Abstract

A method for operating an autonomous vehicle that includes guiding the autonomous vehicle along a planned path of travel. The autonomous vehicle may be brought to a stop along the planned path of travel, during which an operator of the vehicle may offer to allow another vehicle and/or person to pass in front of the stopped autonomous vehicle. The vehicle to which the offer is directed may transmit an acceptance signal in response to the offer signal indicating acceptance of the offer. The acceptance signal may be received by the autonomous vehicle, which may modify its planned path of travel in response to receiving the acceptance signal.

Claims

1. A method in a computing device for operating an autonomous vehicle, the method comprising:

when coming to a stopped condition of a planned path of travel, detecting by at least one sensor of the autonomous vehicle;

an offer signal of an autonomous vehicle operator, wherein the offer signal operates to indicate an offer for allowing a prospective obstacle to pass in front of the stopped autonomous vehicle;

receiving, via the computing device, an acceptance signal from the prospective obstacle responsive to the offer signal, wherein the acceptance signal operates to indicate acceptance of the offer signal; and

modifying, by the computing device, the planned path of travel of the autonomous vehicle in response to receiving the acceptance signal.

2. The method of claim 1, wherein the offer signal comprises at least one of:

a physical gesture performed by the autonomous vehicle operator; and

a verbal communication uttered the autonomous vehicle operator.

3. The method of claim 2, wherein the at least one sensor comprises at least one of:

an imaging device; and

an audio device.

4. The method of claim 3, wherein the imaging and audio devices are coupled with the prospective obstacle.

5. The method of claim 1 further comprising:

employing a notification interface that includes at least one of a tactile input device and an audio input device for initiating transmission of the acceptance signal.

6. The method of claim 5, wherein the notification interface being configured to be transported on a person.

7. The method of claim 1 further comprising:

receiving a location signal from the prospective obstacle in connection with the acceptance signal, the location signal indicating a location of the prospective obstacle.

8. The method of claim 1, wherein the prospective obstacle comprises at least one of:

a vehicle;

a pedestrian; and

a bicyclist.

9. The method of claim 1 further comprising:

receiving the acceptance signal at a second vehicle; and

modifying a path of travel of the second vehicle in response to receiving the acceptance signal.

10. The method of claim 1 further comprising:

transmitting a warning signal to an operator of a second vehicle for providing notice that the prospective obstacle may be crossing a second path of travel of the second vehicle.

11. The method of claim 1 further comprising:

maintaining the autonomous vehicle in the stopped condition in response to receipt of the acceptance signal.

12. The method of claim 1 further comprising tracking a location of the prospective obstacle in response to receiving the acceptance signal.

13. A method in a computing device for operating an autonomous vehicle, the method comprising:

when coming to a stopped condition along a planned path of travel, detecting by a sensor of the autonomous vehicle;

an offer signal from an operator of the autonomous vehicle to indicate an offer for allowing a prospective obstacle to pass in front of the stopped autonomous vehicle; and

wherein, in response to the detecting the offer signal;

transmitting a notification signal for indicating the autonomous vehicle has stopped for the prospective obstacle; and

modifying, by the computing device, the planned path of travel of the autonomous vehicle.

14. The method of claim 13, wherein the offer signal comprises at least one of:

a physical gesture performed by the operator of the autonomous vehicle; and

a verbal communication uttered by the operator of the autonomous vehicle.

15. The method of claim 14, wherein the sensor comprises at least one of:

an imaging device; and

an audio device.

16. The method of claim 13, wherein the sensor comprises a tactile input device operable to sense a tactile input being applied to the autonomous vehicle.

17. The method of claim 13 further comprising:

in response to the detecting the offer signal, transmitting a location signal with the notification signal, the location signal for indicating a location of the prospective obstacle.

18. The method of claim 13, wherein the prospective obstacle comprises at least one of:

a vehicle; and

a pedestrian.

19. The method of claim 13 further comprising:

maintaining the autonomous vehicle in the stopped condition in response to receipt of an acceptance signal.

20. The method of claim 13 further comprising tracking a location of the prospective obstacle in response to receipt of an acceptance signal.
