Abstract
Methods and systems are provided for an electric drivetrain. In one example, the electric drivetrain system includes a first and a second electric motor-generator rotationally coupled to a planetary assembly that is rotationally coupled to a drive axle via an output gear. The system further includes a controller that is configured to, during a first operating condition, operate each of the first and second electric motor-generators in a motor mode or a generator mode and hold the output gear at a zero speed.
