03/12 EM-ABS-01 for ACU 39
With the example values, the following results are obtained:
Preliminary Numerator = 32.
Preliminary Denominator = 27.7336.
The values calculated in this way can be used directly for parameters
EC2 Gear Fac-
tor Numerator
513 and EC2 Gear Factor Denominator 514. To increase accuracy,
the following intermediate “Optimization” step is recommended. This intermediate
step is not necessary if accuracy is already sufficient.

the accuracy. The
check is not required for proper function, it is solely for determining the accuracy lim-

Due to rounding operations in the parameters described above, there will be an error
across the total travel distance. This error is calculated in the following steps:
