Rigorous Safety Analysis and Design of ADAS and ADS: Implications on Tools

TL;DR

This paper discusses the challenges in defining, measuring, and designing safety for automated vehicles, emphasizing the need for rigor and introducing a tool that supports rigorous safety analysis aligned with standards.

Contribution

It highlights the importance of rigor in AV safety design and introduces EwQIMS, a tool supporting ISO 26262 compliance for functional safety analysis.

Findings

Identifies lack of rigor as a key issue in AV safety literature

Proposes organizational requirements for safety analysis tools

Introduces EwQIMS with ISO 26262 compliance features

Abstract

Currently, a major concern is the insufficient level of safety offered by commercial automated vehicles and/or services such self-driving vehicles, self-driving trucks, and robotaxis. Unfortunately, stakeholders do not agree on definitions and characterizations of what is meant by safety of automated vehicles including how to measure it and how to design for it. This paper sheds some light into the answers to important questions about the safety of automated vehicles. In addition, we identify rigor as a significant missing requirement in the current literature, we also provide a discussion of rigor in the design, development, and commercialization of automated vehicles. Furthermore, we discuss software tool requirements at the organizational level to support a rigorous approach for the analysis, design, and commercialization of automated vehicles. An ALM tool, EwQIMS, is introduced emphasizing its rigorous features of its functional safety module that implements much of the ISO 26262 standard.
