1. 21. Conceptual design of hydraulic systems for automotive engine applications : simulation, optimisation and testing

   Författare :Jochen Pohl; Nicola Nervegna; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : The main contribution of this thesis lies in the area of systems design, and especially of such systems that involve several engineering domains, so-called multidomain or heterogeneous systems. The design of these systems is concerned with a need for efficient tools, especially in the early conceptual phase of the development process. LÄS MER

3. 22. Residual Generation Methods for Fault Diagnosis with Automotive Applications

   Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

   Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

4. 23. Control of permanent-magnet synchronous machines in automotive applications

   Författare :Oskar Wallmark; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; electric vehicle; fault tolerance; hybrid electric vehicle; inverter; in-wheel motor; loss minimization; permanent-magnet synchronous machine; phase-locked loop; position estimation; sensorless control; vector control;

   Sammanfattning : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotive applications. Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly. LÄS MER

5. 24. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

   Författare :Gordon Kelly; KTH; []
   Nyckelord :Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

   Sammanfattning : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. LÄS MER

7. 25. Battery Integrated Modular Multilevel Converter Topologies for Automotive Applications

   Författare :Arvind Balachandran; Lars Eriksson; Tomas Uno Jonsson; Torbjörn Thiringer; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electric vehicles are rapidly developing in response to the need for increasing sustainable energy sources. The range and lifetime of an electric vehicle are limited by the battery pack. A pack comprises modules with several parallel and/or series-connected cells. LÄS MER
