    Abstract: A transmission and a method for operating an automated transmission having a main transmission group and at least one splitter group for producing at least six gears. The gear interval at least in a gearshift between the gears with the lowest and second-lowest gear ratios is chosen to be smaller than the gear interval at least between the gears with the highest and the second-highest gear ratios. At least in the gearshift between the gears with the lowest and second-lowest gear ratios, a shifting element in use associated with the splitter group and a shifting element in use associated with the main transmission group are changed. At least in a gearshift between the gears with the highest and the second-highest gear ratios, a shifting element in use associated with the main transmission group is not changed and a shifting element in use associated with the splitter group is changed.

    Abstract: A vehicle transmission with a drive shaft (AW), two transmission input shafts (GE1, GE2), at least one decoupling element (K2, X1), which is assigned to the second transmission input shaft (GE2), a main shaft (HW), an output shaft (AV) and at least three planetary gear sets (PG1, PG2, PG3). A respective subtransmission (TG1, TG2) is assigned to each of the transmission input shafts (GE1, GE2). One of the two subtransmissions (TG1, TG2) includes at least the first planetary gear set (PG1) while the other of the two subtransmissions (TG1, TG2) includes at least the second planetary gear set (PG2). The shafts (AB, AW, GE1, GE2, HW) are or can be operatively connected to the three planetary gear sets such that at least seven forward gears can be shifted to by the two subtransmissions (TG1, TG2). One of these gears can be shifted as a direct gear or another as an overdrive gear.

    Abstract: A powershift transmission with a dual-clutch main transmission and a downstream planetary gearset. The main transmission includes two partial transmissions and corresponding input shafts and clutches and a common output shaft. The downstream transmission has an input shaft which couples, via a third shifting element, the common output shaft and is fixed to a first planetary gearset element. The downstream transmission has an output shaft that is fixed to a second planetary gearset element. A third planetary gearset element couples a housing by way of a fourth shifting element, to obtain a low driving range of the downstream transmission, or, the downstream transmission output shaft by way of a fifth shifting element to obtain a high driving range of the downstream transmission. The common output shaft can couple, via a sixth shifting element, the third planetary gearset element, which can couple, via the fourth shifting element, the transmission housing.

    Abstract: An assembly includes a transmission and an electric machine for a hybrid drive of a motor vehicle, and the transmission is a multi-stage standard transmission with first and second subtransmissions, each of which has a separate input shaft and shares an output shaft. Both input shafts are coupled to the shared output shaft via form locking shift elements of the subtransmissions. The assembly includes a first shiftable clutch which is allocated to a first input shaft such that the internal combustion engine is coupled to the first input shaft via the first shiftable clutch, and a second shiftable clutch which is allocated to the second input shaft such that the electric machine is coupled to the second input shaft via the second shiftable clutch. The electric machine is coupled to the internal combustion engine via a third shiftable clutch, and to the first input shaft via a fourth shiftable clutch.
