Abstract:
Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods provide different ways to transition engine operating conditions between two low engine fuel consumption operating regions that are separated by a higher engine fuel consumption operating region. In one example, engine torque is increased at a higher rate in a fuel economy mode to increase an amount of time an engine operates in one of the two low fuel consumption operating regions.
