Enabling content playing in autonomous vehicles of a transportation service

1. A method for enabling playing of content at an autonomous vehicle, the method comprising:

receiving, by a computing system having one or more processors, from a client computing device, a request to transport a user on a trip;

assigning, by the computing system, the autonomous vehicle to the trip;

determining, by the computing system, whether the user has enabled a content feature;

in response to determining that the user has enabled the content feature sending, by the computing system, a request for a device identifier to the assigned autonomous vehicle;

receiving, by the computing system, the device identifier generated at the assigned autonomous vehicle; and

sending, by the computing system, the device identifier to a content-enabling computing system including one or more processors in order to enable the user to play content from the client computing device at the assigned autonomous vehicle during the trip.

2. The method of claim 1 , further comprising, sending credentials for the user to the content-enabling computing system in order to enable the user to play content from the client computing device at the assigned autonomous vehicle during the trip.

3. The method of claim 2 , further comprising, receiving from an application of the client computing device, the credentials prior to receiving the request for the trip.

4. The method of claim 1 , further comprising:

receiving from an application of the client computing device a signal indicating that the user has enabled the content feature; and

saving the indication with account information of the user in storage, and wherein determining whether the user has enabled a content feature includes accessing the account information in the storage.

5. The method of claim 1 , further comprising receiving a signal indicating that the client computing device has been authenticated by one or more computing devices of the autonomous vehicle, and wherein the device identifier is sent in response to receiving the signal.

6. The method of claim 1 , further comprising receiving a signal indicating that a door of the autonomous vehicle has been opened, and wherein the device identifier is sent in response to receiving the signal.

7. The method of claim 1 , further comprising:

receiving a first signal indicating that the autonomous vehicle has reached a destination for the trip; and

in response to receiving the first signal, sending a second signal to the content-enabling computing system requesting that the device identifier be removed from an account of the user, thereby preventing the user from being able to play content at the assigned autonomous vehicle.

8. The method of claim 1 , further comprising, after sending the device identifier and during the trip:

receiving a new device identifier from the assigned autonomous vehicle; and

sending, by the computing system, the new device identifier to the content-enabling computing system in order to enable the user to play the content from the client computing device at the assigned autonomous vehicle during the trip.

9. The method of claim 1 , wherein the playing of content from the client computing device at the assigned autonomous vehicle during the trip is enabled without requiring a direct communication link between the client computing device and the assigned autonomous vehicle.

10. A method for enabling playing of content at an autonomous vehicle, the method comprising:

receiving, by a computing system having one or more processors, from a client computing device, a request to transport a user on a trip;

assigning, by the computing system, the autonomous vehicle to the trip;

determining, by the computing system, whether the user has enabled a content feature;

in response to determining that the user has enabled the content feature, identifying, by the computing system, a device identifier for the assigned autonomous vehicle; sending, by the computing system, the device identifier to the client computing device;

establishing, by the computing system, a communication link with the assigned autonomous vehicle; and

relaying, by the computing system, content received from the client computing device to a computing device of the assigned autonomous vehicle using the communication link.

11. The method of claim 10 , further comprising:

receiving from an application of the client computing device a signal indicating that the user has enabled the content feature; and

saving the indication with account information of the user in storage, and wherein determining whether the user has enabled a content feature includes accessing the account information in the storage.

12. The method of claim 10 , further comprising:

receiving a first signal indicating that the autonomous vehicle has reached a destination for the trip; and

in response to receiving the first signal, removing the device identifier from an account of the user, thereby preventing the user from being able to play content at the assigned autonomous vehicle.

13. The method of claim 10 , further comprising, after relaying the content and during the trip:

receiving a new device identifier from the assigned autonomous vehicle; and

sending, by the computing system, the new device identifier to the client computing device in order to enable the user to play the content from the client computing device at the assigned autonomous vehicle during the trip.

14. The method of claim 10 , wherein the playing of content from the client computing device at the assigned autonomous vehicle during the trip is enabled without requiring a direct communication link between the client computing device and the assigned autonomous vehicle.
