Four-mode hybrid transmission
A hybrid transmission includes an input member and an output member. The transmission includes a first and a second motor/generator, and a first, second, and third planetary gear set. The input member is continuously connected for common rotation with a member of the first planetary gear set. The output member is continuously connected for common rotation with a member of the third planetary gear set. An interconnecting member is continuously connected for common rotation with a member of each of the first, second, and third planetary gear sets. A plurality of torque-transmitting mechanisms includes a torque-transmitting mechanism that is selectively engageable to connect the interconnecting member to another member of the third planetary gear set. The motor/generators and the torque-transmitting mechanisms are selectively engageable in different combinations to provide four electric-only operating modes.
