The aforementioned need to relate individual test results to the remaining tests and results finds its expression in the “multi-pillar” approach put forward by GRVA (UNECE Working Party on Automated/Autonomous and Connected Vehicles) and the effort of the New Assessment/Test Method for Automated Driving (NATM) at the UNECE.
Thus, in the latest and in upcoming regulations, one can expect a more comprehensive set of requirements as compared to the past. At this point in time, the following items are discussed:
- Scenario catalog
- Simulation/virtual testing
- Track testing
- Real-world testing
- Audit/assessment
- In-service monitoring and reporting
Note that there are topics that can only be addressed by combinations of the above items. Some examples are:
- Trustworthiness (simulation/virtual testing + track testing + real-world testing)
- Qualification of tools (audit/assessment + testing + in-service monitoring)
- Coverage of hazardous scenarios (audit/assessment + scenario catalog)
- Sufficient exploration of unknown hazardous scenarios (real-world testing + in-service monitoring + scenario catalog)
It is these objectives that are in the focus of inspections by technical service providers.
