Abstract
A system and method for controlling a hybrid vehicle having an engine, a traction motor, and an automatic step-ratio transmission having a plurality of selectable discrete gear ratios include operating the electric machine to provide output torque associated with a first operating point selected based on driver demand torque and a current powertrain speed during transient operation, operating the electric machine to provide an output torque associated with a second operating point selected based on the driver demand torque and the current powertrain speed during steady state operation, and controlling the engine torque based on a difference between the driver demand torque and the electric machine torque.
