Abstract
A system and method are disclosed for controlling a power split in a hybrid powertrain having an engine and a motor. According to at least one aspect of the present disclosure, the method includes selecting a displaced fuel consumption value for the engine based on a quantity of available reclaimed energy in a battery, where the displaced fuel consumption value favors using the quantity of available reclaimed energy at relatively high load conditions, operating the engine at a condition based on the displaced fuel consumption value to generate engine power to meet at least a portion of a power demand, and operating the motor to generate motor power sufficient to supply a remaining power demand not met by the engine power. The system includes a controller configured to perform the operations of the method.
