SYSTEMS AND METHODS FOR ENGINE DIAGNOSIS USING WAVELET TRANSFORMATIONS
First Claim
Patent Images
1. A method for performing diagnosis on an engine of a vehicle, the method comprising the steps of:
- obtaining data for a plurality of variables pertaining to the engine;
transforming the data with respect to each of the plurality of variables using a wavelet transformation, to thereby generate initial coefficients for each of the plurality of variables; and
aggregating the initial coefficients for each of the plurality of variables, to thereby generate an aggregate set of coefficients for the plurality of variables.

Abstract
A method for performing diagnosis on an engine includes the steps of obtaining data for a plurality of variables pertaining to the engine, transforming the data with respect to each of the plurality of variables using a wavelet transformation, to thereby generate initial coefficients for each of the plurality of variables, and aggregating the initial coefficients for each of the plurality of variables, to thereby generate an aggregate set of coefficients for the plurality of variables.
