Extended recording from NTSB investigation. The collision sequence involved three alert stages: first alert lasting 5 seconds with visual only or bimodal presentation, second alert lasting 8 seconds with bimodal presentation, and third alert with bimodal presentation and instruction to put hands on the wheel.
Proposal to establish items for the 08 series of UN R10: address immunity-related functions required by multiple UN Regulations through discussion of whether to include these features in UN R10 or relocate electromagnetic compatibility provisions to individual UN Regulations; amend test procedures for complex systems including steer-by-wire, brake-by-wire, and ADAS features to establish clear protocols and reduce unlevel playing field items; improve the general approval process through precise vehicle type description and definition of high-level objectives; describe dwell time selection through ISO standard 1154 as minimum; discuss ISO 17025 evaluation principles; discuss antenna position at 3m versus 10m for best-case and worst-case scenarios; and require robust electromagnetic compatibility protection with critical details described in test reports and information documents.
Proposal to add radiated emission testing requirements in the frequency range 1 GHz to 6 GHz. New clause 6.2.2.5 specifies limits for vehicle measurements at 3.0 ± 0.05 m antenna distance using peak and average detectors, with limits of 70/50 dB(V/m) for 1000–3000 MHz and 74/54 dB(V/m) for 3000–6000 MHz. New Annex XY describes test methods using IEC 61000-6-3 Ed.4.0 and CISPR 12 provisions. New clause 6.5.3 establishes ESA broadband type approval limits with higher thresholds. New Annex XZ prescribes ESA measurement methods, including test arrangements for REESS charging mode coupled to the power grid.
The IWG-EMC 52nd meeting is scheduled for 7 May 2026 as a web conference. The agenda includes feedback from the GRE 94th session regarding Supplement 3 to UN R10.07 and discussion of the roadmap for 08 series of amendments with proposals from Contracting Parties and non-governmental organizations. The session will address GRE-94-56-Rev.2 and documents covering topics such as harmonics limits, charging conditions, immunity requirements, and radiated requirements. The next meeting is scheduled for 1–2 July 2026 in Paris.
The agenda includes discussion of DSSAD regulatory text guidance, EDR Step 2 proposals comments, and EDR for ADS. The next meeting is scheduled for September 15-17, 2026, as a hybrid event in Europe.
Systems with ACSF B2, D and E functionality cannot be approved to UN R79 unless incorporated within a DCAS complying with UN R171. However, these functionalities may exist independently of DCAS, requiring clear distinction. Where not part of DCAS, this must be specified in the EDR regulation. A new EDR data element, “DCAS status”, could encompass ACSF B2, D and E functionalities. These functionalities are now treated either as individual functions or as components of DCAS.
Proposal to amend UN GTR No. 9 (Pedestrian safety). In Part B, chapter 6, paragraph 6.3.1.2.4., replace “675 Nm 25 Nm” by “a minimum of 650 Nm but no more than 850 Nm”. In Part B, chapter 8, paragraph 8.2.4.1., replace “675 Nm 25 Nm” by “a minimum of 650 Nm but no more than 850 Nm”.
69. The expert from GTB presented a status report of the GTB Working Group activities (GRE-71-33, GRE-71-34, GRE-71-35 and GRE-71-36).
Brief presentation raising question over the necessity to have triangular reflectors on the rear of large trailers and seeking greater flexibility in such rear reflectors.
