Abstract:
Advanced vehicle navigation based on the US Global Positioning Systems (GPS) will play a major role in future vehicle control systems. Contemporary vehicle navigation systems generally consist of vehicle positioning using satellites and location and orientation of the vehicle with respect to the roadway geometry using a digitised map on a CD-ROM. The standard GPS (with Selective Availability) enables positioning with an accuracy of at least 100 m and is sufficiently accurate for most route guidance tasks. More accurate, precision navigation can be obtained by Differential GPS techniques. A new light concept called Adaptive Light Control (ALC) has been developed with the aim to improve night-time traffic safety. ALC improves the headlamp illumination by means of continuous adaptation of the headlamps according to the current driving situation and current environment. In order to ensure rapid prototyping and early testing, the step from offline to online (real-time) simulation of light distributions has been successfully completed in the driving simulator. The solutions are directly ported to real vehicles to allow further testing with natural road conditions.

Abstract:
Models of the dynamics of multibody systems generally result in a set of differential-algebraic equations (DAE). State-space methods for solving the DAE of motion are based on reduction of the DAE to ordinary differential equations (ODE), by means of local parameterizations of the constraint manifold that must be often modified during a simulation. In this paper it is shown that, for vehicle multibody systems, generalized coordinates that are dual to suspension and/or control forces in the model are independent for the entire range of motion of the system. Therefore, these additional coordinates, together with Cartesian coordinates describing the position and orientation of the chassis, form a set of globally independent coordinates. In addition to the immediate advantage of avoiding the computationally expensive redefinition of local parameterization in a state-space formulation, the existence of globally independent coordinates leads to efficient algorithms for recovery of dependent generalized coordinates. A topology based approach to identify efficient computational sequences is presented. Numerical examples with realistic vehicle handling models demonstrate the improved performance of the proposed approach, relative to the conventional Cartesian coordinate formulation, yielding real-time for vehicle simulation.

Abstract:
The work presents simulation method of dynamic properties used as assistance in the construction process of suspension systems for high-speed tracked vehicles. Special consideration has been given to the real-time coupling of virtual models with the dynamic response of actual elastic-damping elements of the vehicles. An original design method has been proposed. The method is characterized by the fact that each of the design stages are not performed sequentially, but are parallel to each other and that at each level, mutual coupling between the tasks of the design process occurs. The proposed simulation method using the dSpace system is based on the integration of virtual environment such as LMS Virtual Lab or MATLAB/Simulink with the actual object such as a damper, by means of dedicated input/output devices operating in real time. The method developed in the work allowed for an extension of the classic co-simulations, that is, simulations in two coupled virtual environments, to include an actual component or, rather – its dynamic – often non-linear – characteristic, its response to excitation. The method developed in the work allowed for an extension of the classic co-simulations, that is, simulations in two coupled virtual environments, to include an actual component or, rather – its dynamic – often non-linear – characteristic, its response to excitation.The developed test method and the computer programs have been verified by means of experimental measurements of the dynamic characteristics of the actual object during test-ground tests and in the laboratory. The obtained results of the simulations and experiments allow to confirm the validity of the assumed thesis, which has been included in the summary.

Abstract:
One of the fundamental requirements for facilitating implementation of any advanced transportation management and information system (ATMIS) is the development of a real-time traffic surveillance system able to produce reliable and accurate traffic performance measures. This study presents a new framework for anonymous vehicle tracking capable of tracing individual vehicles by the vehicle features. The core part of the proposed vehicle tracking method is a vehicle reidentification algorithm for signalized intersections based on inductive vehicle signatures. The new vehicle reidentification system consists of two major components: search space reduction and probabilistic pattern recognition. Not only real-time intersection performance but also intersection origin–destination information can be obtained as the algorithm’s basic output. A systematic simulation investigation was conducted of the performance and feasibility of anonymous vehicle tracking on signalized arterials using the Paramics simulation model. Extensive research experience with vehicle reidentification techniques on single roadway segments was the basis for investigating the performance that could be obtained from tracking individual vehicles across multiple detector stations. The findings of this study serve as a logical and necessary precursor to possible field implementation of vehicle reidentification techniques. The proposed anonymous vehicle tracking methodology with existing traffic surveillance infrastructure would be an invaluable tool for operating agencies in support of ATMIS strategies for congestion monitoring, adaptive traffic control, system evaluation, and provision of real-time traveler information.

