Abstract:
A method for damping mechanical vibrations is provided, in particular torsion vibrations, in a vehicle that has a drive train comprising a combustion engine and an electrical drive motor, wherein a signal describing the current vibration behavior of at least one vehicle component is subjected to a vibration analysis, and at at least one interference frequency contained in the signal, a compensation torque counteracting said interference frequency is generated by the electric drive motor.
