1. A vehicle component data analysis method, comprising the steps of:
- providing a first version of a behavior model of the component;
predicting behavior of the component as a function of said first version of the behavior model;
collecting performance data from the component during usage of the component;
comparing said predicted behavior with the data collected from the component;
determining when there is a discrepancy between the predicted component behavior and the collected performance data;
determining whether said discrepancy results from a failure of said component; and
if said discrepancy did not result from a failure of said component, modify the first version of the behavior model.

Abstract
A method and system for an improved vehicle monitoring system in order to provide a cost-effective and scalable system design for industrial application through the use of machine learning and data mining technologies on data acquired from a plurality of vehicles to create models. Frequent acquisition of vehicle sensor and diagnostic data enables comparison with the created models to provide continuing analysis of the vehicle with respect to repair, maintenance and diagnostics.