Abstract:
The real-time traffic state estimation we propose uses a state-space model considering the variability of the fundamental diagram (FD) and sensing data. Serious congestion was caused by vehicle evacuation in many Sanriku coast cities following the great East Japan earthquake on March 11, 2011. Many of the vehicles in these congested queues were caught in the enormous tsunami after the earthquake [1]. Safe, efficient evacuation and rescue and restoration require that dynamic traffic states be monitored in real time especially in natural disasters. Variational theory (VT) based on kinematic wave theory is used for the system model, with probe vehicle and traffic detector data used to for measurement data. Our proposal agrees better with simulated benchmark traffic states than deterministic VT results do.

Abstract:
To shorten design period and reduce development costs, computer modeling & simulation is important for HEV design and development. In this paper, real-time simulation for a Series Hybrid Electric Vehicle (SHEV) is made to test its fuzzy logic control strategy based on dSPACE-DS1103 development kits. The whole real-time simulation schematic is designed and the vehicle forward-facing simulation model is set up. Driver behavior is simulated by two potentiometers and introduced into the system to realize close-loop control. A real-time monitoring interface is also developed to observe the experiment results. Experiment results show that the real-time simulation platform works well and the SHEV fuzzy logic control strategy is effective.

Abstract:
This paper presents the design and development of a fixed low-order, robustH2controller for a micro air vehicle (MAV) named Sarika-2. The controller synthesis uses strengthened discrete optimal projection equations and frequency-dependent performance index to achieve robust performance and stability. A single fixed gain low-order dynamic controller provides simultaneous stabilization, disturbance rejection, and sensor noise attenuation over the entire flight speed range of 16 m/sec to 26 m/sec. Comparative study indicates that the low-orderH2-controller achieves robust performance levels similar to that of full order controller. Subsequently, the controller is implemented on a digital signal processor-based flight computer and is validated through the real time hardware in loop simulation. The responses obtained with hardware in loop simulation compares well with those obtained from the offline simulation.

Abstract:
Software simulation is vitally important in a number of industries. It allows engineers to test new products before they leave the drawing board and enables tests that would otherwise be difficult or impossible to perform. Traditional engineering simulations use sophisticated numerical methods to produce models that are highly accurate, but computationally expensive and time-consuming to use. This accuracy is essential in the latter stages of the design process, but can make the early stages - which often involve frequent, iterative design changes - a lengthy and frustrating process. Additionally, the scope of such simulations is often limited by their complexity. An attempt has been made to produce an alternative, real-time simulation tool, developed using software and development practices from the video games industry, which are designed to simulate and render virtual environments efficiently in real-time. In particular, this tool makes use of real-time physics engines; iterative, constraint-based solver systems that use rigid body dynamics to approximate the movements and interactions of physical entities. This has enabled the near-real-time simulation of multi-vehicle trains, and is capable of producing reasonably realistic results, within an acceptably small error bound, for situations in which a real-time simulation would be used as an alternative to existing methods. This thesis presents the design, development and evaluation of this simulation tool, which is based on NVidia's PhysX Engine. The aim was to determine the suitability of a physics engine-based tool for simulating various aspects of rail dynamics. This thesis intends to demonstrate that such a tool, if configured and augmented appropriately, can produce results that approach those produced by traditional methods and is capable of simulating aspects of rail dynamics that are otherwise prohibitively expensive or beyond the capabilities of existing solutions, and may therefore be a useful supplement to the existing tolls used in the rail industry.

