Abstract
A fault detection method for determining whether a fault exists with a rotating element of a vehicle that includes a transduce, a diagnosis sampler, and a controller. The transducer converts sounds to an electrical signal that includes a noise component generated from the rotating element. The diagnosis sampler provides a sample of the electrical signal to the controller, which has functional aspects such as an envelope detect, a spectrum analysis, and a fault detect. The envelope detect detects an envelope of the electrical signal. The spectrum analysis forms a spectra from the envelope of the electrical signal, where the spectra is associated with the noise component generated from the rotating element. The fault detect determines (from the formed spectra) whether the fault exists with the rotating element.
