Abstract
A method for detecting a change in the operating behaviour of a crank drive of a motor vehicle such as cracks in the crank drive or for detecting bearing wear. The crank drive includes a crankshaft, a pulse generator generating a signal S dependent on the rotational speed of the pulse generator and the distance of the pulse generator away from the sensor device. The method includes steps of detection of a current signal Sof the sensor device during the operation and comparing the current signal Swith a reference signal Sstored in a memory and detecting a change in the operating behaviour of the crank drive such as cracks in the crank drive or bearing wear, from the comparison of the current signal Swith the reference signal S.
