Повний текст джерелаParmi les techniques de commande non linéaire envisageables, celles basées sur les modèles flous de type Takagi-Sugeno (TS) ont été retenues. Ils sont composés de modèles linéaires interconnectés par des fonctions scalaires non linéaires ayant la propriété de somme convexe.
L'étude de la stabilité et de la stabilisation de tels modèles se fait à l'aide de la seconde méthode de Lyapunov. Dans le souci d'adjoindre des notions de robustesses et/ou de performances, plusieurs solutions sont envisageables. Celle retenue dans ce mémoire fait appel à des modèles incertains et à un placement des pôles des modèles linéaires dans des régions convexes pré-spécifiées du plan complexe. Des conditions suffisantes sous forme d'inégalités matricielles linéaires qui permettent de garantir ces propriétés dans le cas général des modèles TS sont proposées. Elles sont ensuite aussi bien utilisées dans le cas d'une régulation d'inter-distance seule que pour l'attelage virtuel complet. Les résultats obtenus sont proposés en simulation et en temps réel sur un véhicule prototype spécialement instrumenté.

Повний текст джерелаDevelopments in the Intelligent Transportation Systems (ITS) field show promising results at increasing passengers comfort and safety, while decreasing energy consumption, emissions and travel time. In road transportation, the appearance of automated vehicles is significantly aiding drivers by reducing some driving-associated tedious tasks. However, there is still a long way to go before making the transition between automated vehicles (i.e. vehicles with some automated features) and autonomous vehicles on public roads (i.e. fully autonomous driving), specially from the motion planning point of view. With this in mind, the present PhD thesis proposes the design of a generic modular architecture for automated vehicles motion planning. It implements and improves curve interpolation techniques in the motion planning literature by including comfort as the main design parameter, addressing complex environments such as turns, intersections and roundabouts. It will be able to generate suitable trajectories that consider measurements' incertitude from the perception system, vehicle’s physical limits, the road layout and traffic rules. In case future collision states are detected, the proposed approach is able to change---in real-time---the current trajectory and avoid the obstacle in front. It permits to avoid obstacles in conflict with the current trajectory of the ego-vehicle, considering comfort limits and developing a new trajectory that keeps lateral accelerations at its minimum. The proposed approach is tested in simulated and real urban environments, including turns and two-lane roundabouts with different radii. Static and dynamic obstacles are considered as to face and interact with other road actors, avoiding collisions when detected. The functional architecture is also tested in shared control and arbitration applications, focusing in keeping the driver in the control loop to addition the system's supervision over drivers’ knowledge and skills in the driving task. The control sharing advanced driver assistance system (ADAS) is proposed in two steps: 1) risk assessment of the situation in hand, based on the optimal trajectory and driving boundaries identified by the motion planning architecture and; 2) control sharing via haptic signals sent to the driver through the steering wheel. The approach demonstrates the modularity of the functional architecture as it proposes a general solution for some of today's unsolved challenges in the automated driving field

Повний текст джерелаMy thesis can be summarized in three parts: The first part consists in studying the impact of the low speed automation on driver safety, traffic capacity, fuel consumption and vehicle emissions. As a first step, a pattern of mixed road traffic is established. This one is defined by the coexistence of two driving styles: the first one is the manual and the second one is the automated. Secondly, the scenarios and the associated indicators have been developed. In this context a traffic simulator was developed with the C programming language using the OpenGl library for the graphical interface. Results show that the increase of automated vehicles presence traffic safety increases in case of accidents scenarios as well as in the case of without accidents. Moreover, the impact of automated vehicles on fuel consumption and pollutant emissions only appears when it comes to long path. The second part of my thesis consists in improving the Intelligent Driver Model (IDM) model, Adaptive Cruise Control (ACC) to represent the automated driving in traffic, to overcome its drawbacks. In this context, a new version is developed. The main idea is to take into account not only the state of the preceding vehicle but also the tail vehicle. This new model shows better performance in queue stabilization in terms of accelerations and velocities. The third part is devoted to the macroscopic traffic modeling in which we study the fundamental diagram. The new developed macroscopic model is based on microscopic data given by the Intelligent Driver Model simulation. Then, the traffic density and velocity were identified by non-linear regression. The new macroscopic velocity-density model has three advantages: Knowledge of the stable velocity and density within the first seconds of simulation by identifying. Ability to find existing models in the literature by setting some of its parameters. Calibration with a minimum of error for different traffic situations (eg congestion, free)

