Proposal to amend UN R13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178 by introducing provisions on software identification and software updates. Amendments add new paragraphs referring to Software Identification Number definitions in Consolidated Resolution R.E.3, require manufacturers to provide Technical Services with information on hardware and software influencing performance, permit vehicle manufacturers to apply for new approvals differentiating software versions for registered versus new vehicles while avoiding test duplication, and modify production discontinuation provisions to exclude cases where manufacturers seek approval extensions for software updates of registered vehicles.
UN R48 baseline text for a 10 series of amendments proposes uniform provisions for vehicle lighting and light-signalling device installation approval. The document consolidates modifications agreed at working group session through dated amendment documents and resolutions. Pending issues include determining “[any] subsequent series” terminology for frozen regulations, renumbering and cross-checking paragraphs, addressing apparent surface visibility, improving daytime running lamp visibility against stop lamps, resolving “prohibited if not allowed” language, and numbering all figures with titles. Editorial polishing includes standardizing hyphenated terminology (“driving-beam,” “passing-beam,” “retro-reflector,” “direction-indicator lamp”), applying consistent UN Regulation references, replacing “communication sheet” with “communication form,” assigning table and figure numbers consistent with similar regulations, and correcting percentage notation to “per cent.”
GTB proposes simplifying UN R48 by developing a single CAD-based method to determine apparent surface at early design stages. The proposal deletes the “light-emitting surface” definition and establishes “apparent surface” as the orthogonal projection of visible light-emitting surfaces in a specified observation direction. Amendments include revised definitions for lens, textured outer lens, illuminating surface, and apparent surface, with modified requirements for single lamps with multiple distinct parts. Distance requirements between adjacent parts are adjusted to 75mm or 200mm depending on lamp type.
The agenda includes presentations on UN GTR 21 covering highly integrated systems, FCEVs, and more efficient test methods; UN GTR 22 addressing MPRs, SOCR, readiness monitor and conditioning cycles, and mutual recognition; and UN GTR 25 with OICA comments and updates on MPRs/Energy throughput, Part C virtual distance verification, Annex 2, alternative test methods, normal usage indices, and battery replacement provisions.
The IWG will be informed on the status of identification of AI Use Cases, the revised draft Terms & Definitions Document, and the ongoing collection of proposals for the literature review. The IWG may wish to exchange views concerning guiding questions for AI in automotive, risks of the use of AI in automotive and their management and mitigation, and the consolidated draft for reference document. The 9th IWG on AI session is planned for June 3-4th, hybrid in London, UK and online.
