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 study, an anticipatory postural response...

Recent research revealed that greater proportion of heavier male occupants and lighter female occupants sustain serious injuries in frontal crash. The cause is thought that the frontal occupant restraint systems are designed to minimize the injury risk for 50 h percentile occupant only, and its characteristics are not adjustable. In this study, vent hole area of the airbag and load limiter forc...

OBJECTIVE Non-fatal tibia and ankle injuries without proper protection from the restraint system has gotten wide attention from researchers. This study aimed to investigate occupant tibia and ankle injuries under realistic frontal impact environment that is rarely considered in previous experimental and simulant studies. METHODS An integrated occupant-vehicle model was established by coupling...

Objective: To compare results from high probability matched sets versus imputed matched sets across differing levels of linkage information. Methods: A series of linkages with varying amounts of available information were performed on two simulated datasets derived from multiyear motor vehicle crash (MVC) and hospital databases, where true matches were known. Distributions of high probability a...

Rollover is not the most common type of accident, but the consequences may be serious. Understanding of the injury mechanisms during the complex rollover movement is limited and requires further investigation. ln-depth investigations of 21 Volvo cars involved in rollover crashes were analysed with regards to cause and outcome. Detailed information was examined about the crash scenario, the road...

The two primary functions of a vehicle climate control system are safety through de-icing and de-fogging windows, and occupant thermal comfort. However, vehicle air-conditioning systems can significantly impact fuel economy and tailpipe emissions of conventional and hybrid electric vehicles (HEVs) and reduce electric vehicle (EV) range. In order to meet the new U. S. Supplemental Federal Test P...

OBJECTIVE Public concern has arisen about the reliability of front air bags because Fatality Analysis Reporting System (FARS) data indicate many nondeployed air bags in fatal frontal crashes. However, the accuracy of air bag deployment, the variable in question, is uncertain. This study aimed to provide more certain estimates of nondeployment incidence in fatal frontal crashes. METHODS Fatall...

Injuries will inevitably occur when restraining loads are exerted on a car occupant by a seat belt during a crash. This study investigated the nature, frequency, and severity of such injuries to the chest and abdomen. Vehicle, occupant, and injury details were obtained from accidents occurring in the Midlands of England. The sample was chosen with emphasis on fatal and serious injuries while al...

The recent real-world experience with the frontal airbags and their sometimes unfortunate interaction with small size adults and children led to the analytical efforts and the results reported in this paper. The focus of this paper is an analytical study investigating the side impact protection performance of side airbags in interaction with, out-of-position occupants. The study evaluates inter...
