| 摘要 | The present disclosure provides an apparatus and a method for active vibration control of a hybrid electric vehicle. In particular, the method may include: detecting an engine speed or a motor speed; selecting a reference angle signal based on the detected; setting up a period of a fast Fourier transform (FFT) and performing FFT of the engine speed or the motor speed for the period of the FFT from the reference angle signal; setting up a reference spectrum; extracting vibration components based on the reference spectrum; summing vibration components to be removed based on the frequencies and performing inverse FFT; determining a basic amplitude ratio based on the engine speed and an engine load and an adjustable ratio based on a SOC; and performing active vibration control of each frequency based on the the basic amplitude ratio, the adjustable ratio and the engine torque. | ||||||
