Informal Group on Heavy-Duty Hybrids | Session 13 | 21-22 Mar 2013
Borlänge
Agenda Item 8.
Development of the GTR

8.1 Report of the Drafting Group

The Chairman gave a brief report from the meeting of the HDH drafting group on the two days before the 13th HDH meeting. It was agreed and confirmed that the HILS method would be developed as an annex to gtr n° 4. Starting point is the Japanese regulation. Modifications to the Japanese regulation and any additional items (e.g. thermal models) would be included based on the input from the HDH work program. Unfortunately, the technical secretary responsible for the editorial work has not yet been nominated, but the EU Commission is hoping to solve the problem, soon.

Due to the meanwhile very tight timetable, the drafting group will need to call for web/phone meetings between the face-to-face meetings.

8.2 Restructuring of GTR No. 4

The secretary briefly introduced the first very rough draft that he had prepared for the meeting of the drafting group. The details of the HILS method will be incorporated into a new Annex 8 to gtr n°4. For the time being, this Annex is also planned to include the powerpack test procedure. However, it might be more appropriate to provide for a separate Annex. This issue will be further discussed.

8.3 General contents

In general, the content will largely follow the Japanese procedure for HILS and the EPA procedure for powerpack testing. The drafting group will only include items into the gtr that have been approved by the IWG. For a transparent process, the draft versions prepared by the drafting group will be uploaded to the HDH website for review by the IWG members, whenever a new draft is available. Any editorial comments should be submitted to the technical secretary (to be nominated), any other comments to the IWG for discussion.
