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.

4. 2. On Lateral Stability of Heavy Vehicle Combinations - Linking Accident Analysis and Vehicle Dynamics

   Author : Sogol Kharrazi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident Analysis; Vehicle Dynamics; Performance Measures; Lateral Stability Control; Heavy Trucks; Lateral Instability;

   Abstract : One of the hazardous motions of heavy trucks is lateral instability which can be defined as deviation from driver intended path due to skidding of the vehicle. Lateral instability is associated with 9% of heavy trucks involved in traffic accidents, which represents a considerable figure when translated to real accidents. READ MORE

7. 5. 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
