Abstract
The method for regeneration of a diesel particulate filter of a vehicle equipped with a hybrid engine, wherein the temperature of the exhaust exiting the diesel engine is increased above a predetermined level by increasing load thereon, through optimization of interaction between the diesel particulate filter aftertreatment system and the hybrid engine control through messaging via a communication bus is disclosed. The load on the engine may be increased with or without the assistance of the electric motor/generator of the hybrid engine, and will not affect required acceleration/deceleration of the vehicle.