Abstract:
In recent years, more and more light aircraft enter our daily life, from Agricultural applications, emergency rescue, flight experiment and training to Barriers to entry, light aircraft always have their own advantages. Thus, they have become more and more popular. However, in the process of GDP research about Flight Control System design for the Flying Crane, the author read a lot of literature about Flight Control System design, then noticed that the research in Flight Control System have apparently neglected to Low-cost vehicles. So it is necessary to do some study about Flight Control System for this kind of airplane. The study will more concern the control law design for ultra-light aircraft, the author hopes that with an ‘intelligence’ Flight Control System design, this kind of aircraft could sometimes perform flying tasks according to a prearranged flight path and without a pilot. As the Piper J-3 cub is very popular and the airframe data can be obtained more easily, it was selected as an objective aircraft for the control law design. Finally, a ¼ scale Piper J-3 cub model is selected and the aerodynamics coefficients are calculated by DATCOM and AVL. Based on the forces and moments acting on the aircraft, the trim equilibrium was calculated for getting proper dynamics coefficients for the selected flight conditions. With the aircraft aerodynamics coefficients, the aircraft dynamics characteristics and flying qualities are also analyzed. The model studied in this thesis cannot answer level one flying qualities in the longitudinal axis, which is required by MIL-F- 8785C. The stability augment system is designed to improve the flying qualities of the longitudinal axis. The work for autopilot design in this thesis includes five parts. First, the whole flight profile is designed to automatically control aircraft from takeoff to landing. Second, takeoff performance and guidance law is studied. Then, landing performance and trajectory is also investigated. After that, the control law design is decoupled into longitudinal axis and later-directional axis. Finally, simulation is executed to check the performance for the auto-controller.

Abstract:
La simulation de systèmes d'énergie est un outil important pour la conception, le développement et l'évaluation de nouvelles architectures et des contrôles grille dans le concept de réseau intelligent pour les dernières décennies. Cet outil a évolué pour répondre aux questions proposées par les chercheurs et les ingénieurs dans les applications de l'industrie, et pour offrant des différentes alternatives pour couvrir plusieurs scénarios réalistes.Aujourd'hui, en raison des progrès récents dans le matériel informatique, la Simulation numérique en temps réel (DRTS) est utilisée pour concevoir des systèmes de puissance, afin de soutenir les décisions prises dans les systèmes de gestion de l'énergie automatisés (SME) et de réduire le délai de commercialisation de produits, entre des autres applications.Les simulations de réseaux électriques peuvent être classées dans les catégories suivantes: (1) la simulation analogique (2) hors simulation de ligne (3) de simulation entièrement numérique (4) la simulation rapide (5) Contrôleur Hardware-In-the-Loop (CHIL) et (6) Puissance Hardware-In-the-Loop (PHIL).Les dernière 3 sont axés sur la simulation Real-Time hardware-in-the-Loop (HIL RT-). Ces catégories portent sur les questions liées à Transitoires électromagnétiques (liste EMT), la simulation de phaseurs ou mixte (phaseur et EMT). Comme mentionné ci-dessus, ces progrès sont possibles en raison de l'évolution des architectures informatiques (matériels et logiciels); Cependant, pour le cas particulier de l'analyse des flux de puissance des réseaux de distribution (DS), il y a encore des défis à résoudre.Les architectures informatiques actuelles sont composées de plusieurs noyaux, laissant derrière lui le paradigme de la programmation séquentielle et conduisant les développeurs de systèmes numériques pour examiner des concepts comme le parallélisme, la concurrence et les événements asynchrones. D'autre part, les méthodes pour résoudre le flux de puissance dynamique des systèmes de distribution considérer le système comme un seul bloc; ainsi, ils utilisent une seule base pour l'analyse des flux de puissance, indépendamment de l'existence de plusieurs cœurs disponibles pour améliorer les performances de la simulation.Répartis dans des procédés en phase et de la séquence, ces procédés ont en caractéristiques communes telles que l'examen d'une seule matrice creuse pour décrire les DS et qu'ils