Abstract

In one embodiment, a controller of a local vehicle receives data from a remote vehicle that indicates a location and direction of travel of a remote vehicle. The controller determines a roadway path of travel of the remote vehicle using map data and the data received from the remote vehicle. The controller determines a roadway path of travel of the local vehicle using the map data and data indicative of a location and direction of travel of the local vehicle. The controller also determines whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect. The controller further provides an alert, in response to determining that the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect.

Claims

1. A method, comprising:

receiving, at a controller of a local vehicle, data from a remote vehicle that indicates a location and direction of travel of a remote vehicle;

determining, by the controller, a roadway path of travel of the remote vehicle using map data and the data received from the remote vehicle;

determining, by the controller, a roadway path of travel of the local vehicle using the map data and data indicative of a location and direction of travel of the local vehicle;

determining, by the controller, whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect; and

providing, by the controller, an alert, in response to determining that the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect.

2. The method of claim 1, wherein determining whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect comprises:

identifying, by the controller, a non-intersecting roadway feature from the map data in the roadway paths of travel of the local and remote vehicles; and

suppressing, by the controller, the alert, in response to identifying the non-intersecting roadway feature.

3. The method of claim 2, wherein the non-intersecting roadway feature comprises at least one of:

a roadway overpass, a roadway cloverleaf, a roadway curvature, or a roundabout.

4. The method of claim 1, wherein the data indicative of a location and direction of travel of the local vehicle comprises global positioning system (GPS) data.

5. The method of claim 1, wherein the intersecting roadway paths of travel of the local and remote vehicles comprise at least one of:

a sloped entry intersection, a roadway curvature, or a sloped roadway in which the remote vehicle is stopped.

6. The method as in claim 1, wherein the data indicative of a location and direction of travel of the local vehicle is received by the controller via an Advanced Driver Assistance Systems Interface Specifications (ADASIS) message.

7. The method as in claim 1, further comprising:

identifying, by the controller, an upcoming built-up area associated with the roadway path of travel of the local vehicle; and

, in response,

increasing, by the controller, a transmission power used to transmit the data regarding the location and direction of travel of the local vehicle to the remote vehicle.

8. The method as in claim 1, further comprising:

determining, by the controller, an estimated time to crash between the local and remote vehicles.

9. The method as in claim 1, wherein the alert is provided to at least one of:

an electronic display, a braking system of the local vehicle, or a steering system of the local vehicle.

10. A system, comprising:

a processor; and

a memory configured to store a process executable by the processor, the process when executed by the processor operable to;

receive data from a remote vehicle that indicates a location and direction of travel of a remote vehicle;

determine a roadway path of travel of the remote vehicle using map data and the data received from the remote vehicle;

determine a roadway path of travel of a local vehicle using the map data and data indicative of a location and direction of travel of the local vehicle;

determine whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect; and

provide an alert, in response to determining that the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect.

11. The system of claim 10, wherein whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect is determined by:

identifying a non-intersecting roadway feature from the map data in the roadway paths of travel of the local and remote vehicles; and

suppressing the alert, in response to identifying the non-intersecting roadway feature.

12. The system of claim 11, wherein the non-intersecting roadway feature comprises at least one of:

a roadway overpass, a roadway cloverleaf, a roadway curvature, or a roundabout.

13. The system of claim 10, further comprising:

a global positioning system (GPS) receiver, wherein the data indicative of a location and direction of travel of the local vehicle comprises data received by the GPS receiver.

14. The system of claim 10, wherein the intersecting roadway paths of travel of the local and remote vehicles comprise at least one of:

a sloped entry intersection, a roadway curvature, or a sloped roadway in which the remote vehicle is stopped.

15. The system of claim 10, wherein the data indicative of a location and direction of travel of the local vehicle is received by the controller via an Advanced Driver Assistance Systems Interface Specifications (ADASIS) message.

16. The system of claim 10, wherein the process when executed is further operable to:

identify an upcoming built-up area associated with the roadway path of travel of the local vehicle; and

, in response,

increase a transmission power used to transmit the data regarding the location and direction of travel of the local vehicle to the remote vehicle.

17. The system of claim 10, wherein the process when executed is further operable to:

determine an estimated time to crash between the local and remote vehicles.

18. The system of claim 10, wherein the alert is provided to at least one of:

an electronic display, a braking system of the local vehicle, or a steering system of the local vehicle.

19. A tangible, non-transitory, computer-readable media having software encoded thereon, the software when executed by a processor operable to:

receive data from a remote vehicle that indicates a location and direction of travel of a remote vehicle;

determine a roadway path of travel of the remote vehicle using map data and the data received from the remote vehicle;

determine a roadway path of travel of a local vehicle using the map data and data indicative of a location and direction of travel of the local vehicle;

determine whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect; and

provide an alert, in response to determining that the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect.

20. The computer-readable media of claim 19, wherein whether the roadway path of travel of the local vehicle and the roadway path of travel of the remote vehicle intersect is determined by:

identifying a non-intersecting roadway feature from the map data in the roadway paths of travel of the local and remote vehicles; and

suppressing the alert, in response to identifying the non-intersecting roadway feature.
