List of Considerations on Changes to the RD-ASEP Specifications

The Task Force Data Analysis completed data revision for RD-ASEP specifications, identifying errors and inconsistencies. The document lists considerations for database improvements, including updating limits to UN R51.03 phase 3, clarifying vehicle reference speed definitions, correcting reported loads exceeding 100%, selecting correct parameter tables, and addressing gear shifting detection. Additional recommendations involve determining acceptable factor x ranges, resolving minimum dynamic calculation inconsistencies, increasing vaMAX validity thresholds, and reconsidering AVAS term applicability for hybrid vehicles.

Excerpts from session reports
WP.29 | Session 166 | 23-26 Jun 2015

57. The secretariat presented informal document WP.29-166-07 detailing the different financing options for DETA. The secretariat explained that there were two options to cover financing: either by UN regular budget or by extra-budgetary funds. The secretariat noted that the option of establishing a trust fund (an example of extra-budgetary), would be the preferred option of the secretariat.

58. The representatives of Belgium, Germany, the Netherlands, and Switzerland expressed their support of funding DETA by additional regular UN budget. The secretariat explained that the request for additional budget should come from the member States and that the secretariat was searching for precedent cases, so that the practical steps on how to proceed could be identified.

59. The representative of Germany offered to host DETA in the beginning by his country, if necessary, until UN financing issues are resolved.

60. The World Forum decided to continue discussions on the matter at the next session of WP.29.
