Cover Stories

• End-user Acceptance of Anti-glare Glasses

  According to a survey conducted in France and Germany, the situation that causes the most stress to car drivers is the glare from the headlamps of oncoming vehicles. In this article, Valeo discusses the benefits and customer acceptance of Les Lunettes, a solution to reduce glare with adjustable closures.

• Thomas Form, Volkswagen

  In the ATZ interview, Professor Thomas Form, Head of the Electronics and Vehicle Research Field at Volkswagen AG, talks about how a realistic view of assistance functions for autonomous driving can be made possible.

• VR Environment for the Development of a Backend-based ACC System

  Assistance systems have to be tested extensively. In an interdisciplinary project, Bertrandt creates a connection between ADAS and IT connectivity to the backend for further development of an adaptive cruise control system. Extended ACC functionalities and network quality can be intensively evaluated in a VR driving simulator.

• Jiggles Joining of Vehicle Frames

  In vehicle frame construction, flexible production systems with low investment costs are required due to the increasing number of variants and falling specific quantities. The chair of Production Engineering of E-Mobility Components at the RWTH Aachen University refined the concept of part-integrated fixture functions to join complex assemblies by using a snap-fit instead of specific jigs.

• Systems Engineering Enabled by Virtual Prototypes

  Due to the progressive networking of modern vehicle systems, the development departments of original equipment manufacturers and suppliers are increasingly facing new challenges. In practical application, the use of virtual prototypes enabled IPG to reduce the number of real prototypes by up to 30 %.

• Functionally Secure IT Backend for Automated Driving

  The inclusion of a functionally safe IT backend will contribute to cost-effective, safe and speedy automated driving. ESG Elektroniksystem- und -Logistik-GmbH uses solutions for aviation or railroad technology, as solutions in the automotive industry according to ISO 26262 are not safe enough.

• Cyber Intrusion Detection and Prevention as a Learning System

  What do the US Congress and automotive Ethernet have in common? They have both made it unavoidable to think about detection and prevention by hacker intrusions. Soon-to-come legal requirements for automated driving and the increasing connectivity of vehicles call for an Intrusion Detection and Prevention System (IDPS). Here, Escrypt allows embedded security components and analytical tools to interact intelligently with backend services.

• Potentials of a Predictive Powertrain Management

  The required technologies like connectivity, driver assistance systems and different degrees of electrified powertrains are evolving faster than ever. The optimization potentials are way beyond the predicted years ago. These three key technologies will be in the focus of this AVL article.

• Benchmark Parameters of Transmissions

  The electrification of the powertrain has led to a wide variety of transmission concepts. In order to identify energetically optimal transmission concepts, an objective comparison of different transmissions is necessary. However, this is difficult because the energetic potential of a transmission can only be evaluated in conjunction with the connected energy converters. As a consequence, parameters were developed at the Institute of Automotive Engineering of the Technical University of Braunschweig which quantify the consumption-related properties of a considered transmission and indicate the potential for reducing consumption separately for the transmission.

• Developing Vehicle Functions by Means of Rapid Control Prototyping

  In the case of rapid control prototyping, simulations as well as real test bench trials with the same dynamic characteristics are used for functional development. At the University of Kassel, it was examined how rapid test prototyping can reduce test bench time while at the same time providing an improved understanding of the system. Due to the simulation environment, the system behavior can be analyzed comprehensively, tested efficiently, and ultimately validated on the test bed in this model-based function development process.
