Abstract:
A method of controlling a selectable one way clutch operable to selectively couple a shaft to a housing of a transmission includes determining if an electric motor is currently operating, and if the selectable one way clutch is currently engaged to couple the shaft to the housing. It is further determined whether or not wheel torque of at least one wheel is currently being actively managed by at least one vehicle control system. When the electric motor is operating with the selectable one way clutch engaged, and wheel torque of at least one wheel of the hybrid vehicle is currently being actively managed by at least one vehicle control system, then selectable one way clutch is disengaged to release the shaft from the housing and allow rotation of the shaft relative to the housing.
