Abstract:
The present disclosure relates to active vibration control of a hybrid electric vehicle. One form provides a method that may include setting up a period of fast Fourier transform (FFT) and performing FFT of an engine speed or a motor speed corresponding to the period of the FFT from a reference angle signal; setting up a reference spectrum; extracting vibration components to be removed based on information of the reference spectrum; selecting and adding a removal object frequency from the vibration of each frequency and performing inverse FFT; determining a basic amplitude ratio according to the engine speed and the engine load; determining an adjustable rate which decreases an anti-phase torque as a change amount of the engine speed is decreased; 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 5):
The apparatus of  claim 1 , wherein the controller is configured to set up the reference angle signal by dividing by a number (m) of resolver poles based on information of the position of the motor or to set up the reference angle signal between top dead center (TDC) and bottom dead center (BDC) of a number one cylinder or a number four cylinder based on information of the position of the engine.
