Abstract: A powertrain system includes an internal combustion engine, at least one electric machine and an electro-mechanical transmission operative to transmit torque to a drive line. A method for controlling the powertrain system includes executing an engagement strategy of a one-way clutch device only having capacity in a first direction. The engagement strategy includes modeling a capacity of the one-way clutch device in accordance with a loading step change profile until a first capacity limit of the one-way clutch device is achieved. A continuous reactive load is applied to the one-way clutch device in the first direction to maintain engagement and inhibit lash of the one-way clutch device.
