Apparatus, system and method of active noise control (ANC) in a vehicle

A vehicle comprising:

• a system bus to communicate information between a plurality of vehicular systems of the vehicle;
• and
• a sound control system configured to control sound within a sound control zone in the vehicle, the sound control system comprising:
• a plurality of acoustic transducers;
• a plurality of noise sensors to generate a plurality of noise inputs representing acoustic noise at a plurality of noise sensing locations;
• a plurality of residual-noise sensors to generate a plurality of residual-noise inputs representing acoustic residual-noise at a plurality of residual-noise sensing locations within the sound control zone;
• and
• a controller comprising logic and circuitry configured to determine a sound control pattern to control sound within the sound control zone and to output the sound control pattern to the plurality of acoustic transducers, the controller configured to determine the sound control pattern based on the plurality of noise inputs, the plurality of residual-noise inputs, and system bus information received via the system bus of the vehicle, wherein the controller is configured to determine a path transfer function setting of one or more path transfer functions based on the system bus information, and to determine the sound control pattern based on the path transfer function setting.

A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause a sound control system to control sound within a sound control zone in a vehicle, the instructions, when executed, to cause the sound control system to:

• process input information, the input information comprising:
• system bus information received via a system bus of the vehicle;
• a plurality of noise inputs representing acoustic noise at a plurality of noise sensing locations;
• and
• a plurality of residual-noise inputs representing acoustic residual-noise at a plurality of residual-noise sensing locations within the sound control zone in the vehicle;
• determine a sound control pattern to control sound within the sound control zone based on the system bus information, the plurality of noise inputs and the plurality of residual-noise inputs, wherein the instructions, when executed, cause the sound control system to determine a path transfer function setting of one or more path transfer functions based on the system bus information, and to determine the sound control pattern based on the path transfer function setting;
• and
• output the sound control pattern to a plurality of acoustic transducers.
