Abstract: Different control strategies for a diesel parallel hybrid passenger car were evaluated through numerical simulations. Two different control strategies were analysed: the first focused on fuel consumption minimisation, the second on NOx emissions cuts. Each of these goals was addressed through two different methodologies, the first based on a group of heuristic laws, the second focused on the instantaneous minimisation of a cost function that takes into account both the fuel and battery energies. A first assessment of the potential of a diesel hybrid passenger car as far as fuel consumption and NOx emissions reductions are concerned was obtained.

Keywords: hybrid electric vehicles; diesel parallel HEVs; fuel consumption minimisation; NOx emissions; emissions reduction; CO2 emissions; carbon emissions; carbon dioxide; control strategy; battery energy; nitrogen oxides.
