ABSTRACT:
When a differential speed determined from the wheel speeds has superimposed thereon a frequency typical of drive train vibrations, a vibration signal is generated. When the vibration signal exceeds a threshold, a torsional moment based on the difference between the engine speed and the differential speed is used to modify activation times of the brake pressure control valves so that the drive train vibrations decay.
