An adjusted road load curve for the test vehicle L is defined as follows:
              Applying the least squares regression method in the range of the reference speed points, adjusted road load coefficients  and  shall be determined for  with the linear coefficient  set to . The road load coefficients ,  and  for an individual vehicle in the interpolation family shall be calculated using the following equations:
              or, if  = 0, the equation for f0,ind below shall apply:
              or, if , the equation for F2,ind below shall apply:
