Predictive control techniques for an electrified powertrain of a hybrid electric vehicle (HEV) include maintaining a database of past measured operational parameters of an electrified powertrain during a plurality of past drive cycles of the HEV, monitoring and comparing measured operational parameters of the electrified powertrain during a current drive cycle of the HEV to the past measured operational parameters of the electrified powertrain stored in the database, predicting or estimating operational parameters of the electrified powertrain for a remainder of the current drive cycle of the HEV based on the comparison, and controlling the electrified powertrain during the remainder of the current drive cycle of the HEV based on the predicted/estimated operational parameters of the electrified powertrain including at least controlling recharging of a high voltage (HV) battery system to increase a fuel economy or operational efficiency of the electrified powertrain.
