  1. 1. Numerical Optimal Control of Hybrid Electric Trucks : Exhaust Temperature, NOx Emission and Fuel Consumption

    Master-uppsats, Linköpings universitet/Fordonssystem; Linköpings universitet/Fordonssystem

    Författare :Fredrik Andersson; Hampus Andersson; [2018]
    Nyckelord :Numerical optimal control; HEV; Diesel electric hybrid truck; Exhaust temperature; Emissions; NOx; SCR;

    Sammanfattning : The controls for a parallel hybrid electric truck are optimized using numerical optimal control. Trade-offs between catalyst light-off times, NOx emission and fuel consumption have been investigated for cold starts at two operating points, as well as temperature differences between conventional and hybrid powertrains during WHTC (World Harmonized Transient Cycle).
