Excerpts from session reports
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).
