Abstract

A computer implemented method includes wirelessly receiving data from a proximate vehicle computing system, the data comprising at least a portion of a complete software process. The method also includes storing the received data and evaluating whether the stored data, in conjunction with any previously stored data, constitutes the entire complete software process. The method further includes executing the entire complete software process, conditional on the evaluating.

Claims

1. A computer implemented method comprising:

wirelessly receiving data in a first vehicle from a vehicle computing system in a proximate second vehicle, the data comprising at least a portion of a complete software process;

storing the received data;

evaluating whether the stored data, in conjunction with any previously stored data, constitutes an entirety of the complete software process; and

conditional on the evaluating, executing the complete software process.

2. The method of claim 1, wherein the data is received over a mobile mesh network.

3. The method of claim 1, wherein the software process is a test process.

4. The method of claim 1, wherein the software process is a software update.

5. The method of claim 4, further comprising:

detecting that a vehicle is in a parked state;

notifying a user that the entirety of the complete software process has been stored;

and wherein the executing further includes executing the complete software process after a user has indicated that execution is permissible.

6. The method of claim 5, wherein the executing further includes:

requesting a verification code from the user;

utilizing an input verification code to validate the software update; and

executing the complete software process contingent on the verification of the software update.

7. The method of claim 1, wherein the wirelessly receiving further includes, responsive to a request for specific data, wirelessly receiving at least a portion of the specific data from the proximate vehicle computing system.

8. A system comprising a plurality of vehicles, each having a transceiver and a vehicle computing system, wherein the respective vehicle computing systems are configured to transfer and store portions of a software update therebetween, such that one or more of the vehicles eventually stores an entire version of the software update, having been completely received in portion form from more than one of the plurality of vehicles.

9. The system of claim 8, wherein each vehicle is configured to broadcast any portion of the software update currently stored in a memory of that vehicle.

10. The system of claim 8, wherein at least one of the vehicle computing systems is configured to execute the software update to update a vehicle software module, once the entire version of the software update is stored in a memory of that vehicle.

11. The system of claim 10, wherein at least one of the vehicle computing systems is configured to wait until a vehicle is in a parked state before executing the software update.

12. The system of claim 11, wherein at least one of the vehicle computing systems is configured to wait for user permission before executing the software update.

13. The system of claim 12, wherein at least one of the vehicle computing systems is configured to wait for an input authentication code before executing the software update.

14. The system of claim 8, wherein at least one of the vehicles is configured to randomly broadcast differing portions of the software update at intervals.

15. The system of claim 8, wherein at least one of the vehicles is configured to responsively transfer at least a portion of the software update in response to a request from another of the vehicles.

16. A computer implemented method comprising:

receiving test code from a proximate vehicle computing system;

executing the test code to produce a test result;

reporting the test result back to a known remote server; and

transmitting the received test code to a different proximate vehicle computing system.

17. The method of claim 16, wherein the reporting is done by a vehicle computing system in wireless communication with the remote server through a wireless link established through a wireless device in wireless communication with the vehicle computing system.

18. The method of claim 16, wherein the receiving test code further includes receiving only a portion of test code from a first proximate vehicle computing system, and receiving a remaining portion of test code from one or more other proximate vehicle computing systems.

19. The method of claim 16, wherein the transmitting further includes transmitting a portion of the received test code.

20. The method of claim 19, wherein the transmitting further includes transmitting a received portion of the received test code before a completed version of the test code has been received.
