1. 1. On synchronization of heavy truck transmissions

   Författare :Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

   Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER

3. 2. Optimal Speed and Powertrain Control of a Heavy-Duty Vehicle in Urban Driving

   Författare :Manne Held; Jonas Mårtensson; Jonas Fredriksson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; optimal control; heavy-duty vehicles; trucks; powertrain control; fuel; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : A major challenge in the transportation industry is how to reduce the emissions of greenhouse gases. One way of achieving this in vehicles is to drive more fuel-efficiently. LÄS MER

4. 3. Optimal Control of Electrified Powertrains

   Författare :Martin Sivertsson; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Diesel-Electric; Hybrid Electric Vehicles;

   Sammanfattning : Vehicle powertrain electrification, i.e. combining the internal combustion engine (ICE) with an electric motor (EM), is a potential way of meeting the increased demands for efficient and low emission transportation, at a price of increased powertrain complexity since more degrees of freedom (DoF) have been introduced.
