Patent ID: 8306710

Claim:
A method for regeneration of a diesel particulate filter for a hybrid power train including a diesel engine and an electric motor/generator where the diesel particulate filter is fluidically connected to pass exhaust gas from the diesel engine, the method comprising the steps of: periodically initiating regeneration of the diesel particulate filter; responsive to initiation of regeneration determining if the load carried by the diesel engine is sufficient to produce exhaust gas having a temperature sufficiently high for a sufficient period of time to clear the diesel particulate filter of particulate matter; and if not; increasing the load on the diesel engine; continuing to match hybrid power train output torque to driver demand torque; and further steps responsive to the electric motor/generator reaching or being at a maximum level of charge of either disabling the electric motor/generator, or converting electrical current from the electric motor/generator into thermal energy and injecting the thermal energy into the diesel particulate filter.
