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
