摘要：
A method of controlling an automated variable-speed transmission in a drivetrain of a motor vehicle having all-wheel drive in which, during driving operation under difficult ground conditions, measures are provided for suppression of the automatic shift processes. To reliably prevent undesired automatic shift processes when the vehicle is in an all-wheel drive mode on difficult terrain, particularly also in combination with active differential locks, currently active traction-related mechanisms are evaluated by a plausibility check taking into account detection of wheel slippage, and the measures for suppressing automatic shift processes are carried out as a function of the evaluation.
