1. 1. Modelling and Simulation for Evaluation of Cooperative Intelligent Transport System Functions

   Författare :Maytheewat Aramrattana; Tony Ingemar Larsson; Jonas Jansson; Kenneth Lind; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative ITS; Autonomous driving; Traffic mixture; Simulation; Adaptive cruise control; Platooning electronic ; 23 Road: ITS och traffic; 23 Road: ITS och traffic;

   Sammanfattning : Future vehicles are expected to be equipped with wireless communication technology, that enables them to be “connected” to each others and road infrastructures. Complementing current autonomous vehicles and automated driving systems, the wireless communication allows the vehicles to interact, cooperate, and be aware of its surroundings beyond their own sensors’ range.

   Sammanfattning : During the last decades the road traffic has increased tremendously leading to congestion, safety issues and increased environmental impacts. As a result, many countries are continuously trying to find improvements and new solutions to solve these issues. LÄS MER

4. 3. Motion Planning and Control of Automated Vehicles in Critical Situations

   Författare :Lars Svensson; Martin Törngren; Lei Feng; Anna Pernestål Brenden; Christian Gerdes; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Sammanfattning : The road traffic environment is inherently uncertain and unpredictable. An automated vehicle (AV) deployed in such an environment will eventually experience unforeseen critical situations, i.e., situations in which the probability of having an accident is rapidly increased compared to a nominal driving situation.

5. 4. Controlling over-actuated road vehicles during failure conditions

   Författare :Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. LÄS MER

7. 5. Funktionsentreprenad Brounderhåll : en pilotstudie i Uppsala län

   Författare :Hans-Åke Mattsson; Håkan Sundquist; Ove Lagerquist; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; funktionsentreprenad; brounderhåll; bridge; manintenance; function; contract; Building engineering; Byggnadsteknik;

   Sammanfattning : Before 1992 the Swedish Road Administration (SRA) carried out all bridge maintenance and minor repair for all bridges in Sweden by themselves. The bridge maintenance crew in a county consisted typically of 3-6 workers and a bridge-engineer. LÄS MER
