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.
