Road vehicles — Injury risk functions for advanced pedestrian legform impactor (aPLI) ISO/PWI TS 20459

Scope

This document provides definitions, symbols and injury probability functions (IPFs) for the thigh, leg and knee intended to be used with the advanced pedestrian legform impactor (aPLI), a standardized pedestrian legform impactor with an upper mass for pedestrian subsystem testing of road vehicles. They are applicable to impact tests using the aPLI at 11,1 m/s involving:
—    vehicles of category M1, except vehicles with a maximum mass above 2 500 kg and which are derived from N1 category vehicles and where the driver’s position, the R-point, is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1 100 mm;
—    vehicles of category N1, except where the driver’s position, the R-point, is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by maximum of 1 100 mm;
—    impacts to the bumper test area defined by References [1] and [2];
—    pedestrian subsystem tests involving use of a legform for the purpose of evaluating compliance with vehicle safety standards.
