Abstract: A drive train controller of a motor vehicle has an engine controller for controlling the variables that influence the torque of the engine. The drive train controller also includes a transmission controller for controlling the gear shift operations of the automatic transmission. The transmission controller includes a detection circuit for determining the respective driving situation of the motor vehicle. The transmission controller changes the transmission ratio in a manner that is adaptively matched to the dynamics of the determined driving situation and/or the driver characteristics.

Abstract: A motor vehicle drive and a method for controlling a motor vehicle drive in which control signals, by reference to which a set position is set, are transmitted from a superordinate controller to a subordinate clutch position controller. An actual position signal is transmitted from the position controller to the controller. A feedback message is transmitted from the controller to the position controller via an efficient interface, and the controlling quality is thus optimized by the position controller in accordance with the respective travel situation.
