Abstract (en)
[origin: ES8300181A1] An ignition coil control device output stage of a calculator (2) has a transfer function of the form: tc=N.TSD+ epsilon where epsilon is a small and known quantity tc is the conduction time of the coil, N is a number of angular fractions or periods of an interpolation signal and TSD is the period corresponding to one tooth on the starter gear. The device comprises measurement means (1, 32, 36) for measuring the time strictly necessary to obtain the required energy means (6, 9, 13, 17) for generating signals at each fraction of the angular marking signal in order to obtain a time measurement of a counting window and means (21, 25, 29) for counting and memorizing during this window an interpolation signal of the angular resolution n times higher.
