摘要/Abstract

摘要： 自动驾驶将乘员从驾驶任务中解放出来，乘员能选择更舒适的坐姿。研究了乘员在3种倾角坐姿下正面碰撞的运动响应与损伤,结果表明，大倾角坐姿下的乘员会发生下潜，增大损伤风险。针对这一现象，提出了座垫翻转的防护策略,该策略能大幅度降低乘员的损伤风险，座椅安全带约束下，120°坐姿乘员的肝脏应变降低至42.1％，150°坐姿乘员的心脏应变降低至24.3％。

关键词: 大倾角坐姿, 自动驾驶, 正面碰撞, 乘员损伤

Abstract: Autonomous driving liberates passengers from driving tasks, and allows them to choose more comfortable sitting postures. The motion responses and injuries of occupants in collisions were studied under three different sitting angles. The results show that the passengers will dive in a sitting position with a large inclination angle, resulting in an increased risk of injury. In response to this phenomenon, a protective strategy of seat cushion flipping was proposed. This strategy significantly reduces the injury risk of the occupants. Under the restraint of seat belts, the liver strain of occupants in 120° sitting position is reduced to 42.1%, and the heart strain of occupants in 150° sitting position is reduced to 24.3%.

Key words: high angle sitting position, automatic drive, front impact, passenger injury
