GRPE | Session 65 | 15-18 Jan 2013

55. The Chair of the VPSD informal group introduced a report (GRPE-65-12) containing a proposal for a framework system of classification of the main terms and definitions to be annexed to Special Resolution No. 1, concerning the common definitions of vehicle categories, masses and dimensions (S.R.1) and the Consolidated Resolution on the Construction of Vehicles (R.E.3). Having clarified that he sees GRPE-65-12 as a living document requiring updates, and supported by the overview presented in GRPE-65-13, he explained that GRPE-65-12 contains definitions regarding powertrains and powertrain components (e.g. energy storage system, energy delivery system, energy converter and drivetrain), vehicles (such as mono fuel, bi fuel, flex fuel, dual fuel, hybrid, electric, fuel cell, etc.), as well as attributes of vehicles and powertrains (external chargeability, energy recuperation, energy consumption, emissions, state of charge, electric range, etc.).

56. The expert from Hungary pointed out that the definitions should target fuels. The Chair of VPSD clarified that fuels are not included at the moment because the current focus of the work is on the WLTP activities, clarifying that the extension of the scope to fuels can certainly be foreseen in a later stage. The expert from India expressed his support for this work, underlined the need for precise definitions and the importance to link them with regulatory texts. The expert from Sweden offered inputs on heavy duty vehicles.

57. Responding to a request by the Chair of the VPSD informal group, the expert from OICA expressed the interest in having informal groups meetings. He also offered to share a database on definitions available with the VPSD group. The expert from NGV Global expressed interest in the VPSD work and underlined the need to maintain e-mail contact besides informal meetings. He expressed the view that existing ISO definitions be considered as guidelines for the VPSD definitions, particularly for gaseous fuel systems. The expert from CLEPA also supported the VPSD work.

58. GRPE agreed to the structure and approach suggested and endorsed the decision to hold VPSD meetings, asking the secretariat to create a VPSD area on the UNECE web site for the upload of relevant documentation. GRPE also agreed to the upload of the database that OICA offered to deliver, on the UNECE website (VPSD area).
