Selective noise cancellation for a vehicle

A method for performing selective active noise cancellation (ANC) for a vehicle, the method comprising:

• generating reference signals via a plurality of reference sensors positioned external to a vehicle cabin, the reference signals being indicative of at least one of road noise and engine noise that is external to the vehicle cabin;
• generating a first cancellation field via at least one first loudspeaker that is positioned in a first zone of the vehicle, the first cancellation field cancelling the at least one of road noise and engine noise in the first zone;
• generating a second cancellation field via at least one second loudspeaker that is positioned in a second zone of the vehicle, the second cancellation field cancelling the at least one of road noise and engine noise in the second zone;
• generating a plurality of error signals via a plurality of error microphones that is positioned in the first zone and the second zone of the vehicle;
• determining an amount of noise present in the first zone and the second zone;
• selectively driving only the at least one first loudspeaker in the first zone to generate the first cancellation field in response to the amount of noise present in the first zone being greater than the amount of noise present in the second zone of the vehicle;
• selectively driving only the least one second loudspeaker in the second zone to generate the second cancellation field in response to the amount of noise present in the second zone being greater than the amount of noise present in the first zone of the vehicle;
• and
• training a first adaptive filter to reach a first predetermined noise level while driving only the at least one first loudspeaker to provide the first cancellation field and while disabling the at least one second loudspeaker from generating the second cancellation field.

A computer-program product embodied in a non-transitory computer readable medium that is programmed to perform selective active noise cancellation (ANC) for a vehicle, the computer-program product comprising instructions to:

• determine an amount of noise present in a first zone and a second zone of the vehicle;
• and
• selectively drive only at least one first loudspeaker in the first zone to generate a first cancellation field to cancel at least one of road noise and engine noise in the first zone if the amount of noise in the first zone is greater than the amount of noise in the second zone;
• selectively drive only at least one second loudspeaker in the second zone to generate the second cancellation field to cancel the at least one of road noise and engine noise in the second zone if the amount of noise in the second zone is greater than the amount of noise in the first zone;
• and
• train a first adaptive filter to reach a first predetermined noise level while driving only the at least one first loudspeaker to provide the first cancellation field and while disabling the at least one second loudspeaker from generating the second cancellation field.
