Book excerpt: Die Elektronik und die Informatik wird in den nächsten Jahrzehnten einen immer höheren Stellenwert im Bereich der Fahrzeugsicherheit einnehmen. Neue Sensoren zur Umweltwahrnehmung werden die Fahrzeuge in die Lage versetzen angemessen auf die aktuelle Verkehrssituation zu reagieren. Es wird erwartet, dass aktive Sicherheitssysteme, wie beispielsweise die automatische Notbremsung, Fußgänger- und Radfahrererkennung und Funktionen zur Unfallvermeidung, die Anzahl tödlicher Verkehrsunfälle weiter zurückgehen lassen werden. Dabei besteht die Herausforderung darin, die neuen Sicherheitsfunktionen in ein System zu integrieren, dass bereits heute hochkomplex und vernetzt ist. Entstehen werden Echtzeitsysteme, die aus hochintegrierten Subsystemen bestehen werden. In dieser Dissertation werden Methoden entwickelt, um die Auslegung derartiger Steuergeräte in frühen Entwicklungsphasen abzusichern. Mithilfe von Modelltransformationen sowie simulativer und formaler Methoden werden verschiedene Architekturkonzepte aus den Perspektiven effektiver Umfeldwahrnehmung, funktionaler Sicherheit und Echtzeitfähigkeit betrachtet und bewertet. Von besonderer Bedeutung sind hierbei die Echtzeiteigenschaften der Softwareanteile der Sicherheitsfunktionen. Alle entwickelten Methoden wurden im Rahmen einer Forschungskooperation zwischen der Universität Erlangen-Nürnberg und der AUDI AG angewendet. Folgende Erkenntnisse konnten unter Anderem gewonnen werden: • Die Fusion von Objektlisten verschiedenartiger Sensoren ist aus Kosten-Nutzen-Sicht zu bevorzugen. • Modellbasierte Sicherheitsanalysen bieten sich insbesondere in frühen Entwicklungsphasen an, den Entwicklungsprozess zu unterstützen. • Für die Echtzeitanalyse von Steuergeräten sind exakte Algorithmen erforderlich, die in der Lage sind die kritischen Systemzustände zu visualisieren. • Die Simulation der Softwaretasks ist ein wichtiger Bestandteil der Analyse und ist erforderlich, um die dynamischen Effekte des Systems zu verstehen, sowie die Relevanz der kritischen Systemzustände einschätzen zu können. • Der Ansatz der modellgetriebenen Entwicklung ist besonders praktikabel in frühen Phasen der Systementwicklung, wenn man die Verallgemeinerung der Erkenntnisse unter Berücksichtigung des Abstraktionsgrades der Systemmodelle und der Eingabeparametermodelle durchführt. Durch die durchgeführten Analysen wurden Jahre vor der Serienproduktion, und Monate bevor erste Entwicklungsmuster zur Verfügung standen, an verschiedenen Stellen Engpässe in der Leistungsfähigkeit der Architekturkonzepte gefunden. Aufgrund der guten Zusammenarbeit zwischen OEM, Lieferant und Wissenschaft wurden neue Entwicklungsprozesse ins Leben gerufen und implementiert. Sowohl momentane als auch zukünftige Sicherheitssysteme profitieren von den entwickelten Methoden und werden die Basis bieten können um effiziente und effektive Funktionen der Fahrzeugsicherheit umsetzen zu können.

Available in PDF, EPUB and Kindle. Book excerpt: Thetopicof“Model-BasedEngineeringofReal-TimeEmbeddedSystems”brings together a challenging problem domain (real-time embedded systems) and a - lution domain (model-based engineering). It is also at the forefrontof integrated software and systems engineering, as software in this problem domain is an essential tool for system implementation and integration. Today, real-time - bedded software plays a crucial role in most advanced technical systems such as airplanes, mobile phones, and cars, and has become the main driver and - cilitator for innovation. Development, evolution, veri?cation, con?guration, and maintenance of embedded and distributed software nowadays are often serious challenges as drastic increases in complexity can be observed in practice. Model-based engineering in general, and model-based software development in particular, advocates the notion of using models throughout the development and life-cycle of an engineered system. Model-based software engineering re- forces this notion by promoting models not only as the tool of abstraction, but also as the tool for veri?cation, implementation, testing, and maintenance. The application of such model-based engineering techniques to embedded real-time systems appears to be a good candidate to tackle some of the problems arising in the problem domain.

Download or read book Analysis Architectures and Modelling of Embedded Systems written by Achim Rettberg and published by Springer. This book was released on 2009-09-19 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the technical program of the International Embedded Systems Symposium (IESS) 2009. Timely topics, techniques and trends in embedded system design are covered by the chapters in this volume, including modelling, simulation, verification, test, scheduling, platforms and processors. Particular emphasis is paid to automotive systems and wireless sensor networks. Sets of actual case studies in the area of embedded system design are also included. Over recent years, embedded systems have gained an enormous amount of proce- ing power and functionality and now enter numerous application areas, due to the fact that many of the formerly external components can now be integrated into a single System-on-Chip. This tendency has resulted in a dramatic reduction in the size and cost of embedded systems. As a unique technology, the design of embedded systems is an essential element of many innovations. Embedded systems meet their performance goals, including real-time constraints, through a combination of special-purpose hardware and software components tailored to the system requirements. Both the development of new features and the reuse of existing intellectual property components are essential to keeping up with ever more demanding customer requirements. Furthermore, design complexities are steadily growing with an increasing number of components that have to cooperate properly. Embedded system designers have to cope with multiple goals and constraints simul- neously, including timing, power, reliability, dependability, maintenance, packaging and, last but not least, price.

Download or read book Model Driven Dependability Assessment of Software Systems written by Simona Bernardi and published by Springer Science & Business Media. This book was released on 2013-10-22 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, a major challenge for researchers working on modeling and evaluation of computer-based systems has been the assessment of system Non Functional Properties (NFP) such as performance, scalability, dependability and security. In this book, the authors present cutting-edge model-driven techniques for modeling and analysis of software dependability. Most of them are based on the use of UML as software specification language. From the software system specification point of view, such techniques exploit the standard extension mechanisms of UML (i.e., UML profiling). UML profiles enable software engineers to add non-functional properties to the software model, in addition to the functional ones. The authors detail the state of the art on UML profile proposals for dependability specification and rigorously describe the trade-off they accomplish. The focus is mainly on RAMS (reliability, availability, maintainability and safety) properties. Among the existing profiles, they emphasize the DAM (Dependability Analysis and Modeling) profile, which attempts to unify, under a common umbrella, the previous UML profiles from literature, providing capabilities for dependability specification and analysis. In addition, they describe two prominent model-to-model transformation techniques, which support the generation of the analysis model and allow for further assessment of different RAMS properties. Case studies from different domains are also presented, in order to provide practitioners with examples of how to apply the aforementioned techniques. Researchers and students will learn basic dependability concepts and how to model them using UML and its extensions. They will also gain insights into dependability analysis techniques through the use of appropriate modeling formalisms as well as of model-to-model transformation techniques for deriving dependability analysis models from UML specifications. Moreover, software practitioners will find a unified framework for the specification of dependability requirements and properties of UML, and will benefit from the detailed case studies.
