Experimental Evaluation of Roll Stability Control System Effectiveness for A-double Commercial Trucks
… (CVeSS) at Virginia Tech for evaluating the roll stability of commercial trucks with 33-ft A-double trailers are evaluated. The study includes straight-rail trailers with heavy and light loading conditions. Commercial trucks are more susceptible to rollovers than passenger cars because of …

Experimental Evaluation of the Dynamic Performance Benefits of Roll Stability Control Systems on A-train Doubles
The ride stability of an A-train 28-foot double tractor trailer when outfitted with different Roll Stability Control (RSC) systems with the same payload and suspension configurations is studied experimentally for various dynamic maneuvers. The primary goal of the study is to determine the effect of …

Analysis, detection and early warning control of dynamic rollover of heavy freight vehicles
The conceptual design of the early warning based roll instability enhancement system is realized through systematic investigations on static and dynamic roll behavior of the vehicles, identification of indicators for the onset of instability, and reliability analysis. The relative and absolute roll …

A New Fuzzy Based Stability Index Using Predictive Vehicle Modeling and GPS Data
… Additionally, the increasing use of yaw and roll stability control in commercial trucks has contributed to an increased level of safety for truck drivers. However, these systems require the vehicle to begin a yaw or roll event before they assist in maintaining control. This thesis presents a …

High-Speed Roll Stability Evaluation of A-Double Tractor-Trailers
… and longitudinal off-centering on high-speed roll stability of A-double tractor trailers with 28-ft and 33-ft straight-rail and drop-frame trailers is evaluated through simulation and track testing. The changes in CG position due to the type of trailer (straight-rail vs. drop-frame) and …

Roll and Yaw Stability Evaluation of Class 8 Trucks with Single and Dual Trailers in Low- and High-speed Driving Conditions
A comprehensive evaluation of roll and yaw stability of tractor/semitrailers with single and dual trailers in city and highway conditions is conducted. Commercial vehicles fundamentally behave differently in city driving conditions than at high speeds during highway driving conditions. In order to …

Enhancing roll stability and directional performance of articulated heavy vehicles based on anti-roll control and design optimization.
… an investigation to actively improve the rollover stability of articulated heavy vehicles (AHVs) during high speed manoeuvres using anti-roll control systems. A 3-dimensional (3-D) linear yaw/roll model with 5 degrees of freedom is developed. Based on this model a linear quadratic …

Low-Speed Maneuverability, High-Speed Roll-Stability, and Brake Type Performance of Heavy Truck 33-ft Double Trailers
… (CVeSS) at Virginia Tech on the maneuverability, roll-stability, and brake type performance of 33-ft double trailers. Little literature exists for 33-ft doubles because they are uncommon on the U.S. roads due to current federal restrictions limiting long-combination vehicles to 28-ft doubles. With …

Development of a Heavy Truck Vehicle Dynamics Model using Trucksim and Model Based Design of ABS and ESC Controllers in Simulink
… and a model-based design of ABS and ESC controllers. In addition to this, a Hardware-in-the-Loop (HIL) simulation of an Anti-lock Braking System (ABS) for a heavy truck was performed using dSPACE. TruckSim, developed by Mechanical Simulation Corporation (MSC), was used to model the …

Hardware in the Loop Simulation of a Heavy Truck Braking System and Vehicle Control System Design
… transmitted and received with the electronic control unit utilized by the ABS system. For the software in the loop simulation (SIL), anti-lock braking (ABS) and roll stability control (RSC) algorithms were developed using Simulink and tested with the TruckSim model. By properly simulating the …
