Proceedings Ein Stetig Steigender Fundus an Informationen Ist Heute Notwendig, Um Die Immer Komplexer Werdende Technik Heutiger Kraftfahrzeuge Zu Verstehen

Proceedings Ein stetig steigender Fundus an Informationen ist heute notwendig, um die immer komplexer werdende Technik heutiger Kraftfahrzeuge zu verstehen. Funktio- nen, Arbeitsweise, Komponenten und Systeme entwickeln sich rasant. In immer schnelleren Zyklen verbreitet sich aktuelles Wissen gerade aus Konferenzen, Tagungen und Symposien in die Fachwelt. Den raschen Zugriff auf diese Infor- mationen bietet diese Reihe Proceedings, die sich zur Aufgabe gestellt hat, das zum Verständnis topaktueller Technik rund um das Automobil erforderliche spe- zielle Wissen in der Systematik aus Konferenzen und Tagungen zusammen zu stellen und als Buch in Springer.com wie auch elektronisch in Springer Link und Springer Professional bereit zu stellen. Die Reihe wendet sich an Fahrzeug- und Motoreningenieure sowie Studierende, die aktuelles Fachwissen im Zusammen- hang mit Fragestellungen ihres Arbeitsfeldes suchen. Professoren und Dozenten an Universitäten und Hochschulen mit Schwerpunkt Kraftfahrzeug- und Moto- rentechnik finden hier die Zusammenstellung von Veranstaltungen, die sie selber nicht besuchen konnten. Gutachtern, Forschern und Entwicklungsingenieuren in der Automobil- und Zulieferindustrie sowie Dienstleistern können die Procee- dings wertvolle Antworten auf topaktuelle Fragen geben.

Today, a steadily growing store of information is called for in order to understand the increasingly complex technologies used in modern automobiles. Functions, modes of operation, components and systems are rapidly evolving, while at the same time the latest expertise is disseminated directly from conferences, congresses and symposia to the professional world in ever-faster cycles. This series of proceedings offers rapid access to this information, gathering the specific know- ledge needed to keep up with cutting-edge advances in automotive technologies, employing the same systematic approach used at conferences and congresses and presenting it in print (available at Springer.com) and electronic (at Springer Link and Springer Professional) formats. The series addresses the needs of automotive engineers, motor design engineers and students looking for the latest expertise in connection with key questions in their field, while professors and instructors working in the areas of automotive and motor design engineering will also find summaries of industry events they weren’t able to attend. The proceedings also offer valuable answers to the topical questions that concern assessors, researchers and developmental engineers in the automotive and supplier industry, as well as service providers.

WELCOME IN STUTTGART In March 2019, the Research Institute of Automotive Engineering and Vehicle Engines Stuttgart (FKFS) invites you to the 19th Stuttgart International Symposium »Automo- tive and Engine Technology«. I heartily welcome all participants to two fascinating congress days, dealing with nothing less than the future of our mobility. I am therefore delighted to be the patron of this event once again this year. FKFS has been demonstrating for decades that it is a reliable partner in many areas. The local automotive industry profits from a highly-regarded research institute in close proximity. Thanks to the cooperation with Stuttgart University, students are able to gain access to the regional automotive sector. As a hotbed of specialists and experts, FKFS provides a valuable source of young engineers who help keep Baden-Wuerttemberg one of the leading automotive locations in the world. The state government holds FKFS in high esteem as a long-term cooperation partner. This is underlined, for example, by the wind tunnels the State of Baden-Wuerttemberg set up at Stuttgart University, which FKFS still operates for the University today. In the »Baden-Wuerttemberg Automotive Industry Strategic Dialog« (which was also set up by the state government), FKFS has a permanent role in collaborative work on a concept for the future. The clock is ticking for new mobility solutions. Climate targets are looming ever closer and it is only possible to fulfill them with new, cleaner drive technologies. This is a huge challenge. However, we must not regard it as a burden, but as an opportunity we must take in order to actively shape the mobility of the future. Because those shaping the technology will remain the global leaders in it. Therefore, it is one of the state government’s key tasks to guide the car manufacturing state Baden-Wuerttemberg into a future which is both environmentally-friendly and successful. To achieve this, inter- linking science, politics, business and civic society is essential. With this year’s Symposium motto, »The transformation of the automotive industry«, FKFS is tackling the central challenges for the future of the automotive industry head- on. At the same time, it forms an important platform to bring various stakeholders to- gether and enter intensive specialist discussions. I thank FKFS and all the participating companies for organizing and implementing the Symposium. I wish the participants interesting lectures, exciting discussions and new inspiration.

Winfried Kretschmann Prime Minister of the State of Baden-Wuerttemberg

A WARM WELCOME

The transformation of the automotive industry

The automotive industry is currently undergoing enormous and rapid changes. Demands upon research and development are constantly increasing, and new fields of research are arising as well. Both manufacturers and suppliers are developing new business models in order to remain competitive. The European Environment Ministers’ target to reduce vehicle CO2 emissions by a total of 35 per cent by 2030 (compared with the year 2020) highlights the necessity and urgency of a technological shift. Most discussions regarding potential solutions concern the electrification of drives, but the use of renewable fuels (or synthetic fuels) is also on the agenda. More than a year ago, the State of Baden-Wuerttemberg set up the »Automotive Industry Strategic Dialog«. This alliance of politics, business, science, trade unions, consumer organizations, environmental organizations and civic society is pursuing a holistic approach, tapping into innovation potential beyond traditional industry sector limits and aiming to drive the automotive industry in Baden-Wuerttemberg forward successfully. Drives and emissions, autonomous driving and networking, disruptive vehicle architectures, driving dynamics control systems and thermal management: the automotive industry has plenty to talk about. Experts from science and industry will be discussing these topics and many more at the 19th Stuttgart International Symposium »Automotive and Engine Technology« from 19 – 20 March 2019 at the Haus der Wirtschaft. The latest technology, future concepts and new research results will be presented in sessions running in six parallel strands, with more than a hundred lectures. There will be a podium discussion on the topic »The transformation of the automotive industry«, with prominent participants. We have also been able to attract very high- profile speakers for our plenary lectures. There will be many opportunities for exchanging ideas; not only during the breaks and at the trade exhibition, but at the special evening event too. We look forward to welcoming you to Stuttgart – the birthplace of the automobile – and wish you two highly-interesting days at the 19th Stuttgart International Symposium!
