    Sammanfattning : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. LÄS MER

  4. 4. Improved road design for future maintenance analysis of road barrier repair costs

    Detta är en avhandling från Stockholm : KTH

    Författare :Hawzheen Karim; KTH.; Högskolan Dalarna.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Vägprojektering för minskade drift- och underhållskostnader; Keywords: highway maintenance; barrier repair cost;

    Sammanfattning : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. LÄS MER

  5. 5. Longitudinal Force Distribution and Road Vehicle Handling

    Detta är en avhandling från Stockholm : KTH

    Författare :Matthijs Klomp; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

    Sammanfattning : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.
