Abstract
A noise cancelling system for a vehicle includes a microphone, at least one first sensor configured to collect first data related to an element that generates a noise sound, at least one second sensor configured to collect second data related to an element that changes a secondary path of the noise sound, a controller configured to select a secondary path model corresponding to the second data from among a plurality of pre-stored secondary path models, input the first data to a secondary path filter corresponding to the selected secondary path model, and generate an anti-noise signal based on output data of the secondary path filter and error data received from the microphone, and a speaker configured to output an anti-noise sound based on the anti-noise signal.
Claims19
A noise cancelling system for a vehicle, comprising:
- a microphone;
- at least one first sensor configured to collect first data associated with at least one element that generates a noise sound;
- at least one second sensor configured to collect second data associated with at least one element that changes a secondary path of the noise sound;
- a controller configured to:
- select a secondary path model corresponding to the second data from among a plurality of pre-stored secondary path models;
- input the first data to a secondary path filter corresponding to the selected secondary path model;
- and
- generate an anti-noise signal based on output data of the secondary path filter and error data received from the microphone;
- and
- a speaker configured to output an anti-noise sound based on the anti-noise signal.
A method of controlling a noise cancelling system of a vehicle, the method comprising:
- receiving, by a controller, first data associated with at least one element that generates a noise sound;
- receiving, by the controller, second data associated with at least one element that changes a secondary path of the noise sound;
- selecting, by the controller, a secondary path model corresponding to the second data from among a plurality of pre-stored secondary path models;
- inputting, by the controller, the first data to a secondary path filter corresponding to the selected secondary path model;
- generating, by the controller, an anti-noise signal based on output data of the secondary path filter and error data received from the microphone;
- and
- outputting, by the controller, an anti-noise sound based on the anti-noise signal.
