1. Fuel-Efficient Truck Platooning using Speed Profile Optimization
Sammanfattning : 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. LÄS MER
2. Numerical optimization of pacing strategies in locomotive endurance sports
Sammanfattning : 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. LÄS MER
3. Fuel-efficient driving strategies
Sammanfattning : 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.

4. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning
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
5. Simulation model of a ship’s energy performance and transportation costs
Sammanfattning : 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.
