About this book

Bülent Sari deals with the various fail-operational safety architecture methods developed with consideration of domain ECUs containing multicore processors and describes the model-driven approaches for the development of the safety lifecycle and the automated DFA. The methods presented in this study provide fail-operational system architecture and safety architecture for both conventional domains such as powertrains and for ADAS/AD systems in relation to the processing chain from sensors to actuators.

​About the Author:

Bülent Sari works as a functional safety expert for autonomous driving projects. His doctoral thesis was supervised at the Institute of Internal Combustion Engines and Automotive Engineering, University of Stuttgart, Germany. He is a technical lead for not only functional safety in vehicles, but also for SOTIF, embracing the ISO 26262 standard as well as ISO PAS 21448. In this role, he coordinates and organizes the safety case execution of several product groups within different divisions of ZF.

Chapter 1. Introduction

Abstract
According to the global status report on road safety [12], 1.2 million people die each year due to traffic accidents around the world. Driver error is the cause of 94 % of the accidents which occur in the USA [11]. Of these driver-related critical errors, 41 % are recognition errors, 33 % are decision errors, 11 % are performance errors and 7 % are non-performance errors (sleep, etc.).

Chapter 2. State of the Art

Abstract
Safety is becoming more important with the increasing level of safety-related E/E Systems built into cars. The increasing functionality of vehicle systems through the electrification of the powertrain and autonomous driving technology leads to more complexity in the design of the system, hardware, software and safety architecture. To handle this increased complexity and develop the safer systems systematically, functional safety standards are being developed.

Chapter 3. Fail-operational Safety Architecture for ADAS/AD Systems

Abstract
The self-driving technology has been developing very rapidly in the last few years. Most of the automotive companies want to launch their autonomous vehicles with SAE level 4 at the beginning of 2020, but there are still some key technological challenges to solve [28, 29]. These challenges include increasing the safety and availability through a proper fail-operational system design.

Chapter 4. Model-driven Approaches for ISO 26262 Work Products and DFA

Abstract
This chapter presents two innovative approaches. The first approach describes the model-based development of ISO 26262 work products. The second approach concerns the model-based DFA which is required by ISO 26262 for the application of ASIL decomposition.
