  1. 1. Effects of Dynamic Modeling on the Path Planning of Simulated Autonomous Vehicles

    University essay from Linköpings universitet/Fordonssystem; Linköpings universitet/Tekniska fakulteten

    Author : Elin Kidell Löwstedt; [2022]
    Keywords : ;

    Abstract : The purpose of the thesis was to evaluate the robustness of the Hybrid A* algorithm in regards to the levels of dynamic vehicle modeling, vehicle parameters and driving velocity. The original scope of the thesis project was to alter vehicle and tire models but this was discovered to be out of the time limits of the thesis project. READ MORE

  3. 2. Reinforcement learning for train dispatching : A study on the possibility to use reinforcement learning to optimize train ordering and minimize train delays in disrupted situations, inside the r ail simulator OSRD

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Teodora Popescu; [2022]
    Keywords : ;

    Abstract : Train dispatching is a complex process, especially when the train traffic is disrupted, as the decisions taken by the dispatchers can have substantial consequences on the delays of the trains. The most frequent dispatching decisions consists in changing the order of trains at convergence points, where two tracks unite to become a single track. READ MORE

  4. 3. Optimal Control and Race Line Planning for an Autonomous Race Car

    University essay from Linköpings universitet/Fordonssystem

    Author : Jacob Olausson; Jacob Larsson; [2021]
    Keywords : ;

    Abstract : In autonomous racing, arguably the most impactful modules in terms of lap time minimization are planning and control. Linköping University's Formula Student team has recently begun an organizational evolution towards building electric and autonomous race cars and this thesis aims to provide a solid foundation for a planning and control solution that the organization can continue to build upon.

  5. 4. Evaluation of Active Rear Steering through Multi-Body Simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Matteo Rossi; Gabriele Bertoli; [2021]
    Keywords : Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control; Vehicle dynamics; Active rear steering; active systems; automotive; MBS; Simpack; Volvo; CAE; single-track model; bicycle model; feedforward control;

    Abstract : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

  6. 5. Improvement of an existing Integrated Vehicle Dynamics Control System influencing an urban electric car

    University essay from KTH/Flygdynamik

    Author : Arihant Sureka; [2020]
    Keywords : model predicitve control; MPCA; vehicle dynamics; Single track model; Rear wheel steering; kalametric; state estimation; design matrix; aliasing; kalman filter; projectionalgorithm; resolution; model predicitve control; MPCA; kalametric; tillståndsestimering; designmatris; vikningsdistorsion; kalmanfilter; projection algorithm; upplösning;

    Abstract : The Integrated Vehicle Dynamics Control (IVDC) concept can influence the vehicle behaviour both longitudinally and laterally with just one upper level control concept and further lower level controllers. This demands for state estimation of the vehicle which also includes estimating parameters of interest for the vehicle dynamicist. READ MORE
