1. A method for collecting and analyzing vehicle data, said method comprising:
- collecting data from service shops;
collecting data from on-road vehicles using wireless communications, where the vehicles use a microprocessor for monitoring and transmitting the data;
collecting warranty record data;
automatically aggregating the collected data and using knowledge extraction to extract information from the aggregated data;
providing on-board and off-board diagnosis and prognosis algorithm enhancement using the extracted information, where providing the algorithm enhancement includes using case based reasoning, Bayesian networks, rule data bases or a reasoning engine; and
upgrading each vehicle'"'"'s algorithms using problem information collected from the other on-road vehicles, andusing the enhanced algorithms to provide various vehicle services.

Abstract
A system and method for telemetrically collecting on-road vehicle diagnostic data. In one embodiment, the method includes collecting vehicle diagnostic data from service shops, on-road vehicles and warranty records, aggregating the collected data and extracting knowledge therefrom. The extracted knowledge can be used to enhance algorithms on-board vehicles or at service centers so as to better identify vehicle faults and provide enhanced diagnostics and prognostics. The enhanced algorithms can then be used to provide predictive maintenance suggestions, provide trouble shooting assistance or provide vehicle design improvements.
