The invention relates to a process for carrying out an automated clutch actuation of a motor vehicle with a drive engine and a transmission, connected to said drive engine by way of a clutch, in which process the clutch exhibits both an opened and a closed operating position, whereby to introduce unpowered operating phases the clutch is transferred by means of automation into the opened operating position and to introduce powered operating phases it is transferred by means of automation into the closed operating position. To design such a process more reliably and comfortably, the variables, from which a dangerous situation in time or its termination can be concluded with a certain probability, are measured, according to the invention, so that the clutch can be moved into an operating position (opened or closed), which makes it possible to carry out faster the subsequent request of the driver&#x2014;such as an acceleration request or a braking request.

Method for carrying out an automated clutch actuation during non-driven operational phases

For adjusting the beginning of the pump delivery in a timing device of an injection pump of an air-compressing internal combustion engine for the drive of a vehicle, the beginning of pump delivery belonging to the load condition is determined and adjusted by means of an electric control unit on the basis of the operating parameters internal combustion engine rotational speed, control rack displacement and crankshaft position signal. For reducing the noise emission of the internal combustion engine, in case of a change from an internal combustion engine load which exists over a predetermined time period, from a lower load range into an upper load range, the beginning of the pump delivery is initially adjusted by the control unit in the direction of retard and subsequently the beginning of the pump delivery coordinated to the changed load condition is caused to follow-up with time delay.
