Abstract
An arrangement for the controlled engagement and disengagement of a clutch in the transmission of a motor vehicle drive system includes an engine and an automatic transmission which can be activated electro-hydraulically. In order to avoid 'stationary-state shaking', a preselected value for the clutch slip torque is determined as a function of a prehistory of limited duration in the form of an evaluation of the speed profile of the motor vehicle in the immediate past.
