  1. 11. Computation of Autonomous Safety Maneuvers Using Segmentation and Optimization

    Författare :Pavel Anistratov; Lars Nielsen; Björn Olofsson; Jan Åslund; Jonas Fredriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis studies motion planning for future autonomous vehicles with main focus on passenger cars. By having automatic steering and braking together with information about the environment, such as other participants in the traffic or obstacles, it would be possible to perform autonomous maneuvers while taking limitations of the vehicle and road–tire interaction into account.

  3. 12. Towards Energy Efficient Control of Individual Wheel Drive Articulated Vehicles

    Författare :Fredrik Broström; Jonas Fredriksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : The aim of this thesis was to increase knowledge in the area of articulated vehicles and specifically energy efficient traction control. Eletrical propulsion of vehicles has started to be popular due to its versatility and freedom of design. LÄS MER

  4. 13. Exploring force allocation control of over actuated vehicles

    Författare :Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Lars Drugge; Jonas Fredriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the concern for environmental changes and diminishing oil resources grows more and more, the trend of new vehicle concepts now includes full electric or partly electric propulsion systems. The introduction of electric power sources enables more advanced motion control systems due to electrification of the vehicle's actuators, such as individual wheel steering and in wheel hub motors.

  5. 14. Evaluation, Transformation, and Extraction of Driving Cycles and Vehicle Operations

    Författare :Peter Nyberg; Lars Nielsen; Erik Frisk; Jonas Fredriksson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : A driving cycle is a representation of how vehicles are driven and  is usually represented by a set of data points of vehicle speed  versus time.  Driving cycles have been used to evaluate vehicles for  a long time. LÄS MER

  7. 15. Interaction and Uncertainty-Aware Motion Planning for Autonomous Vehicles Using Model Predictive Control

    Författare :Jian Zhou; Erik Frisk; Björn Olofsson; Jonas Fredriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Motion planning plays a significant role in enabling advances of autonomous vehicles in saving lives and improving traffic efficiency. In a predictive motion-planning strategy, the ego vehicle predicts the motion of surrounding vehicles and uses these predictions to plan collision-free reference trajectories. LÄS MER
