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 …

Parallel design optimization of multi-trailer articulated heavy vehicles with active safety systems
Multi-trailer articulated heavy vehicles (MTAHVs) exhibit unstable motion modes at high speeds, including jack-knifing, trailer swing, and roll-over. These unstable motion modes may lead to fatal accidents. On the other hand, these vehicle combinations have poor maneuverability at low speeds. Of …

Coordinated control of active safety systems for multi-trailer articulated heavy vehicles
… the directional performance of multitrailer articulated heavy vehicles (MTAHVs), the model-based active safety systems, including the active trailer steering, trailer differential braking and the active roll control are developed. The active safety systems are integrated and coordinated for …

A wireless communication based active safety system for articulated heavy vehicles
… been developed to improve the safety of road vehicles. This dissertation presents a novel active trailer steering (ATS) system using wireless communication to exchange data among controllers and sensors allocated on the leading and trailing units of an articulated heavy vehicle (AHV). …

Enhancing roll stability and directional performance of articulated heavy vehicles based on anti-roll control and design optimization.
… 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 regulator (LQR) controller is …

Design synthesis of articulated heavy vehicles with active trailer steering systems
A new design synthesis method for articulated heavy vehicles (AHVs) with an active trailer steering (ATS) system is examined and evaluated. Due to their heavy weights, large sizes, and complex configurations, AHVs have poor maneuverability at low speeds, and low lateral stability at high speeds. …

High-Speed Roll Stability Evaluation of A-Double Tractor-Trailers
The effect of center of gravity (CG) height and lateral 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 …
