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.

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.

A Clear Outline of Current Methods for Designing and Implementing Automotive Systems Highlighting requirements, technologies, and business models, the Automotive Embedded Systems Handbook provides a comprehensive overview of existing and future automotive electronic systems. It presents state-of-the-art methodological and technical solutions in the areas of in-vehicle architectures, multipartner development processes, software engineering methods, embedded communications, and safety and dependability assessment. Divided into four parts, the book begins with an introduction to the design constraints of automotive-embedded systems. It also examines AUTOSAR as the emerging de facto standard and looks at how key technologies, such as sensors and wireless networks, will facilitate the conception of partially and fully autonomous vehicles. The next section focuses on networks and protocols, including CAN, LIN, FlexRay, and TTCAN. The third part explores the design processes of electronic embedded systems, along with new design methodologies, such as the virtual platform. The final section presents validation and verification techniques relating to safety issues. Providing domain-specific solutions to various technical challenges, this handbook serves as a reliable, complete, and well-documented source of information on automotive embedded systems.

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.
