COMMISSION REGULATION (EU) 2016/646

of 20 April 2016

amending Regulation (EC) No 692/2008 as regards emissions from light passenger and commercial vehicles (Euro 6)

(Text with EEA relevance)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Regulation (EC) No 715/2007 of the European Parliament and of the Council of 20 June 2007 on type-approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair and maintenance information (1), and in particular Article 5(3) thereof,

Whereas:

| (1) | Regulation (EC) No 715/2007 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC of the European Parliament and of the Council (2). |
| --- | --- |

(1)

Regulation (EC) No 715/2007 is one of the separate regulatory acts under the type-approval procedure laid down by Directive 2007/46/EC of the European Parliament and of the Council (2).

| (2) | Regulation (EC) No 715/2007 requires new light-duty vehicles to comply with certain emission limits and lays down additional requirements on access to information. The specific technical provisions necessary to implement that Regulation were adopted by Commission Regulation (EC) No 692/2008 (3). |
| --- | --- |

(2)

Regulation (EC) No 715/2007 requires new light-duty vehicles to comply with certain emission limits and lays down additional requirements on access to information. The specific technical provisions necessary to implement that Regulation were adopted by Commission Regulation (EC) No 692/2008 (3).

| (3) | The Commission has performed a detailed analysis of the procedures, tests and requirements for type-approval that are set out in Regulation (EC) No 692/2008 on the basis of own research and external information and found that emissions generated by real driving of Euro 5/6 vehicles on the road substantially exceed the emissions measured on the regulatory new European driving cycle (NEDC), in particular with respect to NOx emissions of diesel vehicles. |
| --- | --- |

(3)

The Commission has performed a detailed analysis of the procedures, tests and requirements for type-approval that are set out in Regulation (EC) No 692/2008 on the basis of own research and external information and found that emissions generated by real driving of Euro 5/6 vehicles on the road substantially exceed the emissions measured on the regulatory new European driving cycle (NEDC), in particular with respect to NOx emissions of diesel vehicles.

| (4) | The type-approval emission requirements for motor vehicles have been gradually and significantly tightened through the introduction and subsequent revision of Euro standards. While vehicles in general have delivered substantial emission reductions across the range of regulated pollutants, this was not the case for NOx emissions from diesel engines, in particular light-duty vehicles. Actions for correcting this situation are therefore needed. |

The type-approval emission requirements for motor vehicles have been gradually and significantly tightened through the introduction and subsequent revision of Euro standards. While vehicles in general have delivered substantial emission reductions across the range of regulated pollutants, this was not the case for NOx emissions from diesel engines, in particular light-duty vehicles. Actions for correcting this situation are therefore needed.

| (5) | ‘Defeat devices’ as defined in Article 3(10) of Regulation (EC) No 715/2007 reducing the level of emission control are prohibited. Recent events have highlighted the need to strengthen the enforcement in this respect. Therefore it is appropriate to require a better supervision of the emission control strategy applied by the manufacturer at type-approval, following the principles already applied to heavy-duty vehicles by Euro VI Regulation (EC) No 595/2009 and its implementing measures. |

| (6) | Addressing the problem of NOx emissions from diesel vehicles should contribute to decreasing the current sustained high levels of NO2 concentrations in ambient air, which are a major concern regarding human health. |

Addressing the problem of NOx emissions from diesel vehicles should contribute to decreasing the current sustained high levels of NO2 concentrations in ambient air, which are a major concern regarding human health.

| (7) | The Commission has established in January 2011 a working group involving all interested stakeholders for developing a real driving emission (RDE) test procedure better reflecting emissions measured on the road. For this purpose, and after thorough technical discussions, the option suggested in Regulation (EC) No 715/2007, i.e. the use of portable emission measurement systems (PEMS) and not-to-exceed (NTE) limits, has been followed. |

| (8) | As agreed with stakeholders in the CARS 2020 process (4), the RDE test procedures should be introduced in two phases: during a first transitional period the test procedures should only be applied for monitoring purposes, while afterwards they should be applied together with binding quantitative RDE requirements to all new type-approvals and new vehicles. |

| (9) | The RDE test procedures were introduced by Commission Regulation (EU) 2016/427 (5). It is now necessary to establish the quantitative RDE requirements in order to limit tailpipe emissions under all normal conditions of use pursuant to the emission limits set out in Regulation (EC) No 715/2007. For that purpose, statistical and technical uncertainties of the measurement procedures should be taken into account. |

For that purpose, statistical and technical uncertainties of the measurement procedures should be taken into account.

