Proposal to amend para. 2.12. to replace the reference to ISO [CD] 19206-4 with ISO 19206-4:2020 and specify an adult bicyclist target, and amend para. 5.3.2. to replace the reference to ISO [CD] 19206-4:2018 with ISO 19206-4:2020, clarify requirements for demonstrating BSIS performance for smaller bicycles and smaller bicyclists differing by up to 36 per cent from nominal dimensions for the adult bicyclist target through physical testing using a child bicyclist target, simulation sufficiently validated by physical testing, or another documented means sufficiently valid and accurate to establish BSIS performance for a child bicyclist target.

Agenda for the 132nd session of the Working Party on General Safety Provisions, scheduled 28 September to 2 October. The session will address amendments to UN R107, UN R43, UN R46, UN R67, UN R110, UN R116, UN R161, UN R162, UN R163, UN R151, UN R158, UN R159, UN R166, UN R121, UN R122, UN R125, UN R0, UN R160, UN R169, UN R58, UN R105, UN R73, UN R39, and UN R58. The session will also cover vehicle automation, periodical technical inspections, driver distraction and drowsiness warning systems, and door open warning systems.

Status report on the Special Interest Group on Component & Separate Technical Unit work on UN R158 and UN R159. The SIG-C&STU is developing proposals to add Component and Separate Technical Unit approval routes to UN R151, UN R158, UN R159, and UN R166. For UN R159, Supplement 4 is under review with documents at GRSG-132. For UN R158, a Proposal for Supplement 7 is in development. The group requests feedback on structural approaches and timelines for working document submissions by January 2027.

Presentation of a method of testing for immunity of vehicles of category M₁ to electromagnetic radiation for Blind Spot Detection (BSD)/Blind Spot Information System (BSIS) as defined in the latest series of amendments to UN R151. EMC immunity test criteria for BSD are added.

Proposal to amend UN R18, UN R39, UN R46, UN R55, UN R58, UN R67, UN R73, UN R93, UN R97, UN R102, UN R105, UN R107, UN R110, UN R116, UN R121, UN R122, UN R125, UN R144, UN R147, UN R151, UN R158, UN R159, UN R160, UN R161, UN R162, UN R163, UN R166, UN R169, UN R176, UN R181, UN R182 and UN R183:

• Add new paragraphs defining Software Identification Number by reference to Consolidated Resolution on the Construction of Vehicles (R.E.3) Annex 7, para. 2,
• amend paragraphs concerning production discontinuation to clarify that production is not considered definitively discontinued if vehicle manufacturers intend to obtain subsequent extensions of approval for software updates of vehicles already registered in the market,
• add new paragraphs requiring manufacturers to provide Technical Services with information on all hardware and software having an influence on performance,
• add new paragraphs allowing vehicle manufacturers to apply for new vehicle approvals to differentiate software versions for vehicles already registered in the market from those for new vehicles,
• add new paragraphs to approval forms requesting additional information regarding software identification and software updates, including whether Software Identification Number is held on the vehicle and relevant parameters for identification of vehicles that can be updated with the represented software.

Methods for evaluating electromagnetic immunity of blind-spot detection systems are proposed using a simple reciprocating motion device equipped with a reflector. The electromagnetic immunity test is conducted after the BSD system has been activated. Vehicle’s electromagnetic immunity test methods and conditions are consistent with the previous ones. Reproducibility has been verified across various vehicle models with only minor adjustments required. The proposal seeks opinions from member countries regarding the necessity of electromagnetic immunity evaluation methods for BSD systems.

Based on GRVA-25-08, the document addresses blind spot accidents involving right-turning trucks and bicycles. It distinguishes between warning systems requiring driver reaction time and automatic brake intervention systems. The document notes that information systems with low intensity have low annoyance and low risk of deactivation, while high-intensity warnings risk driver annoyance and deactivation. It describes a specific scenario at approximately 15 km/h where a truck brakes after a turn has started with a bicycle detected at high confidence. The document indicates that next steps in safety regarding blind spot accidents should involve automatic brake intervention and suggests future discussion of UN R151 in GRVA.

Proposal to amend UN R157 for Automated Driving Systems in vehicles of categories X and Y:

• Insert new paragraphs 0.8. to 0.8.2. introducing Supplement 5 to address vehicles of categories X and Y equipped with an Automated Driving System
• Amend para. 1.1. to specify applicability to vehicles of categories N₂, N₃, M₂ and M₃
• Insert new para. 1.3. excluding vehicles of category Y and vehicles of category X without a manual mode intended to be operated on-board the vehicle
• Amend para. 2.5. to define “Ocular reference point”
• Insert new para. 2.20. to define “Safety Concept”
• Amend para. 4.5. regarding affixing of approval marks and its footnote 2
• Amend para. 5.1. to provide for automatic deactivation of BSIS in specified situations and compliance with UN Regulation No. [XXX] for vehicles equipped with an ADS
• Insert new para. 5.2.3. permitting alternative requirements for vehicles of category X with manual mode not using a driver’s seat
• Amend Annex 2 to correct the heading and modify paragraph references
• Amend Annex 4, Appendix, Table 1, footnote 1

Clarification request of the consolidated text of paragraph 6.5.10 as amended
by supplement 4

Proposal to amend UN R151 (Blind Spot Information Systems) to account for vehicles of categories X and Y equipped with an Automated Driving System. BSIS is required to work when a driver is in control; vehicles of category Y and vehicles of category X without a manual mode intended to be operated on-board the vehicle are not required to comply. Vehicles of category X with a manual mode operated on-board not using a driver’s seat may be approved using alternative requirements demonstrating equivalent safety. The proposal amends scope, definitions, and approval marking provisions. This proposal amends and supersedes ECE/TRANS/GRSG/2026/10.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R151 to ADS vehicles, including the exemption of vehicle subcategories X and Y from the requirements, and to remove the references to Unique Identifier markings.
