    Sammanfattning : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). LÄS MER

  2. 2. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes

    Författare :Lars Johannesson; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Management; Powertrain Control; Predictive Control; Dynamic Programming; Vehicle Telematics; Hybrid Electric Vehicle; Hybrid Electric Powertrains;

    Sammanfattning : 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.

  3. 3. Energy Efficient Longitudinal Control

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Rickard Arvidsson; [2018]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Vehicle Dynamics Control for Rollover Prevention

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Brad Schofield; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollover Prevention; Control Allocation; Nonlinear Control; Convex Optimization; Vehicle Dynamics;

    Sammanfattning : Vehicle rollover accidents are a particularly dangerous form of road accident. Existing vehicle dynamics controllers primarily deal with yaw stability, and are of limited use for dealing with problems of roll instability. LÄS MER

  5. 5. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Valerio Turri; Karl H. Johansson; Petros Ioannou; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. LÄS MER
