In the context of the tachograph and the transmission, what technical term designates the number of revolutions or pulses per kilometer provided by the gearbox?

Question

DentroTest · Accepted Answer

For the tachograph to record speed and distance traveled accurately, it is essential to calibrate and relate three fundamental values: W factor (characteristic coefficient of the vehicle): It is the numerical characteristic that expresses the number of pulses or rotation revolutions produced by the gearbox output shaft when the vehicle travels a standardized distance of one kilometer (pulses/km or rev/km). K factor (tachograph constant): It is the value specific to the tachograph device that defines the number of input signals it needs to receive to compute and record one kilometer traveled. L value (perimeter): It represents the effective circumference of the tires of the driving wheels, measured under standard load and pressure conditions. Therefore, the revolutions per kilometer of the gearbox are unambiguously identified with the W factor.
