The test execution might happen in virtual, hybrid or real-world depending on the test instance allocated by the “Allocate” block. The allocated test cases form the input for this block. How the tests are carried out is not explicitly specified by the SAF and is the responsibility of the entity performing the tests. If the “Allocate” block has been executed correctly, it is guaranteed that the selected test instance is capable of performing the tests. In the case of virtual testing, the SAF recommends a harmonised approach. Therefore, a harmonised V&V simulation framework is presented in SUNRISE deliverable D4.4 (section 4.5), which can be used for virtual validation of CCAM systems but is not mandatory.
The approach consists of a so-called base layer consisting of 4 interconnected subsystems, namely the Subject Vehicle – Vehicle Dynamics, the sensors installed in the vehicle (Subject Vehicle – Sensors), the behavioural competencies of the vehicle (Subject Vehicle – AD function) and the Environment in which the vehicle operates. In this approach, the base layer is the core element that can be harmonised, because these four subsystems are essential for all simulations. That is the reason why it is possible to use standardised interfaces between these subsystems. The framework can be extended by the user in 4 dedicated dimensions related to the Target Operational Design Domain, the vehicle Sensor set-up, the Software architecture and the Hardware architecture.
