The average RCB corrected CO2 emissions (g/km) for each phase of the applicable WLTC shall be expressed in units g/s using the following equation:
MCO2;j ¼ MCO2;RCB;j Ü
dm;j tj
where:
3.6.
MCO2,j
is the average CO2 emission of phase j, g/s;
MCO2,RCB,j
is the CO2 emission from step 1 of Table A7/1 of Annex B7 for the considered WLTC phase j corrected in accordance with Appendix 2 to Annex B6, and with the requirement of applying the RCB correction;
dm,j
is the actually driven distance of the considered phase j, km;
tj
is the duration of considered phase j, s.
In the next step these CO2 emissions (g/s) for each phase of the WLTC shall be correlated to the average Pm,j1 values calculated in accordance with paragraph 3.4. of this Annex B6b.
The best fit of the data shall be calculated using the least square regression method.
An example for this regression line (Veline line) is shown in Figure A6b /1.

Example of the Veline regression line.
3.7.
The vehicle specific Veline equation-1 calculated from paragraph 3.6. of this Annex B6b defines the correlation between CO2 emissions in g/s for the considered phase j and the average measured power at the wheel for the same phase j and is expressed with the following equation: MCO2,j = (kv,1 × Pm,j1) + Dv,1 where: MCO2,j is the average CO2 emission of phase j, g/s;
