  1. 16. Mechanisms and Phenomena in Braking and Gripping

    Författare :Lars Hammerström; Staffan Jacobson; XXX XXX; Uppsala universitet; []
    Nyckelord :Materials science; Friction; Brake; Texture; Squeal; Materialvetenskap;

    Sammanfattning : Applications relying on a high static friction include various types of fixtures, couplings, bolted joints, torsion joints, etc. The common characteristic of these applications is that they rely on the friction force to maintain the relative position of two mating surfaces.

  3. 17. Towards Crash-Free Driving: Opportunities and Limitations of Automated Emergency Braking in Intersections

    Författare :Ulrich Sander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AEB; left turn across path; V2X communication; Intersection; accident avoidance; straight crossing path; automated emergency braking; market penetration; injury mitigation; junction;

    Sammanfattning : Intersections are a global traffic safety concern. In the Unites States, about half of the fatal road traffic accidents take place at intersections or were related to them. In the European Union, about one fifth of the road traffic fatalities occur at intersections. LÄS MER

  4. 18. 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

  5. 19. Health Losses in Motorcycle Crashes - Injury Analysis of Crashes into Road Barriers and Evaluation of Antilock Braking Systems

    Författare :Matteo Rizzi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antilock Braking Systems; Powered Two Wheelers; Safety; Injury; Stability; Road Barrier; Health Loss; Crash; Motorcycle;

    Sammanfattning : Motorcycles crashes are a growing road safety problem. While the traditional safety approach has focused on protective gear and rider education, with the Vision Zero approach, the designers of the road transport system are considered responsible for its design and operation.

  7. 20. Modelling E-scooterist Braking and Steering for Collision Avoidance

    Författare :Tianyou Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bicycles; Cycling safety; Active safety; Bicycle kinematics; E-scooters; Micromobility;

    Sammanfattning : Introduction: In the last few years, new road safety issues have emerged with the growing popularity of novel micromobility vehicles (MMVs). The term ‘novel MMV’ includes, in addition to electrically assisted bicycles, electric kick scooters (e-scooters) and Segway balance scooters (Segways)—which are usually distinct in appearance and operation from traditional MMVs (conventional bicycles).