| (10) | In order to allow manufacturers to gradually adapt to the RDE rules, the final quantitative RDE requirements should be introduced in two subsequent steps. In the first step, which should start applying 4 years after the dates of mandatory application of the Euro 6 standards, a conformity factor of 2,1 should apply. The second step should follow 1 year and 4 months after the first step and should require full compliance with the emission limit value for NOx of 80 mg/km set out in Regulation (EC) No 715/2007 plus a margin taking into account the additional measurement uncertainties related to the application of portable emission measurement systems (PEMS). |

| (11) | While it is important that all possible driving situations are potentially covered by RDE testing, it should be avoided that the tested vehicles are driven in a biased manner, i.e. with the intention to generate a passed or failed test not by virtue of the technical performance of the vehicle but due to extreme driving patterns. Therefore, complementary boundary conditions for RDE testing are introduced in order to address such situations. |

Therefore, complementary boundary conditions for RDE testing are introduced in order to address such situations.

| (12) | Due to their very nature, driving conditions encountered during individual PEMS trips may not fully correspond to ‘normal conditions of use of a vehicle’. The severity of emission control during such trips may therefore vary. As a consequence, and in order to take into account the statistical and technical uncertainties of the measurement procedures, it may be considered in the future to reflect in the NTE emission limits applicable to individual PEMS trips the characteristics of those trips, described by certain measurable parameters, e.g. related to the driving dynamics or workload. If that principle is applied, it should not lead to the weakening of the environmental effect and the effectiveness of the RDE test procedures, which should be demonstrated by a peer-reviewed scientific study. In addition, for the assessment of the severity of emission control during a PEMS trip, only parameters that can be justified by objective scientific reasons and not just by reasons of calibration of the engine or the pollutant control devices or the emission control systems should be taken into account. |

| (13) | Finally, recognising the need to control NOx emissions in urban conditions, urgent consideration shall be given to changing the relative weighting of the urban, rural and motorway elements of the RDE test to ensure a low conformity factor can be achieved in practice, creating a further boundary condition relating to driving dynamics in the third regulatory RDE package above which the extended conditions shall be applicable from the step 1 introduction dates. |

3.   TRIP INDICATORS

3.1.   Calculations

3.1.1.   Data pre-processing

Dynamic parameters like acceleration, v · apos
  or RPA shall be determined with a speed signal of an accuracy of 0,1 % above 3 km/h and a sampling frequency of 1 Hz. This accuracy requirement is generally fulfilled by wheel (rotational) speed signals.

The speed trace shall be checked for faulty or implausible sections. The vehicle speed trace of such sections is characterised by steps, jumps, terraced speed traces or missing values. Short faulty sections shall be corrected, for example by data interpolation or benchmarking against a secondary speed signal. Alternatively, short trips containing faulty sections could be excluded from the subsequent data analysis. In a second step the acceleration values shall be ranked in ascending order, in order to determine the acceleration resolution ares
  = (minimum acceleration value > 0).

If ares
  ≤ 0,01 m/s
  2, the vehicle speed measurement is accurate enough.

If 0,01 < ares ≤ rmax m/s2, smoothing by using a T4253 Hanning filter.

If ares > rmax m/s2, the trip is invalid.

The T4253 Hanning filter performs the following calculations: The smoother starts with a running median of 4, which is centred by a running median of 2. It then re-smoothes these values by applying a running median of 5, a running median of 3, and Hanning (running weighted averages). Residuals are computed by subtracting the smoothed series from the original series. This whole process is then repeated on the computed residuals. Finally, the smoothed residuals are computed by subtracting the smoothed values obtained the first time through the process.

The correct speed trace builds the basis for further calculations and binning as described in paragraph 3.1.2.

3.1.2.   Calculation of distance, acceleration and v · a

The following calculations shall be performed over the whole time-based speed trace (1 Hz resolution) from second 1 to second tt
  (last second).

The distance increment per data sample shall be calculated as follows:

di
  = vi
  /3,6, i = 1 to
  Nt

Where:

| di is the distance covered in time step i [m] |
| --- |

di is the distance covered in time step i [m]

| v
  i is the actual vehicle speed in time step i [km/h] |
| --- |

v
  i is the actual vehicle speed in time step i [km/h]

| N
  t is the total number of samples |
| --- |

N
  t is the total number of samples

The acceleration shall be calculated as follows:

ai
  = (v

  i + 1 – v

  i – 1)/(2 · 3,6), i = 1 to
  Nt

Where:

ai
  is the acceleration in time step i [m/s2]. For i = 1: vi – 1 = 0, for i = Nt
  : vi + 1 = 0.

