  1. 1. Truck Steering System and Driver Interaction

    Författare :Kristoffer K D Tagesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steering system; active safety; driver behaviour; active steering; torque feedback; heavy trucks;

    Sammanfattning : This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented.

  3. 2. Steering control for haptic feedback and active safety functions

    Författare :Tushar Chugh; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; position control; coupled stability; passivity; steering system; uncoupled stability; transparency; active safety; haptic feedback; torque control; state estimation;

    Sammanfattning : Steering feedback is an important element that defines driver–vehicle interaction. It strongly affects driving performance and is primarily dependent on the steering actuator's control strategy. LÄS MER

  4. 3. On Active Suspension in Rail Vehicles

    Författare :Alireza Qazizadeh; Sebastian Stichel; Rickard Persson; T. X. Mei; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active suspension; ride comfort; wear; skyhook control; H_infinity control; two-axle rail vehicle; safety; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : The topic of this PhD thesis is active suspension in rail vehicles whichis usually realized through sensors, controllers and actuation components.A well established example of an active suspension is the tiltingcontrol system used to tilt the carbody in curves to reduce centrifugalacceleration felt by passengers.

  5. 4. On Performance Evaluation of Automotive Active Safety Systems

    Författare :Jonas Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Semi-Autonomous Vehicles; Active Safety; Automotive; Augmented Reality.; Verification; Performance Evaluation; Decision Making;

    Sammanfattning : Road traffic accidents are a major global problem, annually causing over 1.2 million fatalities. To improve road safety, active safety systems support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents.

  7. 5. Models for tracking in automotive safety systems

    Författare :Fredrik Bengtsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion models; active safety; vehicle tracking; Automotive; radar detections; preventive safety;

    Sammanfattning : This thesis treats the three main components of a tracking system: motion models, sensor models and implementation architecture. A tracking system utilizes models to extract as much information as possible from a set of sensors, with the purpose of estimating the state of a dynamic system. LÄS MER
