ISO DIS 19237

Description / Abstract: This International Standard 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 behaviors that are required for PDCMS, and the system test criteria necessary to verify that a given implementation meets the requirements of this International Standard. Implementation choices are left to system designers, wherever possible.

Pedestrian Detection and Collision Mitigation Systems (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, driver commands and driver actions. PDCMS detect pedestrians ahead, determine if detected pedestrians represent a hazardous condition, and warn the driver if a hazard exists. They 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, the PDCMS will activate collision warnings and vehicle brakes to mitigate collision severity. The PDCMS standard, while not a collision avoidance standard, does not preclude a manufacturer from implementing collision avoidance with a PDCMS system.

Systems that include other countermeasures such as evasive steering are not in the scope of this standard.

Responsibility for the safe operation of the vehicle remains with the driver.

The standard applies to light duty passenger vehicles (See 3.8). The standard does not apply to heavy vehicles or motorcycles. These systems are not intended for off-road use.
