1. 1. Driver-Vehicle Interaction : Identification, Characterization and Modelling of Path Tracking Skill

   Författare :Andreas Erséus; Stensson Trigell Annika; David Cole; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Vehicle engineering; Farkostteknik; Psychology; Psykologi;

   Sammanfattning : Since the dawn of the automobile, driver behaviour has been an issue. Driving can result in accidents that may harm not only the driver but also passengers and the surroundings. This calls for measures that restrict the usage of vehicles and to assist the individual driver to conduct the driving in a safe, yet practically efficient manner. LÄS MER

3. 2. Predictive model of perceived driving stability at high speeds under aerodynamic excitations

   Författare :Arun Kumar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver-vehicle interaction; unsteady aerodynamics; Driving simulator; on-road tests; predictive model; vehicle stability; subjective evaluation;

   Sammanfattning : The automotive industry is continuously advancing towards more energy-efficient vehicle designs.  Streamlined vehicles have low aerodynamic drag but have the potential to be unstable when  exposed to external excitations such as unsteady aerodynamic forces created by the flow of air  around them.

4. 3. The Contribution of Vehicle, Occupant and Other Factors to the Risk of Injury as a Result of Vehicle Rollover

   Författare :Stephen Ridella; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intrusion; Kinematics; Injury Causation; Roof Inversions.; Rollover; CIREN; NASS-CDS; Restraints;

   Sammanfattning : Injuries and deaths as a result of vehicle rollover have been declining in recent years like other crash modes, but it still remains a consistently large contributor of the overall crash fatalities in the United States. Also, more new vehicles are becoming equipped with electronic stability control and are subject to new regulations that call for increased roof strength and countermeasures to prevent ejection during rollover crashes.

5. 4. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

   Författare :Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. LÄS MER

7. 5. Heterogeneity in Car Occupant Safety

   Författare :Alexandros Leledakis; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-world safety; Human Body Model; Occupant posture; Crash Configurations; Anthropometric variation; Finite element; Sensitivity analysis; Individualised Restraint Systems; Vehicle safety assessment; Seat adjustment;

   Sammanfattning : This thesis ultimately aims to enhance occupant protection by incorporating aspects of real-world crash heterogeneity, often overlooked within current safety assessments. By investigating the effects of crash heterogeneity and broadening the comprehensiveness of occupant safety assessments, it seeks to support the development of more effective future vehicle safety systems.
