1. A method for operating the drive train of a motor vehicle. 2.1. In a known method, with the friction clutch completely closed, a control device monitors rotational speeds upstream and downstream of the clutch. As soon as slip occurs, the control devices reduces an output torque of an engine for a limited time. The object of the invention is to propose a method, by means of which, while adhering as much as possible to a torque instruction of a vehicle driver, damage to the friction clutch and to further components of the transmission is avoided. 2.2 According to the invention, with the friction clutch slipping, the control device determines an energy quantity dissipated in the friction clutch and/or a temperature of the friction clutch. If the dissipated energy quantity and/or the temperature overshoot limit values, the control device reduces the output torque of the engine. According to a second embodiment, the output torque of the engine is reduced in steps. 2.3 Use in a motor vehicle.
