in this paper, a method based on binary-coded genetic algorithm is proposed to explore an optimization method, for obtaining an optimal elliptical tank. this optimization method enhances the rollover threshold of a tank vehicle, especially under partial filling conditions. minimizing the overturning moment imposed on the vehicle due to c.g. height of the liquid load, lateral acceleration and ca...

With the features of high centroid, high load capacity and high aspect ratio, heavy vehicles are prone to rollover when running at high speeds in the corners, so the study of heavy vehicle rollover warning method presents important realistic meanings. In this paper, firstly, the composition of early warning systems is analyzed, and then the principles of rollover warning method based on suspens...

The rollover accidents in the tractor semi-trailer are often fatal and many factors could cause the tractor semitrailer rollover. In this paper, a rollover prevention control method was proposed based on real-time calculation of rollover index. The vehicle Center of Gravity CG height from the ground is an important parameter in the rollover index and it is estimated through lateral acceleration...

Transport Canada’s Dangerous Goods Directorate (TDG) data base of crashes involving a vehicle carrying dangerous goods shows 810 rollovers in 1,874 reported crashes from 1990 to 1998, and 83% of these involved highway tank trucks. TDG is therefore considering approaches to improve the rollover stability of tank trucks used for highway transportation of dangerous goods. TDG asked the Centre for ...

Articulated liquid cargo vehicles transporting inflammable fuels and dangerous chemical products require special consideration when traveling on urban roads or cruising at highway speeds. The road safety and handling of these kinds of vehicles may be adversely affected when negotiating sharp turns or travelling on slippery roads, which may result in either lateral instabilities or complete roll...

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 ...

An anti-rollover control algorithm based on the Time-To-Rollover (TTR) metric is proposed in this paper. A simple model with steering and direct yaw moment control inputs was constructed to calculate the TTR in real-time. The TruckSim dynamic simulation software was used to verify the control performance, as well as to simulate the system dynamics in the UM-Oakland driving simulator. Both the s...

In this paper we present an adaptive controller implementation based on the multiple models, switching, and tuning (MMST) paradigm [13, 14, 15] for preventing un–tripped rollover in automotive vehicles. Our approach relies on differential-braking to keep the value of the Load Transfer Ratio (LT R) below a threshold. We first employ multiple models to infer the unknown center of gravity height a...
