Diagnostics data collection and analysis method and apparatus to diagnose vehicle component failures
First Claim
1. A computer-implemented method of analyzing vehicle test data to diagnose a failure mode of a vehicle component, comprising:
- compiling a collection of historical test data points each of which includes at least one operational parameter measurement of an individual vehicle; and
defining a range corresponding to an operating condition of a vehicle type based on the collection of test data points.

Abstract
A vehicle diagnostic data collector/analyzer compiles historical vehicle diagnostic data, including measured operating parameters from a number of different vehicles operating under a variety of normal vehicle operating conditions and vehicle component failure conditions, and performs statistical analyses on various vehicle type/operating condition combinations to establish operating parameter ranges corresponding to normal operating conditions and various failure conditions. The diagnostic data collector/analyzer also measures real-time operating parameters on specific test-subject vehicles and evaluates similarities and differences between the measured operating parameters and the established ranges, and correlates the test data with known operating conditions in order to diagnose potential failure modes of vehicle components.
