Drive train method for operating a motor vehicle's drive train uses a driving motor and an automatic gearwheel gear change box during a gearwheel gear change from a source gear to a target gear

摘要

After undoing a drive train (DT) (10), a driving motor's (11) speed is adjusted to a constant scheduled speed that is preset by a control device (17) for a gearwheel gear change box (GWCB) (15). The scheduled motor speed corresponds to the driving motor's speed directly after undoing the DT either by opening a clutch (14) between the driving motor and the GWCB or by disengaging a source gear.
