Road vehicles — Test method to evaluate the performance of autonomous emergency braking systems — Part 2: Car to pedestrian

This document specifies test methods to evaluate performance of the autonomous emergency braking system (AEBS) in car to pedestrian collision situations. Forward collision warning system (FCWS) is part of AEBS when it provides warning before braking intervention. Vehicle to pedestrian accidents occur when a vehicle under test (VUT) drives in straight line and either a pedestrian walks longitudinal on the same road or the pedestrian is approaching perpendicular the road. A system requiring a driver intervention is not in scope of this document. NOTE Depending on accidentology only a part of the scenarios can be used for an evaluation of performance.
