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.

The invention relates to an arrangement which permits operating characteristic variables such as the crankshaft rotational speed and the content of exhaust gas components to be determined in the workshop. The sensor is mounted so as to be stationary in the exhaust gas system or is only intermittently mounted in this system. According to one arrangement of the invention, the exhaust gas sensor includes a first device which receives the pressure of the exhaust gas of the engine. In this way, the crankshaft rotational speed can be arrived at. A second device is arranged in the exhaust gas sensor which has an output signal which is a measure for the content of an exhaust gas component. A further embodiment of the arrangement of the invention includes an exhaust gas sensor having a first device which is configured as a fault meter, temperature sensor or as a hot wire flow meter. Other devices can be utilized to detect further variables of the exhaust gas and evaluate the same.
