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;
- and
- a second clutch for selectively coupling the second electric motor to the second shaft.
An assembly comprising:
- a common housing;
- a first electric motor driving a first output shaft;
- a second electric motor driving a second output shaft, the second electric motor coaxially aligned with the first electric motor;
- and
- a clutch for selectively coupling the first electric motor and the second electric motor
- wherein the first electric motor and the second electric motor are enclosed in the common housing.
An assembly comprising;
- a common housing;
- a first electric motor selectively coupled to a first output shaft;
- a second electric motor coaxially aligned with the first electric motor, the second electric motor coupled to a second output shaft;
- a first clutch for selectively coupling the first electric motor with the first output shaft;
- and
- a second clutch for selectively coupling the first electric motor to the second output shaft
- wherein the first electric motor and the second electric motor are enclosed in the common housing.
