Abstract
A method for determining output torque limits of a powertrain including an electrically variable transmission relies upon a model of the electrically variable transmission. Transmission operating space is defined by combined electric machine torque constraints and engine torque constraints. Output torque limits are determined at the limits of the transmission operating space.
