  1. 1. 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

  3. 2. Steering Based Lateral Performance Control of Long Heavy Vehicle Combinations

    Författare :Sogol Kharrazi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trailer Swing; Active Steering; Offtracking; Heavy Vehicle; Lateral Performance; Sine with Dwell; Accident Analysis; Longer Combination Vehicle; Rearward Amplification;

    Sammanfattning : In this thesis the lateral performance of heavy vehicle combinations, specifically longer combination vehicles, is discussed. The use of longer combination vehicles is promoted by their positive impact on the traffic congestion problem, as well as their economic and environmental benefits due to reduced fuel consumption and emissions.

    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

  5. 4. Traffic Situation Management for Driving Automation of Articulated Heavy Road Transports - From driver behaviour towards highway autopilot

    Författare :Peter Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; driving simulator; driving principles; driving automation; vehicle model; articulated heavy-vehicles; vehicle dynamics; long combination vehicles;

    Sammanfattning : In this thesis traffic situation management for driving automation of long combination vehicles is discussed. The automation targets high-speed driving in multiple-lane, one-way roads. Traffic situation predictions, traffic situation manoeuvres and driving principles are studied specifically. LÄS MER

  7. 5. Aerodynamics of vehicle platooning

    Författare :Johannes Törnell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; close proximity; drag; platooning; cab over engine; aerodynamics; yaw; wake; side wind; truck; inter-vehicle distance; lateral offset;

    Sammanfattning : Many factors are pushing automotive manufacturers to increase the efficiency of their fleets; some of these are legislative (requiring reduced greenhouse gas emissions) as well as ensuring sufficient range and power consumption in electric vehicles. An important part of improving the energy efficiency of road vehicles is reducing their aerodynamic drag. LÄS MER
