2.2.    Identification of the WLTP test results to be used for the purpose of defining the input data for the simulation model

The input data for the correlation tool simulations shall be taken from the relevant WLTP test results for vehicle H and, where applicable, vehicle L as defined in accordance with point 4.2.1 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151. Where more than one WLTP type-approval test of vehicle H or L is performed in accordance with Table A6/2 of Annex XXI to that Regulation, the following test results shall be used for the purpose of determining the input data:

▼M1

▼M3

2.2a.   WLTP test conditions

In order for the WLTP test to be considered relevant in accordance with point 2.2 and for the purpose of determining the input data set out in point 2.4, the test conditions set out in Annex XXI to Regulation (EC) No 2017/1151 shall apply, with the following precisions:

▼M4

▼M3

With the approval of the approval authority or, where applicable, the technical service, the manufacturer may calculate the gear shifting points differently, provided that this is justified in view of the drivability of the vehicle, and that the additional power safety margin applied in accordance with point 3.4 of Sub-Annex 2 to Annex XXI to Regulation (EU) 2017/1151 does not exceed 20 %.

The conditions referred to in points (a) to (d) shall apply for the purpose of the correlation performed pursuant to this Regulation, and shall be without prejudice to the provisions laid down in Regulation (EU) 2017/1151 and to type approvals granted pursuant to that Regulation.

2.2b.   Applicability of the WLTP test conditions

The precisions referred to in point 2.2a.(a) to (d) shall apply in accordance with the following:

The confirmation shall indicate the interpolation family identifier, and the confirmation with regard to each of the test conditions referred to in points (a) to (d). The approval authority shall issue the confirmation to the manufacturer and shall ensure that the confirmation is recorded and can be made available without delay at the request of the Commission.

Where the approval authority cannot confirm that one or more of the test conditions referred to have been complied with, the manufacturer shall ensure that a new WLTP test, or, where applicable, test series, in accordance with Sub-Annex 6 to Annex XXI to Regulation (EU) 2017/1151 are performed under the supervision of an approval authority or, where applicable, technical service, applying the test conditions set out in point 2.2a.(a) to (d), for the interpolation family in question, including a new correlation in accordance with this Regulation.

The manufacturer may, in the case where only the test condition referred to in point 2.2a.(a) is not met, correct that value in the input matrix without the need for a new WLTP test.

The approval authority or, where applicable, the designated technical service shall record the results of the re-testing or correction and the correlation in accordance with paragraph 5 of Annex I, and the complete correlation file based on the re-testing in-put data shall be transmitted to the Commission in accordance with point 3.1.1.2 by 30 April 2021 at the latest.

▼B

2.3.    Determination of the input data and conditions for the operation of the correlation tool

The test conditions referred to in Annex XII to Regulation (EC) No 692/2008 shall be taken into account in the correlation tool simulations, including the precisions provided for in points 2.3.1 to 2.3.7 of this Annex.

The physical vehicle measurements referred to in point 3 shall be performed in accordance with the conditions referred to in that Regulation, with the precisions given in this Annex, and, where applicable, the input data defined in point 2.4.

▼M1

2.3.1.    Determination of the NEDC vehicle inertia

The NEDC reference mass of vehicles H and, where applicable, of vehicles L and R shall be determined as follows:

Where,

Vehicle R is the representative vehicle of the Road Load Matrix Family as defined in point 5.1 of Sub-Annex 4 to Annex XXI to Commission Regulation (EU) 2017/1151 ( 6 );

▼M2

MRO is the mass in running order as defined in Article 3(1)(d) of Regulation (EC) No 443/2009 for vehicles H, L and R respectively.

▼M1

The reference mass to be used as input for the simulations and, where applicable, for a physical vehicle test shall be the inertia value set out in Table 3 of Annex 4a to UN/ECE Regulation No 83 which is equivalent to the reference mass, RM, determined in accordance with this point and referred to as TMn,L, TMn,H and TMn,R.

▼B

2.3.2.    Determination of the pre-conditioning effect

In preparing the chassis-dynamometer for the execution of a type-approval test, the vehicle is pre-conditioned in order to reach similar conditions to those used in the coast-down test. The pre-conditioning procedure used in the WLTP test differs from that used for the purpose of NEDC so that, with equal road loads, the vehicle is considered subject to higher forces under the WLTP. That difference shall be set at 6 Newton and that value shall be used for the calculation of the NEDC road loads in accordance with point 2.3.8.