peuvent résoudre simultanément une seule fréquence.Ces caractéristiques font dès les méthodes mentionné sont pas appropriées pour le traitement avec multiple noyaux. En conséquence, les architectures informatiques actuelles sont sous-utilisés, et dégrade la performance des simulateurs lors de la manipulation de grandes DS échelle, changer DS topologie et y compris les modèles avancés, entre autres des activités de la vie réelle.Pour relever ces défis Cette thèse propose une approche appelée A-Diakoptics, qui combine la puissance de Diakoptics et le modèle de l'acteur; le but est de faire toute méthode classique d'analyse de flux d'énergie appropriée pour le traitement multithread. En conséquence, la nature et la complexité du système d'alimentation peuvent être modélisées sans affecter le temps de calcul, même si plusieurs parties du système d'alimentation fonctionnent à une fréquence de base différente comme dans le cas de micro-réseaux à courant continu. Par conséquent, l'analyse des flux de charge dynamique de DS peut être effectuée pour couvrir les besoins de simulation différents tels que la simulation hors ligne, simulation rapide, CHIL et PHIL. Cette méthode est une stratégie avancée pour simuler les systèmes de distribution à grande échelle dans des conditions déséquilibrées; couvrant les besoins de base pour la mise en œuvre d'applications de réseaux intelligents
Simulation of power systems is an important tool for designing, developing and assessment of new grid architectures and controls within the smart grid concept for the last decades. This tool has evolved for answering the questions proposed by academic researchers and engineers in industry applications; providing different alternatives for covering several realistic scenarios. Nowadays, due to the recent advances in computing hardware, Digital Real-Time Simulation (DRTS) is used to design power systems, to support decisions made in automated Energy Management Systems (EMS) and to reduce the Time to Market of products, among other applications.Power system simulations can be classified in the following categories: (1) Analog simulation (2) off line simulation (3) Fully digital simulation (4) Fast simulation (5) Controller Hardware-In-the-Loop (CHIL) simulation and (6) Power Hardware-In-the-Loop (PHIL) simulation. The latest 3 are focused on Real-Time Hardware-In-the-Loop (RT-HIL) simulation. These categories cover issues related to Electromagnetic Transients (EMT), phasor simulation or mixed (phasor and EMT). As mentioned above, these advances are possible due to the evolution of computing architectures (hardware and software); however, for the particular case of power flow analysis of Distribution Systems (DS) there are still challenges to be solved.The current computing architectures are composed by several cores, leaving behind the paradigm of the sequential programing and leading the digital system developers to consider concepts such as parallelism, concurrency and asynchronous events. On the other hand, the methods for solving the dynamic power flow of distribution systems consider the system as a single block; thus they only use a single core for power flow analysis, regardless of the existence of multiple cores available for improving the simulation performance.Divided into phase and sequence frame methods, these methods have in common features such as considering a single sparse matrix for describing the DS and that they can solve a single frequency simultaneously. These features make of the mentioned methods non-suitable for multithread processing. As a consequence, current computer architectures are sub-used, affecting simulator's performance when handling large scale DS, changing DS topology and including advanced models, among others real life activities.To address these challenges this thesis proposes an approach called A-Diakoptics, which combines the power of Diakoptics and the Actor model; the aim is to make any conventional power flow analysis method suitable for multithread processing. As a result, the nature and complexity of the power system can be modeled without affecting the computing time, even if several parts of the power system operate at different base frequency as in the case of DC microgrids. Therefore, the dynamic load flow analysis of DS can be performed for covering different simulation needs such as off-line simulation, fast simulation, CHIL and PHIL. This method is an advanced strategy for simulating large-scale distribution systems in unbalanced conditions; covering the basic needs for the implementation of smart grid applications

