  2. 16. Online and Offline Identification of Tyre Model Parameters

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

    Abstract : 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. READ MORE

  4. 17. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

    Author : Anton Albinsson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise

    Author : Carsten Hoever; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling resistance; rolling noise; tyres; vibrations; waveguide finite element; tyre road interac- tion; BEM; fuel efficiency; parameter study; road surface properties; numerical modelling;

    Abstract : The road transportation sector places a severe burden on the environment in the form of CO2 emissions and road traffic noise. Both of these environmental prob- lems can be related to car and truck tyres. READ MORE

  6. 19. A Vibro-Acoustic Study of Vehicle Suspension Systems : Experimental and Mathematical Component Approaches

    Author : Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Henry Rice; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Vehicle suspension; Disc brake; Wheel rim Roughness noise; Interior tyre-road noise Component mode synthesis; Undeformed coupling interface;

    Abstract : The objective of the present work is to study the vehicle suspension as a vibro-acoustic system of high complexity, consisting of many sub-systems with fundamentally different acoustical properties. In a parallel numerical and experimental modelling effort, important contributions to the understanding of its behaviour have been achieved. READ MORE

  7. 20. Modelling the vibrations on a rolling tyre and their relation to exterior and interior noise

    Author : Patrik Sabiniarz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For most modern cars at normal driving speeds, tyre/road interaction is a major source tothe exterior as well as interior vehicle noise. The interaction between a tyre and a roadsurface generates tyre structure vibrations, leading to sound radiation into the surroundingair, and to dynamic forces acting on the wheel hub. READ MORE
