Definition of the vehicle calibration factor
The vehicle calibration factor (sometimes also called the calibration constant) is a value that is used in a metrometer or measurement system to convert pulses or signals from speed sensors to distance.
In the case of a metrometer, the calibration factor is often denoted by the symbol “k.” It specifies the number of pulses or signals from speed sensors that are equivalent to one meter (or other unit of distance). For example, if the calibration factor is 1,000 pulses per meter, it means that for every 1,000 pulses from the speed sensor, one meter is traveled. The calibration factor is determined during the calibration of a metrometer, where distance measurements are taken along a known route or with other reliable measurement sources. Calibration allows the calibration factor to be adjusted to a specific vehicle and measurement system, which translates into accuracy and precision of measurement results. It is worth noting that the calibration factor can vary between different vehicles, even if they use the same model of metrometer. This is due to the individual characteristics and settings of each vehicle and the accuracy of the calibration performed.
In simplest terms and from a practical point of view, the calibration coefficient of a vehicle is the number of road pulses counted from the vehicle corresponding to the travel of 1000 m.
