Abstract

A system and method are provided and include a light source projector mounted on a subject vehicle, a controller that controls the light source projector to project a bounding box on a roadway upon which the subject vehicle is traveling in a destination lane of a lane change of the subject vehicle; and a sensor that detects a response image projected by a secondary vehicle on the roadway in the adjacent lane, the response image indicating either agreement or disagreement with the lane change of the subject vehicle. The controller generates an alert in the subject vehicle based on the detected response.

First claim

What is claimed is:

1. A system comprising:
at least one light source projector mounted on a subject vehicle;
a controller that controls the at least one light source projector to project a bounding box on a roadway upon which the subject vehicle is traveling in a destination lane of a lane change of the subject vehicle, the bounding box being projected entirely within the destination lane and ahead of a secondary vehicle traveling on the roadway in the destination lane; and
a sensor that detects a response image projected by the secondary vehicle on the roadway in the destination lane, the response image indicating agreement with the lane change of the subject vehicle;
wherein the controller generates an alert in the subject vehicle based on the detected response image.

2. The system of claim 1 , further comprising at least one additional light source projector mounted on the subject vehicle, wherein the controller controls the at least one light source projector to project a response image projected by the subject vehicle, the response image indicating either agreement or disagreement with a lane change of another vehicle.

3. The system of claim 1 , further comprising at least one positional actuator associated with each light source projector of the at least one light source projector, wherein the controller controls the at least one light source projector to project the bounding box on the roadway by controlling the at least one positional actuator associated with each light source projector.

4. The system of claim 1 , wherein the sensor includes an image sensor.

5. The system of claim 1 , further comprising at least one additional sensor that detects a position of other vehicles traveling on the roadway, wherein the controller detects whether another vehicle traveling on the roadway has entered the bounding box within a predetermined time period after initiating projection of the bounding box and generates another alert in the subject vehicle based on whether another vehicle traveling on the roadway has entered the bounding box.

6. The system of claim 5 , wherein the at least one additional sensor includes at least one of an image sensor, a radar sensor, a lidar sensor, and an ultrasonic sensor.

7. The system of claim 5 , wherein the at least one additional sensor is configured to detect a secondary vehicle traveling two lanes over from the subject vehicle and wherein the controller controls the at least one light source projector to project a graphic image within the bounding box in response to detecting the secondary vehicle traveling two lanes over from the subject vehicle.

8. The system of claim 1 , wherein the sensor detects an additional response image projected by the secondary vehicle on the roadway in the destination lane, the additional response image indicating disagreement with the lane change of the subject vehicle.

9. The system of claim 1 , wherein the sensor detects the response image projected by the secondary vehicle within the bounding box projected by the subject vehicle.

10. A method comprising:
controlling, with a controller, at least one light source projector mounted on a subject vehicle to project a bounding box on a roadway upon which the subject vehicle is traveling in a destination lane of a lane change of the subject vehicle, the bounding box being projected entirely within the destination lane and ahead of a secondary vehicle traveling on the roadway in the destination lane;
detecting, with a sensor, a response image projected by the secondary vehicle on the roadway in the destination lane, the response image indicating agreement with the lane change of the subject vehicle; and
generating, with the controller, an alert in the subject vehicle based on the detected response image.

11. The method of claim 10 , further comprising controlling, with the controller, at least one additional light source projector mounted on the subject vehicle to project a response image projected by the subject vehicle, the response image indicating either agreement or disagreement with a lane change of another vehicle.

12. The method of claim 10 , further comprising controlling, with the controller, at least one positional actuator associated with each light source projector of the at least one light source projector to project the bounding box on the roadway.

13. The method of claim 10 , wherein the sensor includes an image sensor.

14. The method of claim 10 , further comprising detecting, with at least one additional sensor that detects a position of other vehicles traveling on the roadway, wherein the controller detects whether another vehicle traveling on the roadway has entered the bounding box within a predetermined time period after initiating projection of the bounding box and generates another alert in the subject vehicle based on whether another vehicle traveling on the roadway has entered the bounding box.

15. The method of claim 14 , wherein the at least one additional sensor includes at least one of an image sensor, a radar sensor, a lidar sensor, and an ultrasonic sensor.

16. The method of claim 14 , wherein the at least one additional sensor is configured to detect a secondary vehicle traveling two lanes over from the subject vehicle, the method further comprising controlling, with the controller, the at least one light source projector to project a graphic image within the bounding box in response to detecting the secondary vehicle traveling two lanes over from the subject vehicle.

17. A system comprising:
at least one light source projector mounted on an autonomous vehicle;
a controller that controls the at least one light source projector to project a bounding box on a roadway upon which the autonomous vehicle is traveling in a destination lane of a lane change of the autonomous vehicle, the bounding box being projected entirely within the destination lane and ahead of a secondary vehicle traveling on the roadway in the destination lane; and
a sensor that detects a response image projected by the secondary vehicle on the roadway in the destination lane, the response image indicating agreement with the lane change of the autonomous vehicle;
wherein the controller controls the autonomous vehicle to change lanes into the destination lane in response to the response image indicating agreement.

18. The system of claim 17 , further comprising at least one additional light source projector mounted on the autonomous vehicle, wherein the controller controls the at least one light source projector to project a response image projected by the autonomous vehicle, the response image indicating either agreement or disagreement with a lane change of another vehicle.

19. The system of claim 17 , further comprising at least one positional actuator associated with each light source projector of the at least one light source projector, wherein the controller controls the at least one light source projector to project the bounding box on the roadway by controlling the at least one positional actuator associated with each light source projector.

20. The system of claim 17 , wherein the sensor includes an image sensor.

21. The system of claim 17 , further comprising at least one additional sensor that detects a position of other vehicles traveling on the roadway, wherein the controller detects whether another vehicle traveling on the roadway has entered the bounding box within a predetermined time period after initiating projection of the bounding box and controls the autonomous vehicle to ch
