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

   Author : Sogol Kharrazi; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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.

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

6. 4. Performance Assessment of Long Combination Vehicles using Naturalistic Driving Data

   Author : Abhijeet Behera; Sogol Kharrazi; Erik Frisk; Mats Jonasson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The deployment of long combination vehicles (LCVs) is currently in progress in Sweden. LCV refers to heavy vehicles that are longer than 25.25 m, which is the conventional length limit in Swedish regulations. LCVs reduce operational costs, improve fuel efficiency and reduce CO2 emission per ton-km. READ MORE

7. 5. Tilting trains : Technology, benefits and motion sickness

   Author : Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

   Abstract : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. READ MORE
