Abstract

An alert may be triggered to notify a pedestrian of the current operational mode of a nearby vehicle. For instance, a vehicle may operate in an autonomous or manual mode, and may occasionally switch from one mode to the other. A pedestrian who may be unaware of the current operational mode of a nearby vehicle may notice the alert and proceed accordingly. In one embodiment, an indication of the current operational mode of the nearby vehicle may be transmitted to an electronic device associated with the pedestrian. The device may generate a notification to the pedestrian based on the current operational mode. In an additional or alternative embodiment, the alert may be transmitted by the vehicle externally to be visible or audible to the pedestrian. In some embodiments, the alert may be triggered only for particular operational modes (e.g., only for autonomous or only for manual).

First claim

What is claimed:

1. A computer-implemented method, comprising:
receiving, by an electronic device associated with a pedestrian, an indication of a current operational mode transmitted by a nearby vehicle wherein the current operational mode of the nearby vehicle is one of autonomous, semi-autonomous, or manual; and
triggering, by the electronic device associated with the pedestrian, an alert based, at least in part, on a prevalence of vehicles in an area surrounding a current location of the electronic device, wherein statistical data indicating the prevalence of vehicles in the area surrounding the current location of the electronic device is retrieved from a database, the alert configured to notify a pedestrian of the current operational mode of the nearby vehicle.

2. The computer-implemented method of claim 1 , wherein the triggered alert is one or more of a sound, vibration, light, or display of the electronic device.

3. The computer-implemented method of claim 1 , further comprising:
ceasing the triggered alert upon receiving an indication of a dismissal of the triggered alert by the pedestrian.

4. The computer-implemented method of claim 1 , further comprising ceasing the triggered alert when the nearby vehicle is no longer nearby.

5. The computer-implemented method of claim 4 , wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
receiving, by the electronic device, a location of the nearby vehicle;
determining, by the electronic device, that the location of the nearby vehicle is at least a threshold distance from the current location of the electronic device; and
in response to the determining, ceasing the triggered alert.

6. The computer-implemented method of claim 4 , wherein the indication is a short-range signal, and wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
ceasing the triggered alert when the short-range signal is no longer received by the electronic device.

7. The computer-implemented method of claim 1 , further comprising:
receiving, by the electronic device associated with the pedestrian, an indication of a preference to trigger the alert based on the current operational mode.

8. The computer-implemented method of claim 1 , further comprising:
triggering a second alert when the current operational mode of the vehicle switches to another operational mode.

9. A tangible, non-transitory computer-readable medium storing executable instructions that, when executed by at least one processor, cause the at least one processor to:
receive an indication of a current operational mode transmitted by a nearby vehicle, wherein the current operational mode of the nearby vehicle is one of autonomous, semi-autonomous, or manual; and
trigger an alert, by an electronic device associated with a pedestrian, based, at least in part, on a prevalence of vehicles in an area surrounding a current location of the electronic device, wherein statistical data indicating the prevalence of vehicles in the area surrounding the current location of the electronic device is retrieved from a database, the alert configured to notify the pedestrian of the current operational mode of the nearby vehicle.

10. The tangible, non-transitory computer-readable medium of claim 9 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to cease the triggered alert when the nearby vehicle is no longer nearby.

11. The tangible, non-transitory computer-readable medium of claim 10 , wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
receiving a location of the nearby vehicle;
determining that the location of the nearby vehicle is at least a threshold distance from the current location of the electronic device; and
in response to the determining, ceasing the triggered alert.

12. The tangible, non-transitory computer-readable medium of claim 10 , wherein the indication is a short-range signal, and wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
ceasing the triggered alert when the short-range signal is no longer received by the electronic device.

13. The tangible, non-transitory computer-readable medium of claim 9 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to receive an indication of a preference to trigger the alert based on the current operational mode.

14. An electronic device, comprising:
a memory configured to store non-transitory computer executable instructions; and
at least one processor configured to execute the non-transitory computer executable instructions to cause the at least one processor to:
receive an indication of a current operational mode transmitted by a nearby vehicle, wherein the current operational mode of the nearby vehicle is one of autonomous, semi-autonomous, or manual; and
trigger an alert based, at least in part, on a prevalence of vehicles in an area surrounding a current location of the electronic device, wherein statistical data indicating the prevalence of vehicles in the area surrounding the current location of the electronic device is retrieved from a database, the alert configured to notify a pedestrian associated with the electronic device of the current operational mode of the nearby vehicle.

15. The electronic device of claim 14 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to cease the triggered alert when the nearby vehicle is no longer nearby.

16. The electronic device of claim 15 , wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
receiving a location of the nearby vehicle;
determining that the location of the nearby vehicle is at least a threshold distance from the current location of the electronic device; and
in response to the determining, ceasing the triggered alert.

17. The electronic device of claim 15 , wherein the indication is a short-range signal, and wherein ceasing the triggered alert when the nearby vehicle is no longer nearby comprises:
ceasing the triggered alert when the short-range signal is no longer received by the electronic device.

18. The electronic device of claim 14 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to receive an indication of a preference to trigger the alert based on the current operational mode.

19. The electronic device of claim 14 , wherein the triggered alert is one or more of a sound, vibration, light, or display of the electronic device.

20. The electronic device of claim 14 , wherein the computer executable instructions further cause the at least one processor to:
cease the triggered alert upon receiving an indication of a dismissal of the triggered alert by the pedestrian.
