Abstract

A method for actuating a continuously variable clutch such that the torque to be transmitted by the clutch is continuously adjusted either electromechanically via an electromotive drive, hydraulically via a pressure actuator, or electromagnetically via an electromagnetic actuator. The torque transmitted by the clutch is adjusted by utilizing a position-dependent clutch torque specification.
