Abstract:
The present invention relates to a vibration control method and apparatus of a power train in a vehicle for reducing the vibrations in a power train when driving on a protruded portion of a road surface using a motor torque control. The apparatus comprises a processor configured to determine the generation of vibrations in a power train as the vehicle passes on the protruded portions of the road surface; and calculate a compensation torque for a vibration reduction of the power train when vibrations occur in the power train as the vehicle passes on the protruded portions of the road surface.
