Texto completo da fonteThe automotive squeal is a noise disturbance, which has won the interest of the research and industrialists over the year. This elusive phenomenon, perceived by the vehicle purchasers as a poor-quality indicator, causes a cost which becomes more and more important for the car manufacturers, due to client’s claims. Thus, it is all the more important to propose and develop methods allowing predicting the occurring of this noise disturbance with efficiency, thanks to numerical simulations. Hence, this thesis proposes to pursue the recent works that showed the certain contributions of an integration of uncertainties into the squeal numerical simulations. The objective is to suggest a strategy of uncertainty propagation, for squeal simulations, maintaining numerical cost acceptable (especially, for pre-design phases). Several numerical methods are evaluated and improved to allow precise computations and with computational time compatible with the constraints of the industry. After positioning this thesis work with respect to the progress of the researchers working on the squeal subject, a new numerical method is proposed to improve the computation of the eigensolutions of a large quadratic eigenvalue problem. To reduce the numerical cost of such studies, three surrogate models (gaussian process, deep gaussian process and deep neural network) are studied and compared to suggest the optimal strategy in terms of methodology or model setting. The construction of the training set is a key aspect to insure the predictions of these surrogate models. A new optimisation strategy, hinging on bayesian optimisation, is proposed to efficiently target the samples of the training set, samples which are probably expensive to compute from a numerical point of view. These optimisation methods are then used to present a new uncertainty propagation method, relying on a fuzzy set modelisation

Texto completo da fonteThis study takes place in the context of Digital Human models used to test the ergonomics of environments such as automotives in the earliest stages of the design process. Yet, these tools do not take into account the aging of the population. The car ingress and egress motions are particularly problematic for seniors. This thesis aims at analysing car accessibly movements of elderly people in order to 1/ better understand their difficulties and 2/ simulate these motions using a digital human model. Eighteen elderly and 7 young subjects participated in the experiment. Ingress and egress motions were captured for four types of vehicle and discomfort ratings were collected by a questionnaire. As age effects differ from one person to another, the functional capacities were measured using clinical tests to draw a portrait of the abilities of each elderly subject. Results of these tests are used to define 3 groups of people: those who have a functional problem, those with “mediocre” capacities and those who have good capacities. Ingress and egress motions are analysed through the interaction between the subject and the environment in order to define the constraints linked to vehicle design. Two major strategies have been observed for the ingress and egress movements. The strategies “Sit First” and “Two Legs Out” are used by people with functional problems. The strategies “Right Leg First” and “Left Leg First” are the most observed ingress and egress strategies, regardless of functional capacities. These movements are decomposed into phases for which sub-strategies are defined. The interactions between the hands and the environmental seem to play an important role. Compensation mechanisms are observed in the movements of persons with functional problems. The discomfort questionnaires show that elderly subjects face more problems when exiting than when entering a car. Discomfort ratings are influenced by the functional abilities of subjects but the results are very heterogeneous. An explanation would be that these ratings also reflect the preferences of subjects in terms of car accessibility. An external examiner would then better assess the difficulties of elderly people. The captured movements are structured in databases in order to simulate the accessibility movements of elderly using the RPx software

Texto completo da fonteAccurate prediction of driving posture is essential for vehicle interior design, especially when a digital human model (DHM) is used. Meanwhile, the car market is booming in China. Chinese drivers are different from those of European in terms of anthropometry, not only in stature but also in body proportion. How to adapt car design to the Chinese market is becoming a major issue for many car manufacturers. The present PhD thesis aims at (1) studying the effects of key vehicle interior design dimensions and anthropometric variables on driving posture, (2) developing a statistical driving posture prediction model (3) quantifying intra-(i.e. variability of the same driver) and inter-individual (variability between different drivers) variability of comfortable driving postures. The driving postures of sixty-one subjects were collected using two multi-adjustable vehicle mock-ups under four test conditions by gradually adding the number of control parameters (constraints), from the “least constrained” driving condition to the configurations close to currently existing vehicles. In addition to seat height, the effects of the longitudinal positions of clutch pedal and steering wheel as well as seat cushion angle were investigated. The subjects were divided into three stature groups (short, average and tall). A sub-sample (27 ‘French-born’ and 21 ‘Chinese born’) was constituted with similar stature distribution and quite different in the sitting stature/stature, arm length/stature and thigh length/stature ratios

Texto completo da fonteThis work presents a computer vision module capable of tracking the head motion in 3D space for drivers. This computer vision module was designed to be part of an integrated system to analyze the behaviour of the drivers by replacing costly equipments and accessories that track the head of a driver but are often cumbersome for the user. The vision module operates in five stages: image acquisition, head detection, facial features extraction, facial features detection, and 3D reconstruction of the facial features that are being tracked. Firstly, in the image acquisition stage, two synchronized monochromatic cameras are used to set up a stereoscopic system that will later make the 3D reconstruction of the head simpler. Secondly the driver’s head is detected to reduce the size of the search space for finding facial features. Thirdly, after obtaining a pair of images from the two cameras, the facial features extraction stage follows by combining image processing algorithms and epipolar geometry to track the chosen features that, in our case, consist of the two eyes and the tip of the nose. Fourthly, in a detection stage, the 2D tracking results are consolidated by combining a neural network algorithm and the geometry of the human face to discriminate erroneous results. Finally, in the last stage, the 3D model of the head is reconstructed from the 2D tracking results (e.g. tracking performed in each image independently) and calibration of the stereo pair. In addition 3D measurements according to the six axes of motion known as degrees of freedom of the head (longitudinal, vertical and lateral, roll, pitch and yaw) are obtained. The validation of the results is carried out by running our algorithms on pre-recorded video sequences of drivers using a driving simulator in order to obtain 3D measurements to be compared later with the 3D measurements provided by a motion tracking device installed on the driver’s head.

Texto completo da fonteDriving assistance systems have become more and more present over the past few years with the steady increase in traffic and the need for better road safety. These systems are designed to detect movement in the surrounding road environment in order to assist drivers as much as possible and help them make the best use of their vehicles. They focus on tactics (steering wheel, brakes, acceleration, etc. ) rather than strategy (choice of routes, etc. ). One of the main elements of this development is the 76-77 GHz ACC radar sensor. Autocruise, a firm located in Brittany, France (and more specifically on the industrial site of Technopôle Brest Iroise), develops new radar concepts with the aim of becoming one of the world leaders in the field of ACC designers. Suggesting new solutions is proving difficult without using a simulation tool which would help us grasp all aspects of this complex system. Such a tool involves implementing an efficient and reliable simulatior platform where analogue subsets and their associated signal processing have been modelled. Better control c costs (and possibly better evolution of radar functionalities) can only be achieved in the long term through mastering this modelling. This is why the available simulation tools are used jointly one with another: circuit simulations, electromagnetic simulations, 2. 5D and 3D and system simulations that give an overview of the operating ACC radar. This thesis presents a platform of this kind for the first time following the abovementioned concept of global simulation and modellinq
