Abstract

A method of controlling and/or regulating the slip of a clutch, for example, a clutch of a transmission, for example, a CVT transmission, is provided, the clutch including a driving element and an output element. The method measures at least one driving rotational speed and at least one output rotational speed for the controlling and/or regulating of the slip of the clutch, at least one driving rotational speed being measured when the clutch is closed, and at least one output rotational speed being measured when the clutch is closed; and the method determines a corrected driving rotational speed and/or a corrected output rotational speed for considering errors in the measured driving rotational speeds and in the measured output rotational speeds, by considering the at least one driving rotational speed measured when the clutch is closed and the at least one output rotational speed measured when the clutch is closed.
