Abstract

An object-detection system for an automated vehicle includes an object-detector, a receiver, and a controller. The object-detector detects detectable-objects proximate to a host-vehicle. The receiver receives an indication of an object-presence from other-transmitters proximate to the host-vehicle. The controller is in communication with the object-detector and the receiver. The controller is configured to operate the host-vehicle to avoid interference with a hidden-object when the hidden-object is not detected by the object-detector and the object-presence is indicated by at least two instances of the other-transmitters.

First claim

We claim:

1. An automated vehicle comprising:
an object-detector;
a receiver;
a controller in communication with the object-detector and the receiver, said controller configured to:
obtain, using the receiver, data from two or more transmitters;
determine, based on the data, a location of an object that is separate from the two or more transmitters;
determine, based on the data, a classification of the object;
determine, based at least in part on a comparison of the location with data related to a field-of-view of the object-detector and the classification of the object, whether the object is detected in the field-of-view of the object-detector; and
in accordance with the object being detected in the field of view, operate the automated vehicle to avoid interference with the object.

2. The automated vehicle in accordance with claim 1 , wherein the object is not detected by the object-detector when a line-of-sight to the object from the object-detector is obstructed.

3. The automated vehicle in accordance with claim 1 , wherein the automated vehicle is operated by the controller to avoid interference with the object when hosts of the two or more transmitters are detected by the object-detector.

4. The automated vehicle of claim 3 , wherein at least one of the hosts is another vehicle.

5. The automated vehicle of claim 3 , wherein at least one of the hosts is a traffic camera.

6. The automated vehicle of claim 1 , wherein the controller is further configured to:
determine, based on the data, a direction of travel of the object; and
determine, based at least in part on the location and direction of travel, whether the object is detected in the field-of-view.

7. The automated vehicle of claim 1 , wherein the object is another vehicle.

8. The automated vehicle of claim 1 , wherein the data from the two or more transmitters is redundant.

9. The automated vehicle of claim 1 , wherein the automated vehicle is located at an intersection, and in accordance with the object not being detected in the field of view of the object-detector, command the automated vehicle to wait a period of time before entering the intersection.

10. A method comprising:
obtaining, using a receiver of an automated vehicle, data from two or more transmitters, wherein the data from the two or more transmitters is redundant;
determining, based on the data, a location of an object;
determining, based on the data, a direction of travel of the object;
determining, based at least in part on the location and direction of travel, whether the object is detected in the field-of-view of an object-detector of the automated vehicle; and
in accordance with the object being detected in the field of view, operate the automated vehicle to avoid interference with the object.

11. The method of claim 10 , wherein the object is not detected by the object-detector when a line-of-sight to the object from the object-detector is obstructed.

12. The method of claim 10 , wherein the automated vehicle is operated by the controller to avoid interference with the object when hosts of the two or more transmitters are detected by the object-detector.

13. The method of claim 12 , wherein at least one of the hosts is another vehicle.

14. The method of claim 12 , wherein at least one of the hosts is a traffic camera.

15. The method of claim 10 , wherein the controller is further configured to:
determine, based on the data, a classification of the object; and
determine, based at least in part on the location and classification, whether the object is detected in the field-of-view.

16. The method of claim 10 , wherein the object is another vehicle.

17. The method of claim 10 , wherein the automated vehicle is located at an intersection, and in accordance with the object not being detected in the field of view of the object-detector, command the automated vehicle to wait a period of time before entering the intersection.
