  While current automotive safety standards provide implicit guidance on how
unreasonable risk can be avoided, manufacturers are required to specify risk
acceptance criteria for Automated Driving Systems (SAE Level 3 and higher).
However, the 'unreasonable' level of risk of Automated Driving Systems is not
yet concisely defined. Solely applying current safety standards to such novel
systems could potentially not be sufficient for their acceptance. As risk is
managed with implicit knowledge about safety measures in existing automotive
standards, an explicit alignment with risk acceptance criteria is challenging.
Hence, we propose an approach for an explicit representation and management of
risk, which we call the Risk Management Core. The proposal of this process
framework is based on requirements elicited from current safety standards and
is applied to the task of specifying safe behavior for an Automated Driving
System in an example scenario.
