Division 6.2 Generation of the modified NEDC Speed Profile (mNEDC)

The speed profile of the mNEDC shall be generated according to the following rules:

• The test sequence is composed of an urban cycle made of four elementary urban cycles and an extra-urban cycle;

• All acceleration ramps are identical to the NEDC-profile;

• All constant speed levels are identical to the NEDC-profile;

• The deceleration values when coasting function is deactivated are equal to the ones within the NEDC-profile;

• The speed and time tolerances shall be in accordance with paragraph 1.4 of Annex 7 to UN/ECE Regulation No 101.

• The deviation from the NEDC profile shall be minimised and the overall distance must comply with the NEDC specified tolerances;

• The distance at the end of each deceleration phase of the mNEDC-profile shall be equal to the distances at the end of each deceleration phase of the NEDC-profile;

• For all phases of acceleration, constant velocity and deceleration, standard NEDC tolerances shall be applied.

• During coasting phases the ICE is decoupled and no active correction of the vehicles velocity trajectory is permitted.

• Lower speed limit for coasting v_min: The coasting mode has to be disabled at the lower speed limit (15 km/h) for coasting by pressing the brake pedal.

• Minimal stop time: The minimum time after every coasting deceleration to a standstill or constant speed phase is 2 seconds ( $t_{\mathrm{stop}}^{\min }$ in Figure 1).

• Minimum duration for constant speed phases: The minimum duration for constant speed phases after acceleration or coasting deceleration shall be at least 2 seconds ( $t_{\mathrm{const}}^{\min }$ in Figure 1).

• During the deceleration phases, the coasting mode can be enabled if the speed is below v_max, v_max being the maximum speed of the test cycle.

• The coasting mode may be disabled for speeds higher than v_min.
