Abstract

A method for controlling a slip of a clutch device of a gearbox of a vehicle includes measuring at least one rotational speed value on a gearbox shaft of the gearbox; determining an active gearbox shaft; determining the angular acceleration on the active gearbox shaft determined, on the basis of the at least one measured rotational speed value; producing a rattling characteristic value on the basis of the angular acceleration determined over at least one time interval; and controlling the slip of the clutch device on the basis of a comparison of the rattling characteristic value produced with at least one rattling threshold value.
