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.

Abstract: A hybrid controller unit includes a detection module, a gear-hold module, a gear-skip module, and an optimizing module. The detection module is structured to detect a deceleration event. The gear-hold module is structured to determine whether a certain gear of a transmission should be maintained for a certain period of time in order to optimize power regeneration during the deceleration event. The gear-hold module is also structured to generate a gear-hold request. The gear-skip module is structured to determine whether the transmission should skip a gear in order to optimize power regeneration during the deceleration event. The gear-skip module is also structured to generate a gear-skip request. The optimizing module is structured to receive the gear-hold request and the gear-skip request and generate a transmission command to be sent to a transmission control unit for actuation.

Abstract: A method for controlling aftertreatment regeneration for a system having a hybrid powertrain is described. The method includes determining that an engine aftertreatment regeneration is indicated when a regeneration request index exceeds a first threshold. The method includes determining an acceptable battery usage amount based on a current battery state of charge (SOC) and a minimum battery SOC. The method further includes determining a battery usage amount for an engine aftertreatment regeneration operation. The method includes initiating an engine aftertreatment regeneration when the battery usage amount is less than or equal to the acceptable battery usage amount.
