A method for active vibration control of a hybrid electric vehicle may include: determining by a controller whether a driving mode enters an idle region based on a motor speed or an engine speed; selecting a reference angle signal based on position information of a motor or an engine when the driving mode enters the idle region; setting up 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; setting up a reference spectrum according to the engine speed and an engine load; extracting vibration components based on the reference spectrum; summing vibration components according to frequencies and performing inverse FFT; determining an amplitude ratio according to the engine speed and the engine load; and performing active vibration control of each frequency based on the amplitude ratio and motor torque.
