2) Driver Demand
The driver demand is the translation of the pedal position into the fuel demand. It is calculated
as a function of the pedal position and of the engine speed. The driver demand is filtered in
order to limit the hesitations caused by rapid changes of the pedal position. A mapping
determines the maximum fuel which can be injected as a function of the driver demand and the
rail pressure. Since the flow is proportional to the injection time and to the square root of the
injection pressure, it is necessary to limit the flow according to the pressure in order to avoid
extending the injection for too long into the engine cycle. The system compares the driver
demand with this limit and chooses the smaller of the 2 values. The driver demand is then
corrected according to the coolant temperature. This correction is added to the driver demand.
