Abstract

A method includes receiving a stream of sensor data regarding operating conditions of a vehicle, and processing first and second data sets of the stream of sensor data in time and frequency domains. The method also includes identifying differences within and between processing results from processing the first and second data sets, and determining that at least one difference in the identified differences is greater than or equal to one or more predefined thresholds. Further, the method includes, based on determining the at least one difference in the identified differences being greater than or equal to the one or more predefined thresholds, recording one or more processing results corresponding to the identified at least one difference in a data index map (DIM), and analyzing contents of the DIM to evaluate operating conditions of the vehicle.
