Abstract

An electronic management system for an automatically adjustable clutch in a power train between a combustion engine and a manually shiftable transmission of a motor vehicle employs a microcontroller which regulates the transmission of torque by the clutch to initially effect a change from a disengaged condition to a condition of initial engagement with a maximal slip whenever the synchronization of the transmission following a manual shifting of the transmission into a different gear ratio takes place at that RPM of an input and/or an output component of the transmission which exceeds a predetermined threshold value, such as that corresponding to the maximum permisible RPM of the engine. The microcontroller varies the slip of the clutch until the RPM of the input and/or output component of the transmission decreases at least to the predetermined threshold value.
