Claim 11:
12. A method for operating the motor vehicle drive train (12) of claim 8, comprising:
setting the first electric prime mover (14) into rotation (S10) in a first direction of rotation;
setting the second electric prime mover (16) into rotation (S12) in a second direction of rotation opposite the first direction of rotation, rotational speeds of the first and second electric prime movers corresponding to a transmission ratio of the planetary gear set (22) such that the planet gear carrier is at rest; and
changing the rotational speed (S14) of one of the first and second electric prime movers (14, 16) such that a start from standstill is implementable by the first and second electric prime movers (14, 16),
wherein a rotational speed of the first electric prime mover (14) is greater than one hundred revolutions per minute at the start from standstill, and a rotational speed of the second electric prime mover (16) is greater than one hundred revolutions per minute at the start from standstill.
