Abstract:
1. A method for operating a drive train ( 1 ) in a motor vehicle with a dual mass flywheel ( 9 ) driven by an internal combustion engine ( 2 ) via a crankshaft ( 3 ) and at least a transmission input shaft ( 5 ) of a transmission ( 6 ) that can be coupled with an output part ( 7 ) of the dual mass flywheel ( 9 ), comprising: effecting a hysteresis-laden damping device ( influencing, using the hysteresis-laden damping device, engine torque output from the internal combustion engine ( constantly determining rotation speeds of the input part and of the output part; and determining in real time depending on a differential angle determined from the rotation speeds between the input part (
