Pagliarecci, Nico. "On the understanding of the vehicle-driver interaction using the objectification of subjective assessment : application to the tire development process." Thesis, Mulhouse, 2020. http://www.theses.fr/2020MULH4104.
Full textThe tire is heavily involved in the performance of a vehicle. Vehicle's fuel consumption (rolling resistance, aerodynamics), noise, comfort, handling and safety are related to the tire chosen. By using objective measurements, it is possible to predict some of those features but for some others like handling we cannot really predict the subjective evaluation made by experienced test drivers. Trial/error methodology is sometimes applied to identify tire potential and to gauge the tire performance related to specific designs and mechanical characteristics.Today, in the automotive industry, the evaluation of vehicle and tire handling performance is still largely performed on a subjective basis by experienced test drivers. This is justified by the fact that customer perception of vehicle performance is also made subjectively and, no reliable relationship has been found to relate objective performance measures to the human perception of performance.An extensive literature review on the objectification of subjective assessment, the vehicle-driver interaction, the vehicle dynamics simulation and the explorative multivariate data analysis as well as statistical hypothesis testing is the first research step aimed to investigate the methodologies, the data analytics and statistical tools used by other researchers.Based on the literature review, the thesis proposes a methodology that allows to translate subjective evaluations into objective metrics (vehicle environment as well as vehicle-tire environment) enabling the prediction of the outcome of a subjective test by using objective measurements leading to a reduction of the iterations during the tire development process. The choice of the most relevant vehicle dynamics model’s complexity depicts the main tire mechanical features affecting the handling performance and their effect on the objective metrics of interest. Specific experimental vehicle dynamics maneuvers have been selected for this study with the aim of unpacking the complexity of the subjective handling assessment without being simplistic and paying attention to interconnectedness of the different variables and their interplay with contextual factors.In the frame of the above-mentioned correlation study, the role of the driver in the driver-vehicle system is investigated. The results presented show that, with the chosen methodology, it is possible to gain insights on the driver’s testing strategy identifying the main vehicle responses affecting all the stages of the subjective evaluation. To deepen and strengthen the understanding of the driver’s role, two panel studies involving professional and non-professional drivers have been carried out. Those allowed the study and analysis of the vehicle-driver interaction in terms of proprioception and vision, audio-visual influences and aftereffects in motion

Full textThis thesis concerns the improvement of brushless DC motor performance, called Brushless motor (BLDC), and of an electric vehicle using this type of motor (BLDC) for its propulsion. The aim of this thesis is to provide new methods dedicated to the reduction of problems concerning this type of engine and thus increase its efficiency to achieve a lower electric vehicle energy consumption. This is done while taking into account the different parameters that come into consideration when rolling a vehicle, namely the resistive forces such as aerodynamic forces, rolling, slope, and acceleration. An experimental platform was thus implemented and on which the elaborated methods were implemented and proved after the analysis of the analytical and simulation results. These were developed on the MATLAB / Simulink environment. The proposed methods deal with problems related to current ripple, current peaks, and also the appropriate control mode for increased efficiency

Full textElectromagnetic Compatibility (EMC) and Radiofrequency (RF) constraints in the automotive industry are particularly stringent and require the implementation of methodologies that cover the entire project’s development throughout the design phase. In order to predict the installed performance of products in their operational environment, we developed actions that cover the coupling risks between components and their surroundings, these couplings having an impact on both EMC and functional aspects of RF systems. The main difficulty in designing RF equipments is that the specification, which means the final requirement, is described in relation to the whole vehicle. But during the development phase of a new product, the vehicle is often unavailable, or practically doesn’t exist yet. Furthermore, accelerating the development of vehicles allows less to wait for the final implementation, to be able to tune the product to its environment. A reason that pushes us to develop tools adapted to those needs. This thesis proposes a simulation methodology to predict the behavior of RF receivers taking into account their operational environment. The first chapter is devoted to a panel drawing up the generalities of antennas, the state of the art in system integration and a brief description of numerical methods. Then, the second chapter is devoted to the "detuning" phenomena, where we list, through an experimental approach, the parameters causing the detuning of an antenna. In order to obtain a predictive tool, we model the equipment using a circuit approach, to better quantify these parameters and to propose design rules in the early phases of projects development. Finally, the third chapter is devoted to the radiation analysis. It plans to expand the use of numerical simulation to predict the radiation patterns of RF devices. In this context, we propose a simplified model of an antenna that can be easily integrated at vehicle level

