21. Transient vibrations from dry clutch operation in heavy-duty truck powertrains : Modelling, simulation and validation
Abstract : For internal combustion engines used in heavy-duty vehicles, increased engine efficiency and consequently reduced CO2 emissions can be obtained if the engine speed can be kept within an optimal speed range. This requires swift and frequent gear shifts where the dry friction clutch is utilized. READ MORE

22. Fuel-Efficient Centralized Coordination of Truck Platooning
Abstract : The problem of how to coordinate a large fleet of trucks with given itinerary to enable fuel-efficient platooning is considered. Platooning is a promising technology that enables trucks to save significant amounts of fuel by driving close together and thus reducing air drag. READ MORE

23. On integrated modularization in heavy-duty truck architecting
Abstract : Road transports face increasing challenges with respect to safety, legislations on lower emissions and traffic congestion, as well as numerous business challenges related to paradigm shifts in technology, tightened delivery times and cost constraints. Combination of truck electrification and automation may be utilized to address some of these issues. READ MORE

25. Towards model-based development of heavy truck synchronizers
Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. READ MORE
