The transmission (1) comprises a main transmission (HG) comprising two parallel partial transmissions with at least one countershaft (VW), an output shaft (3), and two planetary transmissions (PG1, PG2) each comprising a carrier (ST1, ST2), sun gear (SR1, SR2) and ring gear (HR1, HR2). Each partial transmission has a transmission input shaft (4, 5), with a hollow first input shaft (4) and the solid second input shaft (5). The first planetary transmission (PG1) connects as a range group to the main transmission (HG). The main transmission (HG) comprises first (R1), second (R2), third (R3), fourth (R4) and fifth gear planes (R5) and first (S1), second (S2), third (S3) and fourth shift elements (S4). Synchronization of the countershaft speed to a target speed, in direct gear, is performed via speed control of the electric machine (2).

Abstract: A group transmission of a motor vehicle having a main transmission and a downstream range group. The range group has two gear steps for different speed ranges and a reversing step for reverse driving. The range group has two planetary gearsets, each with a planet carrier, a sun and ring gears. To engage a driving range for lower speeds, the sun gear of the second gearset and the ring gear of the first gearset are locked to the housing by a first clutch. To engage a driving range for higher speeds, two respective elements of the two gearsets can be connected to one another, in a rotationally fixed manner, by a second clutch. To engage a reversing driving range, the planet carrier of the first gearset and the ring gear of the second gearset are locked relative to the housing by a third clutch.
