Abstract
An engine is mechanically coupled to a transmission device, the transmission device operative to transfer mechanical power between the engine and a second power generating device and an output member. A method for controlling the engine includes monitoring an operator demand for power, selecting a preferred engine state, determining a preferred engine torque input to the transmission device when operating in the preferred engine state based upon the operator demand for power, determining constraints on the engine torque input to the transmission device based upon a capacity of the transmission device to react the engine torque input, and commanding operation of the engine to the preferred engine state and commanding the engine torque input to the transmission device based upon the preferred engine torque input and the constraints on the engine torque input.
