Abstract
This paper investigates the advantages of using communication supported by information from vehicle sensors to improve the performance of the High-Density Platooning (HDPL) application. HDPL is one of the most promising applications in the field of cooperative driving. The goal of this application is to improve fuel and road efficiency without impairing safety. The level of efficiency improvement depends on the instantaneous channel quality. Strong multipath components, which arise from other vehicles, traffic signs, and surrounding buildings in such a highly dynamic vehicular environment, significantly influence the instantaneous link quality between communicating vehicles in a platoon. An emerging concept of vehicle sensor-aided predictive communications has shown its potential to improve direct-link communication. In this paper, the applicability of this approach is evaluated in terms of inter-vehicle distance error, which reflects the difficulties that the control algorithm has to cope with in the communications conditions. The simulation results show that the proposed sensor-based approach significantly improves the platoon performance even if affected by multiple dynamic scattering reflections at the same time.

P LATOONING is one of the most promising services in cooperative vehicle automation
In particular we investigate the following challenges and bring the following key contributions: 1) the paper highlights the challenges of High-Density Platooning (HDPL) which arise from surrounding scattering objects in terms of link-level parameters and elaborates the subsequent applicationlevel changes, i.e., target inter-vehicle distances (IVDs), acceleration, velocity, and their impact on the driving comfort level and fuel consumption
We develop here the algorithms that govern the motion of the HDPL vehicles
Summary
P LATOONING is one of the most promising services in cooperative vehicle automation. Cooperation among trucks in platoon allows for smaller headways between vehicles while assuring strict safety requirements [1]. The platoon with even further decreased headways distances is known as High-Density Platooning (HDPL). The main goals of HDPL are additional safety, increased road occupation efficiency and reduction of fuel consumption. The first two goals can be achieved by having a better coordination between road users [2] while aiming for headways below ten meters. Reduction of fuel consumption arises from multiple factors, for instance from the mitigated accordion effect or reduced
