UN R46: Alignment with UN R26 and R61
Reference Number: GRSG-131-09

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.

CLIV: Status report to GRSG
Reference Number: GRSG-131-08

CLIV is developing a new UN Regulation for vehicle categories M1, M2, M3, and N1 in Phase 2. The draft regulation requires visual and audible external warnings upon detection of a child left in a vehicle. Visual warnings use direction indicator lamps flashing in SOS morse code pattern for at least 15 seconds, then off for no more than 30 seconds, repeating for at least 10 minutes. Audible warnings must exceed 60dB(A) following the same timing pattern. The IWG requests guidance on potential amendments to UN R48, UN R28, and UN R165.

UN R169: Proposal for a Supplement 3
Reference Number: GRSG-131-07

Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.

UN R160: Proposal for a 03 series of amendments
Reference Number: GRSG-131-06

Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.
