Supervisory Control for Real-Driving Emission Compliance of Heavy-Duty Vehicles

This paper presents an economic nonlinear MPC based strategy for integrated control of the engine and the exhaust aftertreatment system (EATS) of a heavy-duty powertrain. The objectives of this control strategy are to improve the fuel economy while fulfilling real-driving emission legislation based on work-based-window, as stipulated in the Euro VI emission legislation for heavy-duty vehicles. The strategy is evaluated using a high-fidelity simulation platform including a validated GT-POWER model of a 13 L turbo compound diesel engine and a first principles model of an EATS. Simulation results show that the strategy always fulfills the real-driving emission legislation.
