Proposal to clarify that the tolerance for the speed of the pedestrian dummy crossing the vehicle path is 0.4 km/h across all the series of amendments.

This document proposes amendments to UN Regulation 13 for trailers with dynamo function, superseding GRVA-22-26, GRVA-2025-15, and GRVA-21-12. The dynamo function converts vehicle kinetic energy into electrical energy without affecting braking system forces and is limited to trailers of category O₂, O₃, and O₄ pending further development. Maximum retardation power limits are 22 kW for O₃/O₄ trailers and 2 kW for O₂ trailers, measured using specified methods. Requirements include wheel locking prevention with braking rate not exceeding 0.04 per wheel, functional safety assessment per Annex 18, and demonstration that anti-lock and stability control systems comply when dynamo function is enabled. The dynamo function shall not be used during brake application testing. Administrative amendments update Annexes 2, 4, 5, 10, 19, 20, and 21 to reference e-axles and dynamo functions.

This document presents activities in China on a testing methodology for traffic rule compliance by ADS-equipped vehicles. The document addresses safety risks from inconsistent adherence to traffic regulations and proposes that ADS shall comply with traffic rules applicable to the dynamic driving task in the country of operation, applying the same rules as human drivers. It describes 12 core driving tasks categorized into safety, operation, and interaction clusters, 398 evaluation criteria, and 4 traffic elements. The methodology integrates virtual simulation, closed-site testing, and real-road testing to verify ADS compliance with traffic rules comprehensively within the operational design domain and in critical scenarios.
