Abstract:
A hybrid powertrain includes a plurality of torque generative devices, a transmission input shaft, and a planetary gear set connecting the torque generative devices to the transmission input shaft. A method to control the powertrain includes monitoring a desired configuration of the powertrain and selectively grounding a gear of the planetary gear set with a selectable one way clutch based upon the desired configuration of the powertrain.
