Proposal to modify provisions for system boundaries, driver disengagement detection, manoeuvre initiation, and risk mitigation functions. Changes include clarifications on visual engagement assessment, headway configuration warnings, and driver unavailability response procedures. Amendments address system behaviour at boundary conditions, lane change manoeuvre protocols, and documentation requirements. Test procedures are updated regarding bicycle target positioning and terminology. Manufacturing processes for safety management during vehicle operation are added. Documentation definitions and simulation model criticality assessments are clarified.

Proposal to establish a Supplement to the 01 series of amendments to UN Regulation No. 171 on Driver Control Assistance Systems. The amendments modify technical requirements for system boundaries, driver disengagement detection, manoeuvre initiation, and driver unavailability response. New definitions for “Target Lane” and “Highway-like road” are introduced. Changes address system behaviour at boundary conditions, visual engagement criteria, and hands-off request withholding on highway-like roads. Testing and documentation requirements are revised to clarify Type Approval Authority responsibilities and manufacturer safety management processes during the operation phase.

The ADAS task force reviewed draft amendments to UN Regulation No. 171. The task force agreed on editorial corrections to the 02 series of amendments for a formal submission to the June WP.29 session. CLEPA submitted three clarification proposals for the 02 series to be addressed via supplement if needed. Draft supplements to the original version and 01 series were introduced for GRVA consideration. The TF agreed to take a break before initiating Phase 4 development work and invited stakeholders to submit written proposals on future developments.
