The traffic volume, even it is already dense, will increase further in the next years and so the number of the accidents, in which trucks are involved over proportionally. Stand alone safety systems (ABS, ESP) are distributed functions inside a vehicle, which communicate with each other, but not strongly integrated at the moment. Furthermore functions like steering and braking are not yet fully electronically controlled. There is still conventional mechanical actuator control in use, resulting in a lack of safety potential. The development of safety-critical systems is mainly driven by the social demand, that societies want to see safer, more reliable vehicles on the roads, which can also handle more complex situations than the human driver can. By the integration of modern electronic technologies and a well-implemented chassis control into an intelligent, fully electronically controlled power train the overall traffic safety and efficiency especially for trucks can be improved. By-wire technology offers both functional and design benefits, but their application in safety-critical systems, such as braking and steering, requires special care during the design and release process.

The use of software to control automotive safety critical functions, such as throttle, braking and steering has been increasing. The automotive industry has a need for safety analysis methods and design processes to ensure these systems function safely. Many current recommendations still focus on traditional methods, which worked well for electro-mechanical designs but are not adequate for software intensive complex systems. System Theoretic Accident Model and Process (STAMP) and the associated System Theoretic Process Analysis (STPA) method have been found to identify hazards for complex systems and can be effective earlier in the design process than current automotive techniques. The design of a complex safety-critical system will require many decisions that can potentially impact the system's safety. A safety analysis should be performed on the new design to understand any potential safety issues. Methods that can help identify where and how the change impacts the analysis would be a useful tool for designers and managers. This could reduce the amount of time needed to evaluate changes and to ensure the safety goals of the system are met. This thesis demonstrates managing design changes for the safety-guided design of an automotive safety-critical shift-by-wire system. The current safety related analysis methods and standards common to the automotive industry and the system engineering methods and research in the use of requirements traceability for impact analysis in engineering change management was reviewed. A procedure was proposed to identify the impact of design changes to the safety analysis performed with STPA. Suggested guidelines were proposed to identify the impact of the change on the safety analysis performed with STPA. It was shown how the impact of the design changes were incorporated into the STPA results to ensure safety constraints are managed with respect to these changes to maintain the safety controls of the system throughout the design process. Finally the feasibility of the procedure was demonstrated through the integration of the procedure with requirements traceability based on system engineering practices

Safety-critical systems, by definition those systems whose failure can cause catastrophic results for people, the environment, and the economy, are becoming increasingly complex both in their functionality and their interactions with the environment. Unfortunately, safety assessments are still largely done manually, a time-consuming and error-prone

What is exactly “Safety”? A safety system should be defined as a system that will not endanger human life or the environment. A safety-critical system requires utmost care in their specification and design in order to avoid possible errors in their implementation that should result in unexpected system’s behavior during his operating “life”. An inappropriate method could lead to loss of life, and will almost certainly result in financial penalties in the long run, whether because of loss of business or because the imposition of fines. Risks of this kind are usually managed with the methods and tools of the “safety engineering”. A life-critical system is designed to 9 lose less than one life per billion (10 ). Nowadays, computers are used at least an order of magnitude more in safety-critical applications compared to two decades ago. Increasingly electronic devices are being used in applications where their correct operation is vital to ensure the safety of the human life and the environment. These application ranging from the anti-lock braking systems (ABS) in automobiles, to the fly-by-wire aircrafts, to biomedical supports to the human care. Therefore, it is vital that electronic designers be aware of the safety implications of the systems they develop. State of the art electronic systems are increasingly adopting progr- mable devices for electronic applications on earthling system. In particular, the Field Programmable Gate Array (FPGA) devices are becoming very interesting due to their characteristics in terms of performance, dimensions and cost.

A one-stop reference guide to design for safety principles and applications Design for Safety (DfSa) provides design engineers and engineering managers with a range of tools and techniques for incorporating safety into the design process for complex systems. It explains how to design for maximum safe conditions and minimum risk of accidents. The book covers safety design practices, which will result in improved safety, fewer accidents, and substantial savings in life cycle costs for producers and users. Readers who apply DfSa principles can expect to have a dramatic improvement in the ability to compete in global markets. They will also find a wealth of design practices not covered in typical engineering books—allowing them to think outside the box when developing safety requirements. Design Safety is already a high demand field due to its importance to system design and will be even more vital for engineers in multiple design disciplines as more systems become increasingly complex and liabilities increase. Therefore, risk mitigation methods to design systems with safety features are becoming more important. Designing systems for safety has been a high priority for many safety-critical systems—especially in the aerospace and military industries. However, with the expansion of technological innovations into other market places, industries that had not previously considered safety design requirements are now using the technology in applications. Design for Safety: Covers trending topics and the latest technologies Provides ten paradigms for managing and designing systems for safety and uses them as guiding themes throughout the book Logically defines the parameters and concepts, sets the safety program and requirements, covers basic methodologies, investigates lessons from history, and addresses specialty topics within the topic of Design for Safety (DfSa) Supplements other books in the series on Quality and Reliability Engineering Design for Safety is an ideal book for new and experienced engineers and managers who are involved with design, testing, and maintenance of safety critical applications. It is also helpful for advanced undergraduate and postgraduate students in engineering. Design for Safety is the second in a series of “Design for” books. Design for Reliability was the first in the series with more planned for the future.
