Rattling detection process for vehicle, involves normalizing instantaneous noise energy according to corrected theoretical noise energy and filtering noise energy according to average of instantaneous noise energy
The process involves determining theoretical noise energy and measuring instantaneous noise energy. The theoretical noise energy is corrected according to an average of the instantaneous noise energy. The instantaneous noise energy is normalized according to the corrected noise energy. The normalized noise energy is filtered according to the average. The noise energy before filtering and the filtered noise energy are compared.
