1. 6. Controlling over-actuated road vehicles during failure conditions

   Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. LÄS MER

3. 7. 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.

4. 8. 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

5. 9. Vehicle-related injuries : with emphasis on fatality prevention

   Författare :Mats Öström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fatalities; injury; prevention; traffic; disease; alcohol; helmet; airbag;

   Sammanfattning : According to WHO, Sweden should aim to reduce unintentional fatalities, particularly vehicle-related injuries, by 25% by the year 2000. The aim of this thesis was to analyze vehicle-related injuries and injury events, especially the contributory effects of alcohol and disease and the injury reducing capacity of helmets and airbags in order to point out some preventive measures.

7. 10. Predicting Pedestrian Behavior in Urban Traffic Scenarios Using Deep Learning Methods

   Författare :Chi Zhang; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automated driving; pedestrian behavior; pedestrian trajectory prediction; deep learning; social interaction; pedestrian-vehicle interaction; urban traffic; urban traffic;

   Sammanfattning : Background: The statistics on global road safety show a great demand for reducing the fatalities caused by pedestrian-vehicle collisions. By utilizing artificial intelligence such as deep learning, human drivers can be supported by better driver assistance systems, and thereby the fatalities caused by human errors can be reduced.
