ABSTRACT:
A method of power management for a hybrid powertrain system includes the step of determining a storage power from a power flow into or out of an energy storage apparatus. The method also includes the step of determining an actual level of energy stored in the energy storage apparatus, determining a desired level of energy stored in the energy storage apparatus, and determining an energy storage level error from a difference between the desired level of energy stored and the actual level of energy stored. The method further includes the step of determining an engine power change from the energy storage level error and an actual storage power flow, determining an engine power setting from the engine power change, and modifying the engine by the engine power setting.
