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.

In the method, the transmission ratio of the speed transmission (i_act) is set automatically using stored adjustment characteristic curves, as a function of a variable (FP, tv) which characterizes the engine output, and a variable (v) which characterizes the vehicle speed. The transmission ratio is varied as required by means of a manual intervention by the driver. The transmission ratio of the speed transmission is set as a stepped deviation from a setpoint engine speed (n_eng).