The product of vehicle speed per acceleration shall be calculated as follows:

(v · a)i
  = vi
  · ai
  /3,6, i = 1 to
  Nt

Where:

(v · a)i
  is the product of the actual vehicle speed per acceleration in time step i [m2/s3 or W/kg].

3.1.3.   Binning of the results

After the calculation of ai
  and (v · a)i
  , the values vi
  , di
  , ai
  and (v · a)i
  shall be ranked in ascending order of the vehicle speed.

All datasets with vi
  ≤ 60 km/h belong to the ‘urban’ speed bin, all datasets with 60 km/h < vi
  ≤ 90 km/h belong to the ‘rural’ speed bin and all datasets with vi
  > 90 km/h belong to the ‘motorway’ speed bin.

The number of datasets with acceleration values ai
  > 0,1 m/s2 shall be bigger or equal to 150 in each speed bin.

For each speed bin the average vehicle speed
  Formula
  shall be calculated as follows:

Formula
  , i = 1 to
  Nk,k = u,r,m

Where:

Nk
  is the total number of samples of the urban, rural, and motorway shares.

3.1.4.   Calculation of v · apos_[95] per speed bin

The 95th percentile of the v · apos
  values shall be calculated as follows:

The (v · a)i,k
  values in each speed bin shall be ranked in ascending order for all datasets with ai,k
  ≥ 0,1 m/s
  2 and the total number of these samples Mk
  shall be determined.

Percentile values are then assigned to the (v · apos)j,k
  values with ai,k
  ≥ 0,1 m/s
  2 as follows:

The lowest v · apos
  value gets the percentile 1/Mk
  , the second lowest 2/Mk
  , the third lowest 3/Mk
  and the highest value Mk/Mk
  =100 %.

(v · apos)k
  _[95] is the (v · apos)j,k
  value, with j/Mk
  = 95 %. If j/Mk
  = 95 % cannot be met, (v · apos)k
  _[95] shall be calculated by linear interpolation between consecutive samples j and j + 1 with j/Mk
  < 95 % and (j + 1)/Mk
  > 95 %.

The relative positive acceleration per speed bin shall be calculated as follows:

RPAk
  = Σ
  j
  (Δt · (v · apos
  )
  j,k
  )/Σ
  idi,k
  , j = 1 to
  Mk,i = 1 to
  Nk,k = u,r,m

Where:

RPAk is the relative positive acceleration for urban, rural and motorway shares in [m/s2 or kWs/(kg*km)]

| Δt | time difference equal to 1 second |
| --- | --- |
| Mk | the sample number for urban, rural and motorway shares with positive acceleration |

  [km/h] recorded at a frequency of 1 Hz and the corresponding time t [s] that has passed since test start.

4.   CALCULATION OF CUMULATIVE POSITIVE ELEVATION GAIN

4.1.   General

The cumulative positive elevation gain of an RDE trip shall be calculated as a three-step procedure, consisting of: (i) the screening and principle verification of data quality; (ii) the correction of instantaneous vehicle altitude data; and (iii) the calculation of the cumulative positive elevation gain.

4.2.   Screening and principle verification of data quality

The instantaneous vehicle speed data shall be checked for completeness. Correcting for missing data is permitted if gaps remain within the requirements specified in Point 7 of Appendix 4; else, the test results shall be voided. The instantaneous altitude data shall be checked for completeness. Data gaps shall be completed by data interpolation. The correctness of interpolated data shall be verified by a topographic map. It is recommended to correct interpolated data if the following condition applies:

|hGPS(t) – hmap(t)| > 40 m

The altitude correction shall be applied so that:

h(t) = hmap(t)

where:

| h(t) | — | vehicle altitude after the screening and principle verification of data quality at data point t [m above sea level] |
| --- | --- | --- |
| hGPS(t) | — | vehicle altitude measured with GPS at data point t [m above sea level] |
| hmap(t) | — | vehicle altitude based on topographic map at data point t [m above sea level]. |

hGPS(t)

—

vehicle altitude measured with GPS at data point t [m above sea level]

4.3.   Correction of instantaneous vehicle altitude data

The altitude h(0) at the start of a trip at d(0) shall be obtained by GPS and verified for correctness with information from a topographic map. The deviation shall not be larger than 40 m. Any instantaneous altitude data h(t) shall be corrected if the following condition applies:

|h(t) – h(t – 1)| > (v(t)/3,6 * sin45°)

The altitude correction shall be applied so that:

hcorr(t) = hcorr
  (t-1)

where:

| h(t) | — | vehicle altitude after the screening and principle verification of data quality at data point t [m above sea level] |
| --- | --- | --- |
| h(t-1) | — | vehicle altitude after the screening and principle verification of data quality at data point t-1 [m above sea level] |
| v(t) | — | vehicle speed of data point t [km/h] |
| hcorr(t) | — | corrected instantaneous vehicle altitude at data point t [m above sea level] |
| hcorr(t-1) | — | corrected instantaneous vehicle altitude at data point t-1 [m above sea level]. |

h(t)

—

vehicle altitude after the screening and principle verification of data quality at data point t [m above sea level]

Upon the completion of the correction procedure, a valid set of altitude data is established. This data set shall be used for the final calculation of the cumulative positive elevation gain as described in point 4.4.

