Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A motor vehicle drive train device, comprising: a multi-group transmission which 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, wherein the motor vehicle drive train device is configured to shift, at least in one transmission gear change operation, the front-mounted group and/or the downstream group into neutral before engaging a tar…
