Abstract
A diagnostic method for a torsional vibration damper in a drive train of a vehicle may include the steps of providing a drive train having a drive unit (e.g., an internal combustion engine) for generating a driving torque, a drive shaft (e.g., a crankshaft) coupled to the drive unit for transmitting the driving torque to an output shaft, and a torsional vibration damper connected to the drive shaft for damping torsional vibrations of the drive shaft, capturing a reference vibration signal of the drive shaft in a reference state, capturing an operating vibration signal of the drive shaft in an operating state deviating from the reference state, and comparing the reference vibration signal to the operating vibration signal.
