WLTP in TA processTask Force (subgroup of AdminWG)Brussels – 21st-22nd May

E.Collot (UTAC) & R.Gardner (TRL)

21-22/05/2015 TA process with WLTP 1

• Framework of TF meeting– Test– Information document (xx/2015 // annexes I & III 2007/46)– Test report (xx/2015)– Certificate (xx/2015)– Families– Extension rules– Individual vehicle– COP– Test results (annex VIII 2007/46)– TVV (annex II part B 2007/46)– CoC (annex IX 2007/46)

• Reminder– The purpose of this group is to determine how to approve a vehicle and make recommendations to

the AdminWG. – It will then be the AdminWG that agrees and prepares the requirements/text to be included in the

new EU WLTP regulation.

• Remarks– This is a working document for the expert TF: comments, proposal and agreement are blue– Each reference to a regulation is written in ‘Times new roman’– When the Vehicle Low (VL) is mentioned: when existing (interpolation approach)– Actions are highligthed in red

Introduction



TestCurrent agreement / Text Proposal/agreement/comment

Choice of the tested vehicles The choice of VL and VH is an agreement between TS/TAA and OEM The information about the tested vehicle is provided in the information document

Checking of their parameter (by testing, calculation)'virtual' vehicle (not produced) agreement

Same vehicle tested (H and L)The only difference between VL and VH is the roadload

Number of test- CO2/FC rules (dp

1, dp2)

CO2/FC rules are at least on combined results. Are they applicable for each phase?Action EC to answer – see also conclusion from EU WLTP meeting 11/5/15.- Pollutant rules

Interaction? JRC proposal (A. Marotta) for GRPE (June) ongoing CO2/FC: results on test report (692/2008) and

test result (ann VIII 2007/46) Pollutants PASS/FAIL criteria (character) +

results in the test report (692/2008)Question: KBA/German (or other MS) position?


Information document 1/4Current agreement / Text (xx/2015 annex I appendix 3)

Proposal/agreement/comment

Declaration of:- 14°C family- Roadload family- RDE family?

How-where to identify the families?- Roadload + ATCT: test results (e.g. coastdown results in the document) - RDE: ?

What about TA issued by different TAAs (e.g. for roadload and ATCT)?Responsibility lies with the TAA that issues the type approval certificate (with information from different TS)

1. GENERAL CONSTRUCTION CHARACTERISTICS OF THE VEHICLE

The only difference between the physical VL and VH is the roadload (and transmission in tolerance of 0-8%)




2. MASSES AND DIMENSIONS (in kg and mm) (reminder: TM of Vind : actual mass of Vind + 25 kg + mass representative of payload)

MRO, maximum and reference masses for VL and VHTM of VL and VH Modification of appendix of information document (“test conditions”)(ann I&III of 2007/46) 2.6.2: mass of the optional equipment To be changed in “maximum mass of…”

Need to check alignment of 2007/46 and 692/2008 for Mass in Running Order

3.5. CO2 emissions/fuel consumption (manufacturer’s declared value) for VL and VH:- CO2-FC declaration in WLTP

on each phase + combined final values (after corrections)

During transient period in NEDC on combined and phases (for metamodel/double testing) Other ‘short-lived’ regulation on correlation

could be introduced for transitional period interpolation family needed (physical WLTP

results) for MM




6.6. Tyres and wheels6.6.1 Tyres/wheels combination(s)(a) for all tyre options indicate, size designation, load-

capacity index, speed category symbol, rolling resistance to ISO 28580 (where applicable)

(b) for tyres of category Z intended to be fitted on vehicles whose maximum speed exceeds 300 km/h equivalent information shall be provided; for wheels indicate rim size(s) and off-set(s)

(quite the same in ann I & ann III of the 2007/46) Action To be clarified/harmonised by EC (KS)

VH and VL RR is already included in the “test conditions” appendix 6.6. Tyres dimensions (a) for all tyre options indicate, size designation, load-

capacity index, speed category symbol, rolling resistance to ISO 28580 (where applicable)

(b) for tyres of category Z intended to be fitted on vehicles whose maximum speed exceeds 300 km/h equivalent information shall be provided; still relevant? R117? Not included in the 2007/46for wheels indicate rim size(s) and off-set(s)

Aerodrag of VH and VL See appendix “test conditions”3.2.6.6 and 3.2.6.7 Spark plug + ignition coil (ann I 2007/46) to be added in the information document (annI app3 of xx/2015)

