  "textContent": "In speed ratio control apparatus and method for a hybrid transmission, an integrated controller calculates a speed ratio manipulated variable (Ti_ref) in accordance with a deviation (Err) between a speed ratio representative command value ( omega i_ref) and a speed ratio representative actually measured value ( omega i_act). Then the controller calculates a speed ratio purpose component command value (dTe,dT1,dT2) for each drivingly input element torque which is drivingly inputted to a differential mechanism of the hybrid transmission according to the calculated speed ratio manipulated variable (Ti_ref), an acceleration ratio of each drivingly input element in a shift motion, and an inertia of each drivingly input element in the shift motion. Then, the controller outputs each calculated speed ratio purpose component command value (dTe,dT1,dT2) to a torque actuator (3) of the corresponding drivingly input element.",
