Abstract
A system for actively mitigating a buffeting noise in an occupant compartment of a vehicle when the vehicle is moving. The system is configured to determine an estimated effective volume of the occupant compartment, and to determine if a single window of the vehicle occupant compartment is open. Responsive to a determination that a single window of the vehicle occupant compartment is open, and using the estimated effective volume of the occupant compartment, an estimated buffeting noise frequency is determined. Responsive to the estimated buffeting noise frequency, the system determines characteristics of a sound configured to cancel a buffeting noise generated inside the occupant compartment while the vehicle is moving. The system may then control operation of a noise cancelling signal generating system to generate the sound having characteristics configured to cancel the buffeting noise inside the occupant compartment.
