Claim 7:
8. A drive train for an electric vehicle, comprising:
a planetary gear set;
a first electric machine coupled to a first input node of the planetary gear set on a first side of an output node of the planetary gear set;
a second electric machine coupled to a second input node of the planetary gear set, the second input node on a second side of the output node, opposite of the first side; and
a controller configured with executable instructions stored on non-transitory memory which, when executed, cause the controller to:
operate the first electric machine at a first speed in a torque control mode;
operate the second electric machine at a second speed in a speed control mode, the second speed selected based on the first speed of the first electric machine, and wherein a first torque generated by the first electric machine and a second torque generated by the second electric machine are summed at the output node of the planetary gear set; and
operate the drive train in a single motor, torque multiplication mode when the first electric machine or the second electric machine is commanded to operate at zero speed.
