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).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof.

Introduction

ADAS (advanced driver assistance systems) and active-safety systems are designed to support decision-making for the driver, extend the driver’s awareness of the traffic situation with advanced warnings, improve the behaviour of the vehicle and even take over vehicle control in an emergency situation. The goal is to completely avoid an accident or at least reduce the severity of an accident.

The surrogate target is an essential component in the evaluation of ADAS, active-safety functions and different levels of automated driving systems, in all situations where a collision with the target can occur.

To make test protocols more realistic, the multiple targets which are used for testing are put on a target carrier system which can move following pre-defined trajectories, speeds, etc.

The motion of this target carrier with the target are designed to accurately fulfil the specifications defined in the test protocols, which can be type approval tests, consumer tests (for example, Euro NCAP or other NCAP) or development tests. The dynamic performance of the target carrier system can be determined using the methods in this document.

The target carrier can be of a large or a smaller type according to the size of the target and other demands of the pre-defined tests.

The description of the tests is based on the current NCAP test protocols and can be adapted for future test protocols.

1 Scope

This document provides test methods to determine the properties and performance of target carriers, in combination with specified targets.

This document specifies how to validate the target carrier with target regarding the dynamic performance versus the requirements and tolerances specified in test protocols. The main characteristics validated in this document are the speed, yaw rate and lateral deviation.

This document does not address the test synchronization between the vehicle under test (VUT) and the target carrier with target.

This document does not address the detection characteristics of the target carrier with target.

NOTE Performance requirements of targets and properties related to detection by sensor systems are covered by other parts of the ISO 19206 series.
