About Course

The course is divided into two main chapters:

– Introduction

– Basics

– ISO 21448 Clauses

Chapter 1: Introduction

Includes an introduction of the course creator and provides a motivation lecture, why Safety of the intented functionality (SOTIF) is an important topic in the automotive industry nowadays.

Chapter 2: Basics

The chapter provides information on history and basic terms and definitions related to SOTIF. Also legal aspects are discussed in the chapter.

Chapter 3: ISO 21448

The chapter includes all chapters of the SOTIF standard ISO 21448 and explains the most important aspects of the chapters step by step.

The following chapters are covered by the course:

– Clause 4: Oveview and organization of SOTIF activities

The clause provides an overview of the most important aspects to be considered at the organizational level. For example the consideration of SOTIF principles and Management of SOTIF activities and supporting processes.

– Clause 5: Specification and design

The clause focuses on important aspect to be considered for specification of the functionality and the design.

– Clause 6: Identification and evaluation hazards

This clause focuses on the identification of hazards, evaluation of the resulting risk and the specification of acceptance criteria for the residual risk.

– Clause 7: Identification and evaluation of potential functional insufficiencies and potential triggering conditions

This clause provides an overview of the relation of potential functional insufficiencies and triggering conditions. And how harm can be a result.

– Clause 8: Functional modifications addressing SOTIF-related risks

This clause describes the possible options for a risk reduction in case the resulting risk is above an acceptable limit.

– Clause 9: Definition of the verification and validation strategy

The clause describes the aspects to be considered in a verification and validation strategy. Also how to derive validation targets based on the acceptance criteria is desrcribed.

– Clause 10: Evaluation of known scenarios

This clause described the evaluation of known scenarios and related methods for sensing verification, planning algorithm verification, actuation verification and verification of the integrated system.

– Clause 11. Evaluation of unknown scenarios

This clause describes how to ensure that the residual risk die tu unknown scenarios is below the acceptable limit.

– Clause 12: Evaluation of the achievement of the SOTIF

This clause describes the possible recommendation for final release of the SOTIF

– Clause 13: Operation phase activities

This clause describes how to ensure SOTIF after release in case SOTIF related risks are identified during operation phase.

At the end you get an overview of the ISO 26262 structure, since the safety standard ISO 26262 is one of the most important references in the ISO 21448.
