Abstract: Vehicles and systems and methods for health monitoring drive unit bearings in vehicles are provided. A system for health monitoring a drive unit bearing in a vehicle includes a sensor mounted to a drive unit of the vehicle and configured to provide a vibration signal; and a processor configured to: pre-process the vibration signal from the sensor to enhance a fault signature and form a frequency domain signal; and process the frequency domain signal to estimate a health stage of the drive unit bearing.
