  • the object of the present invention is to propose an improved method for vibration damping of a torque of a drive train, in particular to propose an alternative to the known methods.
  • this object is achieved by a method according to claim 1, according to which a method for vibration damping of a torque of a drive train is provided, the drive train having an electric motor with a speed sensor and an engine control unit, a damping control device, a device for determining the target torque of the electric motor and at least one Vehicle wheel comprising a speed sensor, wherein the damping control device comprises a first calculation device, a high-pass filter, a controller and a second calculation device, the following method steps being carried out:
  • the controller determining a value for a compensating torque for damping vibrations and outputting the value for a compensating torque for damping vibrations to the second calculation means;
  • V determining a value of a compensated target engine torque from the second calculation means and outputting the value of a compensated target engine torque to the engine controller.
  • the target torque is adjusted so as not to induce any shaft vibration.
  • the in-phase component of the shaft vibrations is removed by modifying the motor's target torque and ensuring that the motor does not induce resonance on the shaft.
  • the vibrations are intended to dampen the vibrations caused by the inertia and stiffness of the powertrain after a sudden change in torque demand by modulating the engine torque.
  • the vibrations should be dampened in a certain frequency range between 10Hz and 30Hz in order to avoid excessive vibrations.
  • a drive train comprises an electric motor with a speed sensor and an engine control unit, a damping control device, a device for determining the target torque of the engine and at least one vehicle wheel with a speed sensor, with a damping control device being provided, comprising a first calculation means, a high-pass filter, a controller and a second calculation means.
