Beschreibung
Zusammenfassung:	An active noise control method for a vehicle including: acquiring frequency section information corresponding to a current state of the vehicle from a lookup table that has previously stored combination information for each frequency section of a plurality of acceleration sensors for each of state variables of the vehicle; generating a virtual reference signal from reference signals of the plurality of acceleration sensors on the basis of the frequency section information; generating an active noise control signal on the basis of the virtual reference signal and an error signal; and outputting an active noise control sound based on the active noise control signal.
