Regulating method for rotational speed difference between two coupling half of friction conclusive coupling of drive train of vehicle, involes calculating rotational speed of two coupling half

摘要

The method involves calculating rotational speed of the two coupling half (5A,5B), which are smaller or equal of a pre defined threshold rotational speed for determaination of the actual rotational speed of a friction conclusive coupling (5) in every case of another coupling half (5B). The actual rotational speed of the coupling is provided to determined rotational speed of the later coupling half independently.
