Abstract
Apparatuses, methods and systems for hybrid powertrain control are disclosed. Certain example embodiments control an internal combustion engine and a motor/generator of a hybrid electric powertrain. Example controls may determine a total output demanded of a powertrain based at least in part upon an operator input, a battery output target based upon a battery state of charge and independent of the operator input, and an engine output target based upon the total output demanded and the battery output target. Such example controls may further determine a constrained engine output target, a modified battery output target based upon the total output demanded and the constrained engine output target, and a constrained battery output target based upon the modified battery output target and a battery constraint. Further embodiments, forms, objects, features, advantages, aspects, and benefits shall become apparent from the following description and figures.
