Triggering events represent specific conditions of a driving scenario that serve to initiate a subsequent system reaction, possibly leading to a hazardous event. The analysis of triggering events could help to identify the system weaknesses (related to sensors, algorithms and actuators) and related scenarios that could result in an identified hazard. Identified events shall be addressed by functional improvements of the ADF to respond appropriately and correctly. Functional improvements could incorporate several aspects, for instance sufficient performance of sensors, sufficient performance of detection and decision algorithms, as well as appropriate HVI regarding the controllability of the vehicle and avoidance of misuse, etc. (ISO 21448 (2022)).
Main Question:
Have improvements to the functional and system specifications been identified to avoid or mitigate SOTIF related risks?
Sub-Questions:
- Are there triggering events related to sensors, algorithms and actuators identified?
- Is there an assessment of whether the system appropriately responds to triggering events?
