Abstract

A method and arrangement is provided for controlling a motor vehicle drive train equipped with at least one drive motor, a torque converter, an automatic transmission and at least one electronic drive control device. In the drive control device, a function module is implemented for carrying out a creep control. This creep control can be activated independently of a brake actuation, when the actual rotational speed of the driving motor is greater than a defined desired rotational speed of the driving motor, and when the actual rotational speed of the driving motor cannot be reduced because of at least one defined condition as the minimally possible rotational speed of the driving motor.
