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.
