We consider an asymmetric control of platoons of identical vehicles with nearest-neighbor interaction. Recent results show that if the vehicle uses different asymmetries for position and velocity errors, the platoon has a short transient and low overshoots. In this paper we investigate the properties of vehicles with friction. To achieve consensus, an integral part is added to the controller, m...

This paper introduces new mathematical tools for stabilization and asymptotic following in infinite platoons of vehicles in future automated highway systems. The platoon description, behavior analysis and control is approached in 2-D polynomial framework, that is, the dynamics of the problem are described using a fraction of two bivariate polynomials. In contrast to some previous works, the pla...

In a vehicular platoon, a lead vehicle that is responsible for managing the platoon’s moving directions and velocity periodically disseminates control commands to following vehicles based on vehicle-to-vehicle communications. However, reducing command dissemination latency with multiple vehicles while ensuring successful message delivery to the tail vehicle is challenging. We propose a new line...

To address traffic congestion in urban expressways during the transition from wide to narrow sections, this study proposed a car-following strategy based on deep reinforcement learning. Firstly, was developed twin-delayed deterministic policy gradient (TD3) algorithm, and multi-objective constrained reward function designed by comprehensively considering safety, efficiency, ride comfort. Second...

In this paper a decentralized approach to the platooning problem with nonlinear spacing policies is considered. A predecessor–follower control structure presented in which vehicle responsible for tracking of desired policy respect its predecessor, regardless action latter. From perspective geometric theory, we state necessary and sufficient conditions existence controllers that guarantee asympt...

In this report, a control system called CICC has be presented for vehicle-followig and collision-avoidance. This system contains several sub-systems, such as cruise control and distancing control, each of which has also been described. While each sub-system is designed to maintain the system stability, CICC achieves good comfort as well as sufficient capacity of avoiding collisions. The perform...

The automotive industry has experienced swift development with the rapid growth of economy. increasing number vehicles led to deteriorating road traffic conditions, increased consumption nonrenewable energy, and excessive vehicle emissions. To tackle problems fuel efficiency safety control for platoons, this study suggests a novel leader-follower optimal method platoons improve efficiency. Depe...

In recent research on modelling road collisions very little attention has been paid  to rear-end chain reaction collisions, which is characterized by more than two vehicles involved in a collision at the same time. The core aim of the present research is to develop a methodology to estimate such potential collision probabilities based on a proactive perspective, where deceleration rate to avoid...

The major benefits of driving vehicles in controlled close formations such as platoons are that of increasing traffic fluidity and reducing air pollution. While vehicle-to-vehicle (V2V) communications is requisite for platooning stability, the existing radio communications technologies (e.g., the IEEE 802.11p) suffer from poor performance in highly dense road scenarios, which are exactly to be ...
