  1. 1. Adaptive Rolling Radius Estimation

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Rickard Wretlind; William Wärn; [2023]
    Nyckelord :Rolling Radius; Estimation; Rolling Radius Estimation; Tire; Tires;

    Sammanfattning : Tire tread health is essential for safe operation of a passenger vehicle. Worn out tires significantly increases the risk of traffic accidents and hydroplaning. This thesis investigates the possibility to detect tire tread wear by estimating the effective rolling radius of a tire. LÄS MER

  3. 2. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Joachim Neguembor; [2022]
    Nyckelord :Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

    Sammanfattning : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. LÄS MER

  4. 3. Evaluation of Active Rear Steering through Multi-Body Simulation

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Matteo Rossi; Gabriele Bertoli; [2021]
    Nyckelord :Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Sammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

  5. 4. Steering Control During μ-split Braking for an Autonomous Heavy Road Vehicle

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Sebastian Haglund; Henrik Johansson; [2020]
    Nyckelord :steering; braking; autonomous; μ-split; split-μ; truck; vehicle; control;

    Sammanfattning : A critical maneuver for a heavy vehicle is braking with different friction on the left and right hand side of the vehicle, called μ-split. This results in an unwanted yaw torque acting on the vehicle. During this situation, the driver maintains the lateral stability and follows the desired path by corrective steering. LÄS MER

  7. 5. The Effects of Sensor Fusion on Localisation in a Sparse, Outdoor Environment

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Kayla Kearns; [2020]
    Nyckelord :;

    Sammanfattning : This thesis compares the results of a localisation algorithm for a mobile robot in both a sparse and a densely featured environment whilst varying key parameters. The software and hardware required to enable the mobile robot to localise itself in the sparsely featured, GPS-denied, outdoor environment is described. LÄS MER
