Road vehicles — Test devices for target vehicles, vulnerable road users and other objects, for assessment of active safety functions — Part 5: Requirements for powered two-wheeler targets

This document specifies performance requirements for surrogate targets used to assess the system detection and activation performance of active safety systems. This document specifies the properties of an omni-directional multi-purpose powered two-wheeler (PTW) target for assessment of interaction in a variety of traffic scenarios. This document specifies the properties of a PTW target (PTWT) representing a powered two-wheeler in terms of size, shape, reflection properties, etc. for testing purposes. This document addresses the detection requirements for a PTWT in terms of sensing technologies commonly in use at the time of publication of this document, and where possible, anticipated future sensing technologies. It also addresses methodologies to verify the target response properties to these sensors, as well as performance requirements for the target carrier. The PTWTs specified in this document reflect two-wheeled vehicles corresponding to UN Category L31) and to UN Category L12), with the restrictions that the vehicle is not intended for human propulsion (for example, pedalling) and its two wheels are inline. This document also addresses requirements for motion and positioning during test for PTWT including target carrier system. This document does not address the test procedures in terms of speeds, positions or timing of events. Performance criteria for the active safety system are also not addressed. 1) The vehicle categories are defined in Consolidated Resolution on the Construction of Vehicles (R.E.3): https://www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29resolutions.html . 2) See https://www.unece.org/trans/main/wp29/wp29wgs/wp29gen/wp29resolutions.html .

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.
