Division 4.2.3 Utility factor-weighted fuel consumption for OVC-HEVs

The utility factor-weighted fuel consumption from the charge-depleting and charge-sustaining Type 1 test shall be calculated using the following equation:

where:

F1In the case that the interpolation method is applied, k shall be the number of phases driven up to the end of the transition cycle of vehicle L n_{veh_L}.

If the transition cycle number driven by vehicle H, $n_{{\mathrm{veh}}_H}$, and, if applicable, by an individual vehicle within the vehicle interpolation family $n_{{\mathrm{veh}}_{\mathrm{ind}}}$ is lower than the transition cycle number driven by vehicle L, n_{veh_L}, the confirmation cycle of vehicle H and, if applicable, an individual vehicle shall be included in the calculation.

F2The fuel consumption of each phase of the confirmation cycle shall be calculated in accordance with paragraph 6. of Sub-Annex 7 with the criteria emission over the complete confirmation cycle and the applicable CO₂ phase value which shall be corrected to an electric energy consumption of zero EC_DC,CD,j = 0 by using the CO₂ mass correction coefficient (K_CO2) in accordance with Appendix 2 to this Sub-Annex.
