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 4):
The apparatus of  claim 3 , wherein the controller is configured to determine an amplitude ratio according to an engine speed and an engine load, and to perform active vibration control of each frequency by reflecting the amplitude ratio and an engine torque.
