  • Method and control device for operating a drive train
    Patent number: 12158203
    Abstract: A method for operating a motor vehicle drive train having a drive aggregate, an automated group transmission connected between the drive aggregate and a drive output, and a disconnect clutch connected between the drive aggregate and the group transmission. The group transmission has a plurality of sub-transmissions, including a main transmission, a splitter group upstream from the main transmission, and a range group downstream from the main transmission. When the disconnect clutch cannot be shifted to carry out a shifting operation in the group transmission, an emergency shifting program is activated. Shifting from a current gear to a target gear is carried out automatically, as a function of input rotation speed of the group transmission or as a function of rotation speed of the drive aggregate, while the disconnect clutch is closed and where the main transmission and/or the range group participate exclusively, but not the splitter group.
