Evaluation of candidate procedures - Status & Reporting - RDE-LDV working group 28 June 2012, Brussels, EU Martin Weiss Pierre Bonnel DG - Joint Research Centre (JRC) IET - Institute for Energy and Transport

Evaluation matrix Objectives of the evaluation matrix: To provide a synthetic view of criteria which were used to assess the technical feasibility and potential strengths and weaknesses of the tow candidate procedures To provide stakeholders with know-how about the procedures and to therefore to support objective decision making Not to provide any ranking system establishing priority criteria and/or weighing

Main principles for establishing the evaluation: Whenever possible, ‘supporting evidence’ was provided (e.g. test results, drivability) Otherwise, the evaluation was made based on the best available knowledge Stakeholders’ input is reflected in the unconsolidated and consolidated evaluation matrix Consolidated matrix tentatively reflects the consensus. Evaluation matrix

Current status: Final stakeholders input received and discussed during the previous RDE meeting Consolidated matrix to be integrated in the Phase 1 report (Possibly opening the door for last comments / remarks) Evaluation matrix

Evaluation matrix – recent changes Splitting the first criterion into two criteria Preventing detection and by-passing of emissions test by the engine control unit Preventing a too narrow calibration of vehicle technologies Adding a footnote on the importance of reproducibility and repeatability for manufacturers Adding a footnote on initial costs of implementation for manufacturers and technical services Mentioning the relevance of traffic conditions for the “Certainty of the certification schedule” Mentioning the uncertainty of GPS data in the “Accuracy of the analytical equipment” RC: medium evaluation regarding “Influence of measurement procedure/equipment on results” RC and PEMS: medium evaluation regarding “Coverage of ambient conditions”

Evaluation matrix – recent changes Changes proposed by 1 stakeholder (27 June) Changes marked red in the recent evaluation matrix (28 June) and – due to late submission - subject to discussion and potential revision
