1. 1. Adaptive Lateral Model Predictive Control for Autonomous Driving of Heavy-Duty Vehicles

   Författare :Goncalo Collares Pereira; Jonas Mårtensson; Bo Wahlberg; Henrik Pettersson; Daniel Axehill; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Control Stability; Experimental Evaluation; Fleet Evaluation; Adaptive Control; Automatic Control; Autonomous Vehicles; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Autonomous Vehicle (AV) technology promises safer, greener, and more efficient means of transportation for everyone. AVs are expected to have their first big impact in closed environments, such as mining areas, ports, and construction sites, where Heavy-Duty Vehicles (HDVs) operate. LÄS MER

3. 2. Predictive control for autonomous driving : With experimental evaluation on a heavy-duty construction truck

   Författare :Pedro Lima; Bo Wahlberg; Jonas Mårtensson; Alberto Bemporad; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; automatic control; heavy-duty vehicles; mining; trucks; clothoids; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Autonomous vehicles is a rapidly expanding field, and promise to play an important role in society. In more isolated environments, vehicle automation can bring significant efficiency and production benefits and it eliminates repetitive jobs that can lead to inattention and accidents. LÄS MER

4. 3. Lateral epicondylitis : intramuscular blood flow, pressure and metabolism in the ECRB muscle

   Författare :Eva Oskarsson; Karin Piehl Aulin; Eva Nylander; Örebro universitet; []
   Nyckelord :Lateral epicondylitis; ECRB; intramuscular microcirculation; intramuscular pressure; botulinum toxin; muscle metabolism; pain; MEDICINE; MEDICIN; Idrottsvetenskap; Sports Science;

   Sammanfattning : Lateral epicondylitis is classified as an overuse injury and the main symptom is pain from the lateral side of the elbow. There is general agreement that the extensor carpi radialis brevis (ECRB) muscle and its proximal tendon play a central role in the development of lateral epicondylitis. However, the pathophysiology is to a large extent unclear. LÄS MER

5. 4. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

   Författare :Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. LÄS MER

7. 5. On Robust Steering Based Lateral Control of Longer and Heavier Commercial Vehicles

   Författare :Maliheh Sadeghi Kati; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rearward Amplification; static output feedback; Commercial vehicles; LMI-based H ∞ synthesis; Dynamic Feed-forward; Robust Control;

   Sammanfattning : Rapid growth in the transportation of goods has led to raised concerns about environmental effects, road freight traffic, and increased infrastructure usage. The increasing cost of fuel, and issues with congestions and gas emissions, make longer and heavier commercial vehicles (LHCVs) an attractive alter- native to conventional heavy vehicles. LÄS MER
