Abstract

A method of operation of a navigation system includes: obtaining a device state having a current location, a current speed, and a current heading for locating a device; identifying an anticipated maneuver point for estimating a future location of the device on a thoroughfare with the anticipated maneuver point calculated from the current location and the current heading; determining an expected maneuver at the anticipated maneuver point; and generating an accessory control for manipulating an accessory on the device for the expected maneuver at the anticipated maneuver point.

Claims

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

obtaining a state for representing a device, the state including a current location, a current speed, and a current heading for locating the device with a vehicle;

identifying an anticipated maneuver point for estimating a future location of the device on a thoroughfare with the anticipated maneuver point calculated from the current location and the current heading;

determining an expected maneuver at the anticipated maneuver point; and

generating an accessory control for directing a camera on the vehicle for the expected maneuver at the anticipated maneuver point.

2. The method as claimed in claim 1 further comprising generating an overlay associated with the expected maneuver on the device.

3. The method as claimed in claim 1 wherein determining the expected maneuver includes:

estimating an arrival at the anticipated maneuver point calculated with the current location and the current speed;

identifying a further road segment connected to the anticipated maneuver point with a further current heading; and

selecting the expected maneuver based on the further road segment.

4. The method as claimed in claim 1 further comprising:

generating a planned route to a target destination for traversing the planned route with the device; and

identifying the anticipated maneuver point on the planned route.

5. The method as claimed in claim 1 further comprising:

generating a planned route to a target destination for traversing the planned route with the device;

identifying the anticipated maneuver point on the planned route; and

determining the expected maneuver at the anticipated maneuver point consistent with the planned route.

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

obtaining a state for representing a device, the state including a current location, a current speed, and a current heading for locating the device with a vehicle;

generating a planned route to a target destination for traversing the planned route with the device;

identifying an anticipated maneuver point on the planned route for estimating a future location of the device on a thoroughfare, and calculated from the current location and the current heading;

determining an expected maneuver at the anticipated maneuver point consistent with the planned route;

generating an accessory control for directing a camera on the vehicle for the expected maneuver at the anticipated maneuver point; and

generating an overlay associated with the expected maneuver on the device.

7. The method as claimed in claim 6 wherein identifying the anticipated maneuver point includes:

identifying a road segment including the current location;

identifying a shape point on the road segment in a direction of the current heading from the current location; and

assigning the shape point as the anticipated maneuver point.

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

obtaining a traffic condition associated with the road segment; and

wherein;

determining the expected maneuver includes estimating an arrival at the anticipated maneuver point calculated with the current location, the current speed, and the traffic condition.

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

determining the expected maneuver as a change in slope; and

wherein;

manipulating the accessory control includes instructing the accessory to tilt vertically.

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

determining the expected maneuver is a turn; and

wherein;

generating the accessory control includes generating an instruction to swivel the accessory horizontally.

11. A navigation system comprising:

a location module for obtaining a state for representing a device, the state including a current location, a current speed, and a current heading for locating the device with a vehicle;

a next point module, coupled to the location module, for identifying an anticipated maneuver point for estimating a future location of the device on a thoroughfare with the anticipated maneuver point calculated from the current location and the current heading;

a next action module, coupled to the next point module, for determining an expected maneuver at the anticipated maneuver point; and

a manipulation module, coupled to the next action module, for generating an accessory control for directing a camera on the vehicle for the expected maneuver at the anticipated maneuver point.

12. The system as claimed in claim 11 further comprising a display module, coupled to the next action module, for generating an overlay associated with the expected maneuver on the device.

13. The system as claimed in claim 11 wherein the next action module is for estimating an arrival at the anticipated maneuver point calculated with the current location and the current speed, for identifying a further road segment connected to the anticipated maneuver point with a further current heading, and for selecting the expected maneuver based on the further road segment.

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

a navigation module, coupled to the next action module, for generating a planned route to a target destination for traversing the planned route with the device, and

wherein;

the next action module is for identifying the anticipated maneuver point on the planned route.

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

a navigation module, coupled to the next point module, for generating a planned route to a target destination for traversing the planned route with the device; and

wherein;

the next point module is for identifying the anticipated maneuver point on the planned route; and

the next action module is for determining the expected maneuver at the anticipated maneuver point consistent with the planned route.

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

a navigation module, coupled to the next point module, for generating a planned route to a target destination for traversing the planned route with the device;

a display module coupled to the next action module for generating an overlay associated with the expected maneuver on the device;

wherein;

the next point module is for identifying the anticipated maneuver point on the planned route; and

the next action module is for determining the expected maneuver at the anticipated maneuver point consistent with the planned route.

17. The system as claimed in claim 16 wherein the next point module is for identifying a road segment including the current location, for identifying a shape point on the road segment in a direction of the current heading from the current location, and for assigning the shape point as the anticipated maneuver point.

18. The system as claimed in claim 16 wherein:

the navigation module is for obtaining a traffic condition associated with the road segment; and

the next action module is for estimating an arrival at the anticipated maneuver point calculated with the current location, the current speed, and the traffic condition.
