Abstract

A method of operation of a navigation system includes: detecting a vehicle abrupt maneuver; scanning a vehicle environment for a road hindrance; identifying a cause of the vehicle abrupt maneuver based on the vehicle environment; determining a classification as a provoked maneuver or an unprovoked maneuver based on the cause; and generating a message based on the classification and the cause for displaying on a device.

Claims

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

detecting a vehicle abrupt maneuver;

scanning a vehicle environment for a road hindrance;

identifying a cause of the vehicle abrupt maneuver based on the vehicle environment;

determining a classification as a provoked maneuver or an unprovoked maneuver based on the cause; and

generating a message based on the classification and the cause for displaying on a device.

2. The method as claimed in claim 1 wherein identifying the cause of the vehicle abrupt maneuver based on the vehicle environment includes:

identifying a maneuver location for the vehicle abrupt maneuver; and

detecting the road hindrance in proximity to the maneuver location.

3. The method as claimed in claim 1 wherein determining the classification as the provoked maneuver or unprovoked maneuver includes:

detecting the road hindrance as the cause of the vehicle abrupt maneuver; and

determining the classification as the provoked maneuver based on the cause.

4. The method as claimed in claim 1 wherein determining the classification as the provoked maneuver or unprovoked maneuver includes:

identifying the road hindrance as not the cause based on the road hindrance and a maneuver location; and

determining the classification as the unprovoked maneuver.

5. The method as claimed in claim 1 further comprising generating a report containing the cause, the classification, or a combination thereof.

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

detecting a vehicle abrupt maneuver and a maneuver location;

scanning a vehicle environment for a road hindrance;

identifying a cause of the vehicle abrupt maneuver based on the maneuver location and the road hindrance;

determining a classification as a provoked maneuver or an unprovoked maneuver based on the cause;

generating a report containing the cause and the classification; and

generating a message based on the classification for displaying on a device.

7. The method as claimed in claim 6 wherein:

scanning the vehicle environment for the road hindrance includes identifying a hindrance type for the road hindrance; and

generating the message based on the classification includes generating the message to avoid the hindrance type.

8. The method as claimed in claim 6 wherein generating the message includes generating a safety recommendation based on the cause and the classification.

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

identifying the road hindrance as not related to the cause based on the vehicle abrupt maneuver and the maneuver location; and

wherein;

determining the classification includes determining the classification as the unprovoked maneuver; and

generating the message includes generating a safety recommendation to slow down, pull over, or a combination thereof.

10. The method as claimed in claim 6 further comprising requesting information from a safety camera to monitor the vehicle environment.

11. A navigation system comprising:

an abrupt maneuver module, for detecting a vehicle abrupt maneuver;

a road hindrance module, coupled to the abrupt maneuver module, for scanning a vehicle environment for a road hindrance;

a determine cause module, coupled to the road hindrance module, for identifying a cause of the vehicle abrupt maneuver based on the vehicle environment;

a determine classification module, coupled to the determine cause module, for determining a classification as a provoked maneuver or an unprovoked maneuver based on the cause; and

a generate message module, coupled to the determine classification module, for generating a message based on the classification and the cause for displaying on a device.

12. The system as claimed in claim 11 further comprising:

an identify maneuver location module, coupled to the determine cause module, for identifying a maneuver location for the vehicle abrupt maneuver;

a check proximity module, coupled to the identify maneuver location module, for detecting the road hindrance in proximity to the maneuver location; and

wherein;

the determine cause module, coupled to the check proximity module, is for determining the cause based on the vehicle abrupt maneuver, the maneuver location, and the road hindrance in proximity to the maneuver location.

13. The system as claimed in claim 11 wherein:

the determine cause module is for detecting the road hindrance as the cause of the vehicle abrupt maneuver; and

the determine classification module is for determining the classification as the provoked maneuver based on the cause.

14. The system as claimed in claim 11 wherein:

the determine cause module is for identifying the road hindrance as not the cause based on the road hindrance and a maneuver location; and

the determine classification module is for determining the classification as the unprovoked maneuver.

15. The system as claimed in claim 11 further comprising a generate report module, coupled to the generate message module, for generating a report containing the cause, the classification, or a combination thereof to a recipient.

16. The system as claimed in claim 11 wherein:

the abrupt maneuver module is for detecting the vehicle abrupt maneuver and the maneuver location;

the determine cause module is for identifying the cause of the vehicle abrupt maneuver based on the maneuver location and the road hindrance; and

further comprising;

a generate report module for generating a report containing the cause and the classification.

17. The system as claim in claim 16 wherein:

the road hindrance module is for identifying a hindrance type for the road hindrance; and

the generate message module is for generating a message to avoid the hindrance type.

18. The system as claim in claim 16 wherein the generate message module is for generating a safety recommendation based on the cause and the classification.

19. The system as claim in claim 16 wherein:

the determine cause module is for identifying the road hindrance as not related to the cause based on the vehicle abrupt maneuver and the maneuver location;

the determine classification module is for determining the classification as the unprovoked maneuver; and

the generate message module is for generating a safety recommendation to slow down, pull over, or a combination thereof.

20. The system as claim in claim 16 further comprising a scan environment module, coupled to the generate message module, for requesting information from a safety camera to monitor the vehicle environment.
