Excerpts from session reports related to this document
WLTP-DTP | Session 9 | 16-18 Apr 2012

1. LabProcICE reported on the working progress (see document WLTP‐DTP‐09‐05). Several bilateral meetings held between LabProcICE and drafting coordinator to deliver input to draft gtr text.

2. Definitions will be put into a database to be able to handle the amount of definitions. General documents of the GRPE‐chair (document WP.29‐156‐26) concerning the definitions will be considered. DTP is responsible to deliver definitions for GTR‐text. DC will schedule web Conferences with DTP‐Subgroups for further progress on definitions.

3. Multimode‐Gearboxes:

  • a. Proposal for excluded modes and definition for default mode commonly agreed (see LabProcICE‐119).
  • b. New Reservations by COM and NL since last LabProcICE‐meeting regarding the default mode procedure:
    • i. Alternative Proposal to test best and worst case instead of default mode.
    • ii. Decision will be taken after VP2.

4. Evaluation Issues for Validation 2 (See Guidance document WLTP‐DTP‐09‐10):

  • a. Multiple issues addressed, that must be evaluated after finishing VP2;
  • b. Decision on Evaluation Issues must be prepared in August. Therefore a fundamental input must be given out of VP2.

5. Road Load Determination

  • a. Reservations by COM since last LabProcICE‐meeting concerning the table of running resistances, that the default factors should be representative for the worst case.
  • b. Validation of RLD necessary. VTF is considered to be responsible for the organization of the validation. VTF‐chair will be informed by DTP‐chair.

6. Measurement equipment: Part 1066 compliant test cells are WLTP compliant as well (but not vice‐versa).
