Aerodynamic testing and aero research challenges in Formula 1 Halle 10
Willem Toet Senior manager and professor Sauber Aerodynamics Ltd and University of Bolton SWITZERLAND
The presentation will provide a summary of how aerodynamic testing is done in Formula 1 from concept to detailed research. Wind tunnel testing had been moving toward CFD combined with full-scale, high-speed wind tunnel testing until rules put the brakes on CFD (or so it seemed) and eliminated full-scale wind tunnel work. So teams found ways to conduct effective research within these restrictions. The results are clear for all to see. For example, limiting CFD computer power has led to better software, and model tests have become races against the clock. A glimpse into the dark arts!
Innovative testbed solutions for thermal management Halle 10
Peter Drage Global business segment manager thermal testbeds AVL List GmbH AUSTRIA
Vehicle thermal management is widely accepted as one of the key development topics for future vehicle concepts, as it directly influences the vehicle range, component lifetime and passenger comfort. Huge effort goes into optimizing development processes to implement innovative solutions focusing on coupled CAE methodologies as well as interactive testing approaches. One drawback when it comes to front-loading during development is the inability to perform certain development and validation tasks on a testbed rather than in the vehicle itself. This presentation focuses on testbed solutions for thermal management applications that close the gap between virtual development and physical validation by taking into consideration the best of both worlds. These testbeds comprise highly dynamic conditioning units that are controlled via customer-specific CAE tools and thermally emulate heat sources like ICE or battery, or heat sinks such as single radiators or the entire cooling system of an engine. It will be shown how CAE models as well as virtual prototypes can be integrated in the testbed via an independent coupling platform, and how that approach is used to fulfill validation as well as control development tasks. One example is the use of a model that is implemented in a dynamic coolant conditioning unit to emulate the cooling system of a battery while the battery – including the BMS – is tested in hardware. By means of this approach it is possible to directly test the effect of adapting, for example, radiator sizes, pump power or cooling air inlets, etc to the thermal behavior of the battery.

Accurate measurement of the aerosol particle number concentration is becoming increasingly important in many areas and has been recently introduced in vehicle emission legislation. Number concentration measurements are also integrated in particle size distribution measurements. The increasing importance of aerosol metrology implies the need for traceable calibration services for particle measuring devices. METAS has developed traceable calibration methods and performance tests for particle counters, particle analyzers, dilution systems, volatile particle removers. In this presentation we will convey the basic principles of aerosol instrument calibration and report on the measurement uncertainties that can be experimentally attained.
More efficient automated HIL testing through higher test bench utilization Halle 8
Andreas Petermüller Lead engineer in-tech GmbH GERMANY
Modern HIL systems are significant investments and therefore demand the highest grade of utilization, meaning high uptime and low idle time. Yet many HIL systems can’t make efficient use of all available testing time overnight and at weekends, due to a lack of test case numbers for one specific variation of ECU hardware. By allowing the connection of a multitude of different ECU variations to one HIL at once, and enabling the remote-controlled changeover of automated testing tools, orangeSwitch offers a solution for maximizing overnight and weekend test time per HIL. Several different ECUs can be tested with one HIL during one overnight run.
Nitrogen on-site production for inertization of testing environments Halle 8
Benjamin Popp Representative INMATEC GaseTechnologie GmbH & Co KG GERMANY
Nitrogen is needed to prevent explosions when potentially hazardous appliances are being assessed. Examples include the testing of powertrains, vehicle electronics or batteries, to name a few. What is the most convenient nitrogen source available for these tests? Conventional liquid nitrogen needs to be stored in tanks or bottles, filled up and carried even when empty. The most convenient and nearest N2 source is the ambient air all around. This is what INMATEC offers: on-site nitrogen production out of compressed ambient air with customized quality and quantity.
The new reality of crash testing with M=Brake Halle 8
Philipp Hoffmann Safety testing systems expert Messring GmbH GERMANY
With over 50 years' expertise in the field of automotive safety, Messring wants to drive the future of advanced safety testing and safer mobility. That’s why the company is pushing modern technologies to make them fit for active safety. One of these developments is the M=Brake system. The main objective of the system is to simulate emergency braking before a collision in non-destructive sled tests and standard crash tests with vehicles. Testing with the M=Brake system results in more realistic test data due to the extra car pitching and dummy displacement, as in a real traffic accident.

Handling authenticated CAN messages with testing and analysis tools Halle 10
Carmelo De Mola Manager marketing K2L GmbH & Co KG GERMANY
Modern cars contain different automotive bus systems such as CAN, CAN FD and LIN, which were defined and developed before cars were connected to the internet and cloud services. As a result, most automotive bus systems have been developed without considering aspects of security such as authenticated communication. In today’s vehicles, the lack of authentication methods for communicating across automotive bus systems has made the connected car a potential target for easy hacker attacks. Car makers and Tier 1 suppliers have meanwhile recognized the importance of having authenticated communication within the car, and are supporting it in new developments to prevent unauthorized access to vehicles. This presentation will demonstrate a set of tools that simplify testing, analyzing or verifying devices that use CAN-authenticated communication.
High-quality testing: trend monitoring as a tool Halle 10
Erwin Frederiksen Test consultant automotive Moog NETHERLANDS
Test laboratories perform a wide variety of tests including static strength, dynamic performance characterization and fatigue life. With fatigue life tests, components and systems made up of different materials may degrade or wear out at different times, which then causes secondary part failures. Understanding this process, and recording information to track the changes, is necessary to document high-quality test results. The presentation will cover example test methodologies beginning with data acquisition, through to road data reproduction and tools used to run and monitor a well-documented test.

Takahiro Hara Overseas sales engineer Kyowa Electronic Instruments Co Ltd JAPAN
A printed circuit board is integrated in every kind of electronic device. In this era, 'electricity' has been a key term in the automotive industry. As the technology for electrically powered vehicles and internet-connected cars has developed, the reliability of core battery parts, and the development and assembly process for PCBs, has been a concern for automotive quality assurance. In this presentation we will show our development of a data acquisition and analysis system that is particularly useful for PCB stress and failure analysis in the assembly and development phase. By showing our specific application example, we will reveal how our product can be used for quality assurance of printed circuit boards.
Record and play back field data to validate ADAS algorithms Halle 10
Daniel Riedelbauch Automotive go-to-market manager, EMEIA National Instruments GmbH GERMANY
Although scenario simulation tools are good for virtual testing, 3D rendered scenes can be misinterpreted by algorithms designed for the real world. Record field data from ADAS sensors that can be played back in the lab to simulate driving and increase test repeatability and coverage; stream up to roughly 15GB/s of data within a single system, using RAID storage options; synchronize interfaces such as automotive networks, camera interfaces, radar, etc, down to microseconds by leveraging a modular hardware platform: ultimately, this platform allows the same system architecture to be used to play back the recorded field data to validate algorithms through HIL.
