Road vehicles — Test method to evaluate the performance of acceleration control pedal error (ACPE) — Part 1: Car-to-car from standstill

Scope

This document specifies test methods to evaluate the behaviour of a vehicle equipped with an acceleration control pedal error (ACPE) system according to ISO/PAS 19486. Those forward and reverse accidents occur during a straight-line acceleration when the vehicle under test (VUT) accelerates due to driver misapplication of accelerator pedal instead of intended brake pedal. This document is limited to ACPE systems of light vehicles only classified in UN-ECE (TRANS/WP.29/1045) Vehicle: “Category 1-1 vehicle” and does not apply to such devices installed in vehicles of other categories, such as heavy vehicles or motorcycles. This document focuses on an important part of the vehicle behaviour during these collision scenarios, which is the capacity to avoid or mitigate the collision especially to the other vehicle.
