  1. 1. Development of an electric driveline model for multiscale road-cargo simulations

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Runzhe Wu; [2022]
    Nyckelord :System Engineering; AnyLogic Traffic Simulation; Simulink Simulation; Driveline Model Building; C Program Execution; Systemteknik; AnyLogic Trafiksimulering; Simulink Simulering; Drivelinemodell; C Programexekvering;

    Sammanfattning : Currently, the road cargo system with low or zero CO2 emission is under rapid development. Heavy-duty trucks with electrified driveline systems will be the workhorse of future freight. LÄS MER

  3. 2. Framtagande av lutningsföreteelse för ruttoptimering av bränsleförbrukning

    Kandidat-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Patrik Svalling; Lukas Frogner; [2022]
    Nyckelord :Road grade; Fuel Consumption in slopes; NVDB; How to measure ground slope; Impact of road slope on fuel consumption; Route optimization with slope; Fuel consumption; Väglutning; Bränsleförbrukning i backar; NVDB; Beräkning av väglutning; Väglutningens påverkan på bränsleförbrukning; Ruttoptimering med lutning; Bränsleförbrukning;

    Sammanfattning : NVDB contains information of Sweden’s roads and a large number of properties concerning them. This information is provided as open data and is commonly usedin routing. For an optimal route optimization, several attributes are needed based on the road properties. At the time that this report was written, there was no attribute for slopes. LÄS MER

  4. 3. Tyre Performance Estimation during Normal Driving

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Marcus Grip; [2021]
    Nyckelord :tyre performance; tread wear; tyre wear; online estimation; friction performance; velocity performance; friction potential; longitudinal stiffness; tyre stiffness;

    Sammanfattning : Driving with tyres not appropriate for the actual conditions can not only lead to accidents related to the tyres, but also cause detrimental effects on the environment via emission of rubber particles if the driving conditions are causing an unexpectedly high amount of tread wear. Estimating tyre performance in an online setting is therefore of interest, and the feasibility to estimate friction performance, velocity performance, and tread wear utilizing available information from the automotive grade sensors is investigated in this thesis.

  5. 4. Styrdokument som verktyg för att öka trafiksäkerheten

    Master-uppsats, KTH/Urbana och regionala studier

    Författare :Hanna Jarlegård; Bastien Lacombe; [2021]
    Nyckelord :trafiksäkerhet; styrdokument; Euro NCAP; säkerhetsavtryck; hållbarhet;

    Sammanfattning : Since 2015, road traffic safety is included in the United Nations Agenda for Sustainable Development, meaning that methods for promoting road traffic safety are needed in order to reach the goals set for sustainable development. The purpose of this study is to examine the current situation and the potential of vehicle-related policy as a tool for promoting road traffic safety. LÄS MER

  7. 5. Circular economy in the construction industry: An insight into the difficulties and possibilities with improving the concrete recycling rate for housing in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Emelie Sundlin; [2021]
    Nyckelord :Sustainable Development; Circular Economy; Concrete Recycling; Recycled Aggregate; Housing; Construction Waste;

    Sammanfattning : In accordance with the Paris Agreement and the national goal of climate neutrality by 2045, Sweden needs to lower its greenhouse gas emissions. The second-largest source of CO2 emissions in the country comes from the production of cement, one of the main ingredients of concrete. LÄS MER
