Claim:
1. 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.
