of a transmission that can be coupled with an output part of the dual mass flywheel between the input part and output part a hysteresis laden damping device is effective which influences engine torque output from the internal combustion engine and load torque transmitted to at least a transmission input shaft through the hysteresis characteristic to eliminate the disturbances caused by the dual mass flywheel a state model constantly determines rotation speeds of the input part and of the output part and depending on a differential angle determined from the rotation speeds and from the characteristic numbers of the damping device a characteristic disturbance torque for influencing at least the load torque is determined in real time application_number US 76735010 A description fig1 shows the schematically depicted drive train 1 with the internal combustion engine 2 and the input part 4 connected with the crankshaft 3 of the internal combustion engine 2 the output part 7 connected with the transmission input shaft 5 of the transmission 6 and the damping device 8 of the dual mass flywheel 9 interposed in between because of the damping device 8 equipped by different friction control devices 13 and energy accumulators like arc springs 12.
