  1. 1. An efficient deep reinforcement learning approach to the energy management for a parallel hybrid electric vehicle

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mingwei Liu; [2023]
    Nyckelord :HEV; EMS; Deep Reinforcement Learning; Learning Efficiency; Fuel Efficiency; HEV; EMS; Djup Förstärkningsinlärning; Inlärningseffektivitet; Bränsleeffektivitet;

    Sammanfattning : In contemporary world, the global energy crisis and raise of greenhouse gas concentration in atmosphere necessitate the energy conservation and emission reduction. Hybrid electric vehicles (HEVs) can achieve great promise in reducing fuel consumption and greenhouse gas emissions by appropriate energy management strategies (EMSs). LÄS MER

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

    Master-uppsats, 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).

  4. 3. Modeling and Control of a Parallel HEV Powertrain with Focus on the Clutch

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

    Författare :Mahdi Morsali; [2015]
    Nyckelord :parallel hybrid electric vehicles; clutch modeling; driveline modeling; torsional vibrations; slipping clutch; energy management; optimization;

    Sammanfattning : Nowadays, the increasing amount of greenhouse gases and diminishing of the existing petroleum minerals for future generations, has led the automotive companies to think of producing vehicles with less emissions and fuel consumption. For this purpose, Hybrid Electric Vehicles (HEVs) have emerged in the recent decades. LÄS MER

    Nyckelord :MPC; Model Predictive Control; Plug-In HEV; Quadratic Programming; Hildreths Procedure; Series-Parallel HEV; Split HEV;

    Sammanfattning : The automotive industry is required to deal with increasingly stringent legislationfor greenhouse gases. Hybrid Electric Vehicles, HEV, are gaining acceptance as thefuture path of lower emissions and fuel consumption. LÄS MER

  7. 5. Hybrid Electric & Hydraulic Drivers

    Master-uppsats, Fluida och mekatroniska system

    Författare :Mohammadreza Sadeghi; Ali Mohammed Fahimi Rezaii; [2010]
    Nyckelord :;

    Sammanfattning : The environmental impact of fossil fuel consumption has been a significant issue over the last decade. Mainly because of public awareness, increased fuel cost and stricter legislation. Today’s technological improvements have reduced fuel consumption and also emission of vehicles considerably. LÄS MER
