Abstract
A hybrid powertrain system includes an internal combustion engine, an electric machine coupled to a transmission, a fluid coupling including an impeller and a turbine wherein the impeller is mechanically coupled to a rotatable member of the electric machine and the turbine is mechanically coupled to a rotatable member of the internal combustion engine. The fluid coupling is effective to fluidically couple torque from the electric machine to the internal combustion engine when the impeller and turbine are not mechanically locked.
