Method for damping mechanical vibrations in a vehicle

A method of damping mechanical vibrations in a vehicle having a drive train with an internal-combustion engine and an electric driving motor, comprising the acts of:

• conducting a vibration analysis on signals describing a current vibration behavior between the internal-combustion engine and the vehicle body,
• conducting a vibration analysis on signals describing a current vibration behavior between the electric driving motor and the vehicle body;
• using the vibration analyses to determine an interference frequency;
• generating a fault signal that describes the interference frequency;
• supplying the fault signal to each of a plurality of logic modules;
• computing a separate compensation torque to dampen the mechanical vibrations in the vehicle using each logic module, each logic module computing a different compensation torque at a different internal-combustion engine speed that is a harmonic of the supplied interference frequency of the engine;
• adding all computed compensation torques to generate a total compensation torque;
• and
• supplying the total compensation torque to the vehicle via the electric motor.
