Full title and description

Road vehicles — Test devices for target vehicles, vulnerable road users and other objects, for assessment of active safety functions — Part 4: Requirements for bicyclist targets. This International Standard specifies properties and performance requirements for a bicyclist target (BT) that represents a human bicyclist in terms of shape, movement, reflection properties and related characteristics for use when assessing detection and activation performance of active safety systems.

Abstract

ISO 19206-4:2020 defines the physical, optical, radar and thermal response properties, motion and positioning requirements, and verification methodologies for surrogate bicyclist targets used in active safety system testing. The document establishes detection-related requirements for commonly used sensing technologies (and anticipates future sensing approaches) and specifies test-target carrier performance requirements; it does not itself define test procedures, speeds, positions or system performance criteria.

Scope

This document specifies the properties and performance requirements of a bicyclist target representative of human bicyclists (including electrically assisted pedal bicycles/pedelecs) for testing active safety systems. It covers target size and posture, sensor-recognition characteristics (optical, radar, thermal), calibration and verification methods, motion and target-carrier positioning requirements, robustness and safety considerations. The standard does not prescribe specific test procedures, timing, speeds or system performance pass/fail criteria.

Key topics and requirements

• Specification of bicyclist target dimensions, postures and articulation (adult and child profiles in normative annexes).
• Optical/visual characteristics and reference measurements for colour, clothing and reflectivity to support camera-based systems.
• Radar-related requirements including radar cross section references and micro-Doppler considerations for rotating wheels and pedalling.
• Thermal characteristics and reference measurements for long-wave infrared (thermal) sensing systems.
• Calibration, verification and measurement methods (laboratory and field verification) for target properties and sensor responses.
• Requirements for motion and positioning of the BT and its carrier: longitudinal, lateral and vertical positioning, heading and speed ranges, and allowed accelerations.
• Safety, repairability, environmental and robustness requirements for the target and carrier systems.
• Normative and informative annexes covering dimensions, sensor-specific recognition properties, measurement equipment, articulation and example interfaces between target carrier and bicycle.

Typical use and users

Used by automotive manufacturers (OEMs), ADAS/automated driving system developers, test laboratories, certification bodies, design and validation engineers, and research organisations to evaluate and validate sensor detection performance and to verify test-target behaviour during active safety assessments. Regulatory or standards-based test programs and suppliers of physical target devices and target carriers also rely on this standard when designing and building test surrogates.

Related standards

ISO 19206-4 is part of the ISO 19206 series addressing test devices for targets and vulnerable road users. Related documents include: ISO 19206-1 (requirements for passenger vehicle rear-end targets), ISO 19206-2 (requirements for pedestrian targets), ISO 19206-3 (requirements for passenger vehicle 3D targets), and other parts/technical specifications in the series that define additional target types and procedures. Several parts (and related test procedures such as ISO 19237) provide complementary guidance for using surrogate targets in active safety testing.
