Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Introduction

Standardization of service role and functional model is necessary for the introduction of low-speed automated driving systems (LSADS) to support safe and efficient mobility used as a means of moving people, goods and services in urban and rural areas.

ISO 22737 and ISO 7856 describe vehicle driving supports and do not cover the requirements of service role and functional model covering infrastructure facilities. Many business use cases regarding low-speed automated driving system (LSADS) services are currently emerging and many more variations are coming to be deployed. Various role and functional model presentation methodologies are currently in use and there is therefore a need for a common understandable role and functional model presentation baseline standard.

ISO/TS 5255-1 defines a common LSAD system service role and functional model presentation guidelines. Future emerging business cases can refer to ISO/TS 5255-1 as a baseline document which does not hinder the development of future business cases, but instead assists them.

This document focuses on safety operation gap analysis and serves as a baseline document describing which supplemental roles need be considered to take a safe operation lead in addition to the roles described in ISO/TS 5255-1. The purpose of this document is to assist in the introduction of LSADS, including infrastructure facilities to support mobility in urban and rural areas.

1 Scope

This document:

• examines and analyses the safety environment for low-speed automated driving services (LSADS);
• describes the safety role supplement to the functional model described in ISO/TS 5255-1;
• describes the supplemental safety points for LSADS;
• describes role for the functional model of service applications for LSADS.

This document can contribute to the development of future automated driving system service safety requirement use cases, other than the one described in ISO/TS 5255-1.

This document is applicable to services using LSADS-equipped vehicles only.

In-vehicle control system is not in scope of this document.
