Even the leading vehicle benefits from platooning and saves between 2.7% and 5.3% consumed energy. ![]() Depending on the position within the platoon, energy savings between 2.8% and 9.7% per vehicle are possible. Research has shown that the energy-saving potential for various vehicle types is significantly above the 0.5% savings threshold. According to the industry, any technology for long-distance haulage that promises energy savings is already considered to be worth investigating from a level of 0.5%. This causes approximately one third of vehicle life cycle costs. The aerodynamic drag is responsible for approximately a quarter of the energy consumption for an HGV. Although platooning is mainly considered for HGVs, it is not necessarily limited to them. Even smaller distances do not reduce energy consumption significantly more but may introduce cooling problems, especially for heavy goods vehicles (HGVs). This reduce aerodynamic drag and thus, energy consumption. The inter-vehicle distances are down to approximately 10 m, which is smaller compared to human driving. The benefit of platooning is linked to the distance between two following vehicles, i.e., the inter-vehicle distance. Automation within a platoon takes both longitudinal and lateral control into consideration. Platoons are convoys of several vehicles in which the first vehicle is driven manually and the following vehicles are automated. The presented approach was tested in simulations using Omnet++ and Simulation of Urban Mobility (SUMO). The remaining data are sent-relying on cellular infrastructure once it is available-directly between vehicles with or without the use of network involvement for scheduling. Critical vehicle data are redundantly sent while the ad hoc network is only used for this purpose. Platooned vehicles are divided into smaller groups, inseparable by surrounding traffic, and are assigned roles that determine the communication flow between vehicles, other groups and platoons, and infrastructure. To account for varying network quality and enable the coexistence of non-automated and platooned traffic, we present in this paper a new concept of platooning that unites ad hoc-in form of IEEE 802.11p-and cellular communication: feudalistic platooning. This mainly applies on entry or exit lanes, on narrow lanes, or in intersection areas: automated and non-automated vehicles in traffic do affect each other and are interdependent. However, platoons, especially if they are very long, can negatively affect the flow of traffic. However, increasing gaps result in efficiency loss and additionally compromise safety as the platoon is split into smaller parts by traffic: maneuvers, e.g., cut-in maneuvers bear safety risks, and consequently lower efficiency even further. Lacking network quality may lead to safety bottlenecks that require that the distance between the following vehicles be increased. Out of the box hybrid networks only partly eliminate shortcomings: mutual interference avoidance, data load balancing, and data dissemination must be sophisticated.
