Abstract:
1. A power-shiftable transmission of a planetary design for a vehicle, the power-shiftable transmission comprising: a plurality of frictional shifting elements, at least one interlocking shifting element (A, B, C, D, E. F, G) and a plurality of gearwheels which, via the frictional and the at least one interlocking shifting elements (A, B, C, D, E, F, G), are engagable in a power flow to implement a plurality of gear steps, the plurality of gear steps including at least eight forward gear steps, at least two associated shifting elements, of the plurality of frictional and the at least one interlocking shifting elements (A, B, C, D, E, F, G), are engaged for each of the at least eight forward gear steps, at least one frictional shifting element, of the plurality of frictional shifting elements, is engaged for less than three gear steps of the plurality of gear steps, and at least one interlocking shifting element (A, B, C, D, E, F, G) being associated, as a shifting element (B, C, F, G) to be engaged, with a target gear step to be engaged, by way of a supporting gear step during an upshift from a current gear step, wherein, during the upshift to the target gear step to be engaged, the supporting gear step is temporarily engaged so as to facilitate synchronization and engagement of the at least one interlocking shifting element of the target gear step to be engaged.
