Book Description
Picture this scenario: You're cruising down the highway, your hands lightly gripping the steering wheel, and your mind wandering in the symphony of your favorite songs. The sun's golden rays bathe your vehicle in warmth, creating the perfect driving experience. Yet, beneath this serene surface, a complex network of systems is diligently at work to ensure your safety. The brakes are ready to respond to your slightest command; airbags stand ready to deploy in milliseconds if the unexpected happens; and the engine hums along, reliably transporting you to your destination. This harmony, this dance of safety and technology, is precisely what functional safety in the automotive industry is all about. Functional safety is not an optional accessory; it's the foundation upon which the entire automotive world rests. The vehicles we drive today are marvels of modern engineering, packed with intricate electronics and software that optimize performance, enhance comfort, and increase fuel efficiency. However, this evolution brings an indispensable responsibility - ensuring that these sophisticated systems do not compromise our safety. This is where functional safety takes center stage.

Book Description
This book introduces the concept of software architecture as one of the cornerstones of software in modern cars. Following a historical overview of the evolution of software in modern cars and a discussion of the main challenges driving that evolution, Chapter 2 describes the main architectural styles of automotive software and their use in cars’ software. Chapter 3 details this further by presenting two modern architectural styles, i.e. centralized and federated software architectures. In Chapter 4, readers will find a description of the software development processes used to develop software on the car manufacturers’ side. Chapter 5 then introduces AUTOSAR – an important standard in automotive software. Chapter 6 goes beyond simple architecture and describes the detailed design process for automotive software using Simulink, helping readers to understand how detailed design links to high-level design. The new chapter 7 reports on how machine learning is exploited in automotive software e.g. for image recognition and how both on-board and off-board learning are applied. Next, Chapter 8 presents a method for assessing the quality of the architecture – ATAM (Architecture Trade-off Analysis Method) – and provides a sample assessment, while Chapter 9 presents an alternative way of assessing the architecture, namely by using quantitative measures and indicators. Subsequently Chapter 10 dives deeper into one of the specific properties discussed in Chapter 8 – safety – and details an important standard in that area, the ISO/IEC 26262 norm. Lastly, Chapter 11 presents a set of future trends that are currently emerging and have the potential to shape automotive software engineering in the coming years. This book explores the concept of software architecture for modern cars and is intended for both beginning and advanced software designers. It mainly aims at two different groups of audience – professionals working with automotive software who need to understand concepts related to automotive architectures, and students of software engineering or related fields who need to understand the specifics of automotive software to be able to construct cars or their components. Accordingly, the book also contains a wealth of real-world examples illustrating the concepts discussed and requires no prior background in the automotive domain. Compared to the first edition, besides the two new chapters 3 and 7 there are considerable updates in chapters 5 and 8 especially.

Book Description
This book highlights the current challenges for engineers involved in product development and the associated changes in procedure they make necessary. Methods for systematically analyzing the requirements for safety and security mechanisms are described using examples of how they are implemented in software and hardware, and how their effectiveness can be demonstrated in terms of functional and design safety are discussed. Given today’s new E-mobility and automated driving approaches, new challenges are arising and further issues concerning “Road Vehicle Safety” and “Road Traffic Safety” have to be resolved. To address the growing complexity of vehicle functions, as well as the increasing need to accommodate interdisciplinary project teams, previous development approaches now have to be reconsidered, and system engineering approaches and proven management systems need to be supplemented or wholly redefined. The book presents a continuous system development process, starting with the basic requirements of quality management and continuing until the release of a vehicle and its components for road use. Attention is paid to the necessary definition of the respective development item, the threat-, hazard- and risk analysis, safety concepts and their relation to architecture development, while the book also addresses the aspects of product realization in mechanics, electronics and software as well as for subsequent testing, verification, integration and validation phases. In November 2011, requirements for the Functional Safety (FuSa) of road vehicles were first published in ISO 26262. The processes and methods described here are intended to show developers how vehicle systems can be implemented according to ISO 26262, so that their compliance with the relevant standards can be demonstrated as part of a safety case, including audits, reviews and assessments.

Book Description
The need to specify quantitative safety targets for overall systems, and for their separate protection sub-systems, has grown rapidly over the last ten years. This feature has become known as Functional Safety and numerous standards and guidelines have emerged, most of which incorporate the idea of safety-integrity levels (SILs). The quantified target (either a failure rate or a probability of failure on demand) determines which of four target SILs is called for. The higher the SIL then the more onerous the qualitative requirements to be observed during the life-cycle. Thus safety-integrity is addressed from two points of view: Meeting the numerical failure rate target Meeting the qualitative requirements for the SIL in question The IEC Standard 61508, Functional Safety, has become the umbrella document under which most other guidelines are now regarded as "2nd tier guidance." Functional Safety: A Straightforward Guide to IEC 61508 and Related Standards is based primarily on understanding that standard and provides a straightforward guide to the essentials. Dr David J Smith BSc, PhD, CEng, FIEE, HonFSaRS, FIQA, MIGasE has been directly concerned with reliability, safety and software quality for 30 years. He has written a number of books on the subject as well as numerous papers. His PhD thesis was on the subject of reliability prediction accuracy and common cause failure. He chairs the IGasE panel which develops its guidelines on safety-related systems (now in its third edition). He has also made contributions to IEC 61508. Kenneth G L Simpson MPhil, FIEE, FInstMC, MIGasE has been associated with safety-related systems design and also with their assessment for 25 years. He is a member of the IEC 61508 drafting committee and also of the I Gas E panel which writes the gas industry guidance. Following a career in aerospace, Ken has spent 20 years in the control system industry and is a Director of Silvertech International plc, a leading designer of safety and control systems. He has written a number of papers on the topic and gives frequent talks. Explains the practical and management issues raised by the important new international standard for safety-critical systems Guidance on self-assessment could save you thousands in consultancy fees
