An update has been given by Alessandro Marotta: ► Report on Test execution Alessandro Marotta, Wolfgang Thiel, Ichikawa‐san and M. Park presented the current test results from the different laboratories. The results will be merged by the VTF Chair into a shared VTF document that will comprise the vehicle codes, the timing and the current status of testing for all participating laboratories. The experimental phase will be finished by the end of September but most vehicle testing will be finished by the end of July. EV testing didn’t start yet but will start with approx. 10 vehicles by the end of June (documents WLTP‐DTP‐10‐05 to ‐07). The validation of low‐powered vehicles (LPV) is not yet planned. The DTP came to the conclusion that a modified Class‐2 driving cycle with extra‐high speed phase shall be created for LPVs because these cars do not have sufficient acceleration capabilities to follow the current Class‐3 test. DHC is asked by DTP to discuss this issue and to seek a solution before DTP11. The validation of LPVs shall start after the modification of the extra‐high phase. India confirmed its participation in VP2. ► Parameter List for RLD Japan provided a first Parameter List for the RLD validation (doc. WLTP‐DTP‐10‐08). LabProcICE confirms feedback until the end of June. ► Assessment criteria for VP2 The VTF Chair presented a provisional list of evaluation issues/assessment criteria for VP2 (see xls‐file by AM). This table is based on the work of the independent evaluation lists provided by the different DTP subgroups. If possible, the assessment of specific evaluation items shall be conducted based on existing UN/ECE‐Regulations. It shall be investigated whether the tolerances, etc. are appropriate or if they can be tightened under the new driving cycle. For other assessment items that are not yet covered by any UN/ECE regulation the DTP subgroups are asked to formulate an initial proposal for assessment. ► Organisation of work The DTP chair presented a flowchart (doc. WLTP‐DTP‐10‐03) on how to organize the work of the assessment/evaluation procedure. The VTF chair will work on detailed planning and will organise the start of evaluation work by the end of June. The DTP Group confirmed the importance of not letting up on the pressure on test execution as the valuation must start well before September. |
