  1. 21. Energy consumption of an off-road modified pick-up and the possibility of hybridisation or electrification

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Hédinn Hauksson; [2018]
    Nyckelord :;

    Sammanfattning : Arctic Trucks have been modifying vehicles such as the Toyota Hilux, Toyota Land Cruiser, Isuzu D-Max, Nissan Patrol and Nissan Navara for over 25 years for special projects as well as for recreational purposes both in Iceland and other countries. Arctic Trucks started up as a sub-division for Toyota Iceland but became an independent company in 2005. LÄS MER

  3. 22. Trajectory Planning for Off-road Autonomous Driving

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ji Yin; [2018]
    Nyckelord :;

    Sammanfattning : The thesis develops a trajectory planner which operates in a formula racing scenario. The proposed trajectory planner gives time-optimal off-road trajectory planning solutions and generates sequences of control signals for the vehicle to follow the trajectory. LÄS MER

  4. 23. Terrain Classification to find Drivable Surfaces using Deep Neural Networks : Semantic segmentation for unstructured roads combined with the use of Gabor filters to determine drivable regions trained on a small dataset

    Master-uppsats, KTH/Robotik, perception och lärande, RPL

    Författare :Agneev Guin; [2018]
    Nyckelord :Semantic segmentation; Deep learning; Gabor filters; Drivable surfaces;

    Sammanfattning : Autonomous vehicles face various challenges under difficult terrain conditions such as marginally rural or back-country roads, due to the lack of lane information, road signs or traffic signals. In this thesis, we investigate a novel approach of using Deep Neural Networks (DNNs) to classify off-road surfaces into the types of terrains with the aim of supporting autonomous navigation in unstructured environments.

  5. 24. Electrification of a diesel-hydraulic off-road machine

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Dhruv Phadke; [2017]
    Nyckelord :driveline control; efficiency; energy storage; XT28; drivlina; energilagring; reglering; XT28; verkningsgrad;

    Sammanfattning : This report is for the Master of Science thesis project undertaken for KTH Royal Institute of Technology in collaboration with the Forestry Research Institute of Sweden (Skogforsk) for the Forestry Master Thesis School. The aim of this project was to theoretically explore the possibility of replacing the hydraulic driveline with an electric series driveline and to understand the differences between using one or the other so that it can be convincingly concluded if a Diesel-electric driveline in Forestry forwarders is a worthwhile endeavour or not.

  7. 25. Soil watermap usage in planning of thinnings

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Aigars Loks; [2017]
    Nyckelord :soil water maps; Norway spruce; thinnings; strip road; DTW;

    Sammanfattning : Off-road driving with heavy machinery (harvesters and forwarders) in logging operations nowadays is essential. It is the main reason why efficiency of harvesting has increased so significantly. Unfortunately it also has its downsides – one of which is increased soil damage in strip roads. LÄS MER
