摘要： An electrically-variable transmission (114) is provided with first and second motor/generators (180,182) and three planetary gear assemblies (120,130,140). At least one of the planetary gear assemblies (120,130,140) is a planetary gear assembly having multiple planetary gear sets. As a result, the gears for the planetary gear assembly can be represented on multiple radial planes. Each of the planetary gear assemblies (120,130,140) has continuous interconnections, and selective connections via a plurality of torque-transmitting mechanisms, that provide three forward electrically-variable modes. Preferably, the planetary gear assemblies (120,130,140) are connected to one another in such a manner as to allow shifting between one of the electrically-variable modes to occur at a point offset from a mechanical power flow of the transmission (114). This decreases the maximum power output required from the motor/generators (180,182).
