Abstract
A method for controlling operation of a hybrid powertrain includes monitoring input speed from the engine to the hybrid transmission, calculating an input speed error between the monitored input speed and a preferred input speed, monitoring operating parameters associated with a plurality of torque actuators wherein the torque actuators include the internal combustion engine, the electric torque machine and the output member, selecting one of the torque actuators, and modifying a state of a control parameter associated with the selected one of the torque actuators in response to the input speed error.