Повний текст джерелаAIn our study, we consider two optimization problems in automated container terminals at import; the first is the vehicle scheduling problem; and the second is the integrated problem of location assignment and vehicle scheduling. In the first part of our study, we propose different traffic layout adapted to the two studied problems and to every kind of automated container terminal. We also introduce relevant reviews of literature treating the optimization of container handling systems at maritime terminal, the optimization of general automated guided vehicle system and the multi-objective optimization in general, and in particular context of maritime container terminals. In the second part, we resolve the planning of QC-AV-ASC (Quay Cranes-Automated Vehicles - Automated Stacking Cranes). We present an effective model for every kind of traffic layout. Moreover, we propose an efficient bi-objective model which is important to determine the optimal storage time and the minimal number of required AVs. CPLEX resolutions are used to prove the efficiency of our modelling approach. In the third part of this thesis, we explore a problem which has not been sufficiently studied: the integrated problem of location assignment and vehicle scheduling (IPLAVS), in Maritime Automated Container Terminal (MACT) at import. This part represents a new and realistic approach of MACT optimization considering mono-objective and multi-objective aspect

Повний текст джерелаConsiderable research and development efforts are currently focused on automated vehicles that could free drivers from driving tasks and allow them to perform new activities (e.g. working, sleeping). Such activities would benefit from new seating configurations. However, even if a high level of safety is expected for these future vehicles, accidents will continue to occur. Current protective devices are designed for a driving position. They may require modifications to maintain the current level of protection for new occupant positions. This thesis aims to identify the risks and opportunities in terms of occupant protection associated with new positions that could appear with automated vehicles. The analyses used digital human models for applied traffic safety which have proven to be a relevant risk assessment tool. Particular attention was paid to assessing the validity of the models after repositioning. The work provided a better understanding of the restraint mechanisms in reclined configurations during a frontal impact. These positions appear to be critical with a difficult restraint of the pelvis or loading of the lumbar spine depending on the seat angle. The occupant response was also significantly affected by the initial position of the pelvis. These results can be used to help design and evaluate new restraint systems. In order to better understand the comfortable position in these reclined configurations, an experimental study was carried out using a multi-adjustable seat. These experiments enabled, on the one hand, to identify the comfort seat configurations, and on the other hand to establish the relationships between these seat configurations and the position of the internal skeleton and in particular for the pelvis. These results can in particular help the positioning of occupants during physical or digital tests. Overall, this work shows the strong interaction between comfort and safety for the design of new passenger cars

Повний текст джерелаThe central theme of the thesis concerns the role of acceptability in the interaction between a conventional vehicle driven by a human and an automated vehicle. A meta-analysis synthesizing the determinants of the acceptability of a new technology is a first study. The results showed that acceptability was predicted by six factors: behavioural intention, perceived usefulness, perceived ease of use, attitude, social influence and feeling of control. A second study was conducted to evaluate the effect of the acceptability judgment on the difference in be-haviour stated by the driver of a conventional vehicle during interaction with an automated vehicle. The results showed that low acceptability is associated with cautious behaviour towards the automated vehicle. A third study, conducted on a driving simulator, showed that conventional vehicle drivers who have a high acceptability behave in the same way towards an automated vehicle and a conventional vehicle. To conclude, this thesis questions the role of the acceptability of a technologic device in the interaction with it

