The leading specialist magazine for the automotive industry features new details about research and development. Our readers are technology-oriented managers. ATZ’s reports focus on the latest R&D findings concerning every possible aspect of passenger cars and commercial vehicle engineering. Our authors are automotive experts from the industry and science. Therefore, ATZ’s reports feature individual research projects and the series development of vehicles and their components.
Cover Story – Aerodynamics
The city delivery van VW Caddy in fifth generation from Volkswagen Commercial Vehicles achieves a cD value of less than 0.30, making it the best in its class. The value was achieved primarily through the consistent use of numerical flow simulation. The air resistance has been improved by 9 % compared with the predecessor model – and this without restricting functionality and usability.
Transmissions are used in practically all automotive drive trains, both in conventional and in electrified configurations. The VKA of RWTH Aachen University and FEV have investigated whether a refined, analytical-empirical simulation approach for the transmission loss
determination already delivers good results. For more detailed investigations of hydraulic losses, a 3D CFD simulation with the MPS method has been presented.
Simulation and Test
In vehicle development today, calibration and evaluation of longitudinal dynamics is often still based on purely subjective impressions of the calibration engineers. APS technology has devised a novel, tool-supported methodology that allows objective criteria to be included in the development process.
Development – Sustainability
Almost all plastics used in the automotive industry are derived from petroleum. By analyzing the life cycle of the products used, Seat is already gaining important information on how to contribute to a more sustainable future through the use of biomaterials, for example rice husks made from the Oryzite material.
Research – Assistance Systems
Compared to conventional charging, inductive charging offers the convenience of not having to physically connect the electric vehicle with a so-called wall box. To also relieve the driver of the fine passenger car positioning required, an automated positioning system was developed in a research project at the University of Stuttgart. The electric vehicle is precisely positioned on the charging coil. In contrast to comparable systems, this one also grants a higher positioning radius depending on the coil size.
