  • Motor vehicle drive train device comprising a multi-group transmission and shifting method for a multi-group transmission
    Patent number: 9103440
    Abstract: A motor vehicle drive train device has a multi-group transmission that includes a main group, a front-mounted group upstream from the main group, and/or a downstream group downstream from the main group, and a control/regulation unit. The motor vehicle drive train device is provided for shifting, at least in one transmission gear change operation, the front-mounted group and/or the downstream group into neutral before engaging a target gear in the main group. The control/regulation unit is provided for shifting the front-mounted group and/or the downstream group into neutral in the transmission gear change operation only after at least partial synchronization of the main group.

  • Motor Vehicle Drive Train Device Comprising a Multi-Group Transmission
    Publication number: 20150027254
    Abstract: A motor vehicle drive train device includes a multi-group transmission with a main group providing at least one forward transmission gear and at least one reverse transmission gear, and a downstream group downstream from the main group. The device also includes a control and/or regulation unit having a gear change function for shifting the main group at least in one transmission gear change operation in order to engage a transmission gear opposite to the current direction of travel. The control and/or regulation unit has a synchronization function which is provided for shifting the downstream group in order to engage the transmission gear opposite to the current direction of travel.
