The vehicle’s lateral motion is one of the important factor to generate the dummy’s behavior during the IIHS small overlap crash event. In this respect, to accomplish sled tests successfully, it is necessary to simulate the vehicle’s longitudinal and transverse motion simultaneously. This paper describes a new test method on a small overlap sled test by simulating the vehicle’s dynamic lateral motion. The lateral motion was generated by using guide path which includes vehicle’s analysed lateral movement information, and linear motion guides and rails that could be allowed to move to lateral direction of vehicle’s body for sled test.

In a small overlap collision, the vehicle moves simultaneously in the longitudinal and transverse directions and sweeps the barrier or has rotational motion depending on the degree of deformation and support of the vehicle body. In particular, the rotational motion of the vehicle increases the lateral behavior of the occupant and can even cause occupant’s head to contact A pillar. Therefore, it is necessary to study restraint conditions to minimize the lateral behavior of occupant. In this study, we will define restraint conditions that affect behavior of occupant and introduce the results of sled test in the small overlap collision mode.
