Using Kurtosion to accelerate structural life testing
Ryan Becker International sales engineer Vibration Research USA
Life testing using controlled random excitation is a long-accepted means of finding design and/or assembly flaws. Class general broadband spectra, such as the NAVMAT profile, permit testing without initially knowing the specific resonances of a new package. Now kurtosis control allows such tests to be conducted in a fraction of the time required for a Gaussian drive signal to precipitate failures. However, kurtosis control must be properly implemented to circumvent interference from the Central Limit Theorem. A unique feature within the Vibration Research Corporation (VRC) Kurtosion® process allows both resonant fatigue and simple static failure tests to be accelerated.

Covering all angles of sensor validation
Simon Thompson Business manager OXTS UK
ADAS test engineers need reliable reference data for the position, range and field of view of multiple sensors on their test vehicles. This process can often be time consuming given the number of sensor configurations on Level 3 or Level 4 vehicles. This presentation will outline a new method for validating up to 12 sensors on a test vehicle at once, each sensor having an individual range and field of view configuration. Using this method, test engineers can measure target range and visibility in real time, removing the need for complicated and expensive post-processing techniques.

Improve ADAS/AD testing using DIL with sensor fusion test
Ram Mirwani Director, global business development, ADAS Konrad Technologies USA
Guido Bairati Vice president sales VI-grade ITALY
With ADAS/AD functionality slowly but surely gaining adoption, the jury is still out on what type of testing is required and, more importantly, how much of it. With governments and focus groups working together on this topic all over the world, OEMs and Tier 1s continue to develop and test ADAS and AD functionality primarily using drive tests and miles on the road as de facto test methods. In this presentation, VI-grade and Konrad Technologies will discuss how simulators combined with sensor packages for ADAS/AD can be used together in a lab to robustly verify ADAS/AD functionality as a pre-step to ground-truthing. Driver in the loop (DIL) with sensor fusion as a test method will also include driver reaction and human perception in the test for ADAS/AD functionality with the objective of replicating real-world driving situations in a lab environment to possibly reduce costly and lengthy drive tests.
Speed up autonomous driving using big-data-based scenario simulation with vehicle in the loop
Yue Li VP technical IAE CHINA
Autonomous driving is gaining huge momentum in terms of investment and technology development. Despite the impressive progress, high-level autonomous driving (SAE L3-L5) is yet to be seen in mass production, mainly due to its technical complexity and safety implications. It is expected that high-level autonomous driving will be first seen in special applications, such as highway driving, highway transportation and robo-taxis, where either the driving environment is relatively more controlled, or the driving tasks are relatively simpler. How to validate high-level autonomous driving systems to ensure their robustness and safety remains a major challenge in the industry. Big-data-based scenario simulation with vehicle in the loop provides a promising and powerful tool in the validation and verification of high-level autonomous driving systems. Compared with traditional road testing, it is more efficient in achieving the required test mileage in a shorter timeframe, with an accurately controlled and duplicable test environment. It is also useful to test failure mode and corner cases, where road testing can be dangerous. What’s more, it gives development engineers and certification bodies insight into the full vehicle performance in a more realistic testing environment, which no other methods – such as pure virtual simulation or HIL-based systems – can achieve. It is expected that this approach will help to speed up the wide application of high-level autonomous driving systems safely and robustly.

