  1. 6. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

    Författare :Anton Albinsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

    Sammanfattning : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. LÄS MER

  4. 8. Online and Offline Identification of Tyre Model Parameters

    Författare :Anton Albinsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state estimation; computer aided engineering; tyre testing; parameter estimation; tyre-road friction estimation; active safety; simulation; vehicle dynamics;

    Sammanfattning : The accelerating development of active safety system and autonomous vehicles put higher requirements on both environmental sensing and vehicle state estimation as well as virtual verification of these systems. The tyres are relevant in this context due to the considerable influence of the tyres on the vehicle motion and the performance boundaries set by the tyres. LÄS MER

  5. 9. Friction in metal powder pressing : measurement and characterisation

    Författare :Naghi Solimanjad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : The present work describes different methods for measuring and characterisation of friction in powder compaction process. A new test apparatus has been developed and presented which gives possibility of directly measurement of coefficient of friction during pressing from low to relative high density. LÄS MER
