  1. 1. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guanqiao Song; [2020]
    Nyckelord :Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

    Sammanfattning : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. LÄS MER

  3. 2. An evaluation of sustainable designs for trucks : A life cycle analysis

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Kim Jaconelli Palm; [2020]
    Nyckelord :;

    Sammanfattning : The largest carbon footprint in the life cycle of a truck comes from the use phase. However, with new fuels and larger renewable energy share in the electricity mix, both the manufacture and the disposal phase show increasing weight in carbon emission. A truck consists in large part of steel, which in production generates carbon dioxide. LÄS MER

  4. 3. Powertrain dynamic torque reduction using clutch slip control

    Master-uppsats, KTH/Fordonsdynamik; KTH/Farkost och flyg

    Författare :Marcus Engman; Andreas Szilassy; [2014]
    Nyckelord :;

    Sammanfattning : The torque dynamic caused by the firing pulse from diesel engines set high robustness demands for gearboxes and final drives in today’s heavy duty trucks. If these dynamic loads could be eliminated or dampened, the driveline can be built lighter because of the lower demands which in turn would save fuel for the driver and material cost for the manufacturer.

  5. 4. Drivetrain Modelling and Clutch Temperature Estimation in Heavy Duty Trucks

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

    Författare :Johan Thornblad; [2014]
    Nyckelord :Drivetrain; Modelling; Clutch; Temperature; Estimation; EKF;

    Sammanfattning : An existing drivetrain model with clutch temperature dynamics has been used to simulate the behaviour of a heavy duty truck. During the implementation of the model in MATLAB/Simulink modularity and simplicity was greatly emphasized. LÄS MER
