Abstract

A system and method are provided and include a controller that controls a door lock actuator system of an autonomous vehicle. The controller is configured to receive a request for transportation from a server in communication with a smartphone. The request for transportation includes a pickup location and a unique identifier. The controller is configured to store the unique identifier received from the server as a stored unique identifier, to communicate directly with the smartphone, to receive a smartphone unique identifier from the smartphone, to compare the smartphone unique identifier with the stored unique identifier, and to control the door lock actuator system to unlock and/or open at least one door of the autonomous vehicle when the smartphone unique identifier matches the stored unique identifier.

Claims

1. A system comprising:

a controller that controls a door lock actuator system of an autonomous vehicle, the controller being configured to (i) receive a request for transportation from a server, the request for transportation including a pickup location and a first smartphone unique identifier,

(ii) to store the first smartphone unique identifier received from the server, (iii) to search for smartphones in a wireless communication range of the autonomous vehicle in response to the autonomous vehicle arriving at the pickup location, (iv) to receive a second smartphone unique identifier from a smartphone at the pickup location via a direct wireless communication link with the smartphone, (v) to compare the second smartphone unique identifier with the stored first smartphone unique identifier, and (vi) to control the door lock actuator system to unlock and/or open at least one door of the autonomous vehicle in response to the second smartphone unique identifier matching the stored first smartphone unique identifier.

2. The system of claim 1, wherein the controller continues to search for additional smartphones when the second smartphone unique identifier does not match the stored first smartphone unique identifier.

3. The system of claim 1, wherein the controller communicates with the smartphone using a wireless personal area network.

4. The system of claim 1, wherein the controller receives a communication packet from the smartphone that includes the second smartphone unique identifier.

5. The system of claim 1, wherein the controller establishes communication with the smartphone and requests that the smartphone provide the second smartphone unique identifier.

6. The system of claim 1, wherein the controller controls the door lock actuator system to unlock at least one door of the autonomous vehicle when the second smartphone unique identifier matches the stored first smartphone unique identifier.

7. The system of claim 1, wherein the controller controls the door lock actuator system to open at least one door of the autonomous vehicle when the second smartphone unique identifier matches the stored first smartphone unique identifier.

8. A method comprising:

receiving, with a controller of an autonomous vehicle, a request for transportation from a server, the request for transportation including a pickup location and a first smartphone unique identifier;

storing, with the controller, the first smartphone unique identifier received from the server in a memory accessible to the controller;

searching, with the controller, for smartphones in a wireless communication range of the autonomous vehicle in response to the autonomous vehicle arriving at the pickup location;

receiving, with the controller, a second smartphone unique identifier from a smartphone at the pickup location via a direct wireless communication link with the smartphone;

comparing, with the controller, the second smartphone unique identifier with the stored first smartphone unique identifier; and

controlling, with the controller, a door lock actuator system to unlock and/or open at least one door of the autonomous vehicle in response to the second smartphone unique identifier matching the stored first smartphone unique identifier.

9. The method of claim 8, further comprising continuing to search, with the controller, for additional smartphones when the second smartphone unique identifier does not match the stored first smartphone unique identifier.

10. The method of claim 8, wherein the controller communicates with the smartphone using a wireless personal area network.

11. The method of claim 8, wherein the controller receives a communication packet from the smartphone that includes the second smartphone unique identifier.

12. The method of claim 8, wherein the controller establishes communication with the smartphone and requests that the smartphone provide the second smartphone unique identifier.

13. The method of claim 8, wherein the controller controls the door lock actuator system to unlock at least one door of the autonomous vehicle when the second smartphone unique identifier matches the stored first smartphone unique identifier.

14. The method of claim 8, wherein the controller controls the door lock actuator system to open at least one door of the autonomous vehicle when the second smartphone unique identifier matches the stored first smartphone unique identifier.

15. A system comprising:

an autonomous vehicle;

a door lock actuator system that controls locking and unlocking of at least one door of the autonomous vehicle; and

a controller configured to (i) receive a request for transportation from a server, the request for transportation including a pickup location and a first smartphone unique identifier received by the server from a smartphone, (ii) to store the first smartphone unique identifier received from the server as a stored smartphone unique identifier, (iii) to search for the smartphone in a wireless communication range of the autonomous vehicle in response to the autonomous vehicle arriving at the pickup location, (iv) to receive the first smartphone unique identifier from the smartphone at the pickup location via at least one direct wireless communication link with the smartphone, (v) to compare the first smartphone unique identifier with the stored smartphone unique identifier, and (vi) to control the door lock actuator system to unlock and/or open at least one door of the autonomous vehicle in response to the first smartphone unique identifier matching the stored smartphone unique identifier.

16. The system of claim 15, wherein the controller is configured to communicate with the smartphone using a wireless personal area network.

17. The system of claim 15, wherein the controller is configured to receive a communication packet from the smartphone that includes the first smartphone unique identifier.

18. The system of claim 15, wherein the controller is configured to establish communication with the smartphone and then request that the smartphone provide the first smartphone unique identifier.

19. The system of claim 15, wherein the controller is configured to control the door lock actuator system to unlock at least one door of the autonomous vehicle in response to the first smartphone unique identifier matching the stored smartphone unique identifier.

20. The system of claim 15, wherein the controller is configured to control the door lock actuator system to open at least one door of the autonomous vehicle in response to the first smartphone unique identifier matching the stored smartphone unique identifier.
