Proposal to clarify components and functions of the ADS and other vehicle systems relevant to meeting the requirements of the regulation (paras. 5.3.1.4.2 (GTR)/7.3.1.4.2 (UNR)). The revised text specifies that other vehicle systems could include shared components or functions such as sensors, map data, and GNSS used for assistance systems or positioning. Information from outside the vehicle may be included if used to meet regulation requirements. The manufacturer could use different diagram types provided information is present, and additional information regarding wireless links could be included.
Proposal to revise the explanation for para. 8.3.3.1 to clarify the relationship between assessment of the manufacturer’s testing under 8.3.2 and confirmatory testing. The revision adds language specifying that during assessment, the assessor can determine the need for additional scenarios or variations and shall convey this information to the manufacturer requesting additional test evidence under agreed upon protocols. The revision changes “trustworthy” to “accurate” and specifies that confirmatory testing verifies the accuracy of the manufacturer’s testing, with the exception of real-world testing that cannot be precisely replicated.
Proposal to revise the explanation for para. 6.1.2.1. of the ADS UN Regulation. The revision clarifies that where collisions involving the ADS occur during the approval process, including manufacturer’s on-road testing or confirmatory testing, a root cause analysis must be done and an explanation provided. Where the ADS is determined to have played a role in causation, the manufacturer will provide evidence of how related causal factors have been addressed in the final ADS prior to approval. Post-deployment collisions are covered by the ISMR process as implemented within national law.
The Informal Working Group on Automated Driving Systems identified topics for future consideration organized into four lists: items not addressed in original versions of the GTR/UNR; existing items requiring amendment or improvement; items relating to operational implementation; and other items. List 1 includes remote assistance, ODD description taxonomy, external human-machine interface provisions, and connectivity considerations. List 2 includes ADS to ADAS transitions, Data Storage Systems for Automated Driving, ADS deactivation, in-service monitoring and reporting, and safety case requirements. List 3 addresses interpretation document improvements, mutual recognition provisions review, system updates and thresholds, and practical implementation of in-service monitoring. List 4 includes text streamlining to remove duplication and improve clarity.
