Abstract

The aim of the invention is to regulate the braking torque in a drive train comprising an internal combustion engine (2) and a gearbox unit (3) which can be coupled to the same, using a regulatable clutch (5). To this end, the power introduced by the wheels into the drive train of the vehicle is transmitted via the regulatable clutch (5), in the overrun condition. The torque which can be transferred via the regulatable hydrodynamic clutch is controlled or regulated in such a way that the drive motor connected to the gearbox unit is operated at a rotational speed nm-soil which is equal to or larger than the idling rotational speed nLeerlauf.
