Abstract

The invention concerns a procedure and a control apparatus for the control of a drivetrain, which comprises at least one automatic clutch, at least one automatic shifting transmission, one control apparatus for the control of the at least one automatic clutch and of at least one automatic shifting transmission as well as at least two transmission idling positions in the drivetrain. In order to avoid dangerous situations, which could arise from an improper automatic input of a neutral position of a transmission and a thereto connected automatic closure of the clutch. The proposal is, that the control apparatus, by way of the shifting of an automatized shifting transmission into a neutral position, to at least two transmission idling positions, the neutral position is put into action.
