Abstract (en)
[origin: EP1469197A1] The method involves measuring a current intensity (Ici) of an inductive circuit, in last tenth of a preset conduction time (tdi). Current intensity (Ifi) at the end of the time (tdi) is estimated based on the intensity (Ici). The time (tdi) is corrected for an ignition cycle during which a last intensity is measured based on the estimated intensity and a desired current intensity (Ii) at the end of the time (tdi).
