Abstract

A method for providing a secure communications link between a home PC and a vehicle through a wireless access point. The method includes providing a wireless connection between a vehicle communications system and the wireless access point and causing a user of the PC to initiate a communication with the vehicle communications system through the wireless access point so as to allow the user to send information to the vehicle from the home PC. The method also includes causing the vehicle communications system to send an authentication challenge to the PC, such as identifying a user name and password, to authorize the user to communicate with the vehicle communications system, and establishing a secure communications link between the vehicle communications system and the PC if the user responds to the challenge with a correct response.

Claims

1. A method for securing a communications link between a vehicle communications system and a computer through a wireless access point, said method comprising:

providing a wireless connection between the vehicle communications system and the wireless access point;

providing a connection between the computer and the wireless access point;

causing a user of the computer to initiate a communication with the vehicle communications system through the wireless access point;

causing the vehicle communications system to send a challenge to the computer to authenticate the user; and

establishing a secure communications link between the vehicle communications system and the computer if the computer responds to the challenge with a correct response.

2. The method according to claim 1 wherein the computer communicates with the vehicle communications system through a web browser.

3. The method according to claim 1 wherein the computer is a home personal computer.

4. The method according to claim 1 wherein providing a connection between the computer and the wireless access point includes providing a hard-wired connection between the computer and the wireless access point.

5. The method according to claim 1 wherein the challenge includes identifying a proper user name and password.

6. The method according to claim 1 wherein the challenge is a shared secret.

7. The method according to claim 1 wherein the vehicle communications system provides configuration network pages to the computer to allow the user to make changes to the vehicle once the secure communications link has been established.

8. The method according to claim 1 wherein the user uses the secure communications link to personalize and customize various vehicle systems.

9. The method according to claim 1 wherein the user uses the secure communications link to download digital music to the vehicle.

10. The method according to claim 1 wherein the user uses the secure communications link to download pre-computed navigation directions to the vehicle.

11. A method for securing a communications link between a vehicle communications system and a computer through a wireless access point, said method comprising:

providing a wireless connection between the vehicle communications system and the wireless access point;

providing a connection between the computer and the wireless access point;

causing a user of the computer to initiate a communication with the vehicle communications system through the wireless access point using a web browser;

causing the vehicle communications system to send an authentication network page to the computer asking the user for a user name and password;

establishing a secure communications link between the vehicle communications system and the computer if the computer provides a correct user name and password; and

providing configuration network pages to the computer to allow the user to make changes to the vehicle once the secure communications link has been established.

12. The method according to claim 11 wherein the computer is a home personal computer.

13. The method according to claim 11 wherein providing a connection between the computer and the wireless access point includes providing a hard-wired connection between the computer and the wireless access point.

14. The method according to claim 11 wherein the user uses the secure communications link to personalize and customize various vehicle systems.

15. The method according to claim 11 wherein the user uses the secure communications link to download digital music to the vehicle.

16. The method according to claim 11 wherein the user uses the secure communications link to download pre-computed navigation directions to the vehicle.

17. A method for securing a communications link between a vehicle communications system and a computer through a wireless access point, said method comprising:

providing a wireless connection between the vehicle communications system and the wireless access point;

providing a connection between the computer and the wireless access point; and

causing the vehicle communications system to verify that a user of the computer is authenticated to communicate with the vehicle before allowing the user to change vehicle settings wirelessly from the computer.

18. The method according to claim 17 wherein the computer is a home personal computer.

19. The method according to claim 17 wherein providing a connection between the computer and the wireless access point includes providing a hard-wired connection between the computer and the wireless access point.

20. The method according to claim 17 wherein the vehicle communications system verifies that a user of the computer is authorized to communicate with the vehicle by asking the user for a user name and password.
