PURPOSE: An active vibration control device of a vehicle is provided to reduce vibration of a vehicle body and indoor noise by controlling exciting force of a vibration reducing control system generating several components of frequency at the same time. CONSTITUTION: An active vibration control device includes a vibration reducing control system(110); a dynamic absorber(120) and a controller(130) to intercept vibration of specific frequency. The vibration reducing control system is mounted to a vehicle to generate exciting force. The dynamic absorber is combined to the vibration reducing control system as an electromagnetic system. The dynamic absorber adds controlling force to the vibration reducing control system to offset exciting force by a driving control signal from the outside. The controller supplies the driving control signal to the dynamic absorber to adjust controlling force. Therefore, several components of frequency are controlled actively.
