Abstract
It is necessary to improve the occupants' safety in crashes between different type vehicles(e.g., between SUVs and sedan-type vehicles). Formerly, authros analyzed the frontal collision between same weight SUV and sedan, by the statistical traffic accident data stored in ITARDA (Institute for Traffic Accident Research and Data Analysis), and confirmed that, regardless of same weight, the rate of fatal or severe injuries of SUV drivers in lower than that of sedans. So, in this paper, authors tried the analysis for other weight combination (e.g., light SUV to heavy sedan collision or heavy SUV to light sedan collision, ets.), to see the general tendency of SUV to sedan collision. From the tendency of drivers' injuty, in this analysis, we presumed that upper part of sedan cabins are crushed by front-end of SUVs depended of the vertical offset configuration between SUVs and sedan-type vehicles.
