A study of the effect of reclined seatback on the occupant kinematics in an autonomous emergency braking using a MADYMO active human body model

摘要

In the future car, the highly autonomous driving system will have the leading-role for controlling. The driver will release the car's control intervention and tend to find a more comfortable seated posture. It is predicted that highly reclined seatback posture would have a potentially higher rate in comparison with some other seated positions, especially in the long-range travel with the highly autonomous driving. The highly reclined seatback with the standard D-ring on B-pillar belt left along welt around the occupant's rib cage needs to be investigated the efficiency because it was concluded that the belts only work well when they're worn correctly. Also, earlier research has shown that a lack of awareness could significantly increase the response time of the driver and longer reaction time in pre-crash in autonomous driving. This work aims to evaluate the impact of the reclined rear seatback on the occupant kinematics in the autonomous emergency braking (AEB) maneuver. A computational method that used the MADYMO human body model to simulate the behavior of the occupant in various different reclined seatback angles during the AEB with a standard D-ring seatbelt system (D-ring on the B-pillar) and seat-integrated D-ring belt system (D-ring on the seat structure), and various muscle tension levels.
