Proposals for clarifications as discussed by the ADAS task force small drafting group, updated per the in-session discussions.

Proposal as submitted to WP.29 with editorial changes marked in red.

Proposal from the ADAS task force for editorial improvements and corrections to the new UN Regulation on the approval of Driver-Control Assistance Systems.

Proposal to establish uniform provisions concerning approval of vehicles of categories M₁–M₃ and N₁–N₃ with regard to Driver Control Assistance Systems (DCAS):

• Set minimum safety requirements for DCAS—driver-operated vehicle systems providing sustained lateral and longitudinal motion-control assistance while requiring driver supervision and responsibility
• Require DCAS to monitor driver engagement through hands-on and eyes-on detection, escalate warnings for disengagement, and bring the vehicle to safe stop if driver unavailability continues
• Require the system to provide information enabling driver supervision, avoid over-reliance, remain controllable, and detect system boundaries
• Address functional safety under non-fault and fault conditions, HMI design, system failures, lane positioning, manoeuvres (driver-initiated, driver-confirmed, system-initiated), speed limit compliance, and safe headway assistance
• Require validation including audit of manufacturer documentation, physical tests on track and public roads, and in-service monitoring of safety-critical occurrences
• Require software identification via R1XXSWIN
• Require manufacturers to report safety-critical occurrences and maintain annual monitoring programs

Proposal for amendments to update the draft new UN Regulation.

Proposal to retain provisions for functions meeting the definitions of ACSF-B2 and E that have not yet been developed under the proposed UN Regulation on Driver-Control Assistance Systems (DCAS).
