Drive train for a motor vehicle

摘要

In a drive train (1) having an engine (18) which is controlled by an engine controller (2) and a transmission (26) which is controlled by a transmission controller (3), an intervention signal (ES) is transferred to the engine controller from the transmission controller via a data link (4). The intervention signal has values by means of which operating states (phases 0-IV) of the drive train (1) are specified during the driving mode of the motor vehicle and during the gear shift operations of the transmission (26).
