Book Description
The European research project DESERVE (DEvelopment platform for Safe and Efficient dRiVE, 2012-2015) had the aim of designing and developing a platform tool to cope with the continuously increasing complexity and the simultaneous need to reduce cost for future embedded Advanced Driver Assistance Systems (ADAS). For this purpose, the DESERVE platform profits from cross-domain software reuse, standardization of automotive software component interfaces, and easy but safety-compliant integration of heterogeneous modules. This enables the development of a new generation of ADAS applications, which challengingly combine different functions, sensors, actuators, hardware platforms, and Human Machine Interfaces (HMI). This book presents the different results of the DESERVE project concerning the ADAS development platform, test case functions, and validation and evaluation of different approaches. The reader is invited to substantiate the content of this book with the deliverables published during the DESERVE project. Technical topics discussed in this book include: Modern ADAS development platforms; Design space exploration;DRIVER MODELLING;Video-based and Radar-based ADAS functions;HMI for ADAS;Vehicle-hardware-in-the-loop validation systems

Book Description
Les accidents de véhicules automobiles sont responsables du plus grand nombre de décès dans le monde. Les chercheurs, les constructeurs automobiles et les autorités gouvernementales internationales sont continuellement à la recherche de solutions pour résoudre ce problème. La recherche a montré que la moitié des accidents peut être évitée si le conducteur est alerté d'une collision imminente une fraction de seconde à l'avance. Un mécanisme d'alerte d'un danger proche est appelé Driver Assistance Systems (DAS). Les statistiques montrent qu'une grande majorité des accidents de véhicules se passent à la suite d'une collision frontale. Minimiser les collisions frontales devrait donc diminuer considérablement les accidents de la route. Pour prévoir une collision frontale suffisamment à l'avance, l'obstacle doit être détecté à distance. En outre, pour que le système d’aide à la conduite soit réellement efficace, une collision imminente doit être prévue en tenant compte de toutes les circonstances : par exemple plus il fait mauvais, plus ce système est nécessaire. Un capteur radar remplit les conditions préalables de détection d'obstacles à longue portée en tenant compte des conditions météorologiques. Pour déterminer si un obstacle se trouve sur une trajectoire de collision avec le véhicule équipé, sa trajectoire doit être prévue avant qu'il n’arrive près du véhicule concerné. La détermination de la trajectoire d'un objet en mouvement exige que son comportement dynamique soit suivi sur une période de temps. Dans un scénario de trafic réel, plus d'un obstacle peut être considéré comme un danger, c’est pourquoi les trajectoires d'objets multiples doivent être surveillées simultanément. Un appareil capable d'assurer de telles fonctions est appelé un système de suivi d’obstacles multiples (Multiple Target Tracking : MTT). Dans cette thèse nous proposons un système d’aide à la conduite original utilisant les principes du MTT pour suivre la dynamique d’obstacles situés à plus d’une centaine de mètres et pour éviter une collision avec le véhicule équipé. En théorie, un tel système offre une des meilleures réponses au problème des accidents de la route, mais sa mise en œuvre reste difficile à réaliser. Elle implique des calculs complexes et, par conséquent, les besoins de traitement prennent du temps. Cependant, pour aviser le conducteur d'un danger imminent en temps réel, les calculs doivent être effectués très rapidement. Nous avons alors opté pour une solution optimale utilisant des processeurs afin de partager la charge de calcul et de réduire ainsi le temps de traitement. Les processeurs multiples fonctionnant en parallèle permettent non seulement d'accélérer le calcul, mais aussi d’optimiser la consommation d’énergie du système embarqué. Nous utilisons des FPGA (Field Programmable Gate Array) comme plateforme de mise en œuvre de notre système multiprocesseur. Les FPGA offrent la souplesse nécessaire pour les systèmes embarqués en constante évolution et sont très rentables. Un système multiprocesseur réalisé dans un FPGA rend son architecture flexible et reconfigurable et les processeurs peuvent être reprogrammés si nécessaire. Ainsi les systèmes multiprocesseurs à base de FPGA garantissent une souplesse du matériel ainsi que des logiciels, et par conséquent ces systèmes deviennent facilement évolutifs (scalables). Nous optimisons l'architecture du système afin de minimiser la taille du matériel tout en respectant les délais en temps réel de l’application. La minimisation du matériel ne conduit pas seulement à réduire la consommation d'énergie du système, mais nous permet aussi d'adapter le système dans un FPGA plus réduit, ce qui joue un rôle important dans la réduction du coût du système.

Book Description
An emerging trend in the automobile industry is its convergence with information technology (IT). Indeed, it has been estimated that almost 90% of new automobile technologies involve IT in some form. Smart driving technologies that improve safety as well as green fuel technologies are quite representative of the convergence between IT and automobiles. The smart driving technologies include three key elements: sensing of driving environments, detection of objects and potential hazards and the generation of driving control signals including warning signals. Although radar-based systems are primarily used for sensing the driving environments, the camera has gained importance in advanced driver assistance systems (ADAS). This book covers system-on-a-chip (SoC) designs—including both algorithms and hardware—related with image sensing and object detection by using the camera for smart driving systems. It introduces a variety of algorithms such as lens correction, super resolution, image enhancement and object detections from the images captured by low-cost vehicle camera. This is followed by implementation issues such as SoC architecture, hardware accelerator, software development environment and reliability techniques for automobile vision systems. This book is aimed for the new and practicing engineers in automotive and chip-design industries to provide some overall guidelines for the development of automotive vision systems. It will also help graduate students understand and get started for the research work in this field.

Book Description
Alexander Biedermann presents a generic hardware-based virtualization approach, which may transform an array of any off-the-shelf embedded processors into a multi-processor system with high execution dynamism. Based on this approach, he highlights concepts for the design of energy aware systems, self-healing systems as well as parallelized systems. For the latter, the novel so-called Agile Processing scheme is introduced by the author, which enables a seamless transition between sequential and parallel execution schemes. The design of such virtualizable systems is further aided by introduction of a dedicated design framework, which integrates into existing, commercial workflows. As a result, this book provides comprehensive design flows for the design of embedded multi-processor systems-on-chip.

Book Description
This thesis falls in the field of embedded real-time systems, and more precisely the in-vehicle embedded software for the evaluation of the next generation of driving assistance systems (ADAS). This document presents the three principal axes of the thesis : first, the development of a dynamic reconfigurable middleware called SCOOT-R ; second, the development of distributed real-time scheduling strategies in order to schedule SCOOT-R operations with the main goal of end-to-end QoS guarantee. Finally, the development of feedback-based scheduling schemes to schedule driving assistance systems. The adaptation in this scheme is carried out according to the current driving situation and the driver behavior, which will further lead to the change of the associated driving assistance function's criticalness.
