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), …

Definitions
Current status:- LabProcICE gtr draft (LabProcICE-112)- Gaseous Fuel definitions (GFV-18-02)- DC documents (WLTP-2012-002 /-003 /-004) (replacing LabProcICE-049 /-050)
WP.29: Task Force Group under GRPE to develop a frame system of terms, definitions and classifications regarding vehicle propulsion systems(see WP.29-156-26)
Next steps:
- Separate meetings with DC and representatives from all subgroups will be scheduled by DC
- Definitions will be imported into a database.

Vehicle test mass & inertia classesDTP8 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)

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%)

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

Approach needs to be discussed in connection with
family concepts
see initial discussion document by Bill Coleman (DTP-09-02)
Analysis of family concepts in ECE R83.06 - test families
- definitions
- modifications of the vehicle type
- extensions to type approval

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

slide 15
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
The specific mode always returned to, when the ignition key is turned on from off. (In case of mode A, B, and C, if A is always activated when the ignition key is turned on from off, the A mode is “default mode.”
Selectable shift lever design
The position appeared initially to drive the vehicle forward, after started the engine. (In case of [P-R-N-D-S-L], D is default mode.)
WLTP 9th DTP MeetingBern, 17.04.2012
DTP Subgroup LabProcICE
slide 16
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___________________________________________________
GSI
To be tested in validation 2 (if available).

VTF documents which are continously reviewed/ updated by LabProcICE: (note: current revisions are provided by VTF manager)
Parameter setting list:
Major amendments since DTP 8:
- Test mass and inertia approach – provision for missing data TMH/TML- Position of temperature sensor precised
(“outlet” of the cooling fan instead of „in the vicinity”).
Excel data sheet for reporting of results
Mode Construction
- review of DHC proposals by DTP experts (LabProcICE/EV)- amendment of UTAC/JRC to allow subsequent testing

Road Load Determination
- excluded from validation phase 2
- Japan requires validation of RLD procedure, ACEA agrees.
- gtr changes to ISO are relevant for regional correlation exercises
RLD Validation to be included in WLTP roadmap

Road Load Determination
Japanese proposals (see LabProcICE-120rev1) on:
- 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

Measurement Equipment
40 CFR Part 1066 (see LabProcICE-124)
- Succeeding legislation for current US regulation (40 CFR part 86)
- 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

Measurement methods of HC emissions acc. to R 83.06(see DTP-07-13 by Poland)
Comments were reviewed by ME experts
Modification consists of introducing the cutter efficiency for ethane in the
NMHC calculation (consistency with gtr4).
principal agreement
LabProcICE developed gtr draft proposal (see LabProcICE-123)
Correction also needs to be integrated in R83
