Hybrid powertrain control techniques include determining whether a regeneration event of a gasoline particulate filter (GPF) is necessary using a GPF loading model, commanding a full cylinder deactivation system to temporarily disable all of the cylinders of the engine instead of performing a deceleration fuel shutoff (DFSO) event of the engine and disabling fueling to the engine when the GPF regeneration event is not necessary, commanding the full cylinder deactivation system to keep all of the cylinders of the engine open and disabling fueling to the engine to perform the DFSO event when the GPF regeneration event is necessary, and controlling an electric propulsion motor to supply a requested drive torque, wherein keeping all of the cylinders of the engine open to perform the DFSO of the engine mitigates or eliminates insufficient regeneration of the GPF to thereby increase or extend its useful life.
