Abstract
A multi-mode hybrid transmission including a selectable one-way clutch and first and second torque machines transitions to operating in a target continuously variable mode including applying a selectable one-way clutch and controlling input torque and motor torques of the first and second torque machines using a second kinematic relationship. A multi-step process is executed to transition the first clutch to a deactivated state, transition the second selectable one-way clutch to the applied state, and transition to using the second kinematic relationship to achieve a preferred output torque.
