Patent ID: 11846330

Abstract:
The present disclosure relates to a method for defining a clutch slipping point position (Xsp) of a clutch in a gearbox comprising an input shaft arranged to be braked by a braking means. The method includes determining if the clutch is dragging when the clutch is fully disengaged. The method includes when it is determined that the clutch is dragging, applying the braking means with a predetermined brake torque (Tb) and so that the input shaft is not rotating; and thereafter: moving the clutch from the fully disengaged position towards an engaged position; determining when the input shaft starts to rotate with a predetermined rotation value indicative of a rotational speed of the input shaft; registering a clutch position (Xb) in which the clutch is positioned when the predetermined rotation value is reached; using a clutch transfer characteristics of the clutch, Tb, and Xb to define the clutch slipping point position (Xsp).
