Correction to the summary description: “It is based on ECE/TRANS/WP.29/GRSG/2023/18”.

Proposal to address cross-referencing issues in UN Regulation No. 79 with respect to UN Regulation No. 130 (Lane Departure Warning System), especially with regard to Australian lane marking specifications and to incorporate amendments addressing ACSF systems relative to the new UN Regulation on driver control assistance systems (DCAS).

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 to differentiate between the scope of UN R79 and the proposed UN Regulation on Driver Control Assistance Systems (DCAS).

Updated to note cancellation of GRPE May 2024 session and addition of brief GRVA June session to formalise outcomes of its May session in the USA.
