    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    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.

    Sammanfattning : Popular Abstract in Swedish Dagens samhälle är väldigt beroende av fordon av olika slag. Aldrig förr har människor rest till olika delar av världen, så mycket som idag. Den enorma mängden resors och transporter som sker varje dag är en tung belastning för vår natur. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    Författare :Lars Johannesson; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

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

    Detta är en avhandling från Stockholm : KTH
