THE AEB SYSTEM WITH ACTIVE AND PASSIVE SAFETY INTEGRATION FOR REDUCING OCCUPANTS' INJURIES IN HIGH-VELOCITY REGION

摘要

AEB (Autonomous Emergency Braking) is a representative safety system that assists a driver to avoid forward collision or mitigate crash velocity resulting in reduction of occupant's injury risk using ADAS sensor. This paper focuses on establishing appropriate PSB activation time in order to minimize occupant forward movement and head & neck injuries in the event of collision when it is unavoidable in the aspect of active and passive safety system integration. And also, it is the other goal that decreases the collision velocity by applying more efficient pre-braking profile. For this, AEB test is performed with H-3 5% & 50% human dummy seated in the passenger side. The test vehicle is equipped with Lidar and camera sensor fusion AEB system, PSB (Pre-Safety seatBelt) and a premium ESC module. From this study, the last time to activate PSB considering occupant's injury and the improved pre-brake profile beneficial to collision velocity reduction and occupant's behavior were verified.