Abstract:
Les activités de recherche ont été menées en collaboration avec l'Université de Bologne, l'Université Paris-Est et l'Université Gustave Eiffel sous la forme d'un doctorat cotutelle. Les activités sont divisées en deux macro-domaines ; les études de simulation de conduite réalisées à l'Université Gustave Eifel (IFSTTAR) et les expériences sur route organisées par l'Université de Bologne. La première partie de la recherche se concentre sur l'amélioration de la fidélité physique du simulateur de conduite à deux degrés de liberté avec une attention particulière aux signaux de mouvement et au modèle de dynamique du véhicule. Ce dernier a été développé dans MATLAB-Simulink et a la capacité de calculer en temps réel les états du véhicule et de contrôler la plateforme de mouvement. Au cours de cette phase de la recherche, des algorithmes de repères de mouvement ont été développés pour contrôler les mouvements du simulateur et l'effet des signaux de mouvement sur le comportement des conducteurs a été analysé par expérimentation. Les résultats de ces études sont discutés dans les cas d’études I et II. Dans la deuxième partie de la recherche, les performances du conducteur et le comportement visuel ont été étudiés sur la route sous différents scénarios. Le comportement visuel du conducteur a été enregistré à l'aide d'un dispositif de suivi oculaire monté sur la tête, tandis que la trajectoire du véhicule a été enregistrée avec un véhicule instrumenté équipé du système de positionnement mondial. Au cours de cette phase, plusieurs études de cas ont été développées pour surveiller le comportement des conducteurs en milieu naturaliste. La cas d'étude III vise à intégrer l'audit de sécurité routière traditionnel à un système innovant de surveillance du comportement des conducteurs. L’expérimentation sur route avec des conducteurs a été réalisée sur une artère urbaine afin d'évaluer l'approche proposée à travers des techniques innovantes de suivi des conducteurs. Ces mêmes instruments de surveillance de la conduite ont été utilisés pour évaluer l'amélioration d'un passage pour piétons au rond-point dans le cas d'étude IV. Les données de suivi oculaire ont été évaluées dans les deux études afin d'identifier un indicateur d'attention visuelle du conducteur en fonction de la position et de la durée du regard des participants. Une attention particulière est accordée à la sécurité des conducteurs vulnérables dans les zones urbaines lors de l'étude du comportement de conduite naturaliste. Le cas d'étude V a analysé le comportement de conduite du conducteur en phase d'approche d'un passage prioritaire à vélo à l'aide de mesures de sécurité de substitution. Les mesures de performance des conducteurs telles que le temps de réaction de la perception et le comportement du regard ont été utilisées pour évaluer le niveau de sécurité du passage à niveau, équipé de systèmes de signalisation standard et innovants. L’amélioration du comportement cédant du conducteur vers un passage à niveau non signalé pendant la nuit et sa réaction à un système d’alarme d’éclairage intégré ont été évaluées dans le cas d’étude VI. La dernière phase de la thèse est consacrée à l'étude du régulateur de vitesse adaptatif (ACC) avec expérimentation sur route et sur simulateur. L'expérimentation sur route a étudié l'influence du système d'aide à la conduite sur l'adaptation des conducteurs avec une évaluation objective et subjective, dans laquelle un instrument de suivi oculaire et un casque EEG ont été utilisés pour surveiller les conducteurs sur une autoroute. Les résultats sont présentés dans les cas d’études VII et VIII et l’attention visuelle des conducteurs a été réduite en raison de l’adaptation à l’ACC dans le scénario de suivi de véhicule. Les résultats de l'essai sur route ont ensuite été utilisés pour reproduire le même scénario dans le simulateur de conduite et l'adaptation du comportement des conducteurs avec l'utilisation de l'ACC a été confirmée par l'expérimentation
The related research activities were carried out in collaboration with the University of Bologna, Paris-Est University and Gustave Eiffel University (IFSTTAR) in the form of a cotutelle PhD. The activities are divided into two macro areas ; the driving simulation studies conducted in Gustave Eifel University (IFSTTAR) and on-road experiments organized by the University of Bologna. The first part of the research is focused on improving the physical fidelity of the two DOF driving simulator with particular attention to motion cueing and vehicle dynamics model. The vehicle dynamics model has been developed in MATLAB-Simulink and has the ability of real-time calculation of the vehicle states and control the motion platform. During this phase of the research, motion cueing algorithms were developed to control the simulator movements and the effect of the motion cues on drivers’ behaviour was analysed through experimentation. The results of these studies are discussed in the case studies I and II. In the second part of the research, the driver performance and visual behaviour were studied on the road under different scenarios. The driver visual behaviour was recorded with the use of a head mounted eye-tracking device, while the vehicle trajectory was registered with an instrumented vehicle equipped with Global Positioning System (GPS). During this phase, several case studies were developed to monitor drivers’ behaviour in the naturalistic environment. Case study III aims to integrate the traditional road safety auditing with an innovative driver behaviour monitoring system. The real road experiment with drivers was carried out in an urban arterial road in order to evaluate the proposed approach through innovative driver monitoring techniques. These same driving monitoring instruments were used for evaluating the improvement of a pedestrian crossing at the roundabout in case study IV. The eye-tracking data were evaluated in both studies in order to identify a driver visual attention indicator based on the participants gaze position and duration. Significant attention is given to the safety of vulnerable drivers in urban areas during the naturalistic driving behaviour study. Case study V analyzed the driver yielding behaviour in approach phase to a bicycle priority crossing with the use of surrogate safety measures. The drivers’ performance measures such as perception reaction time and gaze behaviour were used to assess the safety level of the crossing equipped with standard and innovative signalling systems. The improvement on the driver’s yielding behaviour towards an un-signalized crossing during night-time and their reaction to an integrated lighting-warning system was evaluated in the case study VI. The last phase of the thesis is dedicated to the study of Adaptive Cruise Control (ACC) with on-road and simulator experimentation. The on-road experimentation investigated the driver assistant system influence on the drivers' adaptation with objective and subjective assessment, in which an eye tracking instrument and EEG helmet were used to monitor the drivers on a highway. The results are presented in Case studies VII and VIII and drivers’s visual attention was reduced due to adaptation to the ACC in the car following scenario. The results of the on-road test were later used to reproduce to the same scenario in the driving simulator and the adaptation of drivers’ behaviour with the use of ACC was confirmed through experimentation

