Underwater marine applications are nowadays branching into various fields covering larger and deeper zones. Performing the required tasks with the aid of AUV flotillas is a real challenge. However, the advantages of using such a new technology are numerous. Firstly, this would highly reduce the cost of the mission thanks to the distribution of this former among the various AUV: the loss of one AUV or its bad functioning will not degrade the performance of the flotilla in general. Secondly, the use of a flotilla reduces the execution time of a mission given the parallelization of certain tasks. Finally, any mission can be accomplished by the flotilla by taking into consideration the specificity of each AUV. In fact, each of these vehicles holds different characteristics rendering the global architecture heterogeneous and therefore applicable in different contexts. However, the methods concerned with multi-AUV cooperation are hindered by two main limitations: (1) the number of communications induced and (2) the management of the heterogeneity in the flotilla.The proposed approach aims at responding to these challenges. The principal idea is to combine this reactive cooperational approach with an organizational one. The reactive cooperational approach allows the exchange of simple communication signals. However, it does not help in solving the problems of cooperation that are very constrained and that mainly concern the spatial coordination of homogeneous vehicles. The first contribution in this thesis is the extension of the satisfaction-altruism approach. A new reactive decisional mechanism capable of considering the cooperative actions of various natures is proposed. The second contribution consists in specifying the context of reactive interactions based on an organizational approach. The organizational model Agent/Group/Role is used in order to have an explicit representation of the flotilla. The concepts of "group" and especially "role" are used in the attribution of the communication signals allowing the accomplishment of heterogeneous interactions with a big modularity. A new concept is therefore born and is integrated in a new software architecture called REMORA intended to equip autonomous underwater vehicles. This proposed new method has been validated through various numerical simulations in different scenarios putting at stake heterogeneous AUV

Autonomous and connected mobility has become a major socio-economic challenge. However, the safety and security of autonomous vehicles are barriers to the deployment of this type of vehicle. In this context, the aim of this thesis is to contribute to the development of sensor fault diagnosis methods, and to implement inter-vehicle cooperation to improve the localization performance of these autonomous vehicles.Concerning the diagnostic aspect, we propose to couple both model- and data-based techniques to produce a sensor fault-tolerant cooperative localization solution. Given the stochastic nature of the measurements, we have chosen the informational formalism, which provides measures of dissimilarity between probability distributions called divergences. In this thesis, we use the Jensen-Shannon divergence to synthesize fault indicators, the residuals. Thresholding these residuals enables us to detect and isolate sensor faults. We have also studied the contribution of learning to diagnostic decision-making. Two models, one for detection and the other for isolation, were trained, using different machine learning tools (multi-layer perceptron, decision tree and logistic regression).Inter-vehicle cooperation has led to the implementation of a decentralized architecture for multi-sensor data fusion and diagnosis. This inter-vehicle cooperative aspect enables informational redundancy, contributing to improved performance in pose estimation and diagnosis. The data generated by this architecture has been used to implement a federated learning paradigm.The proposed methods were developed, tested and evaluated on a set of scenarios with real and injected sensor faults. These scenarios were created using a database of real data acquired with a robotic platform designed during the thesis. The PRETIL platform comprises three communicating and instrumented robots

The continuous increase in the number of vehicles has constantly led to innovation to improve the regulation of road traffic. Today, vehicle automation and inter-vehicular communication make possible a new approach: the autonomous and cooperative intersection (ACI) in which autonomous vehicles communicate to negotiate their right of way at the intersection. Theoretically more effective, safer and more economical than traditional approaches, its implementation and deployment constitute a scientific and technological challenge. In this paper, we propose several contributions supporting this development: a longitudinal and lateral vehicle control strategy designed to work with information discrete and suffering from latency (coming from wireless communication or satellite positioning), a preventive solution of the risks of deadlock specific to the ACI, and finally the implementation and testing of a real prototype of ACI with three autonomous vehicles. An exploratory work is then provided to generalize the principles of the ACI, in order to automate and optimize the operations of lane change and insertion

This thesis studies the technical and economical interaction between electric vehicles and electrical networks. The recent development of electric mobility leads to the analysis of potential impacts of electric vehicle charging on the electrical networks, but also to the possible support that these particular electric consumers could provide in the future smart grids. In this direction, most of the results given in this thesis also apply to a washing machine, a water-heater, a TV, as soon as these equipments are capable of being smart! When the decisions of flexible electric consumers interact, the considered framework naturally offers a unique exercise area for the tools of game-theory. The interpretation is straightforward when the considered problem is strategic by definition, but these tools allow also shedding light on other aspects: algorithmic coordination, information exchange, etc. The description of the benefits of using game-theory in this context is the aim of this work. This is done according to three aspects. In these three directions, a particular attention is drawn to the case of rectangular charging profiles, which are very practical, but often ignored by the literature. First, algorithmic issues arise when coordinating the charging of electric vehicles in a same area of the electrical network. A charging algorithm is proposed and analyzed. This is done by studying an underlying auxiliary game. This game is proved to belong to the class of potential games under very general physical and economic assumptions. In turn, it inherits from the strong properties of this class of games, namely convergence and an efficiency result in the case of a large number of electric vehicles. Considering information exchange, a model is proposed to design a good communication scheme between an operator of the electrical system and an electric vehicle. Both agents have an interest in exchanging information to schedule optimally the charging profile of the electric vehicle but they do not share the same objective. This framework is closely related to Cheap-talk in game theory and to quantization in signal processing. Amongst others, this work explains interesting connections between both topics. Furthermore, a method, which is used offline, is given to obtain a good communication mechanism between both agents. Finally, game theory is used in its traditional form, studying the strategic interaction when groups of a large number of electric vehicles – seen as fleets – coexist with individual vehicles. This allows the application of the very recent concept of composite games. In the three parts of the work, simulations are conducted in a French realistic distribution network, which could be the first part of the electrical system severely impacted by a non-coordinated charging. This highlights the robustness of rectangular charging profiles against forecasting errors on the parameters of the models
