Vehicle and method of controlling the same

1. 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 first element that generates a noise sound;

at least one second sensor configured to collect second data associated with at least one second element that changes a secondary path of the noise sound, wherein the second data includes at least temperature data, humidity data, and occupant information related to a driving environment of the vehicle;

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.

2. The noise cancelling system of claim 1 , wherein:

the at least one first sensor includes at least one of: a vibration sensor and an engine revolutions per minute (RPM) sensor, and

the at least one second sensor includes at least one of: a temperature sensor, a humidity sensor, and a seat sensor.

3. The noise cancelling system of claim 2 , wherein the controller is further configured to:

select the secondary path model corresponding to the second data based on at least one of: temperature, humidity, number of occupants, and position of each occupant.

4. The noise cancelling system of claim 2 , wherein the plurality of secondary path models are pre-defined based on at least one of: temperature, humidity, number of occupants, and position of each occupant.

5. The noise cancelling system of claim 1 , wherein the controller is further configured to:

generate the anti-noise signal by inputting the first data into an anti-noise signal generation filter.

6. The noise cancelling system of claim 5 , wherein the controller is further configured to:

correct a transfer function of the anti-noise signal generation filter based on the output data of the secondary path filter and the error data received from the microphone.

7. The noise cancelling system of claim 1 , wherein the controller is further configured to:

store a lookup table in which the second data and the plurality of secondary path models are matched.

8. The noise cancelling system of claim 7 , further comprising a communicator configured to:

receive update data for updating the lookup table from a server.

9. The noise cancelling system of claim 1 , further comprising a user interface configured to receive a user input for stopping or activating the output of the anti-noise sound.

10. The noise cancelling system of claim 1 , further comprising the vehicle.

11. 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 first element that generates a noise sound;

receiving, by the controller, second data associated with at least one second element that changes a secondary path of the noise sound, wherein the second data includes at least temperature data, humidity data, and occupant information related to a driving environment of the vehicle;

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.

12. The method of claim 11 , wherein

the first data is obtained by at least one of: a vibration sensor and an engine revolutions per minute (RPM) sensor, and

the second data is obtained by at least one of: a temperature sensor, a humidity sensor, and a seat sensor.

13. The method of claim 12 , wherein selecting the secondary path model further comprises:

selecting, by the controller, the secondary path model corresponding to the second data based on at least one of: temperature, humidity, number of occupants, and position of each occupant.

14. The method of claim 12 , wherein the plurality of secondary path models are pre-defined based on at least one of: temperature, humidity, number of occupants, and position of each occupant.

15. The method of claim 11 , wherein generating the anti-noise signal further comprises:

generating, by the controller, the anti-noise signal by inputting the first data into an anti-noise signal generation filter.

16. The method of claim 15 , wherein generating the anti-noise signal further comprises:

correcting, by the controller, a transfer function of the anti-noise signal generation filter based on the output data of the secondary path filter and the error data collected from the microphone.

17. The method of claim 11 , wherein the pre-stored plurality of secondary path models is included in a lookup table in which the second data and the plurality of secondary path models are matched.

18. The method of claim 17 , further comprising receiving, by the controller, update data for updating the lookup table from a server.

19. The method of claim 11 , further comprising receiving, by the controller, a user input for stopping or activating the output of the anti-noise sound.
