ABSTRACT:
A hybrid electromechanical transmission includes first, second and third planetary gear sets, an input member, an output member, and first and second motor generators. At least one of the gear members in the first planetary gear set is connected to the first motor/generator. At least one of the gear members in the third planetary gear set is connected to the second motor/generator. First and second interconnecting members continuously connect members of the first planetary gear set with members of the second planetary gear set. Five torque-transmitting mechanisms selectively interconnect members of the planetary gear sets with a stationary member or with other members of the planetary gear sets. One of the five torque-transmitting mechanisms is operative to selectively disconnect the second planetary gear set from the third planetary gear set so that the second motor/generator may drive the output member while disconnected from the first motor/generator and the input member.
