Abstract

A method and system are provided for secure over-the-air modification of vehicular options by a vehicle user. The system includes a vehicle and a secure server. The vehicle includes receiver circuitry for receiving and demodulating wireless signals and a controller coupled to the receiver. The secure server is accessible by the vehicle user and generates a vehicular option modification package for provision to the vehicle by generating option parameter modification instructions in response to user parameter modification requests from the vehicle owner and generating authentication information in response to unique server authentication information associated with the secure server. The vehicle'"'"'s receiver demodulates received wireless signals to generate the vehicular option modification package and the vehicle'"'"'s controller authenticates the vehicular option modification package and, when the vehicular option modification package is authenticated, modifies the vehicular options of the vehicle in response to the parameter modification instructions.

Claims

1. A method for over-the-air modification of vehicular options via a client server, the vehicular options being stored in an on-vehicle control module, the method comprising the steps of:

accessing an secure server;

transmitting a user parameter modification request to the secure server;

receiving an option parameter modification instruction generated by the secure server and authentication information in response to the user parameter modification request transmitted to the secure server;

verifying the authentication information by the vehicle control module with vehicle authentication information stored in the vehicle; and

modifying the vehicular options of the vehicle in response to the option parameter modification instruction received from the secure server when the authentication information is verified correctly against the vehicle authentication information stored in the vehicle.

2. The method in accordance with claim 1 wherein the authentication information includes an electronic signature that is unique to the secure server and the step of modifying the vehicular options comprises the step of modifying the vehicular options of the vehicle in response to the option parameter modification instruction when the electronic signature is verified correctly against at least a portion of the vehicle authentication information.

3. The method in accordance with claim 1 further comprising the step of combining the option parameter modification instruction with the authentication information having unique authentication information associated with the secure server to generate a vehicular option modification package.

4. The method in accordance with claim 3 further comprising the step of transmitting the vehicular option modification package in response to the option parameter modification instruction.

5. The method in accordance with claim 4 further comprising the steps of:

transmitting the vehicular option modification package from the secure server to a wireless access point; and

transmitting the vehicular option modification package from the wireless access point to the vehicle.

6. The method in accordance with claim 3 wherein the step of accessing the secure server comprises the step of coupling an information handling device to the secure server, and wherein the step of transmitting a user parameter modification request to the secure server comprises the steps of:

generating the user parameter modification request with the information handling device in response to a user input; and

transmitting the user parameter modification request from the information handling device to the secure server.

7. The method in accordance with claim 6 further comprising the steps of:

transmitting the vehicular option modification package from the secure server to the information handling device; and

transmitting the vehicular option modification package to the vehicle.

8. The method in accordance with claim 7 wherein the step of the transmitting the vehicular option modification package to the vehicle comprises the steps of:

transmitting the vehicular option modification package to a wireless access point; and

transmitting the vehicular option modification package from the wireless access point wirelessly to the vehicle.

9. The method in accordance with claim 1 wherein the vehicular options comprise a vehicle display language option.

10. A method for generating a vehicular option modification package for over-the-air modification of vehicular options by a vehicle user, the method comprising the steps of:

coupling an information handling device accessible by the vehicle user to a secure server;

generating user parameter modification information with the information handling device in response to user inputs received from the vehicle user;

transmitting the user parameter modification information from the information handling device to the secure server;

generating a parameter modification instruction at the secure server in response to user parameter modification information received by the information handling device; and

combining the parameter modification instruction with authentication information that is verifiable compared to vehicle authentication information stored in an onboard vehicle control module having unique authentication information associated with the secure server to generate a vehicular option modification package.

11. The method in accordance with claim 10 wherein the step of coupling the information handling device to the secure server comprises the step of the information handling device accessing a secure website hosted by the secure server via an internet connection.

12. The method in accordance with claim 11 wherein the step of generating the parameter modification instruction comprises the steps of:

transmitting a listing of one or more programmable vehicular options from the secure server to the information handling device; and

transmitting the user parameter modification information from the information handling device to the secure server, the user parameter modification information including information selecting one or more of the one or more programmable vehicular options.

13. A system for over-the-air modification of vehicular options by a vehicle user, the system comprising:

a transmitter configured to transmit a user modification request and authentication information to a secure server;

a receiver configured to receive an option parameter modification instruction generated by the secure server in response to the user modification request and authentication information; and

a controller coupled to the receiver and configured to;

verify the authentication information against authentication information stored in a vehicle; and

modify the vehicular options of the vehicle in response to the option parameter modification instruction when the authentication information is verified against the authentication information stored in the vehicle.

14. The system of claim 13 further comprising an information handling device accessible by the vehicle user, wherein the information handling device is coupleable to the secure server for generating the user modification request in response to user inputs by the vehicle user and configured to provide the user modification request to the secure server.

15. The system of claim 14 wherein the information handling device is coupleable to the secure server via an internet connection.

16. The system of claim 15 wherein the information handling device is configured to provide the user modification request to the secure server by accessing a secure webpage via an internet connection.

17. The system of claim 14 wherein the information handling device is further coupleable to receive the vehicular option modification package from the secure server and providing the vehicular option modification package to vehicle.

18. The system of claim 17 further comprising a wireless access point coupleable to the information handling device, the wireless access point configured to forward the vehicular option modification package to the vehicle in response to a user input from the vehicle user.

19. The system of claim 13 wherein the vehicular options comprise a vehicle lighting option.

20. The system of claim 13 wherein the vehicular options comprise a factory default option.
