“…The MPDB test scheme is published in the EURO-NCAP 2020-2025 road map, and it is planned to include vehicle compatibility as a sub-item in the evaluation scoring system [5][6]; Japan also actively participates in vehicle collision compatibility research, and has conducted extensive technical exchanges with Europe and America: it is suggested that the combination test of full frontal crash test and second energy-absorbing structure (SEAS) be used for evaluation. When the load on SEAS reaches 100KN, the displacement of SEAS must be controlled within 400mm [7]. At the moment, China's collision regulations and C-NCAP test methods are primarily aimed at protecting vehicle occupants, but no research on its own aggression has been conducted.…”

In the frontal accident, vehicles with strong aggressiveness are an important factor in causing death or injury to vulnerable vehicles. To effectively evaluate the aggressiveness of vehicle frontal crash, the dynamic load values and distribution of vehicle frontal structures are collected using the load-cell wall. On this basis, evaluation intervals in the horizontal and vertical directions are established, and the standard deviation and negative deviation of collision loads were analyzed. Normalization is carried out to establish evaluation indices for horizontal and vertical load effects. The effectiveness of the evaluation indexes is verified through analysis of frontal collision tests on several vehicle models. The results showed that the vertical and horizontal collision energy transfer at the front end of the vehicle still needs to be strengthened.

“…Source: Royal Malaysia Police Traffic Branch, Bukit Aman Global road accident studies indicate that the severity of injuries due to frontal impact is the most relevant factor pertaining to car occupants' deaths (Johannsen et al, 2013). A frontimpact car accident (or normally referred to as a head-on collision) occurs when the front-end of two vehicles collide with each other.…”

Adult Occupant Protection (AOP) is a vital area of evaluation in all New Car Assessment Programs (NCAPs) around the globe. The primary objective of these new car assessment programs is to reduce road deaths by focusing on vehicle (pre-crash) safety features. Starting from the year 2017 until 2020, a single rating system has been introduced whereby AOP contributes 50% to the overall rating with a maximum of 36 points; split into three main domains including offset frontal test (OFT), side impact test (SIT) and head protection technology (HPT). However, the extent of OFT protection to car drivers and passengers during a collision still needs to be explored. Therefore, in this study, an evaluation of body region injury due to AOP failure in frontal crash is conducted to validate and support NCAP rating. Analytic hierarchy process (AHP) is put forward on the basis of expert's input from various related fields to evaluate the injury to body regions and OFT protection during an accident based on the current situation. The results show that head, neck and chest indicated the highest severity, followed by knee, femur and lower leg with respect to the Consistency Ratio (CR) of 0.0633. This was in line with the focus of ASEAN NCAP's AOP protocol whereby the three body regions were deemed as the critical parts and required sufficient protection. Based on the findings, it is proven that ASEAN NCAP's consideration of OFT in AOP is well developed and suits the current needs.

“…As a result, numerous proposals have been made (e.g. Edwards et al 2012;Johannsen et al 2013;Johannsen and Thomson 2016). However, C2C collisions, which are the main focus of compatibility, are a complicated phenomenon because the combinations of vehicle models and collision conditions are quite diverse.…”

Objective: In 2020, the world's first crash compatibility rating test will be introduced in the European mobile progressive deformable barrier (MPDB) test. In this research, the quantitative change in partner protection performance of large vehicles in car-to-car (C2C) impacts was studied if these large vehicles were designed in future based on MPDB tests addressing crash compatibility ratings. Methods: Representative vehicles of the European fleet were selected and a Computer Aided Engineering (CAE) parameter study was conducted. In particular, by changing an indicator of structural interaction performance (SD; i.e., the degree of uniformity of barrier deformation)/mass/stiffness of large vehicles systematically in a step-by-step approach, the compatibility evaluation results of large vehicles in MPDB and the occupant injury score of small vehicles in C2C impacts were compared. The CAE result was evaluated compared to that of C2C physical impact tests. Results: The CAE parameter study showed that in the C2C impact condition, the effects on occupant injury in a small vehicle due to changes in the large vehicle were as follows: (1) SD change: The effect was minor except for small overlap condition. (2) Mass and stiffness change: The effect was relatively major. On the other hand, compatibility evaluation in the MPDB showed a tendency to overestimate the effect of SD change in comparison with the above-mentioned C2C impact condition. In addition, physical impact tests showed that, based on SD evaluation, the large vehicle with a relatively inferior compatibility rating compared to those with superior compatibility ratings showed a contradicting trend of better compatibility performance in the C2C test. Conclusions: The currently proposed compatibility evaluation method of the MPDB test showed some tendency to overestimate the effect of SD change and resulted in quantitatively inconsistent outcomes regarding occupant injury in the partner car in C2C impact conditions.
