  1. 1. Tire Modeling and Friction Estimation

    Författare :Jacob Svendenius; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Vehicle Dynamics; Wheel Speed; Brush Model; Combined Slip; Tire Models; Teknik; Friction Estimation;

    Sammanfattning : New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. LÄS MER

  3. 2. Tire Models for Use in Braking Applications

    Författare :Jacob Svendenius; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tire model; friction; brush model; combined slip; vehicle;

    Sammanfattning : The tire is a significant part for control of a vehicle. For a well-working brake system the contact properties between the tire and the ground is the limiting factor for a safe braking. To get optimal performance it is important that the system can utilize all friction resources. LÄS MER

  4. 3. Motion Perception and Tire Models for Winter Conditions in Driving Simulators

    Författare :Artem Kusachov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; winter conditions; tire model; motion perception; winter driving simulation;

    Sammanfattning : Many traffic accidents happen due to winter conditions, like slippery roads and limited visibility. The road administrators put a lot of effort into snow removal and deicing the roads. The vehicle manufacturers have been working with functionality to support drivers in winter conditions (studded tires, ABS, ESC, etc.) for decades. LÄS MER

  5. 4. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling

    Författare :Penka Dinkova; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration response; mobility measurements; truck tyre; heavy vehicle; tyre-road noise; tyre; driving point mobility; transfer mobility; tire; vibration prediction; model;

    Sammanfattning : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available. LÄS MER

  7. 5. Methods for Frequency Domain Estimation of Continuous-Time Models

    Författare :Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. LÄS MER
