Der eingebettete Mehrkernprozessor wird als die Hardware-Plattform angesehen, welche den stetig steigenden Rechenanforderungen von Steuerungs-Software in Automobilen gerecht wird. Dieser verfügt über eine höhere Rechenleistung und verbraucht weniger Energie. Steuerungs-Software wird entsprechend dem AUTomotive Open System ARchitecture (AUTOSAR)- Standard entwickelt. Runnables, elementare Code-Abschnitte, bilden strukturiert in Software-Components angeordnet das funktionale Verhalten des Reglers ab. Bei der Migration auf Mehrkernprozessoren soll existierende Steuerungs-Software wiederverwendet werden. Gegenstand der Dissertation ist die Migration existierender AUTOSAR-Steuerungs-Software auf Mehrkernprozessorsteuergeräte. Zentrale Herausforderungen sind: 1) Datenabhängigkeiten zwischen Runnables müssen beachtet werden, was die erreichbare Parallelität einschränkt. 2) Der ursprüngliche Datenfluss und dessen Latenz müssen nachgebildet werden, um dasselbe funktionale Verhalten ohne aufwändige Validierung oder Tests zu erreichen. 3) Das Energiesparpotenzial des Prozessors soll genutzt werden. Auf Runnable-Ebene verteilt RunPar Runnables statt Tasks. Darüber hinaus wird die Parallelität durch das Konzept der Supertask erhöht. Diese gruppiert Runnables von nacheinander ausgeführten Tasks, deren Runnables anschließend mittels RunPar verteilt werden. Auf Task-Ebene entkoppelt Timed Implicit Communication (TIC) die Kommunikation zwischen Tasks, um die parallele Ausführung von produzierender und konsumierender Task zu ermöglichen. Ein Vergleich mit RunPar legt nahe, dass es sich bei Runnable- und Task-Ebenen-Parallelisierung um einander ergänzend einzusetzende Strategien handelt. Schließlich wird eine koordinierende Strategie vorgeschlagen, welche beide Parallelisierungsebenen kombiniert. Der Verarbeitungspfad von Sensor zu Aktuator wird explizit modelliert. Dies ermöglicht die Berücksichtigung der Latenz. Task-Perioden und Prozessortakt werden.

This volume contains papers presented at the NATO sponsored Advanced Research Workshop on "Software for Parallel Computation" held at the University of Calabria, Cosenza, Italy, from June 22 to June 26, 1992. The purpose of the workshop was to evaluate the current state-of-the-art of the software for parallel computation, identify the main factors inhibiting practical applications of parallel computers and suggest possible remedies. In particular it focused on parallel software, programming tools, and practical experience of using parallel computers for solving demanding problems. Critical issues relative to the practical use of parallel computing included: portability, reusability and debugging, parallelization of sequential programs, construction of parallel algorithms, and performance of parallel programs and systems. In addition to NATO, the principal sponsor, the following organizations provided a generous support for the workshop: CERFACS, France, C.I.R.A., Italy, C.N.R., Italy, University of Calabria, Italy, ALENIA, Italy, The Boeing Company, U.S.A., CISE, Italy, ENEL - D.S.R., Italy, Alliant Computer Systems, Bull RN Sud, Italy, Convex Computer, Digital Equipment Corporation, Rewlett Packard, Meiko Scientific, U.K., PARSYTEC Computer, Germany, TELMAT Informatique, France, Thinking Machines Corporation.

This book contains the papers presented at the 20th anniversary edition of the AMAA conference held in Brussels, Belgium in 2016. The theme of the conference was “Smart Systems for the Automobile of the Future”. The automobile is currently being reshaped at unprecedented pace. Automation and electrification are the two dominant megatrends which dramatically change the choice and design of components, systems, vehicular architectures and ultimately the way we use cars in the coming decades. Novel E/E architectures, vehicular connectivity and cloud services will be key to extending the perception and decision-making horizons of automated vehicles, to enable cooperative functions and a seamless digital user experience. The AMAA’s ongoing mission to detect novel trends in automotive ICT, electronics and smart systems and to discuss the technological implications is once again reflected in this volume. The book will be a valuable read for research experts and professionals in the automotive and smart systems industry but the book may also be beneficial for graduate students.

This book demonstrates the use of the optimization techniques that are becoming essential to meet the increasing stringency and variety of requirements for automotive systems. It shows the reader how to move away from earlier approaches, based on some degree of heuristics, to the use of more and more common systematic methods. Even systematic methods can be developed and applied in a large number of forms so the text collects contributions from across the theory, methods and real-world automotive applications of optimization. Greater fuel economy, significant reductions in permissible emissions, new drivability requirements and the generally increasing complexity of automotive systems are among the criteria that the contributing authors set themselves to meet. In many cases multiple and often conflicting requirements give rise to multi-objective constrained optimization problems which are also considered. Some of these problems fall into the domain of the traditional multi-disciplinary optimization applied to system, sub-system or component design parameters and is performed based on system models; others require applications of optimization directly to experimental systems to determine either optimal calibration or the optimal control trajectory/control law. Optimization and Optimal Control in Automotive Systems reflects the state-of-the-art in and promotes a comprehensive approach to optimization in automotive systems by addressing its different facets, by discussing basic methods and showing practical approaches and specific applications of optimization to design and control problems for automotive systems. The book will be of interest both to academic researchers, either studying optimization or who have links with the automotive industry and to industrially-based engineers and automotive designers.