4.4.   Final calculation of the cumulative positive elevation gain

4.4.1.   Establishment of a uniform spatial resolution

The total distance dtot
  [m] covered by a trip shall be determined as sum of the instantaneous distances di
  . The instantaneous distance di
  shall be determined as:

4.4.3.   Calculation of the final result

The positive cumulative elevation gain of a trip shall be calculated by integrating all positive interpolated and smoothed road grades, i.e. roadgrade,2(d). The result should be normalised by the total test distance dtot
  and expressed in meters of cumulative elevation gain per 100 kilometres of distance.

5.   NUMERICAL EXAMPLE

Tables 1 and 2 show the steps performed in order to calculate the positive elevation gain on the basis of data recorded during an on-road test performed with PEMS. For the sake of brevity an extract of 800 m and 160 s is presented here.

5.1.   Screening and principle verification of data quality

The screening and principle verification of data quality consists of two steps. First, the completeness of vehicle speed data is checked. No data gaps related to vehicle speed are detected in the present data sample (see Table 1). Second, the altitude data are checked for completeness; in the data sample, altitude data related to seconds 2 and 3 are missing. The gaps are filled by interpolating the GPS signal. In addition, the GPS altitude is verified by a topographic map; this verification includes the altitude h(0) at the start of the trip. Altitude data related to seconds 112-114 are corrected on the basis of the topographic map to satisfy the following condition:

hGPS(t) – hmap(t) < – 40 m

As result of the applied data verification, the data in the fifth column h(t) are obtained.

5.2.   Correction of instantaneous vehicle altitude data

As a next step, the altitude data h(t) of seconds 1 to 4, 111 to 112 and 159 to 160 are corrected assuming the altitude values of seconds 0, 110 and 158 respectively since the following condition applies:

|h(t) – h(t – 1)| > (v(t)/3,6 * sin45°)

As result of the applied data correction, the data in the sixth column hcorr(t) are obtained. The effect of the applied verification and correction steps on the altitude data is depicted in Figure 2.

5.3.   Calculation of the cumulative positive elevation gain

5.3.1.   Establishment of a uniform spatial resolution

The instantaneous distance di
  is calculated by dividing the instantaneous vehicle speed measured in km/h by 3,6 (Column 7 in Table 1). Recalculating the altitude data to obtain a uniform spatial resolution of 1 m yields the discrete way points d (Column 1 in Table 2) and their corresponding altitude values hint(d) (Column 7 in Table 2). The altitude of each discrete way point d is calculated through interpolation of the measured instantaneous altitude hcorr
  as:

Formula

Formula

5.3.2.   Additional data smoothing

In Table 2, the first and last discrete way points are: da
   = 0 m and de
   = 799 m, respectively. The altitude data of each discrete way point is smoothed by applying a two-step procedure. The first smoothing run consists of:

Formula

chosen to demonstrate the smoothing for d ≤ 200 m

Formula

chosen to demonstrate the smoothing for 200 m < d < (599 m)

Formula

chosen to demonstrate the smoothing for d ≥ (599 m)

The smoothed and interpolated altitude is calculated as:

h

  int,sm,1(0) = hint
  (0) + road

  grade,1(0) = 120,3 + 0,0033 ≈ 120,3033 m

h

  int,sm,1(799) = h

  int,sm,1(798) + road

  grade,1(799) = 121,2550 – 0,0220 = 121,2330 m

Second smoothing run:

Formula

chosen to demonstrate the smoothing for d ≤ 200 m

Formula

chosen to demonstrate the smoothing for 200 m < d < (599 m)

Formula

chosen to demonstrate the smoothing for d ≥ (599 m)

5.3.3.   Calculation of the final result

The positive cumulative elevation gain of a trip is calculated by integrating all positive interpolated and smoothed road grades, i.e. roadgrade,2(d). For the presented example the total covered distance was dtot
   = 139,7 km and all positive interpolated and smoothed road grades were of 516 m. Therefore a positive cumulative elevation gain of 516 × 100/139,7 = 370 m/100 km was achieved.
