1. Analysis and control of a hybrid vehicle powered by free-piston energy converter
Sammanfattning : The introduction of hybrid powertrains has made it possible to utilise unconventional engines as primary power units in vehicles. The free-piston energy converter (FPEC) is such an engine. It is a combination of a free-piston combustion engine and a linear electrical machine. LÄS MER
2. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER
3. On evaluation and optimization of hybrid electric vehicle powertrain systems
Sammanfattning : .... LÄS MER
4. Evaluation, Generation, and Transformation of Driving Cycles
Sammanfattning : Driving cycles are important components for evaluation and design of vehicles. They determine the focus of vehicle manufacturers, and indirectly they affect the environmental impact of vehicles since the vehicle control system is usually tuned to one or several driving cycles.
