Low-Speed Maneuverability, High-Speed Roll-Stability, and Brake Type Performance of Heavy Truck 33-ft Double Trailers
… detailed herein highlight 33-ft double trailers' off-tracking, roll-stability with stability control systems, and brake type influence on braking performance. The first study compares low-speed off-tracking of a 33-ft double to 28-ft double and 53-ft single configurations via simulation and …

Vision-based trailer pose estimation for articulated vehicles
… vision-based articulation angle and trailer off-tracking sensing for HGVs. Chapter 1 provides a background and literature review, covering important vehicle technologies, existing commercial and experimental sensors for articulation angle and off-tracking measurement, and relevant …

Kinematic Analysis Of A Two Body Articulated Robotic Vehicle
… bodies. The new linkage design minimizes vehicle off-tracking by allowing the rear wheels to closely track the path of the front wheels. This thesis will outline the theoretical kinematic model of the four-bar linkage as applied to a twin-bodied, differentially driven vehicle. The kinematic model …

Autonomous driving control strategies for multi-trailer articulated heavy vehicles with active safety system
… curved path negotiations, the path-following off-tracking performance is emphasized, and the low-speed path-following mode is activated. It also takes benefits of the vehicle units’ body-fixed reference frames for lateral deviation calculations to mimic the driver’s local perception of vehicle …

Torque Actuated Rear Steering for Urban Electric Commercial Vehicles
… (LQR) to enhance roll stability and reduce off-tracking. Results showed that the rear steering could provide significant improvements to both. In chapter 6, the use of rear steering in braking scenarios is investigated by using adaptive Model Predictive Control (MPC) to manage the …

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. …
