However, according to the relevant data, the front collision is the main form of vehicle collision accidents, the highest fatality rate in the front collision accidents is the front small overlap offset collision accidents (the overlap rate of the vehicle body and the collided object during the collision is not more than 30%, and the front small overlap collision is short for short), the front small overlap collision fatality accidents account for about 22% of the total number of the front collision fatality accidents in the united states, about 27% of the total number of the front collision fatality accidents in the united kingdom, and the fatality rate is much higher than that of other types of vehicle front collision accidents. The above data indicate that the frontal small overlap crash is closer to a real traffic crash, which places higher demands on the safety performance of the vehicle. In 8 months 2012, statistical data of the american highway safety insurance association (IIHS) on traffic accidents in the united states shows that a front 25% overlap crash test procedure for dealing with small front overlap crashes of vehicles is firstly proposed in the new vehicle crash safety evaluation procedure (NCAP), and in the first 11 luxury vehicle types of test results published by the association, the evaluation excellence rate is only 18%, which indicates that most vehicles do not have good capability of dealing with the type of crash accidents at present.
According to the traditional design, in IIHS 25% offset collision, a vehicle body longitudinal beam and a barrier are staggered, so that the collision deformation energy absorption effect cannot be achieved, energy is absorbed only through few structural components such as a front upper longitudinal beam, a side wall and the like, and the vehicle body has huge intrusion amount and acceleration peak value; in addition, since the vehicle body rotates about the vertical axis, the dummy head may be displaced from the airbag center to hit the left side of the steering wheel or the a-pillar area, thereby causing further injury.
