Abstract

A computer-implemented method for intersection control includes detecting an uncontrolled intersection ahead of the first vehicle travelling along a first road. The uncontrolled intersection includes an entry to a second road. The method includes detecting a start point of the entry and an end point of the entry with respect to the first vehicle using curb detection. The method includes predicting intent of a second vehicle to traverse through the entry, and controlling the first vehicle to allow the traversal through the entry by the second vehicle.

First claim

The invention claimed is:

1. A computer-implemented method for intersection control, comprising:
detecting an uncontrolled intersection ahead of a first vehicle traveling along a first road, wherein the uncontrolled intersection includes an entry to a second road, and detecting the uncontrolled intersection includes detecting a start point of entry and an end point of the entry with respect to the first vehicle using curb detection;
detecting a controlled intersection located along the first road and ahead of the uncontrolled intersection and the first vehicle;
receiving traffic data from the controlled intersection using a vehicle communication network;
predicting intent of a second vehicle to traverse through the entry by predicting a time of traversal based on the traffic data; and
controlling the first vehicle based on the traffic data by controlling movement of the first vehicle to stop relative to the entry to allow the traversal through the entry by the second vehicle at the time of traversal.

2. The computer-implemented method of claim 1 , wherein controlling the first vehicle includes controlling movement of the first vehicle relative to the entry as defined by the start point of the entry and the end point of the entry to allow the traversal through the entry by the second vehicle.

3. The computer-implemented method of claim 2 , wherein controlling the first vehicle includes controlling the movement of the first vehicle to stop prior to the start point of the entry.

4. The computer-implemented method of claim 2 , wherein controlling the first vehicle includes transmitting a message about the movement of the first vehicle to the second vehicle using the vehicle communication network.

5. The computer-implemented method of claim 1 , wherein the start point of the entry and the end point of the entry are curb boundaries located to the right side of the first vehicle.

6. The computer-implemented method of claim 1 , wherein predicting the intent of the second vehicle is based on vehicle data about the second vehicle.

7. The computer-implemented method of claim 6 , wherein the second road is a driveway having an automatic garage door system located thereon, wherein the automatic garage door system communicates the vehicle data to the first vehicle using the vehicle communication network.

8. The computer-implemented method of claim 6 , wherein the first vehicle selectively obtains the vehicle data about the second vehicle.

9. The computer-implemented method of claim 8 , wherein if the first vehicle senses the second vehicle using sensors of the first vehicle, the first vehicle selectively obtains the vehicle data about the second vehicle using the sensors of the first vehicle, and wherein if the first vehicle does not sense the second vehicle using the sensors of the first vehicle, the first vehicle selectively obtains the vehicle data about the second vehicle from the second vehicle using the vehicle communication network.

10. A system for intersection control, comprising:
a sensor system to capture road data about boundary barriers along a first road in an environment surrounding a first vehicle traveling along the first road; and
a processor operatively connected for computer communication to the sensor system and a vehicle communication network, wherein the processor:
detects an uncontrolled intersection ahead of the first vehicle based on the road data, wherein the uncontrolled intersection includes an entry between the first road and a second road;
detects a start point of the entry and an end point of the entry based on the road data;
detects a controlled intersection in proximity to the uncontrolled intersection;
receives traffic data from the controlled intersection using the vehicle communication network;
predicts intent of a second vehicle to traverse through the entry by predicting traffic flow in proximity to the entry based on the traffic data; and
controls the first vehicle based on the traffic flow by controlling movement of the first vehicle relative to the entry to allow the traversal through the entry by the second vehicle.

11. The system of claim 10 , wherein the processor transmits a message to the second vehicle about the movement of the first vehicle.

12. The system for intersection control of claim 10 , wherein the processor controls the movement of the first vehicle relative to the entry as defined by the start point of the entry and the end point of the entry to allow the traversal through the entry by the second vehicle.

13. The system for intersection control of claim 12 , wherein the processor controls the movement of the first vehicle to stop prior to the start point of the entry.

14. The system for intersection control of claim 10 , wherein the start point of the entry and the end point of the entry are curb boundaries located to the right side of the first vehicle.

15. The system for intersection control of claim 10 , wherein the processor predicts the intent of the second vehicle to traverse through the entry based on vehicle data about the second vehicle, and the first vehicle selectively obtains the vehicle data about the second vehicle.

16. A non-transitory computer-readable storage medium including instructions that when executed by a processor, cause the processor to:
detect an uncontrolled intersection ahead of a first vehicle traveling along a first road, wherein the uncontrolled intersection includes an entry to a second road;
detect a start point of the entry and an end point of the entry with respect to the first vehicle using curb detection on the first road and the second road;
detect a controlled intersection in proximity to the uncontrolled intersection;
receive traffic data from the controlled intersection using a vehicle communication network;
predict intent of a second vehicle to traverse through the entry; and
control the first vehicle based on the traffic data to allow the traversal through the entry by the second vehicle.

17. The non-transitory computer-readable storage medium of claim 16 , wherein the processor controls movement of the first vehicle relative to the entry to allow the traversal through the entry by the second vehicle.

18. The non-transitory computer-readable storage medium of claim 16 , wherein the processor controls the first vehicle to stop prior to the start point of the entry to allow the traversal through the entry by the second vehicle.

19. The non-transitory computer-readable storage medium of claim 16 , wherein the processor transmits a message to the second vehicle about movement of the first vehicle.

20. The non-transitory computer-readable storage medium of claim 16 , wherein the start point of the entry and the end point of the entry are curb boundaries located to the right side of the first vehicle.
