Coherence based dynamic stability control system

A method for performing dynamic stability control for a vehicle audio system, comprising:

• controlling a transducer to output a noise cancellation signal based on at least one default parameter;
• receiving at least one reference signal and feedback signal;
• determining a coherence between the reference signal and feedback signal;
• determining whether the coherence exceeds a predefined coherence threshold;
• generating at least one updated parameter by dynamically adjusting the at least one default parameter;
• and
• providing an updated noise cancellation signal based on the at least one updated parameter in response to the coherence failing to exceed the predefined coherence threshold.

A coherence based dynamic stability control system for a vehicle audio system, comprising:

• a transducer, and
• a processor coupled to the transducer, the processor programmed to:
• control the transducer to output a noise cancellation signal based on at least on default parameter;
• receive at least two signals;
• determine a coherence between the two signals;
• determine whether the coherence exceeds a predefined coherence threshold;
• generate at least one updated parameter by dynamically adjusting the at least one default parameter;
• and
• providing an updated noise cancellation signal based on the at least one updated parameter in response to the coherence failing to exceed the predefined coherence threshold.
