The downscaling shall be applied first to the time period between second 1520 and second 1725.
Second 1725 is the time when the maximum speed of the extra high speed phase is reached.
The down­ scaled speed trace shall be subsequently calculated using the following equation:
vdsciþ1 1⁄4 vdsci þ aorigi Ü ð1 Ä fdsc Þ Ü 3:6 for i = 1520 to 1724.
For i = 1520, vdsci = vorigi.
In order to meet the original vehicle speed at second 1743, a correction factor for the deceleration shall be calculated using the following equation:
fcorr_dec ¼
vdsc_1725 Ä 90:4 vorig_1725 Ä 90:4
90.4 km/h is the original vehicle speed at second 1743.
The downscaled vehicle speed between second 1726 and second 1742 shall be calculated using the following equation: vdsciþ1 1⁄4 vdsciÄ1 þ aorigiÄ1 Ü fcorr_dec Ü 3:6 for i = 1726 to 1742.

Downscaling procedure for Class 3 cycles This paragraph is only applicable for Level 1A; Figure A1/16 shows an example for a downscaled extra high speed phase of the Class 3 WLTC.
