ABSTRACT:
A one-mode, input-split electrically variable transmission is provided with two motor/generators and a torque-transmitting mechanism that is operatively connected to a second member of a first differential gear set and selectively engageable to connect the second member of the first differential gear set with the stationary member, thereby establishing a fixed speed ratio between the input member and the output member of the transmission. Preferably, another torque-transmitting mechanism is also provided to lock any two members of the differential gear set to one another, thereby establishing a second fixed speed ratio between the input member and the output member.
