  1. 1. Research and Analysis of Suspension Dynamics of an Autonomous Bidirectional Road Vehicle

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Isabelle Gürsac; Tsimafei Klimantovich; [2023]
    Nyckelord :Bidirectional vehicle; 4WS; 4WD; suspension angles; kingpin inclination; camber angle; caster angle; toe angle; relative importance; suspension setup; suspension system; drivetrain; efficiency.; Dubbelriktat fordon; fyrhjulsstyrning; fyrhjulsdrift; hjulvinklar; Kingpin-lutningsvinkel; cambervinkel; castervinkel; toevinkel; relativ betydelse; fjädringsinställning; hjulupphängningssystem; drivlina; effektivitet.;

    Sammanfattning : The bidirectionality of road vehicles is a novel research area, which is directly connected with autonomy, efficiency, flexibility and sustainability of transportation. The research in this area is mostly performed with stringent restrictions in corporate secrecy. This fact makes the area publicly unexplored, moreover highly future oriented. LÄS MER

  3. 2. Control of an Over-Actuated Vehicle for Autonomous Driving and Energy Optimization : Development of a cascade controller to solve the control allocation problem in real-time on an autonomous driving vehicle

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Gianmarco Grandi; [2023]
    Nyckelord :LTV-MPC Linear Time-Varying Model Predictive Controller ; Trajectory following; Energy consumption; Vehicle stability; Vehicle model; Real-time performance; LTV-MPC Controllo a predizione del modello lineare tempo variabile ; Inseguimento di traiettoria; Consumo energetico; Stabilità del veicolo; Modello del veicolo; Prestazioni in tempo reale; LTV-MPC Linjär tidsvariabel modellförutsägande styrning ; spårföljning; energiförbrukning; fordonsstabilitet; fordonsmodell; prestanda i realtid;

    Sammanfattning : An Over-Actuated (OA) vehicle is a system that presents more control variables than degrees of freedom. Therefore, more than one configuration of the control input can drive the system to a desired state in the state space, and this redundancy can be exploited to fulfill other tasks or solve further problems.

  4. 3. Robotic Radar Target Test-system : Test vehicle

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ahmad Faroun; Sara Hallgran; [2022]
    Nyckelord :;

    Sammanfattning : Methods and tools for making testing and verification work more efficient and quality-assured are constantly being developed. These tests should ensure that the products delivered are set up correctly, have no defects and provide the desired functionality.In this project, a robot system and a computer program have been developed.

  5. 4. Design and Analysis of Electric Over-actuated Vehicle Suspension

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

    Författare :Ankith Suresh Athrey; [2020]
    Nyckelord :RCV; ITRL; MBD; CAD; FEM; RCV; ITRL; MBD; CAD; FEM;

    Sammanfattning : The main aim of this master thesis is to improve the performance of the Research Concept Vehicle (RCV). The RCV is an electric over-actuated vehicle developed at Integrated Transport Research Lab (ITRL) at KTH Royal Institute of Technology. The vehicle steer, camber, drive, and brake on each wheel of the vehicle. LÄS MER

  7. 5. Evaluations of Vibrations in a Wet Clutch

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik
