PCT No. PCT/EP93/00627 Sec. 371 Date Sep. 19, 1994 Sec. 102(e) Date Sep. 19, 1994 PCT Filed Mar. 17, 1993 PCT Pub. No. WO93/19293 PCT Pub. Date Sep. 30, 1993.The instantaneous energy of the pinging phenomenon is measured, a quantity (Ri) dependent on the instantaneous value of this same measurement is calculated, a sliding average value (Rm) of the quantity (Ri) weighted by a forget factor is calculated and a correction (RA) of the ignition advance angle is calculated from an inference engine marshalling "fuzzy" logic rules enabling the membership class of (Ra) to be established from those of (Ri) and of (Rm).
