Method for recognizing bad connection of clutch arranged between electrical machine and combustion engine with parallel hybrid drive strand of motor vehicle, involves monitoring control flow of clutch

摘要

The method involves monitoring control flow of a clutch (4). The connection of the clutch is recognized, when the clutch exceeds a given threshold value of the control flow. The connection of the clutch is examined after the recognition, such as the actual difference-rotational speed is between the rotation of an electrical machine (2) and the rotation of a combustion engine (1).
