A hybrid electric vehicle powertrain.

摘要

A hybrid electric vehicle powertrain is disclosed that has an engine 10, a motor 80, a generator 34 and a battery 90 that define electro-mechanical power flow paths to vehicle traction wheels in both a forward drive operating mode and a reverse drive operating mode. A coupler clutch 54 is operable to distribute reverse driving torque from a power dividing gearset 16 to complement reverse driving torque of the motor 80 when the powertrain is operating in the reverse drive operating mode.
