Automobile Automation: Distributed Cognition on the Road (Transportation Human Factors)

by Victoria A. Banks Neville A. Stanton

Increasing levels of driving automation has changed the role of the driver from active operator to passive monitor. However, Systems Design has been plagued by criticism for failing to acknowledge the new role of the driver within the system network. To understand the driver's new role within an automated driving system, the theory of Distributed Cognition is adopted. This approach provides a useful framework for the investigation of allocation of function between multiple agents in the driving system. A Systems Design Framework has been developed that outlines how the Distributed Cognition paradigm can be applied to driving using both qualitative and quantitative research methodologies.

Automotive Human-Machine Interaction (Research on Automotive Intelligent Cockpit)

by Jun Ma Zaiyan Gong

This book focuses on the evaluation methodology for automotive human-machine interaction (HMI), which aim to reduce driving distractions, lower operational loads, optimize user experience design, and enhance user value.The book is divided into three parts. The first part, consisting of Chapters 1–3, introduces the evolution of automotive HMI and proposes a three-dimensional orthogonal evaluation system for automotive HMI that is comprehensive, systematic, and quantifiable. This evaluation system incorporates all evaluation items into a spatial matrix consisting of three dimensions: interaction tasks, interaction modalities, and evaluation indexes. The second part provides a comprehensive presentation and in-depth discussion of the evaluation indexes. The three rational evaluation indexes are utility, safety, and efficiency, which can be tested by the real-car driving simulator. The four emotional evaluation indexes are cognition, intelligence, value, and aesthetics. In orderto standardize the latter two subjective indexes, this book summarizes common differences in value between Chinese and European users and organizes typical aesthetic orientations in automotive UI based on art history research. The third part introduces the application of this HMI evaluation system in the automotive R&D process, including how to integrate the evaluation into a real product development process to achieve efficient product iteration.This book is suitable for intelligent cockpit and HMI designers, engineers, and researchers. It is also used as a reference for product managers and students in the field of intelligent connected vehicles.

Automotive Painting Technology: A Monozukuri-Hitozukuri Perspective

by Kimio Toda, Abraham Salazar and Kozo Saito

This book offers unique and valuable contributions to the field. It offers breadth and inclusiveness. Most existing works on automotive painting cover only a single aspect of this complex topic, such as the chemistry of paint or paint booth technology. Monozukuri and Hitozukuri are Japanese terms that can be translated as “making things” and “developing people” but their implications in Japanese are richer and more complex than this minimal translation would indicate. The Monozukuri-Hitozukuri perspective is drawn from essential principles on which the Toyota approach to problem-solving and continuous improvement is based. From this perspective, neither painting technology R&D nor painting technology use in manufacturing can be done successfully without integrating technological and human concerns involved with making and learning in the broadest sense, as the hyphen is meant to indicate. The editors provide case studies and examples -- drawn from Mr. Toda’s 33 years of experience with automotive painting at Toyota and from Dr. Saito’s 18 years experience with IR4TD, the research-for-development group he leads at the University of Kentucky -- that give details on how these two principles can be integrated for successful problem-solving and innovation in industry, in university R&D, and in the collaboration between the two. The book will bring readers up to date on progress in the field over the last decade to provide a basis for and to indicate fruitful directions in future R&D and technology innovation for automotive painting.

by Moshe R. Heller

Welcome to Bavaria - Germany - to the THIRD EUROPEAN CARS/TRUCKS SIMULATION SYMPOSIUM. That Schliersee traditional workshop-type meeting is a follow-up to the first and the second symposia which took place in May 1984 and May 1989 respectively. The objective of gathering together is to cover most of the aspects of Automotive Mathematical Modelling and Simulation in theory and practice to promote the exchange of knowledge and experience between different national and international research groups in that field, taking into consideration that every seventh German employee is related to the automotive industry. This effect is also in power at least with the traditional Detroit (U.S.A.) Automotive Industries and the growing up Japanease as well. Futhermore, there is to strenghten the international contact between developers and users of modelling and simulation techniques considering the "new world order" started in 1991 with no borders between West and East affected by the Golf-War and followed up by the "open" European Community borders of 1992. VI The traditional International Conference jointly promoted by ASIMUTH - Applied Simulation Technology and some other members of the Society of Computer Simulaton created an interest to publish new projects including their results. A large number of contributed papers has been strictly examined and selected by the editorial commitee to guarantee a high international technical standard.

Autonome Mobile Systeme 1998: 14. Fachgespräch Karlsruhe, 30. November-1. Dezember 1998 (Informatik aktuell)

by Heinz Wö Rüdiger Dillmann Dominik Henrich

Vor 13 Jahren fand im November 1985 an der Universität Karlsruhe erstmals das Fachgespräch über "Autonome Mobile Systeme" statt. Seither wird es regelmäßig jedes Jahr alternierend einmal in München, Karlsruhe und seit 1994 auch in Stuttgart abgehalten. Diese Tradition entwickelte sich insbesondere durch Forschungs­ schwerpunkte, Verbundprojekte und Sonderforschungsbereiche, die an diesen Universitäten zu dem Thema autonome Systeme bearbeitet wurden, aktuell laufen oder in Planung sind. Im Dezember 1998 findet das 14. Fachgespräch "Autonome Mobile Systeme" (AMS'98) nunmehr das siebte Mal in Karlsruhe statt. Das Fachgespräch versteht sich als kritisches wissenschaftliches Forum im deutschsprachigen Raum, auf dem Arbeiten aus Universitäten und Fachhochschulen, Forschungseinrichtungen und Firmen auf dem Gebiet der autonomen mobilen Robotersysteme vorgestellt, diskutiert und neue Ideen aufgegriffen werden. Mit Freude können die Veranstalter darauf verweisen, daß auch internationale Gäste in das Fachgespräch eingebunden werden konnten. Bei den bisherigen Fachgesprächen zeigte sich deutlich, daß sich der Begriff der Autonomie von Robotersystemen ständig ändert und von den Anforderungen der jeweiligen Anwendung geprägt wird. Zu Beginn der Fachgesprächsreihe standen autonome Fahrzeuge in industriellen Produktionsbereichen im Vordergrund. Im Jahr 1998 zeigt das Spektrum der Beiträge, daß Autonomie auch ein Grundbestandteil von Straßen-, Gelände- Wasser- und Luftfahrzeugen wird. Die Forschung auf dem Gebiet autonomer mobiler Roboter konzentriert sich zunehmend auf den Bereich Serviceroboter. So wurden auf der Hannover-Messe in diesem Jahr auf dem Gemeinschaftsstand Serviceroboter zahlreiche mobile Plattformen für Roboteranwendungen in unterschiedlichen Dienstleistungsbereichen wie Büro, Hotel, Krankenhaus und gar im privaten Umfeld vorgestellt.
