Proposal to delete the draft “Reserved” paragraph 5.3.7.2.4.3. in GRVA/2026/18. Reserving paragraph 5.3.7.2.4.3. in the 01 series would mean that the subsequent paragraphs would be out of line with the numbering in the 02 series, making future amendments to UN R171 unnecessarily challenging.
Proposal to delete paragraph 1.2.6. excluding e-axle trailers with e-axles providing electric propulsion and/or incorporating an electric regenerative braking system from the scope of UN R13, and add definitions of “e-axle,” “e-axle trailer,” “dynamo function,” and “e-trailer”; add special requirements for power-driven vehicles supporting e-trailer operation, e-axle trailers equipped with dynamo function, and e-trailers of category O; add requirements for electric control lines conforming to ISO 11992-2:2027; specify message support and functional compatibility; and add provisions for electric regenerative braking, dynamo function, and propulsion, including parameters such as retarder torque demand priority, propulsion force limits, overriding mode activation at speeds below 15km/h, and vehicle stability function interaction.
Proposal to amend para. 3.5.1. of Annex 4 to require the manufacturer to demonstrate to the approval authority that effective processes, methodologies and tools are in place, up to date and being followed within the organization to manage the safety and continued compliance throughout the product lifecycle, and to demonstrate to the approval authority at least every three years that the safety management system continues to comply with these requirements.
In January 2022, an M1 passenger vehicle with a detached tyre caused its Anti-lock Braking System to activate, preventing effective braking and resulting in collision with a stationary lorry. The coroner concluded the ABS functioned as intended but created an unsafe scenario by using the fastest rotating wheel as reference speed, and recommended changes to prevent future deaths. The UK proposal to amend UN R13-H would require manufacturers to affirm that strategies to achieve system objectives will not prejudice safe operation of systems under non-fault conditions, including failures of other systems involved in achieving system function such as tyres or wheels, and that documentation be supported by analysis showing how the system will behave upon any fault with bearing on vehicle control, performance, or safety, including faults with other systems involved in achieving system function.
OICA-CLEPA-EME comments on German proposal GRVA-25-07 to require the approval authority granting UN R155 or UN R156 type approvals to use CSMS or SUMS certificates signed by the same approval authority. OICA-CLEPA-EME identify that CSMS and SUMS are Management Systems covering entire manufacturer organizations, and mandating the same approval authority for Management Systems certificates and approvals will have significant consequences for original equipment manufacturers typically using multiple approval authorities in homologation. The submission proposes keeping text unchanged to allow different approval authorities for Management Systems certificates and type approval based on voluntary acceptance, implementing wording on information exchange if different approval authorities are involved, and establishing a horizontal approach for Management Systems with mutual recognition aspects considered.
Proposal to amend para. 5.3.3.2. to correct a referencing error by replacing the reference to para. 5.1.4. with a reference to para. 5.3.1.1., which directly relates to mechanical parts of the steering transmission, thereby removing possible uncertainty or the need to liaise with the designated technical service or approval authority to confirm interpretation of the current text.
Proposal to develop UN GTR for both assisted and automated parking. The document presents parking product classifications in China, including assisted parking (park-in/park-out, cruising capability, remote-control variants) and automated parking systems. Current UN Regulations lack specific technical requirements, test methods, and test scenarios for parking functions. China is developing national standards GB for parking combined driver assistance systems and automated parking systems, with approval expected by end of 2026 and early 2027 respectively. The proposal suggests establishing a Task Force to study applicability of current UN Regulations to parking products, then determining whether to establish an IWG or formulate new regulations.
