Another element (E2, 22E2a, 22E2b) of one of the planetary gear sets (P1, 2P3, 2P5) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS, 2ZSa, 2ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW1) can be brought into a fixed rotational speed relationship with respect to each other.Type: GrantFiled: December 5, 2018Date of Patent: February 22, 2022Assignee: ZF FRIEDRICHSHAFEN AGInventors: Martin Brehmer, Stefan Beck, Anton Fritzer, Suryanto Hendrawan, Matthias Horn, Johannes Kaltenbach, Raffael Kuberczyk, Jens Moraw, Gerhard Niederbrucker, Martin Rattay, Matthias Reisch, Wolfgang Rieger, Thomas Rosemeier, Lara Ruth Turner, Bernd Unseld, Viktor Warth, Michael Wechs, Peter Ziemer, Oliver Bayer
