  1. 1. Driver model for a software in the loop simulation tool

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Yue Zheng; [2019]
    Nyckelord :HDV Heavy duty vehicle ; simulation tool; Driver model; longitudinal velocity controller; HDV tungt fordon ; simuleringsverktyg; förarmodell; longitudinell hastighetsregulator;

    Sammanfattning : For this project, a Software-In-the-Loop (SIL) simulation tool is used at Scania (“VTAB” – Virtual Truck and Bus), which simulates the submodels of the mechanical vehicle components together with the real control units. The simulation tool contains the following submodels: Engine model, Drivetrain model, Drive cycle model, Restbus model, and Driver model. LÄS MER

  3. 2. Convex Optimization-based Design of a Speed Planner for Autonomous Heavy Duty Vehicles

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Simon Frölander; Rawan Hasan; [2019]
    Nyckelord :;

    Sammanfattning : The objective of this master thesis is to design a speed planner for a heavy duty vehicle (HDV) that focuses on achieving a time efficient and comfortable driving, given different constraints such as road geometry, vehicle dynamics, acceleration, deceleration, speed limits etc. through an optimization based approach, namely by formulating it as a convex problem in a receding horizon fashion.

  4. 3. HDV Simulink Real World Model for Testing : A Study on Model Simplicity

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Robin Lindström; [2016]
    Nyckelord :;

    Sammanfattning :   The purpose of this thesis was to investigate the area of model complexity and see what precautions could be made to avoid the generation of complex models. These findings included five principles stated by M. Pidd which were implemented in the development of a new Simulink real world model of a heavy duty vehicle. LÄS MER

  5. 4. Information filter based sensor fusion for estimation of vehicle velocity

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Michael Refors; [2016]
    Nyckelord :;

    Sammanfattning : In this thesis, the possibility to estimate the velocity of a Heavy-duty vehicle (HDV) based on the Global Positioning System (GPS), an Inertial Measurement Unit (IMU) and the propeller shaft tachometer is investigated. The thesis was performed at Scania CV AB. LÄS MER

  7. 5. Model Predictive Control for Heavy Duty Vehicle Platooning

    Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Josefin Kemppainen; [2012]
    Nyckelord :platooning; MPC; fuel consumption; Vehicle-to-Vehicle communication;

    Sammanfattning : The aim of platooning is to enable several vehicles to drive in a convoy while each vehicle is controlled autonomously in longitudinal direction. All vehicles in the platoon are equipped with WiFi and can therefore apply Vehicle-to-Vehicle (V2V) communication. As a result, a short intermediate distance between the vehicles can be maintained.
