Choi, Sungwoo. „Estimation et contrôle pour le pilotage automatique de véhicule : Stop&Go et parking automatique“. Paris, ENMP, 2010. http://www.theses.fr/2010ENMP0025.
Der volle Inhalt der QuelleThe purpose of my thesis, realized in collaboration with VALEO, is to develop advanced driver assistance systems to increase safety and comfor t in vehicles. To summarize, it is to develop algorithms of a longitudinal control such as Adaptive Cruise Control (ACC) allowing to follow in real time with a safety a leading vehicle and more generally strategies to lower Speed (Stop&Go) for the evolution of vehicle in urban environments. At low speed, it should also consider the problem of parallel parking assistance. First of all, the longitudinal control algorithms (ACC and Stop &Go) were studied. In order to increase system robustness against measurement noise, neglected external dynamics such as the slope of the road, rolling resistance and aerodynamic forces, etc. , as well as uncer tainties related to the engine/brake model, an unfied algebraic approach for estimation and model-free control is applied. Regarding the low-speed automation of parallel parking, we proposed a general solution based on a geometric approach. Our local planner can generate a geometric path consisting of circular arcs of minimum radius and straight lines for a parking space whose length is greater than the diagonal of the vehicle. It should be noted that our method is independent of the initial position of the vehicle if its initial position is parallel to the parking lot. An algorithm for geometric path planning of the parallel parking problem according to the length of the parking space was also developed. A theoretical study of the complexity of our method in terms of the number of maneuvers shows that it requires less maneuvers than classical methods in practical cases

Der volle Inhalt der QuelleThis dissertation explores the field of diagnosis applied to the automotive industry based on SIDIS Enterprise developed by Siemens AG. At the beginning we analyzed the importance of the after-sale world for car manufacturers and in the automotive value chain, as well as the requirements of manufacturers for computer assisted diagnostic tools. One important requirement for manufacturers was to limit the post development cost of models for the diagnosis. Furthermore, the analysis shows that electronic failures increase as well as electronic equipment with the consequences that the failure localization becomes more and more complex. The need for computer assisted tools for car manufacturers was therefore essential in order to save time for the fault localization, for the client’s satisfaction, and for the image of the brand. This thesis leads to a global modular framework for automotive diagnosis composed by: a perceived symptom search engine, an automatic ODX exchange system, a hybrid heuristic and model based diagnostic strategy, a feedback engine. The first module is concerned with the interpretation and mapping of qualitative failure descriptions in natural language. The second module allows authors of the database and knowledge network to automatically import Electronic Control Units description files. The last ones are concerned with the development of a diagnosis algorithm, which combines all different knowledge sources and benefits from the return of experience for the auto completion of the models. All these modules contribute to the overall reduction of the costs of models for the diagnosis

Der volle Inhalt der QuelleOur work of thesis concerns the systems of assistance to the drivers. In the objective to increase safety, we propose to the driver a contribution of an anticipated knowledge of the road by a system of cartography embarked but also of models of prediction of dynamics vehicle for the anticipation of a situation of danger. The system of assistance to driving is based on the evaluation in real time of the dynamic situation of the vehicle. The original introduction of a virtual vehicle (Avatar), projected in front of the real vehicle, indeed makes it possible to pre-empt the adequacy of the dynamic state of the vehicle compared to the road, in order to avoid the situations of accidents. The evaluation of the adequacy of the dynamics of the vehicle with its environment requires the development of models of vehicles sufficiently reduced to be used in line (observer, estimator, calculation of criteria). We thus analyzed the situations of conduits and defined a whole of relevant situations, whose association makes it possible to reproduce a real route of the vehicle. For that we developed an observer multimodèle by sliding modes in particular for the estimate of the adherence and the attributes of the road. The system presented offers an active help to the driver, within this framework of the assistance to braking, we proposed a strategy of order for the regulation of the slip in the case of a braking by system ABS. The goal is to maximize braking by ensuring a maximum of adherence, and thus to reinforce the actions of the driver, in the first additive phases (progressive actions of the RCC). In the event of evolution of criticality, the system takes completely charges braking of it by fixing the instruction