2.3.3.    Ambient conditions referred to in point 3.1.1 of UN/ECE Regulation No 83

For the purpose of the correlation tool, the test cell temperature shall be set at 25 °C.

Also in the case of a physical vehicle measurement pursuant to point 3, the test cell temperature shall be set at 25 °C. However, on request by the manufacturer, the test cell temperature may be set at a value between 20 to 25 °C for the physical measurement.

2.3.4.    Determination of the initial battery state of charge

The initial battery state of charge shall be set to at least 99 per cent for the purpose of the correlation tool test. The same shall apply in the case of a physical vehicle test.

▼M1

2.3.5.    Determination of the difference in tyre pressure prescriptions

According to point 6.6.3 of Appendix 3 to Annex I to Regulation (EU) 2017/1151, the lowest recommended tyre pressure for the vehicle test mass shall be used during the coast down for the road load determination, while this is not specified in the NEDC. The tyre pressure to be taken into account for the purpose of calculating the NEDC road load in accordance with point 2.3.8 shall be the average between the two axles of the average between the minimum and maximum tyre pressure permitted for the selected tyres on each axle for the NEDC reference mass of the vehicle. The calculation shall be carried out for vehicle H and, where applicable, for vehicles L and R with the following formulae:

Where,

Pmax,

is the average of the maximum tyre pressures of the selected tyres for the two axles;

Pmin,

is the average of the minimum tyre pressures of the selected tyres for the two axles.

The corresponding effect in terms of resistance applied to the vehicle shall be calculated using the following formulae for vehicles H, L and R:

2.3.6.    Determination of the tyre tread depth (TTD)

According to point 4.2.2.2 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151 the minimum tyre tread depth is 80 % for the WLTP test, while pursuant to point 4.2 of Appendix 7 to Annex 4a to UN/ECE Regulation No 83, the minimum allowed tyre tread depth for the purpose of the NEDC test is 50 % of the nominal value. That results in an average difference of 2 mm in tread depth between the two procedures. The corresponding effect in terms of the resistance applied to the vehicle shall be determined for the purpose of the NEDC road load calculation in point 2.3.8 in accordance with the following formulae for vehicles H, L and R:

Where,

RMn,H, RMn,L, and RMn,R are the reference masses of vehicles H, L and R determined in accordance with point 2.3.1.

▼B

2.3.7.    Determination of the inertia of rotating parts

For the purpose of the correlation tool:

During the simulation of the WLTP test four rotating wheels are to be considered, while for the purpose of the NEDC tests only two rotating wheels are to be considered. The effect this has on the forces applied to the vehicle shall be taken into account in accordance with the formulae set out in point 2.3.8.1.1(a)(3).

The acceleration and deceleration forces in the correlation tool shall be calculated for the NEDC simulation by considering the inertia of only two rotating wheels.

For the purpose of a physical test:

During the WLTP coastdown setting, coastdown times are to be transferred to forces and vice versa by taking into account the applicable test mass plus the effect of rotational mass (3 % of the sum of the MRO and 25 kg). For the NEDC coastdown setting, coastdown times are to be transferred to forces and vice versa by neglecting the effect of rotational mass (only NEDC vehicle inertia calculated in point 2.3.1 is used).

2.3.8.    Determination of the NEDC road loads

▼M2

2.3.8.1.   In the case of WLTP road loads being determined in accordance with paragraphs 1-4 and 6 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151

The NEDC road load coefficients shall be calculated in accordance with the formulae specified in point 2.3.8.1.1. (for vehicle H) and in point 2.3.8.1.2. (for vehicle L) and with the following points (a) and (b).

Unless otherwise specified the formulae shall apply both in the case of simulations and in the case of physical vehicle tests.

The type approval authority or, where applicable, the technical service shall verify if the wind-tunnel facility referred to in paragraph 3.2.3.2.2.3. in Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151 is qualified to accurately determine the Δ(Cd × Af) values. If the wind-tunnel facility is not qualified, the highest aerodynamic drag value shall apply for all vehicles in the family.

The choice of the procedure set out in points (i) or (ii) shall be made by the manufacturer.

Point (b) shall apply for new emissions type approvals granted from 1 January 2019, or from an earlier date at the manufacturer's request.

▼B
