Abstract

Disclosed are methods and devices for transitioning a mixed-mode autonomous vehicle from a human driven mode to an autonomously driven mode. Transitioning may include stopping a vehicle on a predefined landing strip and detecting a reference indicator. Based on the reference indicator, the vehicle may be able to know its exact position. Additionally, the vehicle may use the reference indictor to obtain an autonomous vehicle instruction via a URL. After the vehicle knows its precise location and has an autonomous vehicle instruction, it can operate in autonomous mode.

First claim

What is claimed is:

1. A method comprising:
wirelessly capturing data from a reference indicator via a mobile device, wherein the reference indicator comprises one of an optical code or a radio link, and wherein the reference indicator is mounted within a line of sight of a landing strip; and
wirelessly requesting an autonomous vehicle, via the mobile device, to a location of the mobile device based on the captured data.

2. The method of claim 1 , wherein the reference indicator comprises an internet address.

3. The method of claim 1 , wherein the reference indicator comprises global coordinate information.

4. The method of claim 1 , wherein the data from the reference indicator is cryptographically signed.

5. The method of claim 1 , wherein capturing data from the reference indicator comprises capturing an image of the reference indicator.

6. The method of claim 1 , wherein capturing data from the reference indicator comprises wirelessly receiving the data via a radio.

7. An article of manufacture including a tangible non-transitory computer-readable storage medium having stored thereon computer-readable instructions that, upon execution by a computing device, cause the computing device to perform functions comprising:
wirelessly capturing data from a reference indicator, wherein the reference indicator comprises one of an optical code or a radio link, and wherein the reference indicator is mounted within a line of sight of a landing strip; and
wirelessly requesting an autonomous vehicle to a location of the computing device based on the captured data.

8. The article of manufacture of claim 7 , wherein the reference indicator comprises an internet address.

9. The article of manufacture of claim 7 , wherein the reference indicator comprises global coordinate information.

10. The article of manufacture of claim 7 , wherein the data from the reference indicator is cryptographically signed.

11. The article of manufacture of claim 7 , wherein capturing data from the reference indicator comprises capturing an image of the reference indicator.

12. The article of manufacture of claim 7 , wherein capturing data from the reference indicator comprises wirelessly receiving the data via a radio.

13. A method for requesting an autonomous vehicle to a location comprising:
capturing image data of a reference indicator via a mobile device, wherein the reference indicator is associated with a landing strip; and
requesting an autonomous vehicle to a location of the computing device, via the mobile device, based on the captured image data, wherein the reference indicator is mounted within a line of sight of the landing strip and comprises global coordinate information.

14. The method of claim 13 , wherein the reference indicator comprises an internet address.

15. The method of claim 13 , wherein the data from the reference indicator is cryptographically signed.
