SPACE-CONSTRAINED AUTONOMOUS REVERSING OF ARTICULATED VEHICLES
… 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 implementing them at …

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 …

Design optimization of articulated vehicles with autonomous steering control
… collisions. To increase the safety of road vehicles, extensive studies have been conducted on developing autonomous driving technologies. However, little attention has been paid to exploring autonomous articulated vehicles (AVs). This thesis proposes an approach to the design synthesis of …

Robust controller design for active trailer steering systems of articulated vehicles using multi-objective optimization
… steering (ATS) systems to increase the safety of articulated vehicles. By applying a multi-objective evolutionary algorithm (MOEA) to the design optimization of the robust ATS controller, a series of optimal gain values can be obtained in a single run. This allows for posteriori decision making …

Fractional Order State Feedback Control for Improved Lateral Stability of Semi-Autonomous Commercial Heavy Vehicles
… and semi-autonomous large commercial heavy vehicles, the lateral stability control of articulated vehicles have caught the attention of researchers recently. Active vehicle front steering (AFS) can enhance the handling performance and stability of articulated vehicles for an emergency …

Development of active trailer steering systems for pickup truck-trailer combinations
Lateral dynamics of articulated vehicles continue to remain a subject of concern in the design of safety systems. Vehicle-trailer combinations tend to exhibit low lateral stability and poor maneuverability, especially under high-speed maneuvers, which lead to unstable motion modes such as …

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 …

Analysis, detection and early warning control of dynamic rollover of heavy freight vehicles
… 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 instability criteria are initially derived from the rollover mechanics of different heavy vehicle combinations. The …

Modelling and control of an articulated underground mining vehicle
… Both kinematic and dynamic modelling of LHD vehicles are introduced. Various forms of kinematic models are given and their underlying modelling assumptions are named. The most prominent assumptions concern the vehicle’s half-length and the inclusion of a wheel-slip factor. Dynamic modelling …

Brake-Actuated Steering of Heavy Goods Vehicles
Large-scale adoption of higher capacity vehicles in road freight transport can significantly improve transport productivity and reduce fuel consumption and greenhouse gas emissions. To date, their adoption in the UK is limited by their reduced low-speed manoeuvrability. Active rear-steering …
