ABSTRACT:
A system and method for managing inertial torque reaction of a powertrain include a selectively engageable counter-rotating component to reduce or eliminate torque reaction on stationary powertrain structure. Selectively engageable counter-rotating inertia may be provided by a simple inertial mass or by an electrical machine functioning as an integral starter/generator (ISG) to provide vehicle launch assist, regenerative braking of the vehicle, and engine cranking. Embodiments include gear-driven, chain-driven, and belt-driven counter-rotating inertias selectively coupled for counter-rotation relative to the crankshaft by a clutch, a belt-driven pulley assembly, or chain-driven intermediate shaft assembly with a hydraulically actuated coupling pin.
