Clutch monitoring method for drive system in vehicle, involves comparing damage with damage threshold, and emitting signal when damage reaches damage threshold, where emitted signal is acoustic or visual signal

摘要

The method involves monitoring control of an actuation of a clutch in a sense of closing. A number of rotary speed differences between a clutch input and a clutch output at a time point are determined, during an occurrence of a control delay. The clutch is operated again in the sense of closing. The rotary speed differences are summed, and a damage of the clutch is determined from the rotary speed difference. The damage is compared with a damage threshold, and a signal is emitted when the damage reaches the damage threshold, where the emitted signal is an acoustic or visual signal.
