Sistema de control de tráfico para la coexistencia entre vehículos autónomos y manuales mediante comunicaciones inalámbricas

Zusammenfassung

The need to give solution to the current problems of the transport has caused the application of new technologies to this area, giving place to the field of the Intelligent Transport Systems (ITS). Focusing on the transport by road, these problems can qualify in two fundamental issues: the reduction of the traffic congestion and the increase of the safety of the vehicles. The trend for the future is for there to be a step up from simple driving aids to automatic driving controls. One of the goals in the ITS field is to attempt to reduce the number of collisions, or at least to mitigate their consequences. Of the different solutions to these problems that have been proposed, the development of autonomous vehicles is today a particularly open field of research. There exists a great variety of solutions and applications to solve the raised problems, but it is probably the end, that is, the automatic driving of vehicles where they all converge, in the short or in the long term. But before coming to this point, we must pass for the intermediate one: the coexistence among automated vehicles and those that are guided by human drivers. Even so, this thesis presents an approximation of a system of management of traffic to allow the coexistence among automatic and manual vehicles. For it, two architectures have been defined: a general one for the management of the traffic and a local one for the control of the automatic vehicles depending on the above mentioned conditions of the traffic. For the accomplishment of the experimental part one relies on four commercial vehicles, two of them automated, and an experimental private driving circuit for the prototypes in such a way that the algorithms of control - developed through fuzzy logic - and the proposed architecture they will be tested in a real environment to validate the proposed architecture.
