Abstract

A computer-implemented method may include subscribing to a first topic tree topic associated with an installed vehicle software component version; identifying a desired software component version based on a published notification retrieved from the first topic; and when the desired version and the installed version differ, updating a software component using a software update retrieved from a second topic tree topic associated with software updates to the installed version.

Claims

1. A computer-implemented method comprising:

subscribing to a first topic tree topic associated with an installed vehicle software component version;

identifying a desired software component version based on a published notification retrieved from the first topic; and

when the desired version and the installed version differ, updating a software component using a software update retrieved from a second topic tree topic associated with software updates to the installed version.

2. The method of claim 1, further comprising:

unsubscribing from the first topic tree topic; and

subscribing to a third topic tree topic associated with a version of the software component after application of the software update.

3. The method of claim 1, further comprising subscribing to the second topic of the topic tree upon determining that the desired version and the installed version differ.

4. The method of claim 1, further comprising unsubscribing from the second topic of the topic tree upon successful updating of the software component using the software update.

5. The method of claim 1, further comprising ignoring a software update published to the second topic of the topic tree until receiving the notification of the desired version in the topic.

6. The method of claim 1, wherein the published notification in the topic includes a configuration file, and further comprising determining the desired version according to a version level of the software with which the configuration file is compatible.

7. The method of claim 6, further comprising identifying the version level of the software with which the configuration file is compatible according to a version indication included in the configuration file.

8. A vehicle, comprising:

a vehicle-based computing system configured to;

subscribe to a first topic tree topic associated with an installed vehicle software component version;

identify a desired software component version based on a published notification retrieved from the first topic; and

when the desired version and the installed version differ, update a software component using a software update retrieved from a second topic tree topic associated with software updates to the installed version.

9. The vehicle of claim 8, wherein the vehicle-based computing system is further configured to:

unsubscribe from the first topic tree topic; and

subscribe to a third topic tree topic associated with a version of the software component after application of the software update.

10. The vehicle of claim 8, wherein the vehicle-based computing system is further configured to subscribe to the second topic of the topic tree upon determining that the desired version and the installed version differ.

11. The vehicle of claim 8, wherein the vehicle-based computing system is further configured to unsubscribe from the second topic of the topic tree upon successful updating of the software component using the software update.

12. The vehicle of claim 8, wherein the vehicle-based computing system is further configured to ignore a software update published to the second topic of the topic tree until receiving the notification of the desired version in the topic.

13. The vehicle of claim 8, wherein the published notification in the topic includes a configuration file, and wherein the vehicle-based computing system is further configured to determine the desired version according to a version level of the software with which the configuration file is compatible.

14. The vehicle of claim 13, wherein the vehicle-based computing system is further configured to identify the version level of the software with which the configuration file is compatible according to a version indication included in the configuration file.

15. A non-transitory computer readable storage medium, storing instructions that, when executed by a processor, configure the processor to:

subscribe to a first topic tree topic associated with an installed vehicle software component version;

identify a desired software component version based on a published notification retrieved from the first topic; and

when the desired version and the installed version differ, update a software component using a software update retrieved from a second topic tree topic associated with software updates to the installed version.

16. The computer readable storage medium of claim 15 additionally storing instructions to configure the processor to:

unsubscribe from the first topic tree topic; and

subscribe to a third topic tree topic associated with a version of the software component after application of the software update.

17. The computer readable storage medium of claim 15 additionally storing instructions to configure the processor to subscribe to the second topic of the topic tree upon determining that the desired version and the installed version differ.

18. The computer readable storage medium of claim 15 additionally storing instructions to configure the processor to unsubscribe from the second topic of the topic tree upon successful updating of the software component using the software update.

19. The computer readable storage medium of claim 15 additionally storing instructions to configure the processor to ignore a software update published to the second topic of the topic tree until receiving the notification of the desired version in the topic.

20. The computer readable storage medium of claim 15, wherein the published notification in the topic includes a configuration file, and additionally storing instructions to configure the processor to determine the desired version according to a version level of the software with which the configuration file is compatible.
