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).

Claims

1. A computer-implemented method for alerting pedestrians of operational modes of nearby vehicles, comprising:

receiving, by an electronic device associated with a pedestrian, the electronic device including a user interface, an indication of a current operational mode transmitted by a nearby vehicle having one or more autonomous features,

wherein the current operational mode of the nearby vehicle is one of autonomous or manual;

receiving a minimum vehicle proximity through the user interface,

determining with the electronic device a proximity of the nearby vehicle,

triggering, by the electronic device associated with the pedestrian, an alert based on the current operational mode when the proximity of the nearby vehicle is equal to or less than the minimum vehicle proximity, the alert configured to notify the pedestrian of the current operational mode of the nearby vehicle,

receiving, by the electronic device associated with the pedestrian, an indication that the nearby vehicle has switched to another operational mode; and

ceasing the triggered alert based on the indication that the nearby vehicle has switched to the another operational mode.

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 ale by the pedestrian.

4. The computer-implemented method of claim 1, further comprising ceasing the triggered alert when the proximity of the nearby vehicle is greater than the minimum vehicle proximity.

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 a 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 the another operational mode.

9. A computer-implemented for alerting pedestrians of operational modes of vehicles, comprising:

detecting, by an electronic device associated with a vehicle having one or more autonomous features, a current operational mode of the vehicle, wherein the current operational mode is one of autonomous or manual;

triggering, by the electronic device, an alert based, at least in part, on the current operational mode, and conditions external to the electronic device and the vehicle, the external conditions including at least one of a time of day, a weather condition, a traffic condition, and a road condition,

wherein the alert is configured to be audible or visible to a nearby pedestrian and configured to notify the nearby pedestrian of the current operational mode of the vehicle;

detecting, by the electronic device, that the vehicle has switched to another operational mode; and

ceasing the triggered alert based on the detecting that the vehicle has switched to the another operational mode.

10. The computer-implemented method of claim 9, further comprising ceasing the triggered alert when the nearby pedestrian is no longer nearby.

11. The computer-implemented method of claim 10, wherein ceasing the triggered alert when the nearby pedestrian is no longer nearby further comprises:

detecting, by the electronic device, a location of the vehicle;

receiving, by the electronic device, a location of a second electronic device associated with the nearby pedestrian;

determining, by the electronic device, that the location of the second electronic device is at least a threshold distance from the location of the vehicle; and

in response to the determining, ceasing the triggered alert.

12. The computer-implemented method of claim 10, wherein ceasing the triggered alert when the nearby pedestrian is no longer nearby comprises:

receiving, by the electronic device, a short-range signal transmitted by a second electronic device associated with the nearby pedestrian; and

ceasing the triggered alert when the short-range signal is no longer received by the electronic device.

13. The computer-implemented method of claim 10, wherein ceasing the triggered alert when the nearby pedestrian is no longer nearby comprises:

receiving, by the electronic device, an indication of the nearby pedestrian detected by one or more sensors associated with the vehicle; and

ceasing the triggered alert when the indication of the nearby pedestrian is no longer received by the electronic device.

14. An electronic device configured to alert pedestrians of operational modes of nearby vehicles, comprising:

a transceiver configured to communicate data via at least one network connection;

a memory configured to store non-transitory computer executable instructions; and

a processor configured to interface with the transceiver and the memory, and configured to execute the non-transitory computer executable instructions to cause the processor to;
