  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 : 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

  4. 4. Faults and their influence on the dynamic behaviour of electric vehicles

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

    Författare :Daniel Wanner; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fault classification; vehicle dynamics; electric vehicle; failure; fault-tolerant control; reconfiguration; fault handling; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Sammanfattning : The increase of electronics in road vehicles comes along with a broad variety of possibilitiesin terms of safety, handling and comfort for the users. A rising complexityof the vehicle subsystems and components accompanies this development and has tobe managed by increased electronic control. LÄS MER
