SYSTEM AND METHOD FOR MONITORING HEALTH OF DRIVE UNIT GEARS

Abstract: a computer-implemented method includes receiving sensor data associated with a drive unit and one or more vehicle operating parameters, transforming sensor data into a phase domain based on the one or more vehicle operating parameters, after transforming the sensor data, filtering the sensor data to isolate a gear fault signature from one or more operational signatures associated with the drive unit, separating the gear fault signature into a plurality of gear fault signature segments, extracting one or more health indicators from each of the gear fault signature segments, determining whether each of the one or more extracted health indicators exceeds a threshold health indicator, when at least one of the one or more extracted health indicators exceeds the threshold health indicator, generating a gear health notification indicating a fault condition of the drive unit.
