Claim 16:
17. A method for operating a drive train of an electric vehicle, comprising:
summing a first torque output of a first motor of the drive train and a second torque output of a second motor of the drive train onto an output node of a planetary gear set coupled to each of the first motor and the second motor;
responsive to an increase in torque demand,
operating the drive train in a single motor mode with torque multiplication by commanding operation of one of the first motor and the second motor at zero speed; and

responsive to a decrease in torque demand,
operating the drive train at a pseudo mechanical point to reduce consumption of electrical energy and to reduce mechanical losses at one of the first motor and the second motor.
