Digital human modeling (DHM), as a convenient and cost-effective tool, is increasingly incorporated into product and workplace design. In product design, it is predominantly used for the development of driver-vehicle systems. Most digital human modeling software tools, such as JACK, RAMSIS and DELMIA HUMANBUILDER provide functions to predict posture and positions for drivers with selected anthr...

In recent years, the development of airbag system has improved the safety of the occupants. However, the car occupant can be often killed by improper airbag operation. Robust detection of vehicle occupant posture is necessary for a safer intelligent airbag deployment system. This paper presents a stereobased method of estimating the posture of the occupant. Utilizing the disparity images and th...

This research compares the ability of delta-V and the occupant impact velocity (OIV), a competing measure of crash severity, to predict occupant injury in real world collisions. A majority of the analysis is performed using 191 cases with vehicle kinematics data from Event Data Recorders (EDRs) matched with detailed occupant injury information. Cumulative probability of injury risk curves are g...

objectives: one of the applications of ergonomics disciplinary is designing driver workstation compatible to users’ characteristics. the aim of this study was evaluation of interior design of shoka vehicle with respect to the accommodation for iranian population and proposing suggestions for customizing design of the vehicle. methods: this study was a descriptive-analytical study conducted amon...

vehicle occupants comprise a considerable proportion of traffic crash victims in iran. this paper has focused on vehicleoccupants’ injury severity and employed the classification and regression tree (cart) technique in order toidentify the most important variables affecting the injury severity of these road users in crashes occurred on rural freewaysand multilane highways in iran over a three y...

Wheelchairs are primarily designed for mobility and are not necessarily intended for use as motor vehicle seats. However, many wheelchairs serve as vehicle seats for individuals unable to transfer to a vehicle seat. Subjecting wheelchairs to sled testing, in part establishes the crashworthiness of wheelchairs used as motor vehicle seats. Computer simulations provide a supplemental approach for ...

OBJECTIVE Rollover crashes account for more than 33% of all motor vehicle-related fatalities and have the highest fatality risk of all crash types, at 1.37% in the United States. There is increased awareness of the high fatality rate associated with this crash type, but there is very limited pediatric-specific data related to rollover crashes in the United States. Recent focus on rollover mitig...

Two series of finite element and lumped parameter model vehicle-to-vehicle frontal crash simulations were conducted. The vehicles modeled are the 1994 Chevrolet C-1500 light truck and the 1997 Ford Crown Victoria. The first set of simulations involves fully-engaged angled impact. Angles range from +50° to -50°. The second set simulates offset impacts in head-on vehicle crashes. The front-end ov...

Side impact crash is a leading cause of fatalities on the roadways of the industrialized world. In the mid 1990's NHTSA implemented a new car assessment program testing the lateral crashworthiness of vehicles entering the market with a moving deformable barrier. Previous work has been done in an attempt to distill these tests into finite element simulations using specific vehicle test results; ...

Analysis of the vehicle occupant posture is a key problem in designing “smart airbag” systems. Vision based technology could enable the use of precise information about the occupant’s size, position, and posture in making airbag deployment decisions. In this paper, we present our experiments in estimation of the body posture of a sitting person using a motion capture system that performs analys...
