Integrated energy & emission management for hybrid electric truck with SCR aftertreatment
conference paper
Energy management in hybrid vehicles typically relates to the vehicle powertrain, whereas emission management is associated with the combustion engine and aftertreatment system. To achieve maximum performance in fuel economy and regulated pollutants, the concept of (model-based) Integrated Powertrain Control (IPC) is proposed. Based on results from optimal control and the Equivalent Consumption Minimization Strategy, this paper presents a novel IPC strategy for a series hybrid electric heavy duty vehicle with a SCR (Selective Catalytic Reduction) DeNOx aftertreatment system. This strategy makes use of a control model incorporating the dynamics of both the powertrain components as well as the aftertreatment system. Simulation results demonstrate how IPC can optimize the classical trade-off between operational costs (comprising fuel use and AdBlue dosing) versus the production of tail-pipe NOx emissions.
