Samenvatting

Energy management in hybrid vehicles typicallyrelates to the vehicle powertrain, whereas emission managementis associated with the combustion engine and aftertreatmentsystem. To achieve maximum performance in fuel economy andregulated pollutants, the concept of (model-based) IntegratedPowertrain Control (IPC) is proposed.Based on results from optimal control and the EquivalentConsumption Minimization Strategy, this paper presents a novelIPC strategy for a series hybrid electric heavy duty vehicle witha SCR (Selective Catalytic Reduction) DeNOx aftertreatmentsystem. This strategy makes use of a control model incorporatingthe dynamics of both the powertrain components as well as theaftertreatment system.Simulation results demonstrate how IPC can optimize theclassical trade-off between operational costs (comprising fueluse and AdBlue dosing) versus the production of tail-pipe NOxemissions.
