2. 1. Fuel-Efficient Truck Platooning using Speed Profile Optimization

   Author : Sina Torabi; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis is concerned with fuel-efficient driving strategies for heavy-dutyvehicles driving on highways with varying topography. A method for reducingthe fuel consumption of single trucks and platoons consisting of several trucksis described and evaluated both in simulation and in real trucks. READ MORE

4. 2. Numerical optimization of pacing strategies in locomotive endurance sports

   Author : David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

   Abstract : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. READ MORE

5. 3. Fuel-efficient driving strategies

   Author : Sina Torabi; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed profile optimization; fuel efficiency; neural networks.; energy efficiency; genetic algorithms; performance analysis; road grade estimation; mass estimation; vehicle platooning;

   Abstract : This thesis is concerned with fuel-efficient driving strategies for vehicles driving on roads with varying topography, as well as estimation of road grade and vehicle mass for vehicles utilizing such strategies. A framework referred to as speed profile optimization (SPO), is introduced for reducing the fuel or energy consumption of single vehicles (equipped with either combustion or electric engines) and platoons of several vehicles.

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

   Author : Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

7. 5. Simulation model of a ship’s energy performance and transportation costs

   Author : Fabian Tillig; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; speed optimization; energy efficiency; wind-assisted propulsion.; performance prediction; energy systems model; ship design;

   Abstract : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.
