摘要：A method and device for a coupling () in a motor vehicle, transmission () areproposed in which the coupling is controlled and regulated during three operational
states via a first regulating circuit (). The regulated quantity corresponds to the actualvalue of a differential rotational speed of the coupling (). The first state corresponds to astarting operation, the second state to the operation with constant ratio and the thirdstate exists when a gear shift under load or a change of ratio from a first to a secondratio step of an automatic transmission () is initiated.
