Abstract

Vehicle platooning provides benefits that include improved road capacity and fuel efficiency. These benefits improve as vehicle spacing is reduced. Fully networked platoons further share more information among platoon members that could better inform controller decisions and detect platoon disturbances in the environment. The use of a fully networked topology in vehicle platooning has not been well studied. In this paper, we evaluate distributed controller control policies using a fully networked topology. We also present a novel control policy, called quantized constant time headway, which discretizes the velocity reference used in the constant time headway policy to gain the stability benefits of a constant distance policy. Compared to three other policies in two scenarios, our approach proved to be the only stable option that used a fully networked topology and allowed inter-vehicle spacing to adjust with platoon velocity.
