Abstract
A drive train of a motor vehicle with an internal combustion engine, a torque converter and a transmission, wherein a separation clutch is provided between the internal combustion engine and the torque converter. In order to be able to perform a creeping process at a certain creeping velocity, the separation clutch is operated slipping. This way, the gearing of the startup process can be configured long, even when using a so-called hard torque converter, without having to tolerate a creeping velocity, which is too high.
