“…A linear formation of vehicles in a given lane is commonly referred to as a platoon (long-lived formation) or as a string (short-lived ad hoc formation). In [12][13], we have presented and discussed the cohort construct, which is a linear formation endowed with a specification. In addition to small inter-vehicular gaps (ivgaps), safe inter-cohort gaps (IC-gaps) have been proposed, large enough for guaranteeing that the head of a cohort never hits the tail of a preceding cohort.…”

“…The need for N2N communications has been illustrated in [18], where a solution is given to the problem of safe inter-vehicular spacing in the presence of failures of robotics equipment. N2N communications serve to achieve dependability within strings, as well as across strings by disseminating received V2V messages.…”

“…There exists literature on adaptive cruise control [29,30] as well as vehicle platooning [27,28]. In [20], the author considers vehicle platooning and lane merging, and bases his construction on distributed high level communication primitives. We consider a different failure model for which there is no deterministic implementation for these communication primitives.…”

Vehicle-to-vehicle communication is a fundamental requirement for maintaining safety standards in high-performance cooperative vehicular systems. The vehicles periodically exchange critical information among nearby vehicles and determine their maneuvers according to the information quality and the established strategies. However, wireless communication is failure prone. Thus, participants can be unaware that other participants have not received the needed information on time. This can result in conflicting (unsafe) trajectories. We present a deterministic solution that allows all participants to use a fallback strategy in the presence of communication delays. We base our solution on a timed distributed protocol. In the presence of message omission and delay failures, the protocol disagreement period is bounded by a constant (in the order of milliseconds) that may depend on the message delay in the absence of these failures. We demonstrate correctness and perform experiments to corroborate its efficiency. We explain how vehicular platooning can use the proposed solution for providing high performance while meeting the safety standards in the presence of communication failures. We believe that this work facilitates the implementation of cooperative driving systems that have to deal with inherent (communication) uncertainties. * This paper appears as a technical report [26] and as an extended abstract [23].
