Abstract

An applique is mounted over one or both B-pillars of an autonomous vehicle and includes a display, speaker, touch input, and microphone. The applique may include a curved cover mounted over a printed circuit board (PCB) having LED arrays mounted thereto. A diffuser defines windows for the LED arrays and has a planar surface interfacing with the PCB and a curved surface interfacing with the curved cover. A controller of the vehicle detects proximity to a passenger to be picked up and displays the passenger's name at a first proximity, outputs a spoken message at a second, closer, proximity, and outputs a visible and audible prompt to enter an access code at a third proximity closer than the second proximity.

First claim

The invention claimed is:

1. An autonomous vehicle comprising:
a vehicle body having a B-pillar on a side of the vehicle;
an applique mounted to the vehicle body over the B-pillar and including a power supply coupled to an exterior of the vehicle body, a microphone, a speaker, a touch interface, and a display facing away from an interior of the autonomous vehicle in order to communicate with a passenger positioned external to and spaced from the autonomous vehicle such that the autonomous vehicle functions as an autonomous taxi, wherein the power supply is disposed between the exterior of the vehicle body and the display; and
a controller coupled to the applique and programmed to:
output messages to the passenger using the display and speaker;
receive inputs from the passenger using the microphone and touch interface; and
unlock one or more doors of the autonomous vehicle and output a visible and/or audible prompt to the passenger to enter the vehicle.

2. The autonomous vehicle of claim 1 , wherein the applique is mounted to one of the B-pillar of the vehicle body and a door frame positioned over the B-pillar when closed.

3. The autonomous vehicle of claim 1 , wherein the applique has a curved outer surface.

4. The autonomous vehicle of claim 3 , wherein the applique comprises:
a curved cover;
a printed circuit board (PCB), the touch interface and display being mounted to the PCB, the touch interface being positioned external with respect to the vehicle body;
and a diffuser having a flat surface facing the PCB and a curved surface opposite the flat surface facing the curved cover, the cover having a curved inner surface facing the curved surface.

5. The autonomous vehicle of claim 4 , wherein the display comprises a plurality of display clusters mounted to the PCB; and
wherein the diffuser comprises a plurality of openings positioned over the plurality of display clusters.

6. The autonomous vehicle of claim 5 , wherein the plurality of openings are filled with a solid transparent material.

7. The autonomous vehicle of claim 5 , wherein the plurality of display clusters are each an array of light emitting diodes (LED) each disposed external with respect to said vehicle body.

8. The autonomous vehicle of claim 1 , wherein the controller is further programmed to:
detect that the passenger is within a first proximity threshold to the autonomous vehicle;
and in response to detecting that the passenger is within the first proximity threshold to the autonomous vehicle, display an identifier associated with the passenger on the display without outputting an audio signal using the speaker.

9. The autonomous vehicle of claim 8 , wherein the controller is further programmed to:
detect that the passenger is within a second proximity threshold to the autonomous vehicle;
in response to detecting that the passenger is within the second proximity threshold to the vehicle, display the identifier on the display and output an audio rendition of the passenger's name using the speaker.

10. The autonomous vehicle of claim 9 , wherein the controller is further programmed to:
detect that the passenger is within a third proximity threshold to the autonomous vehicle;
in response to detecting that the passenger is within the third proximity threshold to the autonomous vehicle, display a request for a code on the display and output an audio rendition of a request for the code using the speaker;
receive an input from the passenger through one of the microphone and the touch interface;
and when the input matches the code, unlock the one or more doors of the vehicle.

11. The autonomous vehicle of claim 10 , wherein the third proximity threshold is less than or equal to 0.5 meter.

12. The autonomous vehicle of claim 10 , wherein the controller is further programmed to, when the input matches the code:
detect opening and closing of the door of the autonomous vehicle;
wait for a delay period; and
autonomously navigating to a destination after waiting for the delay period.

13. The autonomous vehicle of claim 10 , wherein the controller is further programmed to evaluate proximity of the passenger to the autonomous vehicle by evaluating global positioning system (GPS) coordinates received from a mobile device of the passenger.

14. The autonomous vehicle of claim 13 , wherein the controller is further programmed to evaluate whether the passenger is within the third proximity threshold to the autonomous vehicle by evaluating both of global positioning system (GPS) coordinates received from the mobile device of the passenger and an output of a proximity sensor.

15. The autonomous vehicle of claim 14 , wherein the proximity sensor is an infrared sensor.

16. The autonomous vehicle of claim 13 , further comprising one or more external sensors including at least one of a camera, a LIDAR (light detection and ranging) sensor, and a RADAR (radio detection and ranging) sensor;
wherein the controller is further programmed to:
when outputs of the one or more external sensors indicate a hazard to the passenger, output an audible warning using one of the speaker, a piezo-electric buzzer, and the display.

17. A method comprising:
detecting, by an autonomous vehicle, that a passenger is within a first proximity threshold to the autonomous vehicle;
in response to detecting that the passenger is within the first proximity threshold to the autonomous vehicle, display the passenger's name on a display mounted over the B-pillar on a side of the autonomous vehicle and without outputting an audio rendition of the passenger's name using a speaker, wherein the display is powered by a power supply coupled to an exterior of a body of the autonomous vehicle, wherein the display faces away from an interior of the autonomous vehicle in order to communicate with the passenger when positioned external to and spaced from the autonomous vehicle such that the autonomous vehicle functions as an autonomous taxi, and wherein the power supply is disposed between the exterior of the vehicle body and the display;
detecting, by the autonomous vehicle, that the passenger is within a second proximity threshold to the autonomous vehicle; and
in response to detecting that the passenger is within the second proximity threshold to the autonomous vehicle, displaying, by the autonomous vehicle, the passenger's name on the display and output the audio rendition of the passenger's name using the speaker;
detecting that the passenger is within a third proximity threshold to the autonomous vehicle;
in response to detecting that the passenger is within the third proximity threshold to the autonomous vehicle, displaying, by the autonomous vehicle, a request for a code on the display and outputting an audio rendition of a request for the code using the speaker;
receiving, by the autonomous vehicle, an input from the passenger through one of a microphone and a touch interface; and
when the input matches the code, unlocking, by the autonomous vehicle, a door of the autonomous vehicle and outputting a visible and/or audible prompt to the passenger to enter the vehicle.

18. The method of claim 17 , wherein the third proximity threshold is less than or equal to 0.5 meter.

19. The method of claim 17 , further comprising:
detecting, by the autonomous vehicle, opening and closing of the door of the autonomous vehicle;
waiting, by the autonomous vehicle, for a delay period; and
autonomously navigating, by the autonomous vehicle, to a destination after waiting for the delay period.
