The purpose of this document is to provide background information on driver state monitoring (DSM) in the context of partial driving automation (SAE L2). It describes existing DSM implementations (including system interventions), the underlying design guidelines and provisions by relevant stakeholders in the field, as well as considerations on how to validate the effectiveness of driver state-related system interventions.

Moreover, the document introduces a conceptual framework for “driver readiness and intervention management” for the purpose of providing a comprehensive view of relevant aspects of driver readiness and harmonizing terms and definitions in this field. It is believed that this framework can be helpful when comparing different approaches for driver state assessment.

The document does not contain any specific technical requirements for current or future system implementations of driver state monitoring.
