Abstract
An active noise control method and system for a vehicle are provided. The active noise control method for a vehicle includes performing active noise control (ANC) to reduce noise introduced from the outside of the vehicle to the inside of the vehicle and received through a microphone, determining whether a level of residual noise of the noise reduced by the ANC is greater than a threshold value, and performing secondary path model re-measurement when an engine of the vehicle is turned off if the level of the residual noise is greater than the threshold value.
Claims12
An active noise control method for a vehicle, comprising:
- performing active noise control (ANC) to reduce noise that is received through a microphone from an outside of the vehicle to an inside of the vehicle;
- determining whether a level of residual noise of the noise reduced by the ANC is greater than a threshold value;
- and
- performing, based on a determination that the level of the residual noise is greater than the threshold value, secondary path model re-measurement when an engine of the vehicle is turned off.
An active noise control system for a vehicle, comprising:
- at least one processor;
- and
- at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:
- performing active noise control (ANC) to reduce noise that is received through a microphone from an outside of the vehicle to an inside of the vehicle,
- determining whether a level of residual noise of the noise reduced by the ANC is greater than a threshold value, and
- performing, based on a determination that the level of the residual noise is greater than the threshold value, secondary path model re-measurement when an engine of the vehicle is turned off.
