Abstract:
1. A method for controlling an automated multi-step variable-speed transmission which, within a drivetrain of a motor vehicle, is connected to a drive engine, on an input side via at least one controllable friction clutch, and to wheels of a driven axle, on an output side axle via an axle drive, such that when the vehicle is at rest, the drive engine is running and the drivetrain is disengaged, rolling of the motor vehicle is either prevented or at least restricted by a shift operation in the multi-step variable-speed transmission, the method comprising the steps of: activating a safety function, when the multi-step variable-speed transmission is in a neutral position (G detecting, with sensors, actuation of a shift operation element, an accelerator pedal and a brake pedal and a current rolling speed; and disengaging the friction clutch (x
