  1. 21. Energy consumption prediction and routing for electric commercial vehicles

    Författare :Rafael Basso; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bayesian Inference; Machine Learning; Energy Consumption; Green Logistics; Reinforcement Learning; Electric Vehicles; Vehicle Routing; Eco-Routing;

    Sammanfattning : With the recent growing interest for electric vehicles as one of the initiatives to help tackle pollution and climate change, several opportunities and challenges emerge. This kind of vehicle releases no tailpipe emissions, is quieter, more energy efficient in terms of tank-to-wheels and simpler, which can lead to less maintenance. LÄS MER

  3. 22. Energy Scheduling of Electric Vehicles for Electricity Market Participation

    Författare :Pavan Balram; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; day-ahead market; EV aggregator; Electric vehicles; demand response; regulating power market; retailer planning;

    Sammanfattning : Global policy targets to reduce greenhouse gas emissions has led to increased interest in electric vehicles (EV) and their integration into the electricity network. Batteries in EVs offer flexibility from the demand side that could potentially compete against generating resources for providing power system services. LÄS MER

  4. 23. On Statistical Methods for Safety Validation of Automated Vehicles

    Författare :Daniel Åsljung; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

    Sammanfattning : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. LÄS MER

  5. 24. Active Flow Control for Drag Reduction of Heavy Vehicles

    Författare :Mohammad El-Alti; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active and Passive Flow Control; Tilt-rotor wing; Large-eddySimulation; Heavy vehicles; optimization; Full-scale road test; Trucks; Bluff-body; Wake; Drag reduction; Aircrafts; Response surface methodology; Synthetic-jet Actuator;

    Sammanfattning : This thesis considers the aerodynamics of trucks. The work focuses on the aerodynamic drag caused by the wake. Bluff-body flows are dominated by large dissipative vortex-shedding wakes with a low mean pressure compared to the high pressure on their frontal area. LÄS MER

  7. 25. Designing for Appropriate Trust in Automated Vehicles

    Författare :Fredrick Ekman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; trust phases; driving behaviour; explanatory and prescriptive model; information gestalt.; trust; automated vehicles AVs ; trust information; mixed method research;

    Sammanfattning : Automated vehicles (AVs) have become a popular area of research due to, among others, claims of increased traffic safety and user comfort. However, before a user can reap the benefits, they must first trust the AV. LÄS MER
