This book uses automotive embedded systems as an example to introduce functional safety assurance and safety-aware cost optimization. The book explores functional safety assurance from the perspectives of verification, enhancement, and validation. The functional safety assurance methods implement a safe and efficient assurance system that integrates safety verification, enhancement, and validation. The assurance methods offered in this book could provide a reasonable and scientific theoretical basis for the subsequent formulation of automotive functional safety standards. The safety-aware cost optimization methods divide cost types according to the essential differences of various costs in system design and establish reasonable models based on different costs. The cost optimization methods provided in this book could give appropriate cost optimization solutions for the cost-sensitive automotive industry, thereby achieving effective cost management and control. Functional safety assurance methods and safety-aware cost optimization support each other and jointly build the architecture of functional safety design methodologies for automotive embedded systems. The work aspires to provide a relevant reference for students, researchers, engineers, and professionals working in this area or those interested in hardware cost optimization and development cost optimization design methods based on ensuring functional safety in general.

Many important industrial applications incline toward better understanding of the constitutive properties of matter. Nowadays, the development of measurement possibilities, even in nanoscale, allows for multiscale formulations that drive to the more sophisticated models used in continuum mechanics. These phenomenological models are particularly important and useful for solutions of very concrete initial boundary value problems. Our interests are focused mainly on detailed descriptions of material behavior that depend not only on simple stress-strain relationships but also includes the strong influence of loading type, which introduces temperature, strain rate dependence, fracture, etc. Understanding these physics phenomena is of fundamental importance for successful and responsible computations. In particular, using the popular commercial programs requires deep understanding of constitutive formulations and their restrictions. These lectures are addressed to industrial users who are responsible for making crucial decisions in design, as well as, to young scientists who work on new models that describe the behavior of materials which also account the new influences and reflect the complexity of the material behavior. At the end, let me express my gratitude to the lecturers of the CISM course No. 328 on "Advances in Constitutive Relations Applied in Computer Codes", held in Udine in July 2007, who finally prepared the included materials. Unfortunately, during the preparation and collecting papers for this book, our friend and colleague Prof. Janusz R. Klepaczko passed away. This is a very big loss for the society of mechanics.

Since 1995 the annual international forum on Advanced Microsystems for Automotive Applications (AMAA) has been held in Berlin. The event offers a unique opportunity for microsystems component developers, system suppliers and car manufacturers to show and to discuss competing technological approaches of microsystems based solutions in vehicles.

The book accompanying the event has demonstrated to be an efficient instrument for the diffusion of new concepts and technology results. The present volume including the papers of the AMAA 2005 gives an overview on the state-of-the-art and outlines imminent and mid-term R&D perspectives. The 2005 publication reflects - as in the past - the current state of discussions within industry. More than the previous publications, the AMAA 2005 "goes back" to the technological requirements and indispensable developments for fulfilling the market needs. The large part of contributions dealing with sensors as well as "sensor technologies and data fusion" is exemplary for this tendency.

In this context a paradigm shift can be stated. In the past the development focused predominantly on the detection and processing of single parameters originating from single sensors. Today, the challenge increasingly consists in getting information of complex situations with a series of variables from different sensors and in evaluating this information. Smart integrated devices using the information deriving from the various sensor sources will be able to describe and assess a traffic situation or behaviour much faster and more reliable than a human being might be able to do.

Human-Machine Interaction for Automated Vehicles: Driver Status Monitoring and the Takeover Process explains how to design an intelligent human-machine interface by characterising driver behaviour before and during the take-over process. Multiple solutions are presented to accommodate different sensing technologies, driving environments, and driving styles. Depending on the availability and location of the camera, the recognition of driving and non-driving tasks can be based on eye gaze, head movement, hand gesture, or a combination of them, and this book addresses all possibilities.Technical solutions to recognise drivers' various behaviours in adaptive automated driving are described with associated implications to the driving quality. Cutting edge insights to improve the human-machine-interface design for safety and driving efficiency are also provided, based on the use of this sensing capability to measure drivers' cognition capability.

The new edition of High-Conformal Gearing continues to address the kinematics and the geometry of conformal (Novikov) gearing and high-conformal gearing. The book deals with gears that feature convex-to-concave contact of the tooth flanks of a gear and a mating pinion. Gears of this type are commonly referred to as conformal gearings. Novikov gearing is the most widely known example of conformal gearing. The helical gearing by Wildhaber, Bramley-Moore (otherwise known as the Vivkers, Bostock, and Bramley gearing, or just V.B.B.-gearing), are well-known designs of gearing that are loosely referred to as conformal gearing. The principal differences between conformal gearing as well as high-conformal gearing and Wildhaber helical gearing are outlined. It also shows that Wildhaber helical gearing from one side, and Novikov gearing from another side, are two completely different gear systems that cannot be combined into a common gear system. This book aids mechanical, automotive, and robotics engineers specializing in gear design with successfully transmitting a rotation. It also serves as a resource for graduate students taking advanced courses in gear design.

This book comprises the proceedings of the conference “Future Automotive Production 2022�, which took place in Wolfsburg. The conference focused on hybrid lightweight design, which is characterized by the combination of different materials with the aim of improving properties and reducing weight. In particular, production technologies for hybrid lightweight design were discussed, new evaluation methods for the ecological assessment of hybrid components were presented and future-oriented approaches motivated by nature for the development of components, assemblies and systems were introduced. Lightweight design is a key technology for the development of sustainable and resource-efficient mobility concepts. Vehicle manufacturers operate in an area of conflict between customer requirements, competition and legislation. Material hybrid structures, which combine the advantages of different materials, have a high potential for reducing weight, while simultaneously expanding component functionality. The future, efficient use of function-integrated hybrid structures in vehicle design requires innovations and constant developments in vehicle and production technology. There is a great demand, especially with regard to new methods and technologies, for "affordable" lightweight construction in large-scale production, taking into account the increasing requirements with regard to variant diversity, safety and quality.

Transport is responsible for a growing share of global energy consumption and greenhouse gas emissions, emerging as an economic sector for which technical solutions have shown limited benefits and a shift to electric mobility is seen as an essential part of tackling both problems. However, despite electric motive power being older technology than internal combustion engines and having many advantages, both inherent disadvantages and the inertia of not being the dominant road transport technology mean that it is only recently that electric vehicles (EVs) have attracted serious policy attention. Electrifying Mobility: Realising a Sustainable Future for the Car examines the basis of this electric mobility 'turn', considering the drivers, barriers to adoption and the current lived experience of EV use, drawing upon this experience to inform planning for mass EV adoption and how regulation might change to reflect the specific needs and challenges raised. Considering future transport policy, practice, and management where EVs become an important part of the road transport fleet, and, it is assumed, eventually come to dominate it, chapters study how EV and Connected and Autonomous Vehicle (CAV) technologies relate, and whether there are synergies with shared mobility. The Transport and Sustainability series addresses the important nexus between transport and sustainability containing volumes dealing with a wide range of issues relating to transport, its impact in economic, social, and environmental spheres, and its interaction with other policy sectors.
