Appendix 9

Explanatory note on the gearshift procedure for a type I test

0.

Introduction

This explanatory note explains matters specified or described in this Regulation, including its Annexes or Appendices, and matters related thereto with regard to the gearshift procedure.

1.

Approach

  • 1.1.The development of the gearshift procedure was based on an analysis of the gearshift points in the in-use data. In order to establish generalised correlations between technical specifications of the vehicles and gearshift speeds, the engine speeds were normalised to the utilisable band between rated speed and idling speed.
  • 1.2.In a second step, the end speeds (vehicle speed as well as normalised engine speed) for upshifts and downshifts were determined and recorded in a separate table. The averages of these speeds for each gear and vehicle were calculated and correlated with the vehicles’ technical specifications.
  • 1.3.The results of these analyses and calculations can be summarised as follows:
  • (a) the gearshift behaviour is engine-speed-related rather than vehicle-speed-related;
  • (b) the best correlation between gearshift speeds and technical data was found for normalised engine speeds and the power-to-mass ratio (maximum continuous rated power/(mass in running order + 75 kg));
  • (c) the residual variations cannot be explained by other technical data or by different drive train ratios. They are most probably due to differences in traffic conditions and individual driver behaviour;
  • (d) the best approximation between gearshift speeds and power-to-mass ratio was found for exponential functions;
  • (e) the gearshift mathematical function for the first gear is significantly lower than for all other gears;
  • (f) the gearshift speeds for all other gears can be approximated by one common mathematical function;
  • (g) no differences were found between five-speed and six-speed gearboxes;
  • (h) gearshift behaviour in Japan is significantly different from the equal-type gearshift behaviour in the European Union (EU) and in the United States of America (USA).
  • 1.4.In order to find a balanced compromise between the three regions, a new approximation function for normalised upshift speeds versus power-to-mass ratio was calculated as a weighted average of the EU/USA curve (with 2/3 weighting) and the Japanese curve (with 1/3 weighting), resulting in the following equations for normalised engine upshift speeds:

Equation Ap9-1: Normalised upshift speed in 1st gear (gear 1)

Equation Ap9-2: Normalised upshift speed in gears > 1

Image omitted; see official source

2.

Calculation example

  • 2.1 Figure Ap 9-1 shows an example of gearshift use for a small vehicle:
  • (a) the lines in bold show the gear use for acceleration phases;
  • (b) the dotted lines show the downshift points for deceleration phases;
  • (c) in the cruising phases, the whole speed range between downshift speed and upshift speed may be used.
  • 2.2 Where vehicle speed increases gradually during cruise phases, upshift speeds (v1—2, v2—3and vi—i+1) in km/h may be calculated using the following equations:

Equation Ap9-3:

In order to allow the technical service more flexibility and to ensure driveability, the gearshift regression functions should be considered as lower limits. Higher engine speeds are permitted in any cycle phase.

3.

Phase indicators

  • 3.1 In order to avoid different interpretations in the application of the gearshift equations and thus to improve the comparability of the test, fixed-phase indicators are assigned to the speed pattern of the cycles. The specification of the phase indicators is based on the definition from the Japan Automobile Research Institute (JARI) of the four driving modes as shown in the following table:

Table Ap9-1

Definition of driving modes

4 modes Definition
Idle mode vehicle speed < 5 km/h and -0,5 km/h/s (-0,139 m/s2) < acceleration < 0,5 km/h/s (0,139 m/s2)
Acceleration mode acceleration > 0,5 km/h/s (0,139 m/s2)
Deceleration mode acceleration < - 0,5 km/h/s (- 0,139 m/s2)
Cruise mode vehicle speed ≥ 5 km/h and -0,5 km/h/s (-0,139 m/s2) < acceleration < 0,5 km/h/s (0,139 m/s2)
  • 3.2 The indicators were then modified in order to avoid frequent changes during relatively homogeneous cycle parts and thus improve driveability. Figure Ap9-2 shows an example from cycle part 1.

Calculation example

  • 4.1.An example of input data necessary for the calculation of shift speeds is shown in Table Ap 9-2. The upshift speeds for acceleration phases for first gear and higher gears are calculated using Equations 9-1 and 9-2. The denormalisation of engine speeds can be performed using the equation

Image omitted; see official source .

  • 4.2.The downshift speeds for deceleration phases can be calculated using Equations 9-3 and 9-4. The ndv values in Table Ap 9-2 can be used as gear ratios. These values can also be used to calculate the corresponding vehicle speeds (

Image omitted; see official source . The results are shown in Tables Ap9-3 and Ap9-4.

  • 4.3.Additional analyses and calculations were conducted to investigate whether these gearshift algorithms could be simplified and, in particular, whether engine shift speeds could be replaced by vehicle shift speeds. The analysis showed that vehicle speeds could not be brought in line with the gearshift behaviour of the in-use data.

