What is the role of scenario-based testing in ensuring the safety and reliability of ADAS technology?

Scenario-based testing plays a vital role in the development of AD/ADAS systems. By simulating real-world conditions to test various critical scenarios in a controlled environment it helps ensure safety and reliability. This comprehensive scenario-based testing approach helps to create robust and trustworthy ADAS technology. With more and more new regulations being introduced, increased testing efforts with specific capabilities are required to thoroughly test ADAS technology.
 
TÜV SÜD is well prepared for the increased complexity of technology in future vehicles and can also provide various driving robots with the required specialists. Our team of experts has gained extensive experience in scenario-based testing from global projects such as PEGASUS, V&V Methods and ATLAS  L4. We are familiar with all the methodologies and latest regulations for implementing scenario-based testing methods applicable to the latest automotive and ADAS technologies.

Why scenario-based testing for ADAS is important

Whether you are developing vehicles with AV functions; integrating your camera, LIDAR or radar-based platform, or need to verify your sensor models, autonomous vehicle testing in a real-world environment is necessary.

Scenario-based ADAS testing enables a comprehensive system performance evaluation across a wide range of real-world driving conditions and scenarios in a controlled environment. This helps to identify and address potential safety and functionality issues early in the development process that may not be apparent in standard test environments. By considering existing and upcoming standards and regulations for international homologation and type approval of SAE L2+ to L5 like DCAS (Driver Controlled Assistance Systems), you gain a competitive edge by staying ahead of the curve and ensuring quick market access.

Not only does scenario-based testing enhance ADAS technology the safety, but it also helps to develop more robust and efficient autonomous driving technologies. Consequently, it instils end-user trust and acceptance that self-driving cars are safe to use on public roads.

What a comprehensive scenario-based test for ADAS involves

Scenario-based testing is complex as it requires a safe, synchronised, and controlled proving ground test environment. Tests simulate diverse situations to ensure that ADAS can handle various driving conditions. 

Testing scenarios are executed multiple times to collect comprehensive test data. This includes sensor inputs and video footage, which enable performance metrics like obstacle detection and reaction times to be evaluated.

The autonomous vehicle testing toolchain must be at the same technological level as the AV functions to ensure consistent results. This requires an AV test regime like TÜV SÜD’s that is smart, efficient, reliable, repeatable, accurate, and precise. 

During scenario-based testing, multiple dynamic objects in a precisely controlled and repeatable testing environment are used. All dynamic and static objects are connected by a low latency data connection. This includes the autonomous vehicle under test and surrounding vehicles that represent the criticality of a defined scenario. As AV functions might display non-deterministic behaviour, the surrounding vehicles must be able to dynamically adjust their trajectory according to the applied strategy of the vehicle under test.

As your autonomous vehicle testing partner TÜV SÜD ensures your AV technologies are thoroughly tested and proven.

How comprehensive are the test scenarios in covering various real-world driving conditions and potential hazards?
TÜV SÜD’s test scenarios for ADAS cover a wide range of real-world driving conditions and potential hazards to reliably assist drivers in any situation. This includes urban environments, highways and rural roads. Test also cover differing weather conditions, night driving, various obstacles, and multiple road surfaces and. Other unpredictable scenarios, such pedestrians crossing and inconsistent driver behaviour, test the system's ability to cope with less common driving situations.
How can physical road testing be effectively integrated with virtual and simulation-based testing methods?
A hybrid testing approach combines the strengths of both physical and virtual environments. This maximises what tests cover and reduces development time and costs. Virtual simulations are particularly useful for situations that are difficult or impossible to replicate. These provide valuable insights that can be validated using physical road testing. Virtual tests allow physical tests to focus on critical scenarios and verify real-world conditions performance. Combining both virtual and physical methods enables TÜV SÜD to optimise testing efficiency so that you can enhance ADAS safety and reliability before
What are the regulatory hurdles and requirements for ADAS testing on public roads?
Although regulations vary by country, they will normally include safety protocols. This includes pre-testing in controlled environments, risk assessments, and public road testing permits. It is the responsibility of the manufacturer to demonstrate that their ADAS technology complies with required safety standards and is able to cope with real-world scenarios. Continuous monitoring and test results reporting to regulatory bodies, data privacy laws compliance, and ensuring that incidents are quickly addressed are also required. To ensure the ADAS is safe and reliable for public use, this requires collaboration with regulatory authorities in each country, as well as detailed documentation and a robust testing framework.
