2. 6. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

   Author : Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
   Keywords : 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;

   Abstract : 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%. READ MORE

4. 7. RANS Simulations of Interaction between Premixed Flame and Turbulence using OpenFOAM Library

   Author : Ehsan Yasari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; Turbulent flow; FSC model; Premixed turbulent combustion; OpenFOAM; Simulation; Countergradient turbulent transport; TFC model;

   Abstract : Unsteady multi-dimensional numerical simulation of turbulent flames is a widely recognized tool for research and development of future internal combustion engines capable of satisfying stringent requirements for ultra-low emission and highly efficient energy conversion. To attain success, such simulations need, in particular, elaborated CFD software and predictive models of turbulent burning. READ MORE

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

   Author : Peter Nilsson; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 9. Passenger kinematics in evasive maneuvers

   Author : Emma Larsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; volunteer kinematics; Active Human Body Model; pre-crash; active muscles; occupant variability; evasive maneuvers;

   Abstract : In situations that might lead to a vehicle crash, drivers often perform an evasive maneuver, such as braking or steering, in an attempt to avoid a crash. If a crash was not avoided, the maneuver could influence the injury outcome by altering the occupant’s position. READ MORE

7. 10. Logistics of Earthmoving Operations : Simulation and Optimization

   Author : Jiali Fu; Haris Koutsopoulos; Andreas Tapani; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Earthworks are a fundamental part of heavy construction engineering and involve the moving and processing of the soil surface of earth. Normally, earthmoving operations are carried out during the early stages of heavy construction projects. READ MORE
