ADS guidance and interpretation document: Proposal to amend ADS-20-12
Reference Number: ADS-20-14

Proposal to amend ADS-20-12 (consolidated guidance document). The ADS shall have strategies to detect and respond to instructions from road safety agents. For ADSF-1, this allows transfer of control to the fallback user. Manufacturers may use non-ADS strategies including remote intervention or permitting the road safety agent to drive. Examples of instructions include pull over, give way, stop after collision, move out of way, avoid specific road, and not overtake. Instructions may be issued via lights, sirens, audio messages, written signs, or light bar messages.

ADS guidance and interpretation document: Proposal to amend ADS-20-12
Reference Number: ADS-20-13

Proposal to amend ADS-20-12 (consolidated guidance document). The terms faults, malfunctions, and abnormalities lack distinct meanings in requirement 6.1.4.2. The revised explanation clarifies that “faults, malfunctions, and abnormalities” do not have specific distinct meanings and cover any failure in the ADS’ capability to perform the DDT within the ODD. The three kinds of issues encompassed are warning signals from other systems, faults without warning signals a driver would perceive, and faults within the ADS itself.

EDR/DSSAD informal group status report to GRSG
Reference Number: GRSG-131-14

The IWG on EDR/DSSAD developed draft proposals for Event Data Recorder for conventional and automated/autonomous vehicles and Data Storage System for Automated Driving. Completed work includes UN R160 on light duty vehicle EDR, UN R169 on heavy duty vehicle EDR, and DSSAD requirements. Current activities address EDR Step 2 and DSSAD Phase 2. The IWG resolved assessment subjectiveness for vehicles with maximum mass up to 12t through a proposed Supplement 2 to UN R169.

Meeting Sessions: 131st GRSG session (13-17 Apr)
Document date: 10 Apr 26
Relevant to: UN Regulation No. 160 | Event Data Recorders, WP.29 Regulatory Project | Data Storage Systems for Automated Driving, and UN Regulation No. 169 | Event Data Recorders (EDR) for heavy vehicles

GRSG | Session 125 | 27-31 Mar 2023

27. The expert from the Netherlands on behalf of the IWG on Event Data Recorder (EDR) / Data Storage system for Automated Driving Vehicles (DSSAD) introduced the status report (GRSG-125-25) of the group. He informed GRSG that the IWG had completed the light duty vehicle EDR performance elements appropriate for adoption in the 1958 and 1998 Agreement Resolutions or UN Regulations, completed UN Regulation No. 160 accordingly and DSSAD requirements within UN Regulation No. 157 (Automated Lane Keeping System). He also announced ECE/TRANS/WP.29/GRSG/2023/11, ECE/TRANS/WP.29/GRSG/2023/12 and ECE/TRANS/WP.29/GRSG/2023/15 on the acceleration data accuracy verification procedures. Moreover, he explained that the IWG had developed proposals on EDR for Heavy Duty Vehicles (HDV), as a: (a) new UN Regulation (ECE/TRANS/WP.29/GRSG/2023/13 amended by GRSG-125-07) and (b) a guidance document on EDR for HDV appropriate for adoption in 1958 and 1998 Agreement Resolutions or Regulations (ECE/TRANS/WP.29/GRSG/2023/14 amended by GRSG-125-08). He explained that the proposals were based on an existing Society of Automotive Engineers standard, data, analyses, research and contains unique triggering of acceleration, safety-systems and last stop.

28. Finally, GRSG agreed to combine ECE/TRANS/WP.29/GRSG/2023/12, as amended below, and ECE/TRANS/WP.29/GRSG/2021/32 as amended by GRSG-122-35 and submit them as proposal for amending the Guidance on EDR Performance Elements to the November 2023 session of WP.29 for information only. Moreover, it was agreed to send ECE/TRANS/WP.29/GRSG/2023/14 and GRSG-125-08 to the IWG for reconsideration.

Annex 1, Table 1, amend to read:

Longitudinal acceleration

If Recorded0–250 ms or 0 to End of Event Time plus 30 ms, whichever is shorter.500-50 to 50g/- 10%101gPlanar