Der volle Inhalt der QuelleIn recent years, connected vehicles have paved the way for safer and more automated transportation systems. These vehicles rely heavily on Advanced Driving Assistance Systems (ADAS) and use various sensors like radar, camera, LiDAR, and V2X to ensure 360° safety type of cocoon around the vehicle. While artificial intelligence and deep learning have enabled real-time object detection and identification using cameras and LiDAR, the use of such algorithms on radar data is still limited. Radar sensors offer advantages, such as working in challenging weather conditions and providing good performance in distance, angular and speed resolution, at a lower cost than LiDAR. However, radars output relatively low content information regarding the detected targets and several pre and post-processing steps are required to obtain those. Since the processing steps filter the raw signal returned by objects, it can affect the performance of AI algorithms. This PhD aims to develop new deep learning algorithms explicitly tailored for raw radar data to integrate them into automotive systems. These algorithms will detect and identify objects in complex environments. Additionally, this thesis will explore the optimal types of radar data and pre-processing steps for achieving the best performance. The algorithms will have to meet automotive constraints, including low power consumption, simplicity, and fast response times
Loreau, Tanguy. „Construction automatique de modèles multi-corps de substitution aux simulations de crashtests“. Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLC082/document.
Der volle Inhalt der QuelleAt Renault, to fulfill upstream studies, teams in charge of crashworthiness use very simple models to pre-size the vehicle. Today, these models are built from the physical behavior of only one or some reference vehicles. They work and allow to size the project. But today, the company wishes to build its upstream models using all its vehicles. In other words, it wishes to get an automatic method to analyze crashtests simulations to capitalize their results in a database of simplified models.To meet this goal, we decide to use the multi-body model theory. We develop a method to analyze crashtests simulations in order to extract the data required to build a surrogate multi-body model : CrashScan. The analysis process implemented in CrashScan can be split into three major steps.The first one allows to identify the low deformed zones on a crashtest simulation. Then, we can build the topological graph of the future surrogate model. The second step is to analyze the relative kinematics between the low deformed zones : major directions and deformation modes (e.g. crushing or bending) are identified analysing relative movements. The last step is to analyze strengths and moments located between the low deformed zones, viewed in the frames associated to the major directions of deformations in function of the deformations. This allows us to identify equivalent Bouc-Wen hysteretic models. These models have three parameters that we can use : a stiffness, a threshold strength before plastification and a strain of hardening. These parameters can directly be used by upstream studies experts.Finally, we build multi-body models for three different use case. We compare them to their reference over the results they produce for the upstream criteria : models generated with CrashScan seems to grant the precision and the fidelity required to be used during automotive development's upstream phases.To continue this research work and get an industrial solution, there are still some locks to lift, the main ones are : synthesis of any movement into six elementary ones and multi-body synthesis on elements other than beams
Losero, Rémi. „Contrôle en couple et en vitesse du glissement d'un embrayage simple ou double dans une transmission automobile“. Thesis, Valenciennes, 2016. http://www.theses.fr/2016VALE0005/document.
Der volle Inhalt der QuelleThis PhD has been done in an industrial framework with the so-called automotive equipment manufacturer Valeo and the laboratory of Automatic Control, Mechanics, Informatics and Human Sciences LAMIH UMR CNRS 8201 of Valenciennes, France. The issues of this PhD are closed to the industrialization context such as the clutch torque estimation during the gear shifting phases in a dual clutch transmission and the clutch slip speed control. In order to solve the inline clutch torque estimation issues, a virtual torque sensor has been developed. On one hand, this virtual sensor is composed of a shaft torsion angle estimation based on a method of virtual tooth adding into the encoder sensors. On another hand, discrete angular domain unknown input Takagi-Sugeno observer is used for the estimation of the dynamic part of transmitted torque. This methodology has permitted the estimation of the transmitted clutch torque of a dual clutch transmission in simulation. The simulation results have been obtained on a simulation platform provided by Valeo, including a complete vehicle model. The methodology has also been tested on real data of a dual mass flywheel angular deflection. Thus, online estimation of instantaneous acyclic engine torque and transmitted clutch torque has been obtained. Concerning the slip control, a robust control strategy against the external disturbances leaded to the driver and the system parameters incertitude has been developed. This strategy permits to ensure the required specifications in simulation. The strategy has been also validated on vehicle during track trials

Der volle Inhalt der QuelleAn embedded system is a system that performs a specific task and has a computer embedded inside. In the automotive sector, the amount of embedded systems in the vehicle has risen dramatically in recent years and is set to increase. They deal essentially with safety, comfort, and driving assistance. Furthermore, the increase in number and complexity of the systems is associated with a growth in software. As a consequence, their management (system and software) have become more and more complex and problematic. Also, the competition and time-to-market in the automotive industry are very tough. Thus, to guarantee the efficiency and reliability of the embedded systems in the vehicle in general and the software in particular, in view of the complexity as well as the competition and time-to-market law, new development methods should be considered. Therefore, new development methods including new standards, and automatic approaches have emerged over the last years. In the particular case of embedded software verification and validation, one of the most critical activities that has experienced a significant progress is test case generation with the advent of automatic approaches. Despite this, these approaches are not widely used or are not well adapted in industrial context. In that context, our goal in this PhD. thesis is to propose a new verification and validation approach, based on automatic test case generation of embedded embedded. Thus, we have set up an approach that automatically generates test cases, with respect to the MC/DC criterion, from abstract models of the software specifications expressed in the form of state-transition models
