1. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles
Abstract : 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. READ MORE

2. Radical Innovation: Management and policy for electric and hybrid electric vehicle development
Abstract : Technological change can be divided into two categories: in line with the mainstream trajectory or paradigm (continuous, incremental), or breaking with it (discontinuous, radical). This thesis aims to increase understanding of the latter type: paradigmatic shifts in technology. READ MORE

3. On Control of Permanent-Magnet Synchronous Motors in Hybrid-Electric Vehicle Applications
Abstract : This thesis deals with design and analysis of the control system structure for electric drives equipped with permanent-magnet synchronous motors with a salient rotor. The intended application is propulsion in electric- and hybrid-electric vehicles. READ MORE

4. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction
Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE

5. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes
Abstract : At the highest level in the powertrain control system in a hybrid electric vehicle an energy management controller interprets the driver’s pedal actions as a torque that is to be delivered at the powertrain output. The energy management controller distributes this torque between the engine and the electric machines and decides when to change gear and when to turn off the engine for pure electric propulsion.
