    Sammanfattning : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. LÄS MER

  3. 2. Transportation Mission Based Optimization of Heavy Vehicle Fleets including Propulsion Tailoring

    Författare :Toheed Ghandriz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimization; heterogeneous heavy vehicle fleet; optimal energy management; propulsion system tailoring; Automated Driving Systems; electrified propulsion; total cost of ownership; electromobility; transportation mission; fleet sizing;

    Sammanfattning : Over decades freight vehicles were produced for a wide range of operational domains so that vehicle-manufacturers were not concerned much about the actual use-cases of the vehicles. Environmental issues, costumer expectations along with growing demand on freight transport created a competitive environment in providing better transportation solutions. LÄS MER

  4. 3. Subjective perception and prediction model of vehicle stability under aerodynamic excitations

    Författare :Arun Kumar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human-vehicle interaction; prediction model; drivability; unsteady aerodynamics; Driving simulator; driver perception.; vehicle stability;

    Sammanfattning : The current automotive era is moving towards electrified vehicle propulsion. As a result, an energy efficient vehicle design becomes one of the top priorities. From an aerodynamics point of view, the vehicle should be more streamlined for minimal aerodynamic drag. LÄS MER

  5. 4. On Traffic Situation Predictions for Automated Driving of Long Vehicle Combinations

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; braking; steering; heavy trucks; automated driving; long vehicle combination; active safety; vehicle dynamics; prediction; driver behaviour;

    Sammanfattning : The introduction of longer vehicle combinations for road transports than are currently allowed is an important viable option for achieving the environmental goals on transported goods in Sweden and Europe by the year 2030. This thesis addresses how driver assistance functionality for high-speed manoeuvring can be designed and realized for prospective long vehicle combinations. LÄS MER

  7. 5. On the Performance of Long-Range Autonomous Underwater Vehicles : Enhancing the Endurance of AUVs

    Författare :Clemens Deutsch; Jakob Kuttenkeuler; Roger Berg; Martin Ludvigsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous underwater vehicles; Underwater gliders; Propulsion; Fuel cell; Energy management strategies; Autonom undervattensfarkost; Undervattensglidning; Propulsion; Bränslecell; Energy Management Strategies; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Autonomous underwater vehicles (AUVs) are robotic platforms that are commonly used to gather environmental data, provide bathymetric images, and perform manipulation tasks. These robots are used not only for scientific, but also for industrial and military purposes. LÄS MER
