  1. 1. Fuel Optimal Powertrain Control for Heavy Trucks Utilizing Look Ahead

    Författare :Maria Ivarsson; Lars Nielsen; Jan Åslund; Jan Wikander; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The road topography in highways affects the powertrain control of a heavy truck substantially since the engine power is low in relation to the vehicle weight. In large road gradients constant speed is not possible to keep, which would have been beneficial otherwise, and in some uphills shifting gears becomes inevitable. LÄS MER

  2. 2. Asymptotic analysis of junctions in multi-structures

    Författare :Jan Åslund; Alexander B. Movchan; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : A multi-structure is a compound domain that consists of several substructures such as solid bodies, thin shells and slender rods. In this thesis we consider different mixed boundary value problems in multi-structures. In the formulations of these problems a small perturbation parameter c is introduced, e.g. LÄS MER

  3. 3. Optimisation of Off-Road Transport Missions

    Författare :Jörgen Albrektsson; Jan Åslund; Lars Eriksson; Nikolce Murgovski; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Mines, construction sites, road construction and quarries are examples of applications where construction equipment are used. In a production chain consisting of several construction machines working together, the work needs to be optimised and coordinated to achieve an environmental friendly, energy efficient and productive production.

  4. 4. Autonomous Avoidance Maneuvers for Vehicles using Optimization

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

    Sammanfattning : To allow future autonomous passenger vehicles to be used in the same driving situations and conditions as ordinary vehicles are used by human drivers today, the control systems must be able to perform automated emergency maneuvers. In such maneuvers, vehicle dynamics, tire–road interaction, and limits on what the vehicle is capable of performing are key factors to consider. LÄS MER

  5. 5. Computation of Autonomous Safety Maneuvers Using Segmentation and Optimization

    Författare :Pavel Anistratov; Lars Nielsen; Björn Olofsson; Jan Åslund; Jonas Fredriksson; Linköpings universitet; []

    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.
