Method for operating drive train of vehicle, involves coupling drive engine by automated clutch to automatic transmission, where control of drive machine and transmission takes place by control units

摘要

The method involves coupling a drive engine (4) by an automated clutch (8) to an automatic transmission (6). A control of the drive machine and the transmission takes place by control units (3,5). The control unit of the drive machine provides a reserve moment during a starting operation or a switching operation in the transmission. The information is transmitted by a height of reserve moment to the control unit of the transmission. The control unit controls clutch moment transferable by the clutch as a function of the reserve moment, such that clutch moment does not exceed reserve moment. An independent claim is included for an arrangement for operating a drive train of a vehicle.
