TPM | Session 1 | 28-29 Nov 2007 |
The following documents were presented and explained during the meeting. Only the most important comments are reported below. Principles of ECE-Regulation (Japan) Public consultation on outline proposals for a Regulation of the European Parliament and the Council on Advanced Safety Features and Tyres (CLEPA). The document was distributed without detailed discussion. Time Based Warning (TBW) – For constant Tyre Pressure and CO2 reduction (BMW). Mr. Hein (BMW) introduced this proposal as a short term solution without jeopardizing middle or long term solutions. UNECE R64: RFT & RFWS Tyre Industry Position (ETRTO) Low pressure warning of run-flat-tyres is of great concern for the tyre industry with regard to product liability (2001/95/EC). Warning thresholds need deliberate discussion. Notes for UNECE Informal GRRF Ad-Hoc TPMS WG Meeting in Bonn on Nov. 28&29, 2007 (CLEPA). Experts from Schrader Electronics and Siemens VDO presented a first draft for a cost/benefit-analysis of TPMS. This draft is based on data from USA. Under-inflation measurements, types, standards & rules (ISO) This document shows that depending on the TPMS technical principles, under-inflation can be detected more or less easily. Informal document No.GRRF-62-17 UNECE/TRANS/WP.29/GRRF – Setting up an informal group on TPMS /Terms of Reference OICA Some experts felt that this group should develop a more.sophisticated solution from the beginning. The German government, however, is convinced that TBW is a simple solution which could be realized by the vehicle manufacturers without great problems and thus improve the situation on the road very quickly, while giving this group the opportunity to develop a more sophisticated and well balanced cost-effective solution without time pressure. The German government will therefore prepare an informal document for the next GRRF meeting to introduce TBW as a short term solution. As defined in the terms of reference the first task will be to identify the potential for improvement of road safety and fuel efficiency. In the opinion of some experts, besides safety, fuel efficiency or environmental protection has the highest priority. In order to identify the potential for improvement it is necessary to know the present situation on the road, that means figures and data about the number of vehicles which are driven with under-inflated tyres, the number of under-inflated tyres on each vehicle and the degree of under-inflation. It was decided to establish a task force for the the collection of such data. Mr. Wim Verhoeve from CLEPA (w.verhoeve@clepa.be) agreed to be chairman of the task force. Members will be experts from OICA, CLEPA, ETRTO and governments, Japan will be included by e-mail contact. The task force should have its first meeting at the beginning of 2008, in any case before the next meeting of this group in order to be able to present first results for the next meeting. |
