Vehicle including noise management system having automotive audio bus (a2b) interface

A noise management system installed in a vehicle, the noise management system comprising:

• an automotive audio bus (A2B) interface configured to transfer data thereon;
• at least one first sensor configured to monitor an exterior environment of the vehicle and at least one second sensor configured to monitor an interior environment of the vehicle, the at least one first sensor configured to output first data to the A2B interface indicative of exterior noise and the at least one second sensor configured to output second data to the A2B interface indicative of interior noise;
• and
• a plurality of noise cancellation and enhancement (NCE) controllers connected to the A2B interface, the plurality of NCE controllers configured to generate post-processed data in response to performing a noise management signal processing operation based on at least one of the first and second data received from the A2B interface,
• wherein the post-processed data is converted into an audio signal that is output so as to at least one of suppress and enhance the exterior noise.

A method of managing noise associated with an automotive vehicle, the method comprising:

• detecting, using at least one sensor, noise existing in an exterior portion of the vehicle and an interior portion of the vehicle, and outputting at least one noise signal indicative of the detected noise;
• performing, with a first noise cancellation and enhancement (NCE) controller, a first noise management signal processing operation based on the at least one noise signal, and performing, with a second NCE controller, a second noise management signal processing operation based on the at least one noise signal;
• receiving, by an automotive audio bus (A2B) interface, a first post-processed signal from the first NCE controller and a second post-processed signal from the second NCE controller;
• converting, by a third NCE controller different from the first and second NCE controllers, the first and second post-processed signals into an audio signal;
• and
• outputting the audio signal into the interior portion of the vehicle so as to at least one of suppress and enhance noise associated with the exterior portion of the vehicle.