  • 2.2.4. At the manufacturer’s request, the type I test may be performed on both reference fuels, so that no correction is needed.
  • 2.2.5. The parent vehicle shall comply with the emission limits for the relevant category set out in Annex VI(A) to Regulation (EU) No 168/2013 and for both measured and calculated emissions.

- 2.2.6. If repeated tests are conducted on the same engine, an average shall first be taken of the results on reference fuel G20, or A, and those on reference fuel G25, or B; the ‘r’ factor shall then be calculated from these averages.

- 2.2.7. For the type-approval of a flex fuel H2NG vehicle as a member of a family, two type I tests shall be performed, the first test with 100 % of either G20 or G25, and the second test with the mixture of hydrogen and the same NG/biomethane fuel used during the first test, with the maximum hydrogen percentage specified by the manufacturer.

Appendix 13

Type I test procedure for L-category vehicles equipped with a periodically regenerating system

1.

Introduction

This Appendix contains specific provisions regarding the type-approval of vehicles equipped with a periodically regenerating system.

2.

Scope of the type-approval for vehicles with a periodically regenerating system as regards type I tests

- 2.1. L-category vehicles falling within the scope of Regulation (EU) No 168/2013 that are equipped with periodically regenerating systems shall comply with the requirements in this Appendix.

  • 2.2. Instead of carrying out the test procedures in the following point, a fixed Ki value of 1,05 may be used if the technical service sees no reason why this value could be exceeded and after approval of the approval authority.
  • 2.3. During cycles where regeneration occurs, emission standards can be exceeded. If a regeneration of an anti-pollution device occurs at least once per Type I test and that has already regenerated at least once during the vehicle preparation cycle, it will be considered as a continuously regenerating system which does not require a special test procedure.
3.

Test procedure

The vehicle may be equipped with a switch capable of preventing or permitting the regeneration process provided that its operation has no effect on original engine calibration. This switch shall be used for the purpose of preventing regeneration only during loading of the regeneration system and during the pre-conditioning cycles. However, it shall not be used during the measurement of emissions in the regeneration phase; rather, the emission test shall be carried out with the unchanged original equipment manufacturer’s powertrain control unit / engine control unit / drive train control unit if applicable and powertrain software.

  • 3.1. Measurement of carbon dioxide emission and fuel consumption between two cycles where regenerative phases occur.
  • 3.1.1. The average of carbon dioxide emission and fuel consumption between regeneration phases and during loading of the regenerative device shall be determined from the arithmetic mean of several approximately equidistant (if more than two) type I operating cycles.

As an alternative, the manufacturer may provide data to show that carbon dioxide emissions and fuel consumption remain constant (+4 percent) between regeneration phases. In this case, the carbon dioxide emissions and fuel consumption measured during the regular type I test may be used. In any other case, emissions shall be measured for at least two type I operating cycles: one immediately after regeneration (before new loading) and one as immediately as possible before a regeneration phase. All emissions measurements and calculations shall be carried out in accordance with Annex II. Average emissions for a single regenerative system shall be determined in accordance with point 3.3 and for multiple regeneration systems in accordance with point 3.4.

  • 3.1.2. The loading process and Ki determination shall be carried out on a chassis dynamometer during the type I operating cycles. These cycles may be run continuously (i.e. without the need to switch the engine off between cycles). After any number of completed cycles, the vehicle may be removed from the chassis dynamometer and the test continued at a later time.
  • 3.1.3. The number of cycles (D) between two cycles in which regeneration phases occur, the number of cycles over which emissions measurements are taken (n) and each emissions measurement (M’sij) shall be reported according to the template of the test report referred to in Article 32(1) of Regulation (EU0 No 168/2013.
  • 3.2. Measurement of carbon dioxide emissions and fuel consumption during regeneration
  • 3.2.1. If necessary, the vehicle may be prepared for the emissions test during a regeneration phase using the preparation cycles in Appendix 6.
  • 3.2.2. The test and vehicle conditions for the type I test described in Annex II apply before the first valid emission test is carried out.
  • 3.2.3. Regeneration shall not occur during the preparation of the vehicle. This may be ensured by one of the following methods:
  • 3.2.3.1. a ‘dummy’ regenerating system or partial system may be fitted for the pre-conditioning cycles;
  • 3.2.3.2. any other method agreed between the manufacturer and the approval authority.
  • 3.2.4. A cold-start exhaust emission test including a regeneration process shall be carried out in accordance with the applicable type I operating cycle.
  • 3.2.5. If the regeneration process requires more than one operating cycle, subsequent test cycle(s) shall be driven immediately, without switching the engine off, until complete regeneration has been achieved (each cycle shall be completed). The time necessary to set up a new test shall be as short as possible (e.g. as required to change a particulate matter filter on the analysing equipment). The engine shall be switched off during this period.
  • 3.2.6. The emission values, including pollutant and carbon dioxide emission values, and fuel consumption during regeneration (Mri) shall be calculated in accordance with Annex II and point 3.3. The number of operating cycles (d) measured for complete regeneration shall be recorded.
  • 3.3. Calculation of the combined exhaust emissions of a single regenerative system:
