To be published on 2019-11-21 by SAE International in United States
M. Priyanka, Mahindra & Mahindra, India Sai Himaja Nadimpalli , Mahindra & Mahindra, India Keywords-Safety, Connectivity, GPS Research and/or Engineering Questions/Objective: There are many times the driver or co-passenger can experience emergency conditions whenever the vehicle is running or it is in static. These kind of situations are tough to handle even if one is victimized . The victim can be rescued on time if proper information about the situation would reach his friends or family . Limitations: In existing system, if the accidental crash happens then signal from airbag unit will wake up the mobile, Once this wake up call happens,it will activate the gsm module. The emergency contacts stored in the mobile will be dialed up and the victim can convey his emergency situation through that. The driver will be rescued only if crash happens. There is no system to rescue the driver if heart attack happens when he is driving. The additional problem which the system has is emergency contact is out of town,the victim will not be rescued Methodology: In order…

To be published on 2019-11-21 by SAE International in United States
Several people die every year due to vehicle accidents. Federal Motor Vehicle Safety Standards (FMVSS) are U.S. federal regulations stating design, structure, performance, and durability necessities for vehicles. The objective of a crash test for FMVSS No. 208 is to measure how well a passenger vehicle would protect its occupants in the event of a frontal crash. FMVSS 208 consists of series of tests including different impact surface type as well as occupant sizes. It also covers the belted and unbelted occupant behavior at the time of front impact. Each test scenario has different ways to injure the occupant. Airbags are the part of passive safety equipment family in any automobile and play an imperative role to reduce the occupant head and chest injuries at the time of crash or accidents. This study covers the evaluation of airbag performance in all FMVSS 208 load cases using validated Finite Element Methodology (FEM). Finite Element Analysis (FAE) is an advanced tool to simulate the airbag behavior. Airbag deployment phenomena is very complex in nature and depend on…

Injury Reduction in Vehicle to Pedestrian Collision using Deployable Pedestrian Protection System in Vehicles

International Centre for Automotive Technology-Jitendra Singh Gaur
  • Technical Paper
  • 2019-28-2551
To be published on 2019-11-21 by SAE International in United States
Head injuries are the main source of road fatalities in when a pedestrian is involved in an accident with the vehicle. The frontal part of vehicle such as engine hood, lower-windshield area and A-pillars are the possible location of head impact in such accidents. The head impact with hard points located in these areas result in the fatal head injuries. The effect of impact can be reduced by using the deployable pedestrian protection systems (DPPS) such as hood-lifters and windshield airbag in the vehicle. The study shows how these systems are effective in reducing the fatalities in pedestrian accidents and how to evaluate the performance of these deployable systems.

“EFFECT OF DRIVER AIRBAG VENT HOLE SIZES IN THE PERFORMANCE OF THE AIRBAG AND FORCES OCCURRING ON THE DRIVER BODY DUE TO THE AIRBAG DEPLOYMENT IN CASE OF ACCIDENT”

International Centre for Automotive Technology-Harpreet Singh Juneja
  • Technical Paper
  • 2019-28-2416
To be published on 2019-11-21 by SAE International in United States
Airbags are very important passive safety component used in vehicle for the safety of the driver during the accident. Airbags are provided with the vent hole for the immediate discharge of the gases which fills the airbag during deployment in case of any accident. Size of the airbag vent hole plays a very important role for the performance of airbag in reducing the driver Injury. Study shows the difference in the performance of the airbags in terms of driver injury and airbag displacement with change in the size of the vent hole for the same airbag.

The Effects of Front-Mounted Accessories on Air Bag Sensors and Crashworthiness

Motor Vehicle Council
  • Ground Vehicle Standard
  • J2431_201910
  • Current
Published 2019-10-09 by SAE International in United States

Almost all light trucks now are being manufactured with at least a driver side air bag and all will have dual air bags by 1998. The driving forces behind this feature are occupant safety, federal regulations, and competition in thie industry. Along with the booming popularity of pickups and SUVs, they are commonly accessorized with a wide variety of products. Many acessories for four-wheel drives in particular are mounted on the front of the vehicle. These products include grille/brush guards, winches, snow plows, replacement bumpers, bicycle carriers, etc. Concerns have arisen over the compatibility of these accessories with the vehicle's air bag system.

Honda ready with new injury-reducing airbag

Automotive Engineering: October 2019

Published 2019-10-01 by SAE International in United States

Starting next year, Honda will begin fitting vehicles with a new, advanced-design passenger-side front airbag that its engineers said is designed to mitigate brain and neck injuries by cradling the head like a baseball in a catcher's mitt. The design is particularly effective, Honda said, for angled impacts or when an occupant is not in optimal position when the crash occurs, reducing rotational acceleration of the head that can traumatize the brain.

Incompressibility of the brain makes it susceptible to damage from shear strains. Head rotational motion can easily produce high shear strains causing brain injury. Since head injury criterion (HIC) does not account for rotational motion, a brain injury criterion (BrIC) was developed. To design potential countermeasures for reducing BrIC, it is important to investigate the parameters that influence BrIC. This article focuses on parametric analysis to examine the sensitivity of BrIC to vehicle design and crash-related parameters, and identifying important parameters which can be controlled in developing countermeasures for reducing BrIC. Global Human Body Models Consortium (GHBMC) 50th percentile male simplified human finite element (FE) model was used in this study. Four different analyses were conducted: a Design of Experiments (DOE) study to investigate sensitivity of BrIC to impact direction and crash pulse severity b DOE studies, with fixed crash severity, for frontal, far side oblique, and near side oblique crash modes to identify important vehicle design parameters influencing BrIC c Optimization for frontal, far side oblique, and near side oblique crash modes to minimize…

Innovative Knee Airbag (KAB) Concept for Small Overlap and Oblique Frontal Impacts

Detroit Engineered Products (DEP) Inc.-Rahul Makwana
Ford Motor Co., Ltd.-Pardeep Jindal
Published 2019-04-02 by SAE International in United States
Considerable research has been conducted in terms of attempting to reduce lower leg injury risk in full frontal impacts, in some cases by the use of a knee airbag (KAB). However, there has been limited research into the performance of KAB systems during a crash test with increased oblique loading, such as the IIHS small overlap frontal test, an oblique moving deformable barrier test (OI) being researched by NHTSA, and a mobile progressive deformable barrier test (MPDB) that is expected to be implemented by Euro NCAP in the next few years. The objective of the current numerical study was concentrated on the evaluation of an innovative KAB concept design intended to reduce ATD right inboard lower leg/foot responses under small overlap and oblique loading conditions. A novel appendage KAB concept design was developed with the help of morphing and computational studies which were performed with different ATD sizes. In the study, one of the lower leg/foot responses was monitored and compared over a conventional KAB design. Cases investigated in the study showed that the novel…
