Patent ID: 7963874

Claim:
An electrically variable transmission comprising: an input member to receive power from an engine; an output member; first and second motor/generators; first, second and third planetary gear sets each having first, second and third members, said input and output members each being continuously connected to a different one of said members; a first interconnecting member continuously connecting a member of said first planetary gear set with a member of said second or third planetary gear set that is continuously connected with said second motor/generator; a second and a third interconnecting member each continuously connecting a different respective one of said members of said second planetary gear set with a different respective one of said members of said third planetary gear set; a first torque-transmitting mechanism operable for selectively connecting a member of said first planetary gear set continuously connected with said input member with a member of said second planetary gear set selectively connectable with a stationary member via a second torque-transmitting mechanism; a third torque-transmitting mechanism operable for selectively connecting a member of said second or third planetary gear set not interconnected with any of said other planetary gear sets with said stationary member; said first motor/generator being continuously connected with a member of said first planetary gear set not connected with said input member or with said other planetary gear sets; and wherein said torque-transmitting mechanisms are engagable to provide an input split, electrically variable reverse mode and an electric forward cruise mode.
