Proposal to introduce provisions for type approval of Moving Off Information System Component and Separate Technical Unit. The supplement adds Part III to UN R159 establishing approval requirements for MOIS Components and STUs, modifies Part I to align with the new component-based approval pathway, and adds Part II to govern vehicles installing previously approved Components or STUs. Manufacturers may choose between Component approval (largely vehicle-independent) or STU approval (tailored to specific vehicle families) to streamline market introduction of MOIS technology.
Proposal to introduce provisions for type approval of Moving Off Information System (MOIS) Component and Separate Technical Unit (STU) by establishing three approval pathways: Part I for vehicles with MOIS, Part II for vehicles with installation of approved MOIS Component or STU, and Part III for MOIS Component or STU themselves. The system detects pedestrians and cyclists in the forward blind spot area and provides information and collision warning signals during low-speed moving off manoeuvres at speeds of 10 km/h or less. Technical requirements cover detection performance for speeds 3–5 km/h for potential moving off and 0–10 km/h for low-speed operation, automatic deactivation on system failure or sensor contamination, manual deactivation through intentional driver actions, and signals that are deactivated together upon failure. Test procedures include static crossing tests, longitudinal stopping and moving off cyclist tests, and failure detection tests performed on flat dry asphalt under natural illumination conditions.
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.
Proposal to establish uniform provisions concerning the approval of M₂ and M₃ special purpose vehicles designed specifically for the carriage of children to assist in the prevention of children being left inside. The regulation applies to vehicles of categories M₂ and M₃, class B and III. Vehicles shall be equipped with a physical inspection system that engages when the vehicle master control switch is turned off and generates an external visual and audible warning if not disarmed within 3 minutes for buses or coaches not exceeding 22 passenger seats, or within 5 minutes for those exceeding 22 passenger seats. The physical inspection system shall not influence the bus or coach’s performance or safe operation, and failure of the system shall not affect safe operation of the vehicle.
This regulation establishes uniform approval provisions for Advanced Emergency Braking Systems (AEBS) fitted to motor vehicles of categories M1 and N1. The AEBS shall automatically detect imminent forward collisions with vehicles, pedestrians, or bicycles, provide driver warning, and activate vehicle braking to avoid or mitigate collision severity. The system must meet specified performance requirements under defined test conditions for car-to-car, car-to-pedestrian, and car-to-bicycle scenarios. Requirements include collision warning provision, emergency braking of at least 5.0 m/s², active speed ranges, driver interruption capability, deactivation controls, and warning indications. Testing procedures, vehicle conditions, target specifications, and virtual testing provisions are specified.
Document confirms homework points for consideration of night-time requirements for car-to-pedestrian scenarios in UN R152. Topics include vehicle categories M1 and N1, crossing and longitudinal collision types, farside/nearside pedestrian direction, pedestrian walking speed of 5 km/h, lighting conditions, collision points at 25%, 50%, and 75%, dummy types, vehicle activation speeds of 30–60 km/h without obstruction and 40–50 km/h with obstruction, and speed reduction. Daytime requirements discussion covers car-to-car speed reduction at 80 km/h, collision point revision, and car-to-pedestrian speed reduction review based on current technology.
Terms of Reference and Rules of Procedure for the Informal Working Group on Prioritization (IWG-Prio). The IWG-Prio shall develop recommendations on prioritization criteria including regulatory urgency, safety, environmental, fuel efficiency and security benefits, resource implications, field data availability, technology maturity, and alignment with ITC and WP.29 strategies. The group shall conduct a high-level review of ongoing and proposed activities and develop recommendations regarding initiation and continuation of regulatory activities. The IWG-Prio shall identify opportunities to improve efficiency of WP.29 activities including coordination among groups, meeting scheduling, digitalization, information sharing, and establishment, continuation, review and closure of working groups and task forces. The group shall prepare recommendations for consideration by AC.2 and WP.29 at their November 2028 session.
Note by the secretariat reporting on results of the 131st GRSG session presented to WP.29 in June 2026. GRSG adopted revised Terms of Reference for the Informal Working Group on Driver Distraction and Drowsiness Warning Systems, extending its mandate until October 2028 to finalize the 01 series of amendments to UN R182 and UN R183. WP.29 recommended to AC.1 the adoption of 36 amendment packages to UN Regulations under GRSG responsibility. Mongolia acceded to the 1958 Agreement on 29 April 2026, with entry into force on 28 June 2026. WP.29 endorsed continued work on IWVTA and DETA.
