46. GRVA received information on the progress made by the Technical Committee 22 of ISO concerning their activities on test scenarios for the evaluation of ADS, presented by the expert from China (GRVA-16-24) and the expert from Japan (GRVA-16-31). The expert from CLEPA highlighted the importance of this work done by ISO.

29. Finally, GRSG considered a presentation (GRSG-125-14) from the expert of China that provides information on the introduction of the EDR technology into the legislation of his country. The GRSG Chair suggested that GRSG-125-14 could be considered in the future work of the IWG. The expert from EC underlined that the document would be useful for the step 2 of EDR development but not for the current one since discussion was too much advanced. The expert from the United States of America remarked that EDR shall remain focused on crash related events and not as a data logger for non-crash elements/events.

12. The expert from China reported on their research on measurement methods for heavy-duty vehicles in multiple driving mode conditions (GRBP-77-28). The experts from Germany and OICA commented on the study.

118. The expert from China introduced GRVA-15-32, presenting a new braking concept for electric motorcycles. He clarified upon request that this new braking system would only include an electric brake on the rear wheel, without friction brake. The expert from CLEPA asked if the concept would include a resistor for that case where the battery would be fully loaded. The expert from IMMA explained that this concept was not in line with the definitions of UN GTR No. 3 and UN Regulation No. 78. GRVA noted that this concept could be presented at the EMB workshop, if desired.

Proposal to clarify collision avoidance where reasonably foreseeable and preventable.

Proposal to clarify misuse prevention where reasonably foreseeable.

57. The expert from China presented GRVA-14-19, with the views of China on open issues to be addressed for effectively tackling ADS performance assessment and testing, as well as with other suggestions. The expert from Canada recalled the leadership function of the expert from China at IWG on FRAV and the possibilities for her to bring these suggestions to the attention of her group, directly. He invited China to share suggestions directly with the IWG on VMAD subgroup one. The expert from the United States of America echoed Canada’s comments. The expert from China clarified that, for the sake of good governance, China preferred to share these considerations with GRVA, the formal and parent body of IWGs on FRAV and VMAD, first. GRVA noted these considerations, that would be cascaded down to the IWGs.

67. The expert from China introduced GRVA-14-20. He noted that GRVA’s name mentioned connected vehicles and that GRVA deliverables on connectivity were limited to cyber security and software updates, so far. He suggested that GRVA consider new tasks in that field. He stressed that whether a vehicle can send and receive data accurately was an important factor for the vehicle to realize connectivity-related functions. He stated that Vehicle-to-Vehicle (V2V) data interaction was important to materialize the potential of technology in the field of road safety. He noted the standardization and regulatory activities of ISO, ITU, the International Electrotechnical Commission (IEC), SAE International, European Telecommunications Standards Institute (ETSI) and the Intelligent Transport System (ITS) Connect Promotion Association of Japan. He proposed that GRVA carry out preliminary research on V2V data interaction, data content, data format, data broadcast rules and communication performance requirements. He suggested to address three questions, (a) whether the subject of V2V data interaction would be a system of the vehicle, (b) at what level such activities could be carried out, and © how to coordination the formulation of harmonized technical requirements. The proposal received comments from the experts from Canada, France, Germany, Japan, ITU and OICA. GRVA agreed to explore the need for such activities, to check if other GRs or the IWG on ITS would have a role. GRVA agreed to inform and to consult AC.2 and WP.29 at their November 2022 sessions on the way forward with this technical item.

CATC Data Study and Measurement Methods Research

10. The expert from China reported on their research on measurement methods for passenger vehicles and trucks in multiple driving mode conditions and to characterize the current situation and possible developments (GRBP-76-29). GRBP invited TF VS to consider this study as well.
