Passenger Injury Analysis Considering Vehicle Crash after AEB Activation Authors: Seokhoon Ko, Garam Jeong, Dohyung Kim, Haekwon Park, Kyusang Lee, and Raeick Jang—Hyundai Mobis Abstract Owing to an increasing autonomous emergency braking (AEB) adoption, emergency braking before crash occurs more often than in the case of conventional vehicles. Due to the sudden deceleration in AEB activation, passengers move forward before the crash. To explore how this forward movement affects passenger injury, sled tests are performed with an inclined dummy…

An Experimental Confirmation of the Occupant Kinematic Response for Out of Position and Belt Tensioning Effect during Collision Avoidance System Authors: Myeongkwan Kang and Dohyung Lim—Mechanical Engineering at Sejong University in Korea; Hyung Joo Kim, Seonglae Kim, and Youngkuen Cho—Automotive Research & Development Division at Hyundai Motor Group in Korea Abstract The methodology of ensuring safety to occupants' is one of the major challenges about the Integral safety system. Many studies have focused on verification to securing occupants’ restraint during collision avoidance, but the out-of-position (OOP) parameter was not considered…

Machine Learning Based Model for Predicting Head Injury Criterion (HIC) Authors: Vikas Hasija—Bowhead (Systems & Technology); Erik G. Takhounts—National Highway Traffic Safety Administration (NHTSA) Abstract The objective of this study is to develop a machine learning based predictive model from the available crash test data and use it for predicting injury metrics. In this study, a model was developed for predicting the head injury criterion, HIC15, using pre-test features (vehicle, test, occupant and restraint related). This problem was solved as…

Investigating Combined Thoracic Loading Using the Elderly Female Dummy (EFD) Authors: Michael Beebe, Kris Sullenberger, Mark Burleigh, Joe McCarthy—Humanetics Innovative Solutions; John H Bolte IV—The Ohio State University Abstract The Elderly Female Dummy (EFD) is an omni-directional ATD developed to represent a vulnerable population. The EFD it is able to be 3D printed and quickly altered to meet design requirements. A recent side impact sled test series suggested that small, elderly females may be at risk of thoracic injuries in…

Novel use of a Halo Orthosis on Pediatric Anthropomorphic Test Devices (ATDs) in Frontal Sled Tests Authors: Julie A. Mansfield and John H. Bolte IV—Injury Biomechanics Research Center, The Ohio State University; Eric A. Sribnick—Department of Surgery, Division of Neurosurgery, Nationwide Children's Hospital/ Department of Neurosurgery, The Ohio State University College of Medicine; Carrie Rhodes—Passenger Safety Program, Nationwide Children's Hospital; Vera Fullaway—Research and Development, Safe Traffic System, Inc. Abstract Children recovering from cervical spine injuries may need a halo orthosis, which rarely fits into traditional child…

Pediatric Cervical Spine Strength and Stiffness in the Sagittal Plane Authors: Yadetsie N. Zaragoza-Rivera, John H. Bolte IV, and Laura C. Boucher—Injury Biomechanics Research Center, The Ohio State University Abstract In the pediatric safety field the use of computer simulations to assess passenger kinematics is becoming more prevalent. However, there is a need for volunteer data to serve as a baseline for biomechanical responses to better appraise the biofidelity of these simulations. The objective of this study is to provide…

Volume and Pressure Considerations in Human Body Modeling Authors: Jiri Kral and Anderson de Lima—General Motors Company Abstract The initial presence and dynamic formation of internal voids in human body models have been subjects of discussion within the human body modeling community. The relevant physics of the human body are described and the importance of capturing this physics for modeling of internal organ interactions is demonstrated. Basic modeling concepts are discussed along with a proposal of simulation setups…

Improvements in Simulations of Aortic Loading by Filling in Voids of the Global Human Body Model Authors: Anderson de Lima and Jiri Kral— General Motors Company Abstract Internal organ injuries of the chest are one of the leading causes of deaths in motor vehicle crashes. The issue of initial presence and dynamic formation of voids around the heart and aorta is addressed to improve kinematics, force interaction and injury risk assessment of these organs of the Global Human Body Model. Steps to fill the voids are…

The Effect of An Acoustic Startling Warning On Take-Over Reaction Time And Trunk Kinematics for Drivers in Autonomous Driving Scenarios Authors: Valentina Graci, Madeline Griffith, Jalaj Maheshwari, Rahul Akkem, Meta Austin, Thomas Seacrist, and Kristy B. Arbogast—Center for Injury Research and Prevention, Children’s Hospital of Philadelphia Abstract The Acoustic Startling Pre-stimulus (ASPS, i.e. a loud sound preceding a physical perturbation) was previously found to accelerate action execution in simple flexion exercises. Therefore in this study we examined if ASPS can accelerate take-over reaction times in restrained teen and adult drivers…
