Abstract
A system for noise localization for a vehicle includes a plurality of vehicle sensors. The plurality of vehicle sensors includes at least one of a microphone, a vibration sensor, a vehicle road speed sensor, and a vehicle motor speed sensor. The system also includes a controller in electrical communication with the plurality of vehicle sensors. The controller is programmed to perform a plurality of measurements of a noise produced by a defective part of the vehicle using the plurality of vehicle sensors. The controller is further programmed to determine a location of the defective part within the vehicle based at least in part on the plurality of measurements using at least one of a machine learning based method and an analytical method. The controller is further programmed to identify the defective part of the vehicle based at least in part on the location of the defective part within the vehicle.
