Full title and description

ISO 19206-5:2025 — 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 standard specifies performance and physical properties for surrogate powered two‑wheeler targets (PTWT) used to evaluate detection and activation of active safety systems and automated driving functions.

Abstract

ISO 19206-5:2025 defines the properties, detection characteristics and verification methods for omni‑directional multi‑purpose powered two‑wheeler targets (PTWT). It covers size, shape, reflective and thermal properties, motion and positioning requirements, and performance requirements for the associated target carrier systems. The PTWTs are intended to represent powered two‑wheelers corresponding to UN categories L3 and L1 (non‑human‑propelled, inline wheels). The document addresses sensing technologies in common use at publication and anticipated future sensors, but does not specify test procedures (speeds, timing) or pass/fail criteria for the active safety system under test.

Scope

The standard specifies the required physical and performance attributes of powered two‑wheeler surrogate targets used to assess vehicle active safety functions and automated driving system sensing. It establishes target geometries, material and surface properties (radar, lidar, optical and thermal signatures), required dynamic behaviour and tolerances for motion/positioning when used with target carrier systems, and methods to verify those detection properties. It excludes the definition of test scenarios, speeds, timing of events and the performance acceptance criteria of the systems under test.

Key topics and requirements

• Definition of omni‑directional powered two‑wheeler target (PTWT) types representing UN Category L3 and L1 two‑wheelers (non‑human‑propelled, inline wheels).
• Physical dimensions and shape descriptions that produce representative radar, lidar, optical and thermal responses.
• Surface material and reflectivity specifications to ensure repeatable sensor detection.
• Requirements for mounting, target carrier interface and carrier performance tolerances relevant to PTWT motion and positioning.
• Detection‑response requirements described by sensor modality (radar, lidar, camera, thermal) and recommended verification methods.
• Procedures and measurement methods to verify target properties and conformity with specified signatures and dynamic behaviour.
• Notes and exclusions clarifying that test procedures (scenario timing, speeds) and system performance criteria are not covered by this part.

Typical use and users

This standard is used by automotive OEMs and vehicle manufacturers, ADAS/ADS developers, Tier‑1 sensor and test‑equipment suppliers, independent test laboratories and NCAP/regulatory test organisations, research institutes, and manufacturers of test surrogate targets and target‑carrier systems. It is applied when specifying, procuring, manufacturing or validating powered two‑wheeler targets for sensor and system evaluation.
