  1. 16. Fuel Consumption Tuning for Electric All Wheel Drive System

    Uppsats för yrkesexamina på avancerad nivå, Signaler och System

    Författare :Richard Hallvig; [2013]
    Nyckelord :Bränsleekonomi; hybridbilar;

    Sammanfattning : This report investigates methods to reduce fuel consumption in SAAB's prototype hybrid car. It is primarily concerned with changes in the final drive ratio (FDR) of the gearbox. Reducing the FDR lowers the engine speed, allowing the engine to run at a more efficient operating point. LÄS MER

  3. 17. Accuracy of PSA's DPF soot load estimator calibrated by means of a DoE model

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :THOMAS LE BIHAN; [2013]
    Nyckelord :;

    Sammanfattning : The combustion process happening in the Diesel engine is naturally producing soot. These soot emissions have been known for being harmful for both our environment and especially our health. Aware of this situation, the governments worldwide have defined emission limits for our vehicles. LÄS MER

  4. 18. Wastegate Actuator Modeling and Tuning of a PID Controller for Boost Pressure Control

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Andreas Thomasson; [2009]
    Nyckelord :PID; Wastegate; Boost Control; Turbo Charging;

    Sammanfattning : In some turbochargers, boost pressure is reduced by opening the wastegate valve. In a modern turbo charged car, the most common way for opening the wastegate is with a pneumatic actuator and an air control solenoid, controlled by the ECU. LÄS MER

  5. 19. Road Roughness Etimation Using Available Vehicle Sensors

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Johan Lundström; [2009]
    Nyckelord :Heavy truck; Road Roughness;

    Sammanfattning : Road conditions affect fuel efficiency and vehicle fatigue when driving heavy trucks. Information about traveled road conditions enable optimization of chassis configuration when driving, and logging of vehicle stress. Previous work on this topic focus mainly on tuning of active suspension parameters in the car industry. LÄS MER

  7. 20. Computing The Ideal Racing Line Using Optimal Control

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Thomas Gustafsson; [2008]
    Nyckelord :Optimal control; Racing; Car tuning;

    Sammanfattning : In racing, it is useful to analyze vehicle performance and driving strategies to achieve the best result possible in competitions. This is often done by simulations and test driving. In this thesis optimal control is used to examine how a racing car should be driven to minimize the lap time. LÄS MER