Full textThe work presented in this manuscript takes part in the context of driving simulation and more specifically in the one of dynamic driving simulators used for the validation of advanced systems and the autonomous vehicle. In order to address the issues of performance and motion perception, we have presented different approaches to improve the Motion Cueing Algorithms (MCA). All our studies show that the model predictive control (MPC) strategy is the best choice to MCA on high-performance driving simulators. Indeed, compared to other strategies, it allows to better take advantage of the workspace without endangering the simulator and/or the driver. However, in this MCA, the real-time optimization and the perception model must be guaranteed in order to improve the driver's immersion in the virtual environment. Therefore, we compared different techniques to solve constrained optimization problems. We proposed a based optimization technique, which provides an intuitive and fast solution to the MPC constrained optimization problem. Finally, we established recommendations for MCA parameterization according to the self-declared driving behavior allowing a better perception of motion in a driving simulator, in interactive driving and in autonomous mode

Full textLa méthodologie proposée, nous permet d'engager des négociations entre les architectes de l'automobile et les ingénieurs mécaniciens sur le respect ou le non-respect de contraintes d'architecture d'un sous-système ou d'un organe, ainsi que sur l'atteinte des cibles du cahier des charges en ce qui concerne les performances vibro-acoustiques.
Le cadre méthodologique proposé se compose de cinq étapes : (1) la modélisation du problème de conception, comprenant (a) la modélisation des performances vibro-acoustiques et (b) la modélisation des contraintes d'architecture (2) la métamodélisation (approximation mathématique) du problème de conception résultant en utilisant les métamodèles de type kriging, (3) la formulation du problème de conception sous la forme d'un problème d'optimisation multi-objectifs, (4) la génération grâce au métamodèle de la frontière de Pareto de ce problème d'optimisation multi-objectif par la méthode des contraintes normales et normalisées, (5) une étape de négociation entre les contraintes d'architecture et les performances du sous-système mécanique.
Pour gérer le problème des contraintes d'architecture, dans la phase de conception préliminaire, nous introduisons une méthode pour exprimer, par un critère dit d'architecture, le respect ou le non-respect des contraintes géométriques. L'originalité de cette méthode consiste dans le fait de migrer l'étape de l'allocation de volumes enveloppes sous un système de CAO vers un système d'IAO plus accessible aux ingénieurs puisque c'est dans ce système qu'ils gèrent leurs modèles éléments finis.
Nous introduisons, en outre, une méthode d'agrégation des performances vibro-acoustiques d'un sous-système mécanique en un seul critère (indicateur) à valeur réelle. Cette technique permet une réduction efficace de la dimension importante d'un problème de conception lié à l'étude d'un sous-système mécanique avec des multiples performances vibro-acoustiques.
L'application de la méthodologie à un cas d'étude, dans le domaine automobile, a permis de démontrer son efficacité à améliorer sensiblement les performances vibro-acoustiques d'une caisse en blanc (caisse nue d'une automobile) tout en respectant des contraintes d'architecture serrées à cause d'un volume enveloppe alloué au groupe motopropulseur du véhicule.
Finalement, avec ce cadre méthodologique, les négociations entre les architectes et les ingénieurs ne sont plus fondées sur des jugements qualitatifs, mais elles sont à présent fondées sur des critères quantitatifs à la fois pour les contraintes d'architecture et les performances mécaniques.

Full textThe main object of this thesis is to determine the methods and innovating processes, in the domain of the antenna system integration, based on an optimal exploitation of a vehicle Spherical Near-Field Facility (SNFF). First of all, we focus our works on the study and the utilization research of spherical near-field techniques for in-situ antennas measurements. The second part is devoted to the works that we have realized and the obtained results in the field of FM broadcasting service. We propose some new evaluation methods of FM systems on board in end-using conditions. The original approach is based on the association of the intrinsic performances of the radiating element on vehicle with the final mobile communication environment. Finally, the third part of our works concerns the different propositions of original utilization of the SNFF tool for the study of the sensitivity at radio-electrical sources
