Proceedings 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 knowledge 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 SpringerLink and Springer für Professionals) 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.

In addition, chassis development is focusing on enhancing ride comfort while also improving NVH characteristics. At the same time, modularization strategies, concepts for the electrification of the powertrain, and steps towards greater system connectivity are making increasingly complex demands on the chassis and its development. Developers are being called upon to respond to these challenges with a variety of solutions. On 24 and 25 June 2014, chassis.tech plus will bring together experts in the field of the chassis, steering systems, brakes, and wheels / tires for an exchange of ideas and experience and constructive discussions on the latest topics. On behalf of the Scientific Advisory Board, we cordially invite you to attend the 5th International Munich Chassis Symposium, the largest event of its kind in the world. Renowned keynote speakers will give a valuable overview of challenges and solutions for the chassis of the future. In the well-established manner, four parallel sections will specifically address issues relating to the chassis, steering systems, brakes, and wheels / tires. The program will be rounded off by a plenary section on future chassis development and driver assistance systems as well as automated driving. We look forward to welcoming you at the Hotel Bayerischer Hof in the heart of Munich and wish you a pleasant journey and interesting and exciting days at the International Chassis Symposium.
