Passenger cars -- Test track for a severe lane-change manoeuvre

This document specifies the dimensions of the test track for a closed-loop test method to subjectively determine a double lane-change which is one part of the vehicle dynamics and road-holding ability of passenger cars. It is applicable to passenger cars as defined in ISO 3833. It is also applicable to light commercial vehicles up to a gross vehicle mass of 3,5 t.

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

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

expressions related to conformity assessment, as well as information about ISO's adherence to the WTO

principles in the Technical Barriers to Trade (TBT) see www .iso .org/iso/foreword .html.

This document has been prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee

SC 33, Vehicle dynamics and chassis components.

This second edition cancels and replaces the first edition (ISO 3888-1:1999), which has been technically

revised. The main changes compared to the previous edition are as follows:
— Recognizing regenerative braking and active control systems.

Introduction

The main purpose of this document is to provide repeatable and discriminatory test results.

The dynamic behaviour of a road vehicle is a very important aspect of active vehicle safety. Any given

vehicle, together with its driver and the prevailing environment, constitutes a closed-loop system that

is unique. The task of evaluating the dynamic behaviour is therefore very difficult since the significant

interactions of these driver-vehicle-environment elements are each complex in themselves. A complete

and accurate description of the behaviour of the road vehicle involves information obtained from a

number of different tests.

Since this test method quantifies only one small part of the complete vehicle handling characteristics,

the results of these tests can only be considered significant for a correspondingly small part of the

overall dynamic behaviour.

Moreover, insufficient knowledge is available concerning the relationship between overall vehicle

dynamic properties and accident avoidance. Acquiring sufficient and reliable data on the correlation

between accident avoidance and vehicle dynamic properties in general and the results of these tests in

particular involves a substantial amount of work. Consequently, any application of this test method for

regulation purposes will involve proven correlation between test results and accident statistics.

Annex A provides further information on the test method.
