  1. 1. Dynamic axel load estimation for an electrified vehicle : Normalkraftestimering på drivaxeln

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Majd Barakat; [2023]
    Nyckelord :Vehicle dynamics; Suspension systems; Vehicle design; Bounce-Pitch model; Car quarter model; Normal force; Normal force estimation;

    Sammanfattning : The brake system is critical for ensuring safe driving and has been the focus of development for many years. Pneumatic braking technology is commonly used in heavy vehicles,but it results in energy wastage and high service costs. Some countries mandate auxiliarybraking systems to assist in stopping the vehicle in addition to service brakes. LÄS MER

  3. 2. Dynamic Braking: A new Approach for Testing Electrical Machines.

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Eloy Pedro Sánchez Caton; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. LÄS MER

  4. 3. Hybrid Electric & Hydraulic Drivers

    Master-uppsats, Fluida och mekatroniska system

    Författare :Mohammadreza Sadeghi; Ali Mohammed Fahimi Rezaii; [2010]
    Nyckelord :;

    Sammanfattning : The environmental impact of fossil fuel consumption has been a significant issue over the last decade. Mainly because of public awareness, increased fuel cost and stricter legislation. Today’s technological improvements have reduced fuel consumption and also emission of vehicles considerably. LÄS MER

  5. 4. Pressure Control of a Pneumatic Actuator Using On/O Solenoid Valves

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Maisam Jeddi Tehrani; [2008]
    Nyckelord :;

    Sammanfattning : Nowadays a very important aspect in heavy duty vehicles is the braking system. The braking system can be divided into EBS brakes, exhaust brake and retarder, where the latter is of interest in the present Master's Thesis. This thesis presents an investigation whether it is possible to substitute today's concept, i.e. LÄS MER

  7. 5. Modeling and Control of Retarder using On/Off Solenoid Valves

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Vidar Steinsland; [2008]
    Nyckelord :;

    Sammanfattning : The Retarder is one of the main components in Scania's trucks' braking system and is used to brake down the truck and for maintaining a steady speed on descents. This Master's Thesis aims to investigate if the current system which uses a proportional valve to control the air pressure in the Retarder, can be replaced with two on/o® solenoid valves and a pressure chamber to control the air pressure, which would result in a cheaper and more robust system.
