Special Issue Information

Dear Colleagues,

In the rapidly evolving world of autonomous vehicles (AVs), the importance of effective mission planning cannot be overstated. As the "brain" of an AV, mission planning involves considering numerous critical factors that impact the success of AV operations. These factors include mission objectives, global and local planning, vehicle capabilities and limitations, environmental conditions and disturbances, the risks associated with maneuvers, collision avoidance, and motion regulations. By addressing these factors, advanced AV mission planning algorithms can ensure the optimized operation of autonomous vehicles in various scenarios. Therefore, the success of AV technology highly depends on the development and implementation of elaborate mission planning systems. This Special Issue aims to promote novel mission planning algorithms with a significant interest in collision avoidance.

Topics of interest include but are not limited to:

  • Mission planning in autonomous (aerospace, marine and ground) vehicles.
  • Rules-based collision avoidance algorithms based on: the Traffic Alert and Collision Avoidance System (TCAS), COLREGS—International Regulations for Preventing Collisions at Sea, ISO SOTIF, and so forth.
  • Modern online collision risk assessment approaches.
  • Novel collision avoidance techniques and their implementations.
  • Machine learning and other advanced algorithms for mission planning and collision avoidance.
  • Implementation and test results.

This paper presents a range control approach for implementing hard geofencing for unmanned air vehicles (UAVs), and especially remotely piloted versions (RPVs), via a proposed anticipatory range calculator. The approach employs turning circle intersection tests that anticipate the fence perimeter on approach. This ensures the vehicle turns before penetrating the geofence and remains inside the allowable operational airspace by accounting for the vehicles’ turning dynamics. Allowance is made for general geozone shapes and locations, including those located at the problematic poles and meridians where nonlinear angle mapping is dealt with, concave geozones, narrow corners with acute internal angles, and transient turn dynamics. The algorithm is shown to prevent any excursions using a high-fidelity simulation of a small remotely piloted vehicle. The algorithm relies on a single tuning parameter which can be determined from the closed-loop rise time in the aircraft’s roll command tracking. Full article

Abstract

Advanced driving algorithms, control strategies, and their optimization in self-driving vehicles in various scenarios are hotspots in current research; 4WS-4WD (four-wheel steering and four-wheel drive) is another hotspot in the study of new concept models; and the nonlinear dynamic characteristics of self-driving vehicles (AVs) are prominent in the fast cornering mode, which leads to a significant reduction in the accuracy and stability of trajectory tracking. Based on these research backgrounds, this paper proposes a control strategy optimization idea based on the 4WS4WD vehicle and its optimization model. The main content includes the establishment of a 3D vehicle model that takes into account vehicle load transfer and position change, and the establishment of a hierarchical control strategy based on the optimized NMPC and 4WS4WD models. The controller consists of two parts: an upper tracking controller based on the new vehicle model and NMPC, and a lower decoupled controller. The tracking control effect of the algorithmic control strategy based on the model and controller is validated in the high-speed serpentine motion mode and double-shift linear motion mode on the joint simulation platform of Car Sim and Simulink.