Повний текст джерелаAutonomous driving technology is attracting increasing interest from automobile manufacturers, researchers, authorities, and the general public due to its promises in enhancing road safety, providing mobility for the elderly and individuals with reduced mobility, improving energy efficiency, and reducing emissions. However, the full deployment of these vehicles relies on their reliability in all situations, necessitating driver supervision. This raises critical questions about human-machine interaction, particularly concerning sharing control between the automated driving system and the driver, as well as conflict management.The thesis is part of the ANR-CoCoVeIA project (2019-2024), coordinated by LAMIH (Cooperation Driver-Autonomous Intelligent Vehicle). The main objective of this project is to introduce self-learning capabilities into level 2 autonomous vehicles to enhance their skills while adhering to road safety rules. The thesis focuses specifically on managing interactions between the automated system and the driver, with the goal of improving its effectiveness, enhancing driving performance, and promoting the driver's acceptance of the system.To achieve these goals, a multi-level evolutionary cooperation architecture is proposed in the first part of the thesis. This architecture aims to optimally adapt the behavior of the autonomous vehicle to a driver's preferred driving style while ensuring safe and efficient driving. The second part of the thesis delves into personalizing lane change assistance systems, using a stochastic gradient descent-based learning approach to adjust parameters based on the driver's preferences, relying on the detection of their lane change intentions.To address conflicts between the driver and the autonomous driving system, the thesis explores three robust optimal control approaches for linear time-varying parameter systems (LPV) represented in the Takagi-Sugeno (T-S) fuzzy form. The first approach focuses on adaptive shared control by real-time adjustment of a multi-objective cost function based on driver availability and risk assessment. The second approach introduces a driver's dynamic model, with parameters identified online, allowing continuous adaptation to the driver's characteristics. This model is used to develop an adaptive shared control system for lane-keeping, taking into account the neuromuscular dynamics of the driver's parameters. The final approach aims to entirely eliminate conflicts between the driver and the lane-keeping system by combining an adaptive cost function with a dynamic driver behavior model.For the design of the LPV shared controller, stability conditions for closed-loop adaptive shared control (LPV) for all three approaches are established using Lyapunov stability arguments and formulated as a linear matrix inequality (LMI) optimization problem that can be numerically solved using convex optimization algorithms. Experimental validations and user testing experiments were conducted using the SHERPA-LAMIH dynamic driving simulator to assess the acceptability of these approaches, demonstrating their effectiveness in improving safety and driving comfort and validating all of the proposed approaches

Повний текст джерелаIn the framework of this dissertation, we will focus on Eco-driving and, particularly on eco-maneuvers, taking into account constraints associated to infrastructure and traffic, as well as with drivability. Additionally, we will take inspiration on Cognitive Principles for the algorithm design; it will allow to reinforce algorithm’s effectiveness and modularity. Easiness of calibration will also be an important concern for our work. Our whole discussion focuses on Battery Electric Vehicles. However, the proposed principles may be adapted for their application for other types of powertrain.Our work treats three main topics: on one side, Driving Ergonomics, allowing to determine some criteria on drivability ; we will also propose a modelling of the driver allowing to take into account ergonomics considerations. Finally, we will assess our hypothesis with respect with driver behavior on real situations, by applying an innovative methodology for the analysis of actual driving records. Next we will focus on Energy Model of the vehicle and of driving maneuvers, as well as to the assessment of energy gain potential associated to several Eco-driving strategies; the origin of these gains is also studied. Finally, we propose a Control Algorithm allowing to execute driving eco-maneuvers, while taking into account drivability criteria. The global algorithm structure is based on cognitive principles presented earlier. These function consists of several subsystems, which improves its modularity, and enforces its potential to operate within real-time constraints, and simplifies calibrations ; these both are major advantages for an industrial application

Повний текст джерелаGiven rapid advancement of automated driving (AD) technologies in recent years, major car makers promise the commercialization of AD vehicles within one decade from now. However, how the automation should interact with human drivers remains an open question. The objective of this thesis is to design, develop and evaluate interaction principles for AD systems that can cooperate with a human driver. Considering the complexity of such a human-machine system, this thesis begins with proposing two general cooperation principles and a hierarchical cooperative control architecture to lay a common basis for interaction and system design in the defined use cases. Since the proposed principles address a dynamic driving environment involving manually driven vehicles, the AD vehicle needs to understand it and to share its situational awareness with the driver for efficient cooperation. This thesis first proposes a representation formalism of the driving scene in the Frenet frame to facilitate the creation of the spatial awareness of the AD system. An adaptive vehicle longitudinal trajectory prediction method is also presented. Based on maneuver detection and jerk estimation, this method yields better prediction accuracy than the method based on constant acceleration assumption. As case studies, this thesis implements two cooperation principles for two use cases respectively. In the first use case of highway merging management, this thesis proposes a cooperative longitudinal control framework featuring an ad-hoc maneuver planning function and a model predictive control (MPC) based trajectory generation for transient maneuvers. This framework can automatically handle a merging vehicle, and at the mean time it offers the driver a possibility to change the intention of the system. In another use case concerning highway lane positioning and lane changing, a shared steering control problem is formulated in MPC framework. By adapting the weight on the stage cost and implementing dynamic constraints online, the MPC ensures seamless control transfer between the system and the driver while conveying potential hazards through haptic feedback. Both of the designed systems are evaluated through user tests on driving simulator. Finally, human factors issue and user’s perception on these new interaction paradigms are discussed
