Abstract

A drive train arrangement for a motor vehicle driven by an internal combustion engine. The engine output or torque of the internal combustion engine (1) is controllable by means of an engine output control (11) via a user-operated accelerator pedal (15). A friction-gearshift clutch (3) is arranged in the torque transmission path of the internal combustion engine (1). To allow the friction-gearshift clutch (3) to be designed for reduced transmission reliability, a slip control (39) reduces the engine output or torque of the internal combustion engine (1) for a time-limited period via the engine output control (11) when the friction-gearshift clutch (3) slips in its fully engaged state. To this end, the slip control (39) responds to a clutch position sensor (41) that detects the engagement position of the friction-gearshift clutch (3), and to speed sensors (43, 45) that detect the input and output speeds of the friction-gearshift clutch (3).
