Use of selectable one-way clutch in hybrid powertrain
A powertrain includes a plurality of torque generative devices and a transmission having an output shaft, a plurality of planetary gear sets connecting the torque generative devices to the output shaft, and a selectable one-way clutch connected to a first of the planetary gear sets. A method to control the powertrain includes monitoring a desired transmission setting selection comprising one of a low range continuously variable gear mode, a high range continuously variable gear mode, and a fixed gear mode, determining a desired state for the selectable one-way clutch based upon the desired transmission setting selection, and actuating the selectable one-way clutch to effect the desired state for the selectable one-way clutch.
