  "heading": "Generation of the modified NEDC Speed Profile (mNEDC)",
  "text": "The speed profile of the mNEDC shall be generated according to the following rules:\nThe test sequence is composed of an urban cycle made of four elementary urban cycles and an extra-urban cycle;\nAll acceleration ramps are identical to the NEDC-profile;\nAll constant speed levels are identical to the NEDC-profile;\nThe deceleration values when coasting function is deactivated are equal to the ones within the NEDC-profile;\nThe speed and time tolerances shall be in accordance with paragraph 1.4 of Annex 7 to UN/ECE Regulation No 101.\nThe deviation from the NEDC profile shall be minimised and the overall distance must comply with the NEDC specified tolerances;\nThe 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;\nFor all phases of acceleration, constant velocity and deceleration, standard NEDC tolerances shall be applied.\nDuring coasting phases the ICE is decoupled and no active correction of the vehicles velocity trajectory is permitted.\nLower speed limit for coasting vmin: The coasting mode has to be disabled at the lower speed limit (15 km/h) for coasting by pressing the brake pedal.\nMinimal stop time: The minimum time after every coasting deceleration to a standstill or constant speed phase is 2 seconds ( t stop min in Figure 1).\nMinimum duration for constant speed phases: The minimum duration for constant speed phases after acceleration or coasting deceleration shall be at least 2 seconds ( t const min in Figure 1).\nDuring the deceleration phases, the coasting mode can be enabled if the speed is below vmax, vmax being the maximum speed of the test cycle.\nThe coasting mode may be disabled for speeds higher than vmin.",
