  4. 2. Energy Efficient Longitudinal Control

    Author : Rickard Arvidsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous Vehicles; Optimal Control; Hybrid drivetrain control; Combustion Engines;

    Abstract : 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. READ MORE

  5. 3. Electric Machine Control for Energy Efficient Electric Drive Systems

    Author : Andreas Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modulation techniques; permanent magnet synchronous machine PMSM ; Energy efficiency; inverter control.; noise assessment;

    Abstract : Over the past decade, electric vehicles has increasingly become an area of attention for both academia and industry, much due to challenges such as emissions legislation and the environmental impact of the transportation sector. The absence of the broadband noise from the internal combustion engine brings new acoustic challenges for electric propulsion applications. READ MORE

  6. 4. Improving Fuel Efficiency of Commercial Vehicles through Optimal Control of Energy Buffers

    Author : Mohammad Khodabakhshian; Jan Wikander; Lei Feng; Johan Ölvander; KTH; []
