  1. 1. On Drive Force Distribution and Road Vehicle Handling - A Study of Understeer and Lateral Grip

    Författare :Matthijs Klomp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drive force distribution; drive force; vehicle handling; lateral grip; understeer; acceleration; steady-state cornering; vehicle dynamics; combined slip;

    Sammanfattning : Computer controlled vehicle sub-systems aimed to support drivers in various drivingsituations are rapidly increasing in number and sophistication. These systemshave evolved from anti-lock braking and traction control systems, to electronic stabilitycontrol. LÄS MER

  3. 2. Difficulties to Read and Write Under Lateral Vibration Exposure : Contextual Studies Of Train Passengers Ride Comfort

    Författare :Jerker Sundström; Shafiquzzaman Khan; Neil J. Mansfield; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lateral vibrations; passenger activities; reading; writing; sitting posture; frequency weighting; rated difficulty; field study; laboratory study; transient vibrations; stationary vibrations.; Vehicle engineering; Farkostteknik;

    Sammanfattning : Many people use the train both as a daily means of transport as well as a working place to carry out activities such as reading or writing. There are, however, several important factors in this environment that will hamper good performance of such activities. LÄS MER

  4. 3. Physical Modeling of Brain and Head Kinematics

    Författare :Johan Ivarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

  5. 4. Adaptive Lateral Model Predictive Control for Autonomous Driving of Heavy-Duty Vehicles

    Författare :Goncalo Collares Pereira; Jonas Mårtensson; Bo Wahlberg; Henrik Pettersson; Daniel Axehill; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Control Stability; Experimental Evaluation; Fleet Evaluation; Adaptive Control; Automatic Control; Autonomous Vehicles; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Autonomous Vehicle (AV) technology promises safer, greener, and more efficient means of transportation for everyone. AVs are expected to have their first big impact in closed environments, such as mining areas, ports, and construction sites, where Heavy-Duty Vehicles (HDVs) operate. LÄS MER

  7. 5. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

    Författare :Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

    Sammanfattning : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. LÄS MER
