The document provides follow-up information from the SLR 77th session. SLR-77-06/Rev.1 corrects errors and omissions in Reg. 150 and will supersede GRE-94-02, potentially merged with the proposal deleting UI in R150-01 for WP.29 submission in November 2026. Four baseline documents for Stage 2/Step 2 work (SLR-77-08/Rev.1, SLR-77-09, SLR-77-10, SLR-77-07 for Regs. 48, 53, 74, 86 respectively) will be submitted to GRE-94 with presentation slides. SLR agreed to keep Par. 6.21 on conspicuity marking and to renumber paragraphs 5.5 to 5.36. Old transitional provisions are documented separately. Apparent surface definition will replace light-emitting surface. Direction indicator visibility requires further study. Harmonisation text prohibits non-mentioned lamps unless compliant with national requirements. Eleven informal documents will be submitted to GRE-94.
Proposal to amend, restructure, and clarify UN R86:
This presentation analyzes RD-ASEP model performance using test run data from Annex_9_test_runs where both left and right sound were measured. Current model shows 1.3% of measurements above L_exp; without the 2 dB margin this increases to 8.4%. Model overestimates at low speeds and underestimates at higher accelerations. Tyre rolling sound parameters have most influence on results and dominate most of the data set. Optimizing all 13 parameters reduces mean absolute error from 2.1 to 1.1 dB. More high acceleration measurements are needed to reliably calibrate the dynamic component.
AI-Enabled Road Vehicles Managing a Complex Standards Landscape presents the current landscape of standards and regulations for AI in road vehicles, structured overview of core AI governance, engineering, organisational and data governance standards required for EU AI Act conformity and UNECE compliance, and identifies gaps and challenges in alignment. ISO 8800 (2029) Road vehicles Safety of Artificial Intelligence is proposed as a common framework providing navigation and connection across horizontal AI standards with automotive sector-specific needs, reducing fragmentation and enabling transparent, traceable evidence-based assurance for regulators, industry and society while supporting compliance with EU AI Act and future UNECE requirements.
The agenda includes coordination of work referencing GRPE-92-14, GRPE-93-22/Rev.1, GRSP-78-17, and GRPE-94-06, electrical safety review, cyber security, braking, EMC, power determination and battery range, and draft text for the proposed UN Regulation. Additional meetings are scheduled for 2nd July (Hybrid, Brussels) and 9th September (Online).
Draft as revised during the first day of the 38th EVE informal group session.
