    • The invention relates to a shifting device of an automated group transmission comprising a primary transmission (HG) and a split group (VG) upstream thereof having at least one common layshaft (6a, 6b), the split group (VG) thereof being designed as a double clutch transmission having two coaxially arranged input shafts (4, 5), each of which can be connected on the input side via an allocated friction clutch (K1, K2) to the drive shaft (2) of a drive motor and on the output side via at least one shiftable input stage (E1, E2; E3, E4) to the layshaft (6a, 6b). In the shifting device (13) according to the invention, each input shaft is allocated a shifting rod (14, 15), each arranged axis-parallel and axially-slidable and each adjustably connected to the shift sleeve of an allocated shift packet via a shift fork and having at least one engagement opening (17a, 17b, 18a, 18b). A shifting shaft (16) is additionally arranged axis-parallel to the shifting rods (14, 15) having at least one shifting finger (19, 20) for engaging in the engagement openings (17a, 17b, 18a, 18b) of the shifting rods (14, 15) and being rotatable by means of a selection positioner around the longitudinal axis thereof (25) and slidable axially (24) by means of a shifting actuator. In addition, the invention relates to a method for shifting control of an automated group transmission thus equipped.
