1. A vehicle, comprising:
- at least one engine component;
a sensor coupled to the at least one engine component and configured to monitor a vibration of the at least one engine component; and
a processor communicatively coupled to the sensor, the processor configured to;
determine a plurality of envelope spectrums based upon vibration data from the sensor;
determine fault frequencies for each of the at least one engine component based upon a rotating speed of each of the at least one engine component; and
monitor each envelope spectrum for changes at the determined fault frequencies,wherein the processor is further configured to determine the plurality of envelope spectrums based upon a minimum resonant frequency of the vibration data, a maximum resonant frequency of the vibration data, a step size for variable resonant frequency, a minimum bandwidth for an envelope window, a maximum bandwidth for the envelope window, and a step size for variable length of bandwidth.
