Abstract

In a drive train having an engine which is controlled by an engine controller and a transmission which is controlled by a transmission controller, an intervention signal is transferred to the engine controller from the transmission controller via a data link. The intervention signal has values by means of which operating states of the drive train are specified during the driving mode of the motor vehicle and during the gear shift operations of the transmission.
