Research on Avoidance Operations in Emergency Situations

- In Case of Large Overlap Rate-

Abstract

With the social demand to reduce traffic accidents, understanding of driving behavior in traffic accident is important for not only developing automobiles but also for discussion on the standardization of ADAS(Advanced Driver-Assistance Systems). In this study, we conducted an experiment using driving simulator, and investigated the differences in driving behavior by age group (elderly, middle-aged, and young) when they were avoiding unexpected collisions. As a result, it was found that many drivers avoid collision by steering in high speed situation, and the avoidance direction is on the driver’s side. ESF (Emergency Steering Function) operation timing that less interfere with driver's steering maneuver has also been proposed.
