NBN ISO 19237:2021

This document specifies the concept of operation, minimum functionality, system requirements, system
interfaces, and test procedures for Pedestrian Detection and Collision Mitigation Systems (PDCMS). It
specifies the behaviours that are required for PDCMS, and the system test criteria necessary to verify
that a given implementation meets the requirements of this document. Implementation choices are left
to system designers wherever possible.
PDCMS reduce the severity of pedestrian collisions that cannot be avoided, and may reduce the likelihood
of fatality and severity of injury. PDCMS require information about range to pedestrians, motion of
pedestrians, motion of the subject vehicle (SV), driver commands and driver actions. PDCMS detect
pedestrians ahead of time, determine if detected pedestrians represent a hazardous condition, and warn
the driver if a hazard exists. PDCMS estimate if the driver has an adequate opportunity to respond to
the hazard. If there is inadequate time available for the driver to respond, and if appropriate criteria are
met, PDCMS determine that a collision is imminent. Based upon this assessment, PDCMS will activate
CWs and vehicle brakes to mitigate collision severity. This document, while not a collision avoidance
standard, does not preclude a manufacturer from implementing collision avoidance with PDCMS.
Systems that include other countermeasures such as evasive steering are not within the scope of this
document.
Responsibility for the safe operation of the vehicle remains with the driver.
This document applies to light duty passenger vehicles (see 3.6). It does not apply to other vehicle
categories such as heavy vehicles or motorcycles. PDCMS are not intended for off-road use.
