ISO 19206-5:2025

Overview

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 is an international standard specifying the performance requirements for surrogate targets that represent powered two-wheelers (PTWs), such as motorcycles and scooters, during active safety system testing. This standard, developed by ISO, focuses on the properties, detection, and verification of powered two-wheeler targets (PTWTs) to ensure reliable, reproducible results in various traffic scenarios. PTWTs as described in this document are designed to mimic real PTWs in terms of size, shape, and reflective properties while considering current and future sensing technologies.

Key Topics

• PTW Target Specifications
  • Addresses UN Category L1 and L3 powered two-wheelers (excluding human-propelled vehicles).
  • Defines representative PTWTs with strict tolerances to provide reproducible active safety testing.
  • Establishes requirements for physical construction, including symmetry, typical shapes, and critical components such as wheels, handlebars, mirrors, and lights. The target should also include a realistic rider with a helmet.
• Sensor Detection Requirements
  • Specifies PTWT properties for proper detection by various sensor technologies, including optical (camera, LIDAR), radar, far-infrared (thermal), and ultrasonic sensors.
  • Details methodologies for verifying PTWT responsiveness to these sensors and accounts for anticipated advancements in detection technology.
  • Requirements include stability under environmental conditions (temperature ranges, wind), and realistic behavior under aerodynamic effects.
• Motion and Positioning
  • Sets requirements for PTWT movement and target carrier systems, including speed classes (up to and beyond 80 km/h), acceleration/deceleration capabilities, and positioning tolerances for repeatability.
  • Outlines calibration and field verification processes to ensure ongoing compliance with detection and motion requirements.

Applications

• Active Safety System Testing
  • Essential for automotive manufacturers, testing laboratories, and ADAS (Advanced Driver Assistance Systems) developers who need reliable surrogate PTW targets to test system detection and activation.
  • Supports type approval, regulatory compliance, and consumer safety evaluations by providing robust, comparable, and reproducible test frameworks.
• ADAS and Automated Driving Development
  • Enables validation and improvement of active safety systems, including emergency braking, collision avoidance, and vulnerable road user detection, enhancing road safety for motorcyclists and other PTW users.
• Research and Development
  • Applicable for sensor and system developers to benchmark detection capabilities across multiple sensor types and refine algorithms for improved performance in real-world traffic scenarios featuring powered two-wheelers.

Related Standards

• ISO 19206 Series: This is part of the broader ISO 19206 series, which addresses test device requirements for various types of vehicles and vulnerable road users.
• UNECE Regulations: PTWT classifications reference vehicle categories as defined in the Consolidated Resolution on the Construction of Vehicles (R.E.3) by UNECE.
• ISO 8855: Defines vocabulary related to vehicle dynamics and road-holding ability, including coordinate systems for test devices.
• ISO 8608: Specifies the reporting of measured data on mechanical vibration and road surface profiles, relevant for defining road surfaces in testing.

ISO 19206-5:2025 provides a standardized foundation for designing, verifying, and employing powered two-wheeler surrogate targets in active safety testing. This improves the safety and reliability of advanced driver assistance systems and helps the automotive industry meet international expectations for testing repeatability and cross-comparability, ultimately advancing road safety for all users.
