Following the identification of hazards and risks, a concept needs to be drafted on a functional level that defines how an ADF will react to avoid a certain hazard. This may depend on the current state of the vehicle and the ADF. The definition of a safety concept according to ISO 26262-1-12 (2018) includes:
- the required reaction to bring the vehicle to a safe state,
- the required time within which the transition needs to be achieved
- the required involvement of persons (the driver or other traffic participants),
- information about the warning strategy and / or applied degradation concepts (see Req_6).
Note that the definition of the safety concept needs to be consistent with the overall OEDR (Object and Event Detection and Response) strategy and other vehicle reactions that may be required.
Main Question:
Is there a process in place to derive safety requirements (including safety goals) to avoid unsafe malfunctioning behaviour?
