This paper details the injuries occurring in real world trip-over only rollover crashes, for seat belted and contained occupants, and assesses whether these injuries can be replicated using a Jordan Rollover System (JRS) crash test rig recently installed at Crashlab in Sydney. This research forms part of the Dynamic Rollover Occupant Protection (DROP) project funded by the Australian Research C...

A set of state-of-the-art FE vehicle, restraint system, dummy, and whole body human models was constructed and validated against several sets of quasi-static and dynamic rollover tests. HIII dummy responses during three selected trip-over scenarios were simulated using an FE vehicle model equipped with four different roof stiffness values. It was found that the high dummy head accelerations and...

Recent analyses have established that 4WD vehicles are aggressive in crashes, causing comparatively more harm than other passenger vehicles when in collision with other road users, and have a high risk of rollover crashes. To assess the safety of these vehicles more completely, this study produced two analyses of risk: firstly, estimates of crash risk and injury rates using NZ data; and, second...

A Time-To-Rollover (TTR) metric is proposed as the basis to assess rollover threat for an articulated heavy vehicle. The TTR metric accurately “counts-down” toward rollover regardless of vehicle speed and steering patterns, so that the level of rollover threat is accurately presented. There are two conflicting requirements in the implementation of TTR. On the one hand, a super-real-time model i...

1 Graduate Student 2 Associate Professor, corresponding author ABSTRACT A Time-To-Rollover (TTR) metric is proposed as the basis to assess rollover threat for an articulated vehicle. Ideally, a TTR metric will accurately “count-down” toward rollover regardless of vehicle speed and steering patterns, so that the level of rollover threat is accurately indicated. To implement TTR in real-time, the...

Vehicle rollover represents a significant percentage of single-vehicle accidents and accounts for over 9000 fatalities and over 200,000 non-fatal injuries each year. Previous research has yielded rollover stability control systems that are effective in on-road conditions.Accident statistics show, however, that over 90% of rollovers involve road departure, during which a vehicle may encounter sl...

There is a recent trend of building roundabouts on highspeed roads, often with the considerable presence of heavy vehicles. With the increased presence of trucks on roundabouts, the issue of overturning has become a concern. Although some geometric, vehicle, and loading factors have been connected to rollover, the safety performance of roundabouts built on high-speed roads is not well understoo...

Soldiers incurred injuries or even lost their lives due to rollovers while driving military vehicles. A recent report identified that the one cause of rollovers is the driver’s inability to assess rollover threats, such as a cliff, soft ground, water, or a culvert on the passenger side of the vehicle, due to the vehicle’s width. To reduce the number of rollover accidents, a road-edge detection ...

Vehicle driving safety is an important performance indicator for vehicles, and there still much room development in the active control of electric vehicles. Vehicles are susceptible to rollover when making sharp turns or overtaking at high speed. In order improve anti-rollover stability vehicles (EV), this study proposes a real-time motor strategy, mainly according acquisition vehicle attitude ...

This letter constitutes the interim report of the Transportation Research Board Committee for the Study of a Motor Vehicle Rollover Rating System. This committee was convened in response to a request from the Congress asking the U.S. Department of Transportation to fund a study by the National Academy of Sciences on motor vehicle rollover. The main objectives of this report are (1) to present t...
