System and method for intelligent adjustment for filter(s) for road noise cancellation

A computer-program product embodied in a non-transitory computer read-able medium that is programmed for performing active noise cancellation in a vehicle, the computer-program product comprising instructions for:

• controlling a loudspeaker to generate anti-noise to cancel undesired noise in the vehicle receiving one or more reference signals from one or more accelerometers, each reference signal includes a frequency that is indicative of a force acting on a portion of the vehicle;
• comparing the frequency to a predetermined frequency threshold;
• controlling a first filter to filter to the frequency of the reference signal after comparing the frequency to the predetermined frequency threshold;
• and
• transmitting a filtered reference signal to an adaptive filter to generate the anti-noise without influence of the frequency of the reference signal.
