Dynamic Modeling and Lateral Stability Analysis of Long Combination Vehicles
… modeling evaluation of the dynamic stability of Long Combination Vehicles (LCVs) that are commonly operated on U.S. highways, using multibody dynamic simulations in MATLAB/Simulink®. The dynamic equations for a tractor with two trailers connected by an A-frame converter dolly (A-Dolly) are …

A Safety Analysis of Left-Turning Maneuvers for Long-Combination Vehicles
… number of goods are shipped in Ontario using long-combination vehicles (LCVs). LCVs can significantly increase the amount of cargo carried per shipment, while reducing shipping costs and environmental impacts of freight road travel. Questions remain regarding their safety due to their larger …

Directional analysis of an a-train double with damped articulation
… in weights and dimensional policies on freight vehicles, the population of heavier and longer articulated vehicles, often referred to as Long Combination Vehicles (LCVs), has steadily increased in North America. The directional stability and control limits of most combinations have been …

Low-Speed Maneuverability, High-Speed Roll-Stability, and Brake Type Performance of Heavy Truck 33-ft Double Trailers
… due to current federal restrictions limiting long-combination vehicles to 28-ft doubles. With the continual rise in e-commerce, however, there is a push by package carriers on legislation to permit carriers to introduce 33-ft doubles into their fleets. Three separate studies detailed herein …

Design and validation of high speed active trailer steering system for articulated heavy vehicle
Articulated heavy duty vehicles are widely used around the world for its economic and environmental benefits. A-train double is one of the most popular heavy duty vehicles in Canada. Despite its advantages, the spread of A-train is hampered by poor lateral dynamic performance and poor accident …

High-speed lateral stability analysis of articulated heavy vehicles using driver-in-the-loop real time simulation
… stability of multi-trailer articulated heavy vehicles (MTAHV) include the use of both an open-loop and a closed-loop maneuvers as specified in ISO-14791. The standard testing procedures are used to determine the Rearward Amplification (RA), which is a well-accepted performance measure for the …

SPACE-CONSTRAINED AUTONOMOUS REVERSING OF ARTICULATED VEHICLES
… control methods for autonomous reversing of long combination vehicles (LCVs). These approaches not only significantly improve the performance of previous autonomous reversing systems, but also address a major gap in the reversing control literature for LCVs. The methods were validated by …

Vision-based trailer pose estimation for articulated vehicles
Articulated Heavy Goods Vehicles (HGVs) are more efficient than conventional rigid lorries, but exhibit reduced low-speed manoeuvrability and high-speed stability. Technologies such as autonomous reversing and path-following trailer steering can mitigate this, but practical limitations of the …
