ISO 19237:2017 PDF

Overview

ISO 19237:2017 - Intelligent transport systems - Pedestrian detection and collision mitigation systems (PDCMS) - Performance requirements and test procedures - defines the concept of operation, performance requirements, and test procedures for Pedestrian Detection and Collision Mitigation Systems (PDCMS) on light‑duty passenger vehicles. The standard sets the minimum functionality, system interfaces and verification criteria needed to demonstrate that a PDCMS implementation meets required behaviours for collision warning (CW) and emergency braking (EB) to reduce pedestrian injury severity.

Key topics and requirements

• Concept of operation: detection, hazard assessment, driver warning, response timing and countermeasure activation.
• Minimum functionality: detect pedestrians, estimate distance and relative velocity, determine vehicle motion, issue CWs, and initiate EB where appropriate.
• System behaviour: estimate driver response opportunity; if inadequate, declare collision imminent and apply countermeasures.
• Countermeasure control: automatic braking activation and modulation, brake‑light control, integration with ESC/ABS to maintain yaw stability and manage wheel slip.
• Human factors: provide driver information about system availability and permit driver override at any time.
• Operating envelope: applies to light duty passenger vehicles only (not heavy vehicles, motorcycles or off‑road use); includes system state model and operational speed ranges.
• Test procedures: detailed test setup and pass/fail criteria covering pedestrian test targets, driving surface, ambient illumination, vehicle pre‑conditioning and mass. The standard includes different test types (e.g., Type 1 and Type 2) with specified illuminance measurement methods and pass criteria.
• Normative references: cross‑references ISO 19206‑2 (pedestrian target devices), ISO 19476 (illuminance/luminance meter characterization) and relevant WP.29 regulations.

Applications and users

ISO 19237 is intended for:

• Automotive OEMs validating PDCMS design and integration.
• Tier‑1 suppliers (sensor manufacturers, control units, braking systems) developing compliant subsystems.
• Test houses and certification labs performing performance verification and homologation testing.
• Regulators and safety authorities referencing performance criteria for policy or type‑approval.
• R&D teams working on pedestrian safety, sensor fusion, ADAS and emergency braking systems.

Practical uses include system design verification, pre‑regulatory validation, conformance testing, and benchmarking of pedestrian detection and collision mitigation performance.

Related standards

• ISO 19206‑2 - requirements for pedestrian test devices (targets)
• ISO 19476 - characterization of illuminance and luminance meters
• WP.29 vehicle regulations (referenced for vehicle categories and regulatory alignment)

ISO 19237 supports pedestrian safety and ADAS reliability by providing clear performance and test‑procedure guidance for PDCMS implementations.
