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 Task Force on Advanced Driver Assistance Systems held its 45th session on 3 March 2025 to review draft amendments to UN Regulation No. 171. Members confirmed editorial corrections to the 02 series of amendments and agreed to integrate them into a June WP.29 working document. 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.
Proposal to align the provisions on compliance with UN R10 (electromagnetic compatibility) with the wording as adopted by WP.29 for the same provisions under UN R157 (WP.29/2023/131).
