Abstract
A hybrid electric vehicle (HEV) includes an internal combustion engine, a motor/generator configured to drive the internal combustion engine or be driven by the internal combustion engine to generate electricity to charge a high voltage battery and/or drive one or more electric traction motors, and an exhaust aftertreatment system having a gasoline particulate filter (GPF). A control system includes a controller for monitoring and performing a regeneration operation of the GPF. The controller is programmed to determine the GPF needs to be regenerated, and operate the internal combustion engine in fuel shut-off to generate a flow of air to the GPF to initiate a GPF regeneration.
