This book was released on 2012 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2008-10-10 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Managing Design Changes Using Safety guided Design for a Safety Critical Automotive System written by John Sgueglia and published by . This book was released on 2015 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Functional Safety for Embedded Systems written by Guoqi Xie and published by CRC Press. This book was released on 2023-06-28 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book uses automotive embedded systems as an example to introduce functional safety assurance and safety-aware cost optimization. The book explores functional safety assurance from the perspectives of verification, enhancement, and validation. The functional safety assurance methods implement a safe and efficient assurance system that integrates safety verification, enhancement, and validation. The assurance methods offered in this book could provide a reasonable and scientific theoretical basis for the subsequent formulation of automotive functional safety standards. The safety-aware cost optimization methods divide cost types according to the essential differences of various costs in system design and establish reasonable models based on different costs. The cost optimization methods provided in this book could give appropriate cost optimization solutions for the cost-sensitive automotive industry, thereby achieving effective cost management and control. Functional safety assurance methods and safety-aware cost optimization support each other and jointly build the architecture of functional safety design methodologies for automotive embedded systems. The work aspires to provide a relevant reference for students, researchers, engineers, and professionals working in this area or those interested in hardware cost optimization and development cost optimization design methods based on ensuring functional safety in general.

Available in PDF, EPUB and Kindle. Book excerpt: This book studies the design optimization, state estimation, and advanced control methods for cyber-physical vehicle systems (CPVS) and their applications in real-world automotive systems. First, in Chapter 1, key challenges and state-of-the-art of vehicle design and control in the context of cyber-physical systems are introduced. In Chapter 2, a cyber-physical system (CPS) based framework is proposed for high-level co-design optimization of the plant and controller parameters for CPVS, in view of vehicle's dynamic performance, drivability, and energy along with different driving styles. System description, requirements, constraints, optimization objectives, and methodology are investigated. In Chapter 3, an Artificial-Neural-Network-based estimation method is studied for accurate state estimation of CPVS. In Chapter 4, a high-precision controller is designed for a safety-critical CPVS. The detailed control synthesis and experimental validation are presented. The application results presented throughout the book validate the feasibility and effectiveness of the proposed theoretical methods of design, estimation, control, and optimization for cyber physical vehicle systems.

This book was released on 2004-09-09 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theimportanceofsafetyandsecurityisgrowingsteadily.Safetyisaqualityc- racteristic that traditionally has been considered to be important in embedded systems, and security is usually an essential property in business applications. There is certainly a tendency to use software-based solutions in safety-critical applications domains, which increases the importance of safety engineering te- niques. These include modelling and analysis techniques as well as appropriate processes and tools. And it is surely correct that the amount of con?dential data that require protection from unauthorized access is growing. Therefore, security is very important. On the one hand, the traditional motivations for addressing safety and security still exist, and their relevance has improved. On the other hand, safety and security requirements occur increasingly in the same system. At present, many software-based systems interact with technical equipment and they communicate, e.g., with users and other systems. Future systems will more and more interact with many other entities (technical systems, people, the en- ronment). In this situation, security problems may cause safety-related failures. It is thus necessary to address safety and security. It is furthermore required to take into account the interactions between these two properties.
