    Abstract : The use of turbocharged Diesel engines is nowadays a widespread practice in the automotive sector: heavy-duty vehicles like trucks or buses, in particular, are often equipped with turbocharged engines. An accurate study of the flow field developing inside both the main components of a turbocharger, i.e. READ MORE

  3. 2. Model Predictive Control Using Neural Networks : a Study on Platooning without Intervehicular Communications

    University essay from Linköpings universitet/Reglerteknik

    Author : Gustav Ling; Klas Lindsten; [2017]
    Keywords : MPC; platooning; neural networks; velocity profile estimation; gear shift dynamics; heavy duty vehicle; machine learning;

    Abstract : As the greenhouse effect is an imminent concern, motivation for the development of energy efficient systems has grown fast. Today heavy-duty vehicles (HDVs) account for a growing part of the emissions from the vehicular transport sector. READ MORE

  4. 3. Improved Functionality for Driveability During Gear-Shift : A Predictive Model for Boost Pressure Drop

    University essay from Linköpings universitet/Fordonssystem

    Author : Mathias Brischetto; [2015]
    Keywords : boost pressure; predictive; simulation; model; gear shift; automatic transmission; automated manual transmission; engine control; mean value modelling; heavy duty truck;

    Abstract : Automated gear-shifts are critical procedures for the driveline as they are demanded to work as fast and accurate as possible. The torque control of a driveline is especially important for the driver’s feeling of driveability. READ MORE

  5. 4. Computationally Efficient Model for On-Board Simulation of Heavy Duty Diesel Engines

    University essay from Institutionen för systemteknik; Tekniska högskolan

    Author : Per Darnfors; Alfred Johansson; [2012]
    Keywords : Real-time engine model; on-board; driveline prediction; AMT; gear selection;

    Abstract : Simulating the translatory motion of a vehicle during a gear shift gives a good basis to evaluate performance and comfort of a gear shift. This evaluation can be used for gear shifting strategy in an automatic transmission. READ MORE

  6. 5. Modeling and Control of Opticruise - a Pneumatic Force Actuator

    University essay from KTH/Reglerteknik

    Author : Johan Schönning; Sebastian Zamani; [2007]
    Keywords : ;

    Abstract : Opticruise is an automated transmission system for manual gear boxes. The length stroke is a part of the Opticruise system, in which the mechanical gear shifting process is performed by pneumatic actuators. To reduce piston velocity before the cylinder walls are reached, an oil damper is attached to the pneumatic actuator. READ MORE
