2. Method for controlling a powertrain system including an internal combustion engine configured to transfer torque via activation of a clutch to an input member of a hybrid transmission having torque machines configured to transfer torque thereto, the method comprising:
-
commanding a change in activation of the clutch; controlling operations of the torque machines to generate an output torque at an output member of the hybrid transmission responsive to an operator torque request; and coincidentally controlling operation of the engine to achieve the change in activation of the clutch between the engine and the input member of the hybrid transmission. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
