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).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

Introduction

Roadworthiness testing is a part of a wider regime designed to ensure that vehicles are kept in

a safe and environmentally acceptable condition during their use. This regime covers periodic

roadworthiness testing of vehicles and technical roadside inspections of vehicles used for commercial

road transport activities and provides a vehicle registration procedure allowing for the suspension of

a vehicle’s authorization to be used in road traffic where the vehicle constitutes an immediate risk to

road safety. Periodic testing is the main tool to ensure roadworthiness. Technical roadside inspections

of commercial vehicles are merely complementary to periodic testing.

An ePTI system list, which is defined in this document, summarizes ePTI-relevant systems and specifies

a defined name (system), a unique identifier (ePTI system identifier) and a description for each ePTI

system. All the definitions in this document refer to this ePTI system list.

The ISO 20730 series is based on the Open Systems Interconnection (OSI) basic reference model specified

[1] [3]

in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers.

When mapped on this model, the application protocol and data link framework requirements specified/

referenced in the ISO 20730 series are structured according to Figure 1.

Figure 1 illustrates a standard-based documentation concept, which consists of the following main

clusters:

— vehicle diagnostic communication framework: covers all relevant basic vehicle diagnostic

communication specifications of OSI layers 7, 6, and 5;

— vehicle diagnostic communication use case framework: covers the master specification, which

specifies use cases und requirements of subject matter of OSI layer 7;

— presentation layer framework: covers all data relevant specifications of OSI layer 6;

— conformance test plan: covers the conformance test plan requirements of the use cases and

communication requirements of OSI layers 7, 6, and 5;

— lower OSI layer framework: covers all vehicle diagnostic protocol standards of OSI layers 4, 3, 2, and

1, which are relevant and referenced by the use case specific standard.

5 Informative guidance for considering ePTI relevance

ePTI-relevant systems are all vehicle systems and components, that when not operating to their design

criteria, affect the safety of the vehicle. These are vehicle systems that perform at least one of the

following functions:
a) deceleration of the vehicle;
b) longitudinal, lateral and yaw stabilization of vehicle movements;
c) hold the vehicle stationary;
d) change of angle >3° on any steered wheel, while vehicle speed is ≥15 km/h;
2 © ISO 2021 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/FDIS 20730-3:2021(E)
e) adjustment of the intensity and/or direction of the road illumination;

f) change of the signal image of the vehicle lighting devices, while vehicle speed is ≥15 km/h;

g) protecting the survival space of road users;
h) adjustment of the behaviour of the suspension and shock absorbers;
i) monitoring and control of tyre air pressure;
j) adjustment of the aerodynamic devices;
k) high voltage electrical propulsion ≥60 V;
l) changes in visibility;
m) hazard warning and emergency related communication;

n) generation of external warning for, e.g. pedestrian attention in regard to electric vehicle;

o) adjustment of the vehicle height or tilt;
p) automatically controlled acceleration.
The criteria and definition should be updated as technology progresses.

EXAMPLE The “automatic emergency brake” vehicle system can perform the “deceleration” function and is

therefore an ePTI-relevant vehicle system.

ePTI-relevant system list

The ePTI-relevant systems are identified based on the functional criteria in Clause 5. Table A.1

specifies ePTI-relevantSystemIdentifier, ePTI-relevant system name, symbolic name and ePTI system

description. The symbolic names provide the possibility , for example, to make a unique reference

to diagnostic description information in case a diagnostic service is not yet implemented using the

ePTI-relevantSystemIdentifier as specified in this document. Symbolic names use the character set

[2]

ISO 8859-1 in the range of 30 to 39 (0, 1, … 9), 41 to 5A (A, B, … Z), and 5F (_).
