主动翻转座垫对倾斜坐姿乘员的保护
Protective measures of active flipping cushions for occupants in inclined seating positions
摘要
Abstract
The active flipping cushion protection strategy was proposed to improve the collision safety in autonomous vehicles.The flipping cushion actively to different angles before collision was used to reduce the occupant injuries.The proposed strategy was verified through simulation experiments,and the collision model was validated using cadaver test data.The active cushion flipping model was adjusted,and the simulations were conducted with the THUMS human body model for 100％frontal collision to determine the cushion flipping angle with the minimum overall injury risk in 300 ms timeframe.The results show that the active flipping cushion measure effectively reduces occupant injury risk in frontal collisions.Specifically,when the cushion is flipped to 35°,the occupant's overall injury risk is minimized.Without the flipping measure,the occupants experience submarining due to the inclined seating posture,which increases the risk of injury to internal organs and head.With the active flipping cushion measure,the submarining is effectively suppressed,which reduces the risk of internal organ injuries,but it can increase the risk of lumbar injury.The active flipping cushion measure unavoidably causes the compression in the chest region.However,compared to the scenario without the measure,the risk of chest injuries is significantly reduced.关键词
