  • the sum of the fuel mass burned over the life of the motor vehicle is typically stored in secured non-volatile memory at the end of each drive cycle. It can thus be ensured that the value of the fuel consumed calculated internally in the vehicle remains usable over the entire life of the vehicle. Nevertheless, this calculation results in significant Tolerances due to the influence of various components of a complete injection system.

  • One idea of the present method is therefore to improve the accuracy of the vehicle-internal calculation of fuel consumption and, if necessary, also the calculation of the tank fill level by using the value of the fuel quantity refueled overnight (here as referred to as “reference value”) is compared. Since fuel pumps are calibrated, their tolerances are defined as a maximum of 0.5% across the EU.