Abstract:
After undergoing a study about current engine modelling and mapping approaches as well as the engine modelling requirements for different applications, a major problem found to be present is the extensive and time consuming mapping procedure that every engine has to go through so that all control parameters can be derived from experimental data. To improve this, a cycle-by-cycle modelling approach has been chosen to mathematically represent reciprocating engines starting by a complete dynamics crankshaft mechanism model which forms the base of the complete engine model. This system is modelled taking into account the possibility of a piston pin offset on the mechanism. The derived Valvetrain model is capable of representing a variable valve lift and phasing Valvetrain which can be used while modelling most modern engines. A butterfly type throttle area model is derived as well as its rate of change which is believed to be a key variable for transient engine control. In addition, an approximation throttle model is formulated aiming at real-time applications. Furthermore, the engine inertia is presented as a mathematical model able to be used for any engine. A spark ignition engine simulation (SIES) framework was developed in MATLAB SIMULINK to form the base of a complete high fidelity cycle-by-cycle simulation model with its major target to provide an environment for virtual engine mapping procedures. Some experimental measurements from an actual engine are still required to parameterise the model, which is the reason an engine mapping (EngMap) framework has been developed in LabVIEW, It is shown that all the moving engine components can be represented by a single cyclic variable which can be used for flow model development.

Abstract:
This paper describes the use of video game engines as simulation environments that aid the development and testing of real-time vehicle controllers. The use of game engines for simulation is surveyed, with relevant technologies noted. The need to switch between different vehicle controllers, game engines and real vehicles gave rise to an integration architecture. The features of the architecture are described, including the execution model, message set and knowledge base. Adaptation of existing controllers, simulations and vehicles to this architecture is discussed. Issues of performance and scalability are addressed. An example is provided to illustrate the concepts.

Abstract:
Due to the increasing complexity of embedded systems and software in vehicles, the automotive industry faces an increasing need for testing and verification of components and subsystems under realistic conditions. At the same time, development cycles must be shortened for vehicle manufacturers to be competitive on the global market, and an increased amount of testing and verification must thus be performed in less time. However, simply increasing the testing volume can be prohibitively costly, meaning that testing and verification processes must be made more efficient to reduce the need for more prototypes. This paper presents a concept for distributed testing and verification of vehicles in real-time, with the aim of improving testing and verification efficiency. Through a novel combination of software tools for distributed collaborative engineering, real-time simulation, visualization, and black box simulation, the realized system makes it possible for vehicle manufacturers and their subcontractors to work more concurrently and efficiently with testing and validation. An early implementation of a system prototype is described and future development plans for the system are presented. The main software components used to build up the system are ADAMS/Car RealTime, Matlab/Simulink and a Java-based real-time visualization module originally developed for the gaming industry. A main benefit of the concept is that different disciplines involved in the product development process can use the system to enhance the concurrency between them. Control systems and mechanical engineers can view ongoing tests in real-time and change designs, and efficiently re-simulate and influence ongoing tests in a distributed manner. Through advanced visualization of simulation results and measurement data, engineers can get a clearer view of how the system or product behaves, thereby improving the quality of the validation process. The concept for distributed real-time simulation and visualization described in this paper will gather more information during the early stages of product development, and speed up the product development process due to its real-time nature. The fact that engineers can stay at their home office and only follow the test when needed will enhance their efficiency.
