Safety of the Intended Functionality Concept Integration into a Validation Tool Suite

TL;DR

This paper presents a method for integrating the Safety of the Intended Functionality (SOTIF) process into an existing validation tool suite to improve scenario-based validation of complex ADAS and AD systems.

Contribution

It demonstrates how to adapt a validation tool suite to incorporate SOTIF, with practical examples to facilitate understanding of the integration process.

Findings

Successful integration of SOTIF into validation tools

Enhanced scenario-based validation capabilities

Guidelines for adapting validation processes

Abstract

Nowadays, the increasing complexity of Advanced Driver Assistance Systems (ADAS) and Automated Driving (AD) means that the industry must move towards a scenario-based approach to validation rather than relying on established technology-based methods. This new focus also requires the validation process to take into account Safety of the Intended Functionality (SOTIF), as many scenarios may trigger hazardous vehicle behaviour. Thus, this work demonstrates how the integration of the SOTIF process within an existing validation tool suite can be achieved. The necessary adaptations are explained with accompanying examples to aid comprehension of the approach.
