Method and system for controlling a vehicle coupling

摘要

The method involves operating a coupling (12) with no or less slip during existence of a determined condition in a driving mode. The coupling is operated with an increased slip during falling of a rotational speed of an input shaft of a motor vehicle below a critical rotational speed and approximating another critical rotational speed. The coupling is operated with the high slip and small torque transmission capabilities during falling of the rotational speed of the shaft below the latter critical rotational speed. An independent claim is also included for a system for controlling a coupling arranged between an output shaft of an engine and an input shaft of a motor vehicle.
