      Open roadmap issues affecting LabProcICE
      • Duration of validation 2 until October 2012 (6 months)?
      • Evaluation of results and reporting to DTP 11 in Sept 2012?
      • Evaluation of road load data applying gtr until Sep/Oct 2012
        (responsibility?)
      • Beginning of confirmation tests (when?)
      • Decision of issues on DTP level before confirmation test required?


      Need for detailed DTP roadmap / milestones
      Validation relevant input, gtr drafting (incl. definitions), …

       coordinated meeting schedule
       (e. g. necessary conferences with DC & other subgroups)

     Vehicle test mass & inertia classes
      DTP8 status: see WLTP-DTP-08-02 / -04



     Combined approach includes:

     • improved definition of vehicle test mass
       (incl. optional equipment, luggage/payload)

     • step-less inertia approach

     • optional body parts influencing the aerodynamics


     Testing worst case and in addition best case (if requested by manufacturer)

LabProcICE           Bern, 17.04.2012
     Vehicle test mass during Validation phase 2:
     (see parameter setting list)

      mandatory testing with TMH (mass with all optional equipment)

      testing TMH and TML (without optional equipment) at some labs.


     Note: If the maximum mass of options is not known, the actual options mass
     of the vehicle should be derived by weighing it and subtracting the unladen
     mass.
     _____________________________________________________________

     General concern: Payload factors (M1 15%, N1 35%)
      see LabProcICE-117 by Japan and LabProcICE-118 by PSA/Renault

     Discussion at DTP9:
     Combine current proposal with RLD tyre selection criteria?
      test TMH/TML with worst/best aerodynamic and worst/best tyre class
     roadload data

      see DTP-09-13, DTP-09-14 by NL, T&E, icct

     Current DTP proposal:
     selection of tyre according to rolling resistance classes
      choose tyre from worst class (2nd worst if more than 3 classes).

     Japanese proposal (see LabProcICE-126):

      tyre selection class independent

  Multimode gear boxes
  Emissions testing proposal:
   Test agreed worst case
   Compliance with emissions standards in all modes
   Exemptions for modes used in very limited conditions

  CO2 / FE testing proposal:
  (a) Single default mode  test default mode
  (b) No default mode or multi default modes
        test best and worst case, average results of both modes


  Additional provisions:
  - Manufacturer shall give evidence to authority about the emission
    and fuel economy in the different modes
  - Tested options be provided in test report, e.g. for In-Service-testing

  Japan proposal (LabProcICE-119)
  … for excluded modes:

  - Reverse position (transmission)                 - Special off-road modes
  - Low position (auto. transmission)

  … for definition of default mode:

   Selectable switch design                       Selectable shift lever design
     The specific mode always returned to,         The position appeared initially to drive
     when the ignition key is turned on from       the vehicle forward, after started the
     off. (In case of mode A, B, and C, if A is    engine. (In case of [P-R-N-D-S-L], D is
     always activated when the ignition key is     default mode.)
     turned on from off, the A mode is “default
     mode.”

LabProcICE                 Bern, 17.04.2012
  COM and NL:
  Reservation with regard to default mode procedure
   proposal: average best and worst case even in case of a single default mode


  Validation phase 2:
   some labs will test all modes of single default mode vehicles
   decision on how to handle these vehicles afterwards

    - Vehicle preperation
    - Preconditioning
    - Analysis of test result


    Table of Running resistances (see LabProcICE-121 by PSA)
    - Default running resistance table values changed to cope with actual values
    - More data from heavier “light duty vehicles” would be needed.

    Reservation by COM: Default factors should be representative of worst case
     use of table should not be incentivised
     JRC will scrutinize the proposal

    - Issues of the HDV legislation (40 CFR part 1065) shall be adopted for LDV
    - Final rulemaking planned for late 2012

    Conclusion from ME experts:

     PM weighing room specifications have to be discussed with EPA

     Requests concerning analytical gases have to be clarified with EPA

     1066 compliant test cells are WLTP compliant as well
