Scenario-based verification and validation (V&V) has emerged as the predominant approach for the performance evaluation of automated driving systems (ADSs). Many scenario-generation methods have been proposed to search for critical scenarios, i.e. disengagement or traffic rule violations. However, the widely adopted binary (pass/fail) criterion suffers from two main limitations, i.e., the difficulty of locating root causes and the lack of statistical guarantee of testing sufficiency. Recently, new scenario engineering approaches focusing on the intelligence of ADSs enlightened a promising pathway via dynamic driving task decomposition and function atom constraints. However, none of the state-of-the-art scenario description languages support such approaches. To fill this gap and facilitate further research into this promising direction, in this work, we propose a generic architecture to extend the existing scenario description languages for the intelligence testing of ADSs. The case study with WMG SDL demonstrates the capability and flexibility of the proposed extension design in defining intelligence function constraints.
