    Abstract : 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. READ MORE

  2. 2. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    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

  3. 3. On Energy Management Strategies for Hybrid Electric Vehicles

    Author : Lars Johannesson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

    Abstract : 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. READ MORE

  4. 4. On Control of Permanent-Magnet Synchronous Motors in Hybrid-Electric Vehicle Applications

    Author : Oskar Wallmark; Chalmers University of Technology; []
    Keywords : phase-locked loop; signal injection; Electric drive; sensorless control; harmonics; position estimation; speed estimation; hybrid-electric vehicle; permanent-magnet synchronous motor; electric vehicle; vector control;

    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

  5. 5. Radical Innovation: Management and policy for electric and hybrid electric vehicle development

    Author : Hans M Pohl; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; first-mover; hybrid; policy; electric vehicle; interparadigmatic; innovation; evolutionary; radical; Paradigm; automotive;

    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