Erased from “test conditions” appendixSee attached document

4.7. Maximum vehicle design speed (in 2007/46 not in xx/2015)

to be added for harmonisationInformation on tests conditions

• Gear shift – Idling speed same as 3.2.1.6. (annex 1 appendix 3 xx/2015 and annexes I & III 2007/46)– Additional safety margin (2 values) – nmin drive (if the OEM declares higher than GTR calculated values)

– Maximum power curve (Pwot(nnorm))

Need to be added in the information document Action AdminWG

• EC proposal to add result of the tool for gearshifting (VH & VL)– It represents around 150 points. – Action: H. Steven will have a proposal to have one number (for instance averaging gear shift)

Unic number specific to one vehicle (one for VH, one for VL) Aim: to have a checksum -> easy to control / easy to calculate

EC agrees with this idea (need to see the proposal)

Action TF to propose where it could be register: – in the proposal « information on tests condition »? – or test report (xx/2015)?

• Reminder about Gearshfting:– Need a full description of the calculation in xx/2015 – Add an Excel sheet for calculation? (EU or UNECE websites): Action

• Remark:– Gear shifting depends on specific characteristics of the tested vehicles (effective radius)

Information document 4/4



Test report (xx/2015) 1/3Current agreement / Text Proposal/agreement/comment

Minimal data needed:- raw results- corrections

o CO2/FC: Ki, RCB, 14°C, …o Pollutants emission: Ki, DF

- Roadload

- VH-VL; options, masses and RR

- CO2 family limits

Rounded values for final result onlyGTR to define metric precision for all the intermediate and final resultsAction – CL to raise with GTR drafting group

Correlation exercise independent regulationVehicle class (which WLTC driven: class 1, 2, 3a, 3b, downscaled?)

Roadload: other report

See ‘information on test conditions’ (slide 6)

Detailed results of roadload family?

To be checked for extension



Electrified vehicles:- Transitional period: choice of vehicle to test

(no interpolation approach)- Decide how to deal with hybrid vehiclesReminder of electrified vehicles results: WLTP:- CD (OVC+PEV): Criteria Emissions, FC, CO2, AER, EAER, RCDC, RCDA, EAC- CS (OVC+NOVC): Criteria Emissions, FC, CO2

WLTP city CD (OVC+PEV): AERcity, EACcity

ACEA proposal: still ongoing Action ACEA to provide a proposal

Need a template of minimal information ? A template needs to be defined (minimum information) Action TF to write a proposalFrom certificate template (first)

ATCT Action LB + A. Eder to check if the text is clear 3.8.3 FCF documentation requirement (sub annex 6a) to be clarified

How and when to apply?



Other tests during transitional period:- OBD- Durability- Ki

For Ki: Information document3.2.12.2.1.11.1 (annex I appendix 3 xx/2015 // 2007/46 annexes I and III) To be modified to specify which type 1 (NEDC

or WLTP)

For those tests : if NEDC NEDC roadload used OBD: ACEA + EC discussions ongoingAction EC+ACEA Ki (phase 1b) included in xx/2015?

If NEDC Ki and WLTP Ki could be used it has to be declared somewhere

Ki and Durability : accepted to keep NEDC values for a transitional period Action ACEA to provide a proposal (especially on Ki)

Discussion:- Ki NEDC used until monitoring ‘base year’

because of Ki needed for correlation- or need to be correlated (from WLTP)Action TF to modify addendum of TA certificate // information doc (xx/2015 and 2007/46) By using characters ? (A, B, …, ZX??)

• The document has been separated into 3 documents– Test sheet– Test report– Recorded but no need to be kept

• « Test sheet » means kept by the OEM to be defined

– Content– How long will it be kept?

• Test Report – currently each TAA uses a different format. Agreed that having some form of harmonisation would be beneficial.

Reporting: work on test report AdminWG-38

Certificate (xx/2015) 2/2Current agreement / Text (xx/2015 addendum to appendix 4)


Vh and VL description Already included in the information document

Reference to other families (ATCT, RDE) ATCT correction already done- Copy all the results in CoC (Ki…)- Or have no reference to the detailed results

in CoC (because these are incorporated into the final result that is on the CoC)

RDE ? (need to consider in the numbering characters) A Jungk (BMW) and SS (Opel) are working on RDE columnRDL: information document

Approval Certification Numbering System: to be redefined?