Dynamic real-time power measurement on complex drive systems
Li Yong Manager of business development HBM and Brüel & Kjær CHINA
Power measurements are challenging when it comes to complex hybrid systems consisting of various different components such as multiple e-machines with more than three phases, gearboxes, inverters, batteries and a combustion engine. At the same time, other important signals such as temperature and vibration need to be acquired and stored as well. And all power measurements should be achievable not only at static set points to create a motor map, but also at highly dynamically changing loads such as in WLTP testing processes. The paper presents a solution to these challenges: a modular dynamic drive power analyzer.
Select the right pressure transmitter and get the benefit
Cheng Chun Huan General manager STS Sensor Technology CHINA
Most engineers use pressure transmitters in their systems, but most of them don’t know whether their choice of pressure transmitter is correct because it is only a small part of the whole system. This presentation will explain how to select the right pressure transmitter, and will answer many common questions: How to select pressure range? Is it really important for temperature compensation? Why has this output signal been suggested? Why didn’t I get the real pressure? Why did I spend time and money but could not go forward with limited pressure information?
Dynamic pressure imaging in safety testing scenarios
Terry Wason Senior business development manager XSensor CANADA
XSensor has commercialized a game-changing high-speed pressure imaging technology that allows accurate pressure imaging for applications such as rear impact whiplash, front impact seatbelt, vibration transmissibility, airbag deployment and drive-over tire contact patch analysis. Most current technologies give discrete load numbers on various points in a dummy/surface in an impact scenario, but nothing is available on what happens between these points. XSensor’s high-speed dynamic pressure imaging gives a detailed image, pressure data and pressure gradient over the entire surface. We will discuss the technology and showcase examples of dynamic pressure imaging applications.
Why you shouldn’t be using GPS-based speed measurement systems for brake testing and high-speed dynamic pressure imaging
Dr Martin Hill Director Race Technology UK
For many years companies have been using systems based solely on GPS data for carrying out brake testing and evaluation for road vehicle development. GPS-based systems were considered by many to be far superior to optical sensors or fifth-wheel setups and have been widely adopted across the industry. Certain test conditions can lead to errors of close to 1m. The SPEEDBOX INS system can eliminate them and give brake testing accuracy to as little as 2cm even under challenging test conditions. This leads to improved accuracy but also an estimate of the accuracy for every test.
A case study of fault diagnostics as applied in the R&D of hybrid powertrains
Liyong Zeng Senior sales manager Sonus Technologies CHINA
Hybrid vehicles consist of two propulsion systems - the ICE and electric motor - both operating under different conditions. The two power sources are sometimes independent and sometimes work together to propel the transmission. The hybrid powertrain is even more complex where the electric motor is integrated with the transmission. Through a case study, we will introduce the challenges in hybrid powertrain durability testing. By utilizing advanced NVH algorithms and diagnostics, we could distinguish between the various faults in the early stages. Such insights into the workings and structures give us clarity about what measures could be taken to tackle the complications.

NVH assessment and optimization for EVs and HEVs
Zhengyun Chen Application engineer Oros FRANCE
Electric and hybrid vehicle development opens a new field of noise and vibration challenges. First, a quieter cabin environment, relieved from the ICE noise, lets new sources emerge. Those sources often generate low sound levels but with unworked sound design, consequently providing a poor sound experience for passengers. On its side, the main propulsion motor plays a major role in the overall sound: its vibroacoustic behavior can be assessed and improved using the appropriate technology. Globally, E-NVH requires a wide scope of dedicated skills and high-end tools: from simulation to testing.

Acoustic signature of e-drives: correlation between vehicle tests and acoustic end-of-line quality control systems
Dr Alex Balvedi Sales manager Asia HBM and Brüel & Kjær GERMANY
Vehicle powertrain electrification will change the way we subjectively evaluate a car. In this sense, the correct understanding of its acoustic behavior is of utmost importance. Typical e-drive noise may contain modulated components. As the human brain is designed to focus on modulated signals, e-drive noise can be quite attention-grabbing. Hence, acoustic quality control and root cause analysis of e-drives in EOL (end-of-line) become critical. An acoustic EOL system must be able to flawlessly assess OK and NOK parts. This presentation gives an overview of the NVH characteristics of e-drives and how specialized EOL NVH systems are used to evaluate their acoustic quality. It will also show how vehicle tests help to define the NVH acceptance criteria in EOLs. Correlation between vehicle and EOL tests is discussed along with best practices on instrumentation and signal fetching.
Solving the validation challenge of automated driving
Zhenjiang Wang Sales manager Elektrobit CHINA
Automated vehicles must prove to be reliable in virtually every complex driving scenario. To achieve this, algorithms, functions and systems need to be validated in a range far broader than ever before. This constitutes a major challenge because of the growing complexity of more advanced systems, the need for faster development cycles, and strict legal safety requirements. Real test drive data plays a crucial role in the validation task but is not sufficient on its own. Although there is no commonly agreed number within the industry, numbers for the successful validation of a certain function or system range up to billions of high-quality test kilometers. Therefore, we introduce an approach to a comprehensive toolchain to overcome the various challenges ahead, migrating a huge part of the required test kilometers into the virtual world. Through a suitable simulation method, the number of cost-intensive test vehicles and test drives can be significantly reduced. By leveraging this approach with a cloud-computing platform, it becomes possible to easily scale to the power of thousands of high-performance computers to significantly reduce development time. The underlying platform for this toolchain covers data from real driving scenes and simulation, creating the basis to cover all required use cases for validation. Furthermore, automation is brought to data administration, enhancement and labeling, facilitating the handling of the huge number of test kilometers and petabytes of simulation data. Thanks to the cloud-based approach, test cases can be executed simultaneously around the world by different developers, scaling up to meet critical peak demands. As the overall approach is designed openly, it will be possible to create a truly comprehensive solution together with partners, answering the specific needs of car makers and suppliers.
