method for control and / or regulation of the schleppmomentes in a powertrain to tax and control system

摘要

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 nSUBm-soil /SUBwhich is equal to or larger than the idling rotational speed nSUBLeerlauf/SUB.