Need a proposal on the « character » table (middle of 2016). To take into account:- Emission level- OBD- RDE (monitoring, step 1, step2) (see above)- Ki and Type 5 done in NEDC or WLTP- … ?- Pot pourri? // xx/2015 and 692/2008


FamiliesCurrent agreement / Text Proposal/agreement/comment

- Link between each family.- Ensure the reporting of the several tests

somewhere- Define

o when to carry out the tests, o how to apply the correction to the

results? Order of correction’s application Interference?

o sufficiency of information to provide a homologation’s certificate

RR for VH and VL in TVV family?

See previous references to families (information document, test results, certificate)


Extension rulesCurrent agreement / Text Proposal/agreement/comment

Need to decide how to deal with CO2 family and especially extrapolation rules (±3g within 30g or 20%)Need to decide if:- Keep the list as it is; or- Complement the list with other parameters;

or- Complement the list with a general

paragraph; or- Drop the list and just have the general

paragraph.

= energy demand on cycle = individual CO2/FC values

- checking and testing if needed

EC proposal on minimal data, access:- ‘transparency on technical information’

Action EC (KS) to circulate it and put in the agenda of the next AdminWG (updated) for discussion

Document provided 21/05/15 agreement in TA subgroup

2007/46: test resultsCurrent agreement / Text Proposal/agreement/comment

Which values to report? Linked to test report (xx/2015) Need to keep in mind the use of it:

- COP/ISC- National regulation demand (e.g.

German publication of pollutants’ emission)

- National registration

Annex VIII 2007/46:- Proposal: not to include pollutant emissions

results (see previous slides)- French proposal

(AdminWG42 - 100215 minutes) :• f0, f1, f2 for VL and VH• RR and Mass for VL and VH• Delta Cd.A of VL (compared to VH)

Agreed in the TF

2007/46: TVV 1/2Current agreement / Text Proposal/agreement/comment

Need to be redefinedWhat is a type? A variant? A version?Does it still exist?

See details :

Version definition (2007/46 annex II part B)Proposal:(k) for transition period, NEDC based EI to keep EI in the version definition ?(h), (i) and (j) “combined or weighted, combined xxx on NEDC” (where xxx is either CO2, or energy or fuel consumption) 692/2008 Article 2Proposal : remove (a)? NB: editorial note footnote (2) refers to the OJ if (a) is deleted the footnote will need to be moved to the next reference to Reg.83?EC proposal: Vehicle type regarding xx/2015 is defined by the interpolation familyAction ACEA to provide an alternative proposal for vehicle type definition regarding the xx/2015

2007/46: TVV 2/2Current agreement / Text Proposal/agreement/comment

Pollutant emissions VH and VL results?

Refer to emission level only : no actual results?

(see slide 12Action EC to consulte MS )

RDE refer to TVV (emissions data available) to be careful of redefining any T V or V


2007/46: CoCCurrent agreement / Text (annex IX 2007/46)


Transparency for customer: which level of informationCalculation by the OEM to be checked (see ‘individual vehicle’ slide 16)Option of Vind

Calculation of Cd.AMass = weighingRR

EC proposal (Action EC to provide for 29/05/15)CoC:- Today (NEDC)- NEDC and

WLTP (if available)- both values

(mandatory)- WLTP and

NEDC (if available)- WLTP only

Or- NEDC only

- NEDC if available and WLTP if available

- WLTP onlyThe less modification we have, the better it is (national registration, monitoring IT systems…)

Tyres combination (52. Remarks) Still revelant?


Open pointsCurrent agreement / Text Proposal/agreement/comment

Multistage vehicles Proposal ongoing on UNECE sideAction AR to answer:- How to approve multistage vehicles in WLTP?- What becomes of the DAM?

Combined approach for N-category vehicles Classes versus VH-VL definition

EC position: no problem to have different emissions limits (from different classes) and a interpolation between VL and VH for CO2/FC

Other categories of vehicles M2, N1 cl1, 2, 3 … Dates, masses…Action TF to work on it (character…?)

Smoke opacity Still relevant in the EU-WLTP? (no more reference to R24 in 582/2011 (Heavy Duty)xx/2015 may be needed for periodic inspection (regulation) Action KS to check with DG MOVE as to whether smoke requirements needs to be retained
