Abstract

A vehicle computing system having a computer processor in communication with a wireless transceiver, such that the wireless transceiver is capable of communication with a wireless communication device located remotely from the processor. The computer processor may be configured to receive input identifying at least one checksum value from one or more modules in the vehicle. The computer processor may transmit the at least one checksum value to a remote server through the wireless communication device. The remote server may compare the at least one checksum value to a predetermined value. Based on the compared results, the processor may receive one or more messages from the remote server to indicate whether the at least one checksum is equal to the predetermined value. The processor may generate one or more remedial actions if the at least one checksum is not equal to the predetermined value.

Claims

1. A vehicle computing system comprising:

a computer processor in communication with a wireless transceiver, the wireless transceiver capable of communication with a wireless communication device located remotely from the processor, the computer processor configured to;

receive input identifying at least one checksum value from one or more modules in the vehicle;

transmit the at least one checksum value to a remote server through the wireless communication device, such that the remote server compares the at least one checksum value to a predetermined value;

receive one or more messages from the remote server to indicate whether the at least one checksum is equal to the predetermined value; and

generate one or more remedial actions if the at least one checksum is not equal to the predetermined value.

2. The vehicle computing system of claim 1 wherein the computer processor is additional configured to update the one or more modules with software stored at the remote server.

3. The vehicle computing system of claim 2 wherein the update of the one or more modules is initiated on a vehicle key-on initialization or key-off event.

4. The vehicle computing system of claim 3 wherein the vehicle key-on initialization may prepare the update of the one or more modules based on input received from one or more infotainment nobs to accept the software from the remote server.

5. The vehicle computing system of claim 1 wherein the one or more remedial actions includes outputting a message to a display.

6. The vehicle computing system of claim 1 wherein the wireless communication device located remotely from the processor is an embedded cellular phone in the vehicle.

7. The vehicle computing system of claim 1 wherein the wireless communication device located remotely from the processor is a portable cellular phone.

8. A vehicle computing system comprising:

a computer processor in communication with a wireless transceiver, the wireless transceiver capable of communication with a server located remotely from the processor, the computer processor configured to;

receive input identifying a test value from one or more modules in a vehicle;

transmit the test value to the server such that the server evaluates the test value to determine if the test value is correct or incorrect;

receive one or more messages from the server to indicate whether the test value is correct or incorrect; and

generate one or more remedial actions if the test value is not correct.

9. The vehicle computing system of claim 8 wherein the computer processor is additional configured to update the one or more modules with software stored at the server.

10. The vehicle computing system of claim 9 wherein the update of the one or more modules may be initiated with input received from one or more infotainment nobs.

11. The vehicle computing system of claim 8 wherein the one or more remedial actions includes a reduce powertrain power mode.

12. The vehicle computing system of claim 11 wherein the reduce powertrain power mode limits vehicle acceleration.

13. The vehicle computing system of claim 8 wherein the wireless transceiver is an embedded WiFi transceiver.

14. The vehicle computing system of claim 8 wherein the one or more remedial actions include outputting a message to an instrument cluster.

15. A method comprising:

receiving input identifying a test value from one or more modules in a vehicle;

transmitting the test value to a server such that the server evaluates the test value to determine if the test value is correct or incorrect;

receiving one or more messages from the server to indicate whether the test value is correct or incorrect; and

generating one or more remedial actions if the test value is not correct.

16. The method of claim 15 wherein the one or more remedial actions include a reduce powertrain power mode.

17. The vehicle computing system of claim 16 wherein the reduce powertrain power mode may limit vehicle speed.

18. The method of claim 15 wherein the one or more remedial actions includes outputting a message to a display.

19. The method of claim 18 wherein the display is a portable cellular phone in communication with the vehicle.

20. The method of claim 19 wherein the portable cellular phone in communication with the vehicle is linked by BLUETOOTH technology.
