Abstract

A method of operation of a navigation system includes: determining a road object detection for monitoring a movement of a device; determining a travel state based on the road object detection; identifying a travel sequence involving the travel state; and determining a condition inducing movement based on matching the travel sequence to a predetermined sequence for displaying on the device.

Claims

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

determining a road object detection for monitoring a movement of a device;

determining a travel state with a control unit based on the road object detection;

identifying a travel sequence involving the travel state; and

determining a condition inducing movement based on matching the travel sequence to a predetermined sequence including a lane-level granularity movement for displaying on the device.

2. The method as claimed in claim 1 further comprising setting the condition inducing movement as the predetermined sequence of the travel state.

3. The method as claimed in claim 1 wherein determining the condition inducing movement includes matching the road object detection to the predetermined sequence for identifying a road object.

4. The method as claimed in claim 1 wherein determining the road object detection includes determining the road object detection based on detecting an acceleration, a rise count, a drop count, or a combination thereof for identifying a road object.

5. The method as claimed in claim 1 further comprising generating an object profile based on detecting an acceleration, a rise count, a drop count, or a combination thereof for identifying a road object.

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

determining a road object detection for monitoring a movement of a device for identifying a road object;

determining a travel state with a control unit based on a road object detection;

identifying a travel sequence involving the travel state;

setting a condition inducing movement as a predetermined sequence of the travel state; and

determining the condition inducing movement based on matching the travel sequence to the predetermined sequence including a lane-level granularity movement for displaying on the device.

7. The method as claimed in claim 6 wherein determining the condition inducing movement includes determining the road object detection based on matching an acceleration to an object profile for identifying the road object.

8. The method as claimed in claim 6 wherein determining the condition inducing movement includes determining the road object detection based on matching a rise count to an object profile for identifying the road object.

9. The method as claimed in claim 6 wherein determining the condition inducing movement includes determining the road object detection based on matching a drop count to an object profile for identifying the road object.

10. The method as claimed in claim 6 further comprising updating an object profile based on an acceleration, a rise count, a drop count, or a combination thereof for identifying the road object.

11. A navigation system comprising:

a detecting sensor for determining a road object detection for monitoring a movement of a device;

a control unit, coupled to the detecting sensor, for;

determining a travel state based on the road object detection,

identifying a travel sequence involving the travel state, and

determining a condition inducing movement based on matching the travel sequence to a predetermined sequence including a lane-level granularity movement for displaying on the device.

12. The system as claimed in claim 11 wherein the control unit is for setting the condition inducing movement as the predetermined sequence of the travel state.

13. The system as claimed in claim 11 wherein the control unit is for matching the road object detection to the predetermined sequence for identifying a road object.

14. The system as claimed in claim 11 wherein the detecting sensor is for determining the road object detection based on detecting an acceleration, a rise count, a drop count, or a combination thereof for identifying a road object.

15. The system as claimed in claim 11 wherein the control unit is for generating an object profile based on detecting an acceleration, a rise count, a drop count, or a combination thereof for identifying a road object.

16. The system as claimed in claim 11 wherein the detecting sensor is for determining a road object detection for monitoring a movement of a device for identifying a road object.

17. The system as claimed in claim 16 wherein the control unit is for determining the road object detection based on matching an acceleration to an object profile for identifying the road object.

18. The system as claimed in claim 16 wherein the control unit is for determining the road object detection based on matching a rise count to an object profile for identifying the road object.

19. The system as claimed in claim 16 wherein the control unit is for determining the road object detection based on matching a drop count to an object profile for identifying the road object.

20. The system as claimed in claim 16 wherein the control unit is for updating an object profile based on an acceleration, a rise count, a drop count, or a combination thereof for identifying the road object.
