About this book

The objective of this scientific work is to research, test and develop an approach and design a safety architecture for highly safe, available and autonomous systems with regard to functional safety using degradation concepts. A novel, safety-oriented 4oo6 sensor structure targeting functional safety aspects has been thoroughly scientifically investigated, developed and validated. This Sensor Safety 4oo6 structure represents a major challenge as it integrates innovative approaches to improve system safety. The new safety strategy for autonomous systems enables operation in different modes and offers flexibility and adaptability. The 4oo6 safety architecture analyzed and developed in the scientific study has a self-monitoring structure that enables early detection of faults. This ensures that both the safety and availability of the system are maintained in the long term.

The new Safety 4oo6 structure represents a new challenge, as such an architecture does not yet exist in the IEC 61508 safety standard or in DIN EN 61511. With this new architecture, a significantly higher level of safety and availability can be achieved.

Chapter 1. Introduction and Motivation

Abstract

Topics such as “autonomous driving” (AD) and “autonomous robots” (AR) have been an integral part of scientific discourse for many years now. Car manufacturers and suppliers have been working on these topics and the associated areas of technology for quite some time. Many (partially) autonomous systems are already firmly established in the current vehicle generations of the major car manufacturers.

Chapter 2. Ethics in the Field of Autonomous Driving

Abstract

Public awareness of autonomous driving continues to expand, as it is often mentioned in mass media coverage as a solution to many of our car-related traffic problems such as congestion, environmental pollution and (fatal) accidents. However, it is often not yet entirely clear what concrete possibilities and potential, but also what risks are associated with it and what challenges still need to be overcome. In order to achieve acceptance, i.e. an active willingness on the part of the population to drive autonomously, fears about risks are key, in addition to reliable tests of technological achievements.

Chapter 3. Standards, Regulations and Norms

Abstract

It is not uncommon to read about car recalls in the media. In 2015, for example, 1.66 million vehicles were recalled in Germany. One of the main reasons is the detection of a faulty function that poses a danger to the driver, passengers or road users and that must be rectified.

Chapter 4. Investigation and Contribution to the Analysis and Evaluation of Safe Processes in Critical Autonomous Systems to Increase System Reliability

Abstract

In order to be able to develop safe and autonomous systems in the automotive industry, stable and reliable verification methods are of fundamental importance. Modern vehicles are being equipped with ever more complex driver assistance functions, such as electronic stability program ESP, brake assist or lane keeping functions. However, as malfunctions of the relevant components cannot be completely ruled out, safety and fallback concepts must be provided in the event of a system failure.

Chapter 5. Contribution to and Analysis of Safe Collision Avoidance in the Danger Zone of Autonomous Mobile Systems

Abstract

In future, more effective medicines will mean a product that is specifically tailored to the patient. This ongoing trend in the pharmaceutical industry, by way of example, is commonly referred to as “personalized medicine”. Many personalized treatment concepts require a small quantity of a drug to be filled, packaged and delivered to the patient in a specific dose.

Chapter 6. Test System for Testing the New Safety Architecture—Validation and Verification

Abstract

A test system was developed and set up to test the practical suitability of various safety architectures. With the safety requirements, all safety maneuvers of the three degrees of freedom can be executed in the plane. The vehicle has a maximum speed of 2.7 m/s and a tare weight of approximately 20 kg.

Chapter 7. Outlook and Evaluation

Abstract

This work focused on a specific environment, knowing full well that the results can be applied to numerous other areas with very little change.
