  1. 6. Evaluation of Train Driving with Lineside ATPand ERTMS Signaling

    Författare :Tomas Rosberg; Markus Bohlin; Birgitta Thorslund; Behzad Kordnejad; Ziemke Tom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transportsystem; Transport Systems;

    Sammanfattning : From many perspectives there is a need to understand more of how capacity, signal systems, anddriving behavior interact, and naturally since ERTMS is in its early stage, some areas are stillunexplored. The number of retrofitted ERTMS lines and new designed ERTMS lines are increasing inEurope, which implies extra focus on the capacity optimization in the network planning process. LÄS MER

  7. 10. Model Based Powertrain Control - Damping of Oscillations in a Heavy Duty Vehicle

    Författare :Maria Bruce; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Torsional resonances in the vehicle powertrain are undesired phenomena in automotive vehicles, since they cause longitudinal oscillations in the vehicle, which affect the driveability in a negative way and cause mechanical wear. It is the damping of these torsional resonances that has been the goal for this research work. LÄS MER
