Abstract: The invention relates to a device for measuring a rotor parameter, including: an incremental material measure, which is connected to a rotor or stator in a rotationally fixed manner and which has increment marks, an increment-measure sensor, which is arranged facing the incremental material measure and which is arranged on the stator if the incremental material measure is connected to the rotor in a rotationally fixed manner and which is arranged on the rotor if the incremental material measure is connected to the stator in a rotationally fixed manner, and an evaluating unit. The device has a timer, which is reset and restarted each time an increment mark passes by the increment-measure sensor. In dependence on a value of the timer, the evaluating unit determines the rotor parameter for an intermediate rotational position of the rotor lying between two rotational positions of the rotor that correspond to two adjacent increment marks that the rotor passes by in succession.

Abstract: A drive train, which has an internal combustion engine with a crankshaft and a parallel shift transmission with two part drive trains, which each have one transmission input shaft. One shaft is formed as a hollow shaft around the other shaft, and a dual clutch, which is received rotatably on the hollow shaft, is connected to the crankshaft and has two friction clutches and two clutch plates each assigned to one clutch and are each connected to one transmission input shaft. Each clutch plate has a torsional vibration damper with a working range which is smaller than a maximum torque of the engine. A build-up of a combined vibration which has an axial vibration of the dual clutch and a rotational vibration of the drive train during an overlap shift operation is prevented by the design of the torsional vibration dampers for a smaller torque.
