Road vehicles. Prospective safety performance assessment of pre-crash technology by virtual simulation – State-of-the-art and general method overview

Abstract

What is PD ISO/TR 21934‑1 about?  

PD ISO/TR 21934‑1 is part of the multi-series standard that describes the state-of-the-art of prospective methods for assessing the safety performance of vehicle-integrated active safety technologies by virtual simulation. PD ISO/TR 21934‑1 describes how prospective assessment of vehicle-integrated technologies provides a prediction on how advanced vehicle safety technology will perform on the roads in real traffic. The focus is on the assessment of the technology as a whole and not of single components of the technology (e.g., sensors). 
The described assessment approach is limited to “vehicle-integrated” technology and does not consider technologies operating off-board. The virtual simulation method per se is not limited to a certain vehicle type. The assessment approach discussed in this document focuses on accident avoidance and the technology’s contribution to the mitigation of the consequences. Safety technologies that act in the in-crash or the post-crash phase are not explicitly addressed by the method, although the output from prospective assessments of crash avoidance technologies can be considered as an important input to determine the overall consequences of a crash. 

Who is PD ISO/TR 21934‑1 for? 

PD ISO/TR 21934‑1 on prospective safety performance assessment of pre-crash technology by virtual simulation-state-of-the-art and general method overview is useful for: 

Vehicle manufacturers  

Vehicle testing facilities 

Consumer rating organisation 

Governmental organisation 

Insurer

Why should you use PD ISO/TR 21934‑1?  

In general, the assessment of active safety technologies requires the consideration of interaction with surrounding traffic as well as the host vehicle driver. These interactions increase the complexity of the assessment due to the high number of resulting variables. Consequently, for a comprehensive assessment, the technology’s safety performance is analyzed in a high number of test scenarios, to cover all relevant circumstances that affect the critical situation and crashes. The virtual simulation approach allows for running large numbers of test scenarios while offering a promising combination of safety performance, flexibility, reproducibility, and experimental control. 
PD ISO/TR 21934‑1 provides an overview on the state-of-the-art in the prospective assessment of pre-crash technology by virtual simulation. PD ISO/TR 21934‑1 focuses on the prospective assessment of traffic safety for vehicle-integrated technologies acting in the pre-crash phase by means of virtual simulation. PD ISO/TR 21934‑1 provide a state-of-the-art of safety performance assessment of pre-crash technology by virtual simulation and to identify commonalities and differences in currently used approaches. PD ISO/TR 21934‑1 focuses on accident avoidance and the technology’s contribution to the mitigation of the consequences. 
PD ISO/TR 21934‑1 determines the safety performance of a technology by means of comparing data from the baseline and treatment simulations based on a certain metric. The baseline for the assessment is the situation without the vehicle-integrate technology under assessment present.  © British Standards Institution 2022
