5. The expert from the Republic of Korea introduced the progress report (GRSP-72-11) of Informal Working Group on Deployable Pedestrian Protection Systems (IWG DPPS). He informed GRSP that the following issues had been resolved by IWG: (a) detection area definition, (b) numerical simulation for Head Impact Time (HIT) against Wrap Around Distance (WAD) information (linear regression), (c) head test area marking with un-deployed DPPS and (d) overshooting phase (dynamic testing). He added that discussion was ongoing on a new wording in the preamble and a final agreement on HIT. He introduced the text of the proposed amendment to the preamble (GRSP-72-08) and the amendment to the text of the regulation (GRP-72-09 amending ECE/TRANS/WP.29/GRSP/2022/2). Finally, he informed GRSP that the final report of IWG would be submitted to the May 2023 session of GRSP.
