Abstract:
The present disclosure relates to an apparatus and a method for active vibration control of a hybrid electric vehicle. Exemplary forms provide a method for active vibration control of a hybrid electric vehicle that may include detecting an engine speed or a motor speed; selecting a reference angle signal based on position information of a motor or an engine; establishing a period of fast Fourier transform (FFT) and performing FFT of the engine speed or the motor speed corresponding to the period of the FFT from the reference angle signal; establishing a reference spectrum according to an engine speed and an engine load; extracting a vibration components to be removed based on information of the reference spectrum; summing vibration components to be removed according to the frequencies and performing inverse FFT; determining an amplitude ratio according to the engine speed and the engine load; determining an adjustable rate such that a speed change amount of the engine is increased as an anti-phase torque is increased; and performing active vibration control of each frequency based on the information of the basic amplitude ratio, the adjustable rate, and the engine torque.

Claim (Index 3):
The apparatus of  claim 2 , wherein the controller is configured to sum the vibration components to be removed according to frequencies, and to generate a reference signal by performing inverse FFT.
