Honda has a long history of studying Car-to-Car frontal collisions as a part of our real world crash safety research. This research led to the original Advanced Compatibility Engineering (ACE) frame, first introduced at ESV 2003. ACE was developed for the purpose of improving compatibility performance and has been widely applied to Honda’s mass production vehicles. Since Honda’s original Car-to-Car testing, the Moving Progressive Deformable Barrier (MPDB) test has been examined as a possible test to represent the behavior of Car-to-Car frontal collisions. However, the research about the similarity of MPDB test to an actual Car-to-Car crash mode is quite limited. The objective of this study is to evaluate MPDB test method by comparing results from MPDB tests to actual Car-to-Car crash tests. These results are used to propose improvements in MPDB test condition for improving the ability of the MPDB to reproduce an actual Car-to-Car crash.
