Abstract

A motor vehicle includes a body comprising a chassis, walls delimiting a passenger compartment, at least one actuator applied to a corresponding wall between said walls and controllable through a control input signal to transmit a vibration corresponding to the control input signal to the corresponding wall, thereby producing a corresponding sound inside the passenger compartment, an error sensor configured to detect a quantity indicative of a residual sound produced by a superposition of said sound with an interior noise inside the passenger compartment and to generate a related error signal, and a control unit coupled to the error sensor to receive the error signal, configured to execute an active noise cancellation algorithm based on the error signal, so as to determine the control input signal adapted to minimize or reduce the residual sound, and further configured to control the actuator with the determined control input signal.
