Abstract

A method for reduces the amount of information relating to the status of a vehicle relayed from the vehicle to a remote location over a communications data link. The method includes the steps of generating a fault code, delivering the fault code to the remote location across the data link, and receiving the fault code at the remote location and responsively generating a data request signal. The data request signal is delivered to the vehicle over the data link, and vehicle information is generated and delivered to the remote location over the data link.

Claims

1. A method for reducing the amount of information relating to the status of a vehicle being relayed from the vehicle to a remote location over a communications data link, including the steps of:

generating a fault code;

delivering said fault code to the remote location across the data link;

receiving said fault code at, the remote location and responsively analyzing said fault code in view of the vehicle history;

generating a data request signal if warranted by said fault code and said vehicle history;

delivering said data request signal to the vehicle over the data link;

receiving said data request signal and responsively generating vehicle information; and

delivering said generated vehicle information to the remote location over the data link.

2. A method, as set forth in claim 1, including the steps of:

receiving said vehicle information;

analyzing said vehicle information and responsively generating repair instructions; and

delivering said repair instructions to the vehicle over the data link.

3. A method, as set forth in claim 2, including the step of delivering said repair instructions to a service center.

4. A method, as set forth in claim 1, wherein the step of generating a fault code includes the steps of:

detecting the triggering of a driver fault button, and

responsibly determining said fault code.

5. A method, as set forth in claim 1, wherein the step of generating a fault code includes the steps of:

detecting a prognostic fault, and

responsibly producing said fault code.

6. A method, as set forth in claim 1, wherein the step of generating a fault code includes the steps of:

detecting a diagnostic fault, and

responsibly producing said fault code.

7. A method, as set forth in claim 1, wherein the step of generating a fault code includes the steps of:

detecting one of a triggering of a driver fault button, a prognostic fault, and a diagnostic fault, and

responsibly producing said fault code.

8. A method for reducing the amount of information relating to the status of a vehicle being relayed from the vehicle to a remote location, including the steps of:

generating a fault code;

delivering said fault code at the remote location across a satellite communications data link;

receiving said fault code at the remote location and responsively analyzing said fault code in view of the vehicle history;

generating a data request signal if warranted by said fault code and said vehicle history;

delivering said data request signal to the vehicle over the satellite communications data link;

receiving said data request signal and responsively generating vehicle information;

delivering said generated vehicle information to the remote location over the satellite communications data link;

receiving said vehicle information at the remote location;

analyzing said vehicle information and responsively generating repair instructions; and

delivering said repair instructions to the vehicle over the satellite communications data link.

9. A method, as set forth in claim 8, including the step of delivering said repair instructions to a service center.

10. A method, as set forth in claim 8, wherein the step of generating a fault code includes the steps of:

detecting one of a triggering of a driver fault button, a prognostic fault, and a diagnostic fault, and

responsively determining said fault code.
