Abstract
Systems and methods are provided for dual electric motor driveline control. In one example, an assembly comprises: a first electric motor directly coupled to a first output shaft, a second electric motor coaxially aligned with the first electric motor, a planetary gear set having a carrier connected to the first output shaft and the first electric motor, a ring gear connected to ground, and a sun gear connected to a second shaft, a first clutch for selectively coupling the second electric motor to the first electric motor via the carrier, and a second clutch for selectively coupling the second electric motor to the second shaft.

An assembly comprising:
- a first electric motor directly coupled to a first output shaft;
- a second electric motor coaxially aligned with the first electric motor;
- a planetary gear set connected to the first output shaft and the first electric motor, and to a second shaft;
- a first clutch for selectively coupling the second electric motor to the first electric motor;
- a second clutch for selectively coupling the second electric motor to the second shaft;
- and
- an axle coupled to the first output shaft, wherein the first clutch and the second clutch selectively couple the first electric motor and the second electric motor to the axle via the first output shaft.
An assembly comprising:
