1. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles
Sammanfattning : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. LÄS MER
2. Electric vehicles in action
Sammanfattning : This thesis analyses the political and practical conditions for introducing electric vehicles in Swedish public authorites and discusses the potential for using electric vehicles in public transport and public fleets. The work has been carried out using an interdisciplinary research approach. LÄS MER
3. On Discharge Strategies for Plug-in Hybrid Electric Vehicles
Sammanfattning : During recent years electrification of vehicles has emerged as a promisingtechnology to reduce oil dependency and CO2 emissions within the transportationsector. At the present day several automotive manufacturers areabout to introduce plug-in hybrid electric vehicles to the market, i.e. LÄS MER
4. On Energy Management Strategies for Hybrid Electric Vehicles
Sammanfattning : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. LÄS MER
5. Gear engagement control for transmissions in hybrid electric vehicles
Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER
