Abstract:
1. A drive train comprising: an internal combustion engine; first and second electric drive units; a first power branch that conducts a torque from the internal combustion engine, wherein the first electric drive unit exchanges power with the first power branch in partial operating ranges; a second power branch that is operative at least in partial operating ranges, wherein the second electric drive unit exchanges power with the second power branch in partial operating ranges; and a pick off gear unit having a plurality of transmission elements, by which the power of at least one of the first and second power branches is transferred to an output element; wherein in a first operating position the power branches are coupleable directly to one another so that the power branches share a common drive connection to a single one of the transmission elements of the pick off gear unit; and wherein in a second operating position the power branches are coupleable to one another via the pick off gear unit, the power branches having drive connections to two transmission elements of the pick off gear unit, respectively.
