Abstract

A communication system and a method of using the communication system to install a vehicle update in a vehicle system module (VSM) onboard a vehicle while enabling the vehicle to remain in a mobilized state during the installation of the vehicle update. The method includes the steps of receiving a vehicle update for a target VSM in the vehicle while the vehicle is in the mobilized state; performing a hand-off operation procedure between a proxy device and the target VSM so that the proxy device is granted permission to execute vehicle operating instructions as if the proxy device is the target VSM; thereafter, installing the vehicle update at the target VSM; and continuing operation of the vehicle in the mobilized state using the proxy device instead of the target VSM during the installing step.

Claims

1. A method of installing a vehicle update in a vehicle system module (VSM) onboard a vehicle while enabling the vehicle to remain in a mobilized state during the installation of the vehicle update, the method comprising the steps of:

receiving a vehicle update for a target VSM in the vehicle while the vehicle is in the mobilized state;

performing a hand-off operation procedure between a proxy device and the target VSM so that the proxy device is granted permission to execute vehicle operating instructions as if the proxy device is the target VSM;

thereafter,

installing the vehicle update at the target VSM; and

continuing operation of the vehicle in the mobilized state using the proxy device instead of the target VSM during the installing step.

2. The method of claim 1, wherein a gateway module in the vehicle receives the vehicle update from the proxy device, wherein the gateway module installs the vehicle update in the target VSM.

3. The method of claim 1, wherein the gateway module is coupled to the target VSM via a vehicle bus, wherein the gateway module is coupled to the proxy device via a short range wireless communication (SRWC) link.

4. The method of claim 1, wherein the proxy device is a mobile device having application software installed thereon adapted to execute the vehicle operating instructions of the target VSM.

5. The method of claim 1, wherein the proxy device is a gateway module in the vehicle or another VSM in the vehicle.

6. The method of claim 1, further comprising:

receiving the vehicle update at a mobile device;

prior to the receiving the vehicle update for the target VSM, installing the vehicle update at the mobile device so that the mobile device may execute the vehicle operating instructions associated with the continuing vehicle operations; and

providing the vehicle update from the mobile device to a gateway module having a communication link with the target VSM.

7. The method of claim 1, further comprising:

in response to the installing step, performing a reverse hand-off operation procedure between the proxy device and the target VSM so that the target VSM is granted permission to begin executing vehicle operating instructions again in the vehicle, wherein the target VSM executes a different set of operating instructions than it did prior to the installation.

8. The method of claim 7, wherein the different set of operating instructions are identical to the operating instructions executed by the proxy device while the vehicle update was being installed in the target VSM.

9. The method of claim 1, wherein the target VSM is one of an engine control module (ECM), a powertrain control module (PCM), or a body control module (BCM).

10. A computer program product, comprising a non-transitory computer-readable medium for a mobile device, comprising computer program instructions that enable the mobile device to execute temporarily an updated set of operating instructions on behalf of a vehicle system module (VSM) in a vehicle while the updated set of operating instructions is being installed therein, thereby enabling the vehicle to remain in a mobilized state during the installation, said computer program product comprising:

instructions for receiving the updated set of operating instructions at the mobile device from a remote server;

instructions for communicating with the vehicle via a gateway module therein in response to the receiving step; and

instructions for performing a hand-off operation procedure in response to receiving a readiness message from the gateway module, wherein, during the hand-off operation procedure, the mobile device executes the updated set of operating instructions for the vehicle via the gateway module so that the vehicle may continue operations while the gateway module installs the updated set of operating instructions in the VSM.

11. The computer program product of claim 10, further comprising:

instructions for performing a reverse hand-off operation procedure in response to receiving a completion message from the gateway module indicating that the installation is complete, wherein, during the reverse hand-off operation procedure, the mobile device ceases to execute the updated set of operating instructions for the vehicle so that the VSM may begin to execute the updated set of operating instructions.

12. The computer program product of claim 10, further comprising instructions for communicating with the vehicle via the gateway module via a short range wireless communication (SRWC) link.

13. The computer program product of claim 12, wherein communications associated with the hand-off operation procedure occur via the SRWC link between the mobile device and the gateway module, wherein the gateway module installs the updated set of operating instructions in the VSM via a vehicle bus.

14. The computer program product of claim 10, wherein the instructions for performing a hand-off operation procedure are executed while the gateway module installs the updated set of operating instructions in one of an engine control module (ECM), a powertrain control module (PCM), or body control module (BCM).

15. The computer program product of claim 10, wherein the instructions for performing the hand-off operation procedure are automated.
