31. Energy Efficient Longitudinal Control
Sammanfattning : Vehicles are contributing to global and local environmental problems as a result of fossil fuels. A majority of the combustion engine population is driven by fossil fuels and electrified vehicles are also to a large extent dependent on electricity production from fossil fuels. LÄS MER
32. Vehicle Level Diagnosis for Hybrid Powertrains
Sammanfattning : There are possibilities to reduce the fuel consumption in trucks using hybrid technology. New components are added when hybridizing a vehicle, and these need to be monitored due to safety and legislative demands. Diagnosis aspects due to hybridization of the powertrain are investigated using a model of a long haulage truck. LÄS MER
33. On Numerical Descriptions of Road Transport Missions
Sammanfattning : This thesis addresses some issues of current interest in energy consumption prediction through simulation. First, we review the situation for rating, regulation and legislation of CO$_2$-emissions for cars and heavy vehicles. LÄS MER
34. Advanced Fluid-Structure Interaction Modelling and Simulation for Aerospace Applications
Sammanfattning : Numerical fluid-structure interaction (FSI) methods for the prediction of aeroelastic phenomena are important within aerospace. The continuous development of computer technologies has enabled the use of more advanced FSI methods. The use of advanced methods has the potential to provide more accurate predictions. LÄS MER
35. Control of Hybrid Electric Vehicles with Diesel Engines
Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER
