includes;

a calculate routing region module for calculating a routing region based on the current location, the routing region is a geographic area,

a get driver history module for calculating a familiarity level in the routing region, and

a generate routing overlay module for generating a routing overlay having supplemental routing information based on the familiarity level being below a familiarity threshold with the routing overlay to compensate for an unfamiliarity of the driver at the routing region;

a routing engine, coupled to the profile engine, for;

generating a compensation route from multiple routes in the routing region based on the routing overlay; and

a control unit, coupled to the routing engine, for;

sending the compensation route for displaying on a device.

12. The system as claimed in claim 11 wherein the get driver history module is for retrieving a driver history for the routing region and for calculating the familiarity level based on the driver history below the familiarity threshold.

13. The system as claimed in claim 11 wherein the profile engine is for varying the familiarity threshold to compensate for the difficulty of the routing region.

14. The system as claimed in claim 11 wherein the profile engine is for updating supplemental routing information of the routing region based on an environment profile for the routing region for compensating for an environmental effect.

15. The system as claimed in claim 11 wherein the generate routing overlay module is for updating the supplemental routing information based on a driver preference and for overriding the routing overlay with the driver preference.

16. The system as claimed in claim 11 wherein the get driver history module is for retrieving a driver history for the routing region, for varying the familiarity threshold based on the nature of the routing region, and for calculating the familiarity level for the routing region based on the driver history.

17. The system as claimed in claim 16 wherein:

the location unit is for detecting a navigation event for the current location; and

the control unit includes a navigate route module for comparing the current location to the compensation route and for updating the driver history based on the current location not being on the compensation route.

18. The system as claimed in claim 16 wherein the profile engine is for updating the driver history with a driver performance along the compensation route.

19. The system as claimed in claim 16 wherein the routing engine is for generating the compensation route with the lowest cost based on the familiarity level.

20. The system as claimed in claim 16 wherein the profile engine is for calculating the routing region based on a start location and an end location.
