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...

Truck accidents involving rollover have extremely high fatality rates. About half of all truck drivers killed in accidents last year were involved in a rollover. Freightliner’s Rollover Stability Advisor alerts drivers to potential rollover situations, training them to avoid excessive rollover risk. In this paper, we describe work that extends the Rollover Stability Advisor to predict rollover ...

The safety of road vehicles depends on the yaw-roll dynamics. A loss of roll stability results in a rollover accident. Mechanisms to warn against rollover threat and a rollover avoidance control methodology are crucial in designing a successful active safety warning/control system for heavy-duty commercial vehicles. A dynamic rollover metric, Time-To-Rollover (TTR), has become popular in rollov...

The rollover evaluation index provides an important threshold basis for the anti-rollover control system of vehicle. Regarding risk independently driven heavy-duty vehicles, a new is proposed, and feasibility improved was verified through hierarchical HIL (hardware-in-the-loop) experiments. Based on 18-DOF spatial dynamics model vehicle, LTR (load transfer rate) obtained to describe dynamic cha...

BACKGROUND Rollover footwear is assumed to provide an enhanced surface over which the body can roll more easily. The aim of this study was to investigate the effects of rollover footwear on the rollover function of walking. METHODS Twenty subjects walked in three conditions: (i) a MBT shoe (Masai Barefoot Technology) characterized by a stiff sole rounded in the anterior-posterior direction; (...

In order to reduce the influence of unreasonable road alignment design on vehicle driving safety, a study optimization and safety based two-dimensional point collision dynamics was carried out. First, through model, relationship kinematic parameters before after deduced. Second, according vehicle–road coupling dynamic model analysis collision, threshold between radius circular curve superelevat...

An anti-rollover control algorithm based on the Time-To-Rollover (TTR) index is proposed in this paper. A simple model with steering and differential braking inputs was developed to calculate the TTR in real-time. The TruckSim dynamic simulation software is used to verify the final control performance, as well as simulating the dynamics in the driving simulator. Both the simple and complex (Tru...

This paper proposes a methodology that allows the combination of the Stability Factor and handling characteristic to predict the probability of rollover per single vehicle crash. Paper No.202-O Simulation of Occupant Kinematics in Vehicle Rollover Dummy Model versus Human Model Norbert Praxl, Markus Schönpflug, Jiri Adamec Institute for Legal Medicine Munich, Germany Abstract Currently, 25% of ...

Instability of vehicle can be defined as an unexpected response maneuver that induces disturbance, occurring in the ground plane. This include longitudinal, lateral, pitch, yaw, roll direction, or their combinations. Many tractor semitrailer accidents caused by lateral instabilities which may classified into two types: rollover and yaw instability. Rollover occurs when centrifugal forces impose...
