Method and system for performing diagnostics or software maintenance for a vehicle

摘要

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.

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.
