Influence Evaluation of Error Factors on Occupant Behavior in Pre-crash by using Experimental Design

Abstract

We evaluate influence of error factors on occupant posture behavior in pre-crash by experimental design method. By using a sled model for car crash analysis with a seat and a virtual human model considering a muscle tone, effects of error factors such as seat position, seatback angle, and vehicle behavior on occupant posture changes are analyzed. In addition, we investigate influence of error factors on injury risk of occupant posture by frontal impact analysis.
