Abstract

A method and system for performing diagnostics or software maintenance on a vehicle comprises recording high-fidelity data at the vehicle consistent with configuration files to support engineering analysis or diagnostics on vehicle components, systems or performance. Supplemental data is retrieved via a low bandwidth transmission at the vehicle to supplement the recorded high-fidelity data. The recorded high-fidelity data and retrieved supplemental data is processed to generate a diagnostic status report message from transmission to the central electronic data processing system. A data processor or central electronic data processing system organizes the diagnostic report message, the recorded high fidelity data and the retrieved supplemental data into a data mart or diagnostics database to support engineering analysis or diagnostics on vehicle components, systems or performance.

Claims

1. A method of performing remote diagnostic on a vehicle, the method comprising:

recording high-fidelity data by a controller at the vehicle for aggregation prior to transmission via a vehicle data bus for processing by vehicle electronics on the vehicle where the vehicle data bus does not have sufficient bandwidth or transmission rate capacity to transmit the high-fidelity data in real-time as it is collected, the high-fidelity data being consistent with configuration files to support engineering analysis or diagnostics on vehicle components, systems or performance, the high-fidelity data comprising higher sampling rate data that is gathered at higher sampling rates than those required by the controllers to perform non-diagnostic features during normal vehicle operation;

retrieving supplemental data via a low bandwidth transmission at the vehicle to supplement the recorded high-fidelity data, where the supplemental data is collected at a lower sampling rate than the higher sampling rate of the hiqh-fidelity data;

processing, by the vehicle electronics, the recorded high-fidelity data and retrieved supplemental data to generate a diagnostic status report message for transmission to a central electronic data processing system;

organizing the diagnostic report message, the recorded high fidelity data and the retrieved supplemental data into a data mart or diagnostics database to support engineering analysis or diagnostics on vehicle components, systems or performance.

2. The method according to claim 1 wherein the high-fidelity data comprises higher sampling rate data that is gathered at higher than normal sample rate during normal vehicle operation to identify a problem with the vehicle, a vehicle system, or a vehicle component.

3. The method according to claim 1 wherein the low bandwidth transmission comprises a wireless transmission between vehicle electronics and the central electronic data processing system or another remote data processing system, where the bandwidth is limited to meet or exceed a certain minimum threshold of reliability or signal quality or to comply with a bandwidth limitation provided by a satellite or other wireless service provider.

4. The method according to claim 1 wherein the organizing comprises identifying trends in the diagnostic database.

5. The method according to claim 1 further comprising:

determining status or progress of diagnostic requests; and

displaying the determined status to a user at a user terminal in communication with the central electronic data processing system.

6. The method according to claim 1 further comprising:

displaying real-time data readings from a vehicle to a user at a user terminal in communication with the central electronic data processing system.

7. The method according to claim 1 comprising:

supporting customer selection of a service center to remotely service a vehicle via settings selectable via web-site.

8. The method according to claim 1 further comprising:

running tests on the vehicle via a remote terminal in communication with at least one of the vehicle electronics and the central electronic data processing system.

9. The method according to claim 8 further comprising:

performing automatic recalibration of components of the vehicle electronics that are out of a target range of parameter values.

10. The method according to claim 1 further comprising:

billing system users on a per use basis for remote diagnostic and programming sessions.

11. The method according to claim 1 wherein high-fidelity data comprises a measured event or data that is sampled at a higher sampling rate with a sampling interval that is less than a total delay over a vehicle data bus, where the total delay includes a sum of a propagation delay over the maximum length of the vehicle data bus, a controller processing delay, and a controller transceiver delay.

12. The method according to claim 1 wherein the high-fidelity data is collected via a data collector in an engine controller and wherein the high-fidelity data comprises data related to fuel injection events or fuel metering system events.

13. The method according to claim 1 further comprising:

storing and aggregating the high-fidelity data in a data storage device associated with the vehicle electronics for later transmission over a vehicle data bus.

14. The method according to claim 13 wherein the retrieving of the supplemental data via the low bandwidth transmission is transmitted in real-time via the vehicle data bus.

15. The method according to claim 1 further comprising:

reporting or transmitting pertinent high-fidelity data to the central electronic data processing system.

16. The method according to claim 1 further comprising:

presenting, via a user interface on the vehicle, a list of service centers for resolving one or more technical issues or problems identified by the diagnostic report message.

17. A system of performing remote diagnostic on a vehicle, the system comprising:
