Special Issue Information

Dear Colleagues,

The purpose of research and development of functions and components of connected and automated vehicles is to enhance various aspects of mobility. The most important tasks are to guarantee efficient, comfortable, safe, and economical transport by exploiting signals from sensors and communications. Since recent developments and commercialized products are at still relatively low levels concerning SAE automation requirements, there is a wide range of further research and development possibilities. At the same time, technical and technological tools, methods, and solutions are improving continuously and providing greater possibilities for development.

The development of connected and autonomous driving can be classified into various disciplines. In environment perception and situation evaluation communication technologies, sensor fusion, mapping, and localization and evaluation methods provide data for the decision-maker layer. At this layer, interconnection provides additional signals. Based on the monitored situation, decisions must be made about vehicle maneuvers, such as route planning, trajectory design, speed selection, obstacle avoidance, overtaking, etc. The most important evaluation methods include Bayesian inference, game theory, optimization approaches, and areas of machine learning and deep learning.

Cooperative control of autonomous vehicles is aimed at guaranteeing a large number of performance requirements in traffic. Recently, a great deal of emphasis has been placed on state-of-the-art control design methods based on machine learning tasks and efficient optimization procedures. The purpose is to combine classical control design methods and various learning structures in order to provide less complex and computationally-intensive solutions. Guaranteeing stability and performances for complex management architectures is also a considerable challenge. These architectures require the development of new types of testing and validation procedures, as well as prototype constructs for testing purposes. Moreover, alternative procedures such as simulations, HIL/SIL tests, and virtual reality are also in the focus of research.

Potential topics include but are not limited to the following:

  • Environment perception and situation evaluation;
  • On-board sensor signals, signals from V2X communications, sensor fusion;
  • Performances of cooperative control systems;
  • Hierarchical and heterogeneous cooperative structures;
  • Machine learning, reinforcement learning;
  • Cooperative control, robust control;
  • Mixed traffic of autonomous and human-driven vehicles;
  • Testing and validation of connected vehicles;
  • Development frameworks, prototype constructions;
  • Potential impact of connected vehicles on traffic control.

The design of the motion of autonomous vehicles in non-signalized intersections with the consideration of multiple criteria and safety constraints is a challenging problem with several tasks. In this paper, a learning-based control solution with guarantees for collision avoidance is proposed. The design problem is formed in a novel way through the division of the control problem, which leads to reduced complexity for achieving real-time computation. First, an environment model for the intersection was created based on a constrained quadratic optimization, with which guarantees on collision avoidance can be provided. A robust cruise controller for the autonomous vehicle was also designed. Second, the environment model was used in the training process, which was based on a reinforcement learning method. The goal of the training was to improve the economy of autonomous vehicles, while guaranteeing collision avoidance. The effectiveness of the method is presented through simulation examples in non-signalized intersection scenarios with varying numbers of vehicles. Full article

In the development of autonomous vehicles, the design of real-time motion-planning is a crucial problem. The computation of the vehicle trajectory requires the consideration of safety, dynamic and comfort aspects. Moreover, the prediction of the vehicle motion in the surroundings and the real-time planning of the autonomous vehicle trajectory can be complex tasks. The goal of this paper is to present low-complexity motion-planning for overtaking scenarios in parallel traffic. The developed method is based on the generation of a graph, which contains feasible vehicle trajectories. The reduction of the complexity in the real-time computation is achieved through the reduction of the graph with clustering. In the motion-planning algorithm, the predicted motion of the surrounding vehicles is taken into consideration. The prediction algorithm is based on density functions of the surrounding vehicle motion, which are developed through real measurements. The resulted motion-planning algorithm is able to guarantee a safe and comfortable trajectory for the autonomous vehicle. The effectiveness of the method is illustrated through simulation examples using a high-fidelity vehicle dynamic simulator. Full article

Reinforcement learning-based approaches are widely studied in the literature for solving different control tasks for Connected and Autonomous Vehicles, from which this paper deals with the problem of lateral control of a dynamic nonlinear vehicle model, performing the task of lane-keeping. In this area, the appropriate formulation of the goals and environment information is crucial, for which the research outlines the importance of lookahead information, enabling to accomplish maneuvers with complex trajectories. Another critical part is the real-time manner of the problem. On the one hand, optimization or search based methods, such as the presented Monte Carlo Tree Search method, can solve the problem with the trade-off of high numerical complexity. On the other hand, single Reinforcement Learning agents struggle to learn these tasks with high performance, though they have the advantage that after the training process, they can operate in a real-time manner. Two planning agent structures are proposed in the paper to resolve this duality, where the machine learning agents aid the tree search algorithm. As a result, the combined solution provides high performance and low computational needs. Full article
