OBJECTIVE The aim of this study is to model occupant kinematics in an autonomous braking event by using a finite element (FE) human body model (HBM) with active muscles as a step toward HBMs that can be used for injury prediction in integrated precrash and crash simulations. METHODS Trunk and neck musculature was added to an existing FE HBM. Active muscle(More)
Cover: Finite element human body model equipped with feedback controlled muscles in a simulated maximum driver braking event, see Section 5.5. Image by Jonas Östh. Abstract Over 30 000 fatalities related to the road transport system are reported anually in Europe. Of these fatalities, the largest share is car occupants, even though significant improvements(More)
OBJECTIVE The aim of this study was to investigate the whole spine alignment in automotive seated postures for both genders and the effects of the spinal alignment patterns on cervical vertebral motion in rear impact using a human finite element (FE) model. METHODS Image data for 8 female and 7 male subjects in a seated posture acquired by an upright open(More)
Human body models (HBMs) for vehicle occupant simulations have recently been extended with active muscles and postural control strategies. Feedback control has been used to model occupant responses to autonomous braking interventions. However, driver postural responses during driver initiated braking differ greatly from autonomous braking. In the present(More)
The development of automotive safety systems is moving towards an integration of systems that are active before and during an impact. Consequently, there is a need to make a combined analysis of both the pre-crash and the in-crash phases, which leads to new requirements for Human Body Models (HBMs) that today are used for crash simulations. In the pre-crash(More)
