Abstract

A system to provide alerts to guide visually-impaired passengers to a vehicle is disclosed. The system includes a passenger identification module that is configured to identify a passenger based upon sensor data received at an autonomous vehicle and a passenger proximity module that is configured to determine a distance between the passenger and the autonomous vehicle. The system also includes an alert module that is configured to generate an alert having an alert characteristic corresponding to the distance.

Claims

1. A system comprising:

a passenger identification module that is configured to identify a passenger based upon sensor data received at an autonomous vehicle;

a passenger proximity module that is configured to determine a distance between the passenger and the autonomous vehicle; and

an alert module that is configured to generate an alert having an alert characteristic indicative of the distance and a vehicle door to enter based on an occupancy of the autonomous vehicle.

2. The system as recited in claim 1, further comprising a passenger guidance module that is configured to determine whether the distance is greater than a predetermined distance threshold and selects the alert characteristic when the distance is greater than the predetermined distance threshold and selects another alert characteristic when the distance is less than the predetermined distance threshold.

3. The system as recited in claim 1, further comprising a plurality of sensors configured to generate sensor data indicative of an environment surrounding the autonomous vehicle.

4. The system as recited in claim 3, wherein the plurality of sensors comprise at least one of a radar device, a light detection and ranging (LIDAR) device, an optical camera, a thermal camera, an ultrasonic sensor, a pressure sensor, an ultra-wide band (UWB) sensor, and a global positioning system (GPS) receiver.

5. The system as recited in claim 1, wherein the alert module is configured to transmit the alert to a mobile electronic device associated with the passenger.

6. The system as recited in claim 5, wherein the mobile electronic device generates at least one of a haptic feedback and an audible alert based upon the alert.

7. The system as recited in claim 1, wherein the alert module is configured to generate the alert at at least one of a haptic device and an audio device disposed proximate to a vehicle handle of the autonomous vehicle.

8. The system as recited in claim 7, wherein the haptic device generates haptic feedback based upon the alert and the audio device generates an audible alert based upon the alert.

9. The system as recited in claim 7, wherein the alert module is configured to generate the alert at the at least one of the haptic device and the audio device based upon an occupancy of the autonomous vehicle.

10. The system as recited in claim 1, further comprising a door management module that is configured to unlock a door handle when the distance is less than a predetermined distance threshold.

11. A method, comprising:

identifying a passenger based upon sensor data received at an autonomous vehicle;

determining a distance between the passenger and the autonomous vehicle; and

generating an alert having an alert characteristic indicative of the distance and a vehicle door to enter based on an occupancy of the autonomous vehicle.

12. The method as recited in claim 11, further comprising determining whether the distance is greater than a predetermined distance threshold and selecting the alert characteristic when the distance is greater than the predetermined distance threshold and selecting another alert characteristic when the distance is less than the predetermined distance threshold.

13. The method as recited in claim 11, wherein receiving the sensor data further comprises receiving the sensor data from a plurality of sensors configured to generate sensor data indicative of an environment surrounding the autonomous vehicle.

14. The method as recited in claim 13, wherein the plurality of sensors comprise at least one of a radar device, a light detection and ranging (LIDAR) device, an optical camera, a thermal camera, an ultrasonic sensor, a pressure sensor, an ultra-wide band (UWB) sensor, and a global positioning system (GPS) receiver.

15. The method as recited in claim 11, further comprising transmitting the alert to a mobile electronic device associated with the passenger.

16. The method as recited in claim 15, wherein the mobile electronic device generates at least one of a haptic feedback and an audible alert based upon the alert.

17. The method as recited in claim 11, further comprising generating the alert at at least one of a haptic device and an audio device disposed proximate to a vehicle handle of the autonomous vehicle based upon an occupancy of the autonomous vehicle.

18. The method as recited in claim 17, wherein the haptic device generates haptic feedback based upon the alert and the audio device generates an audible alert based upon the alert.

19. The method as recited in claim 11, wherein the alert characteristic comprises at least one of a frequency characteristic, a pulse duration characteristic, a pulse separation characteristic, and an audible command.

20. A system comprising:

a passenger identification module that is configured to identify a passenger based upon sensor data received at an autonomous vehicle;

a passenger proximity module that is configured to determine a distance between the passenger and the autonomous vehicle; and

an alert module that is configured to generate an alert having an alert characteristic corresponding to the distance,

wherein the alert module is configured to generate the alert at at least one of a haptic device and an audio device disposed proximate to a vehicle handle of the autonomous vehicle based upon an occupancy of the autonomous vehicle.
