The invention relates to a method for processing a signal of a pressure measuring device inside an internal combustion engine, said device comprising: a pressure measuring sensor outputting a voltage signal (SB); and a processing unit connected to said pressure measuring sensor. According to the invention, the method comprises the following steps: I. calculation of a duration (Dt1) between a first instant (t0) corresponding to a first combustion peak pressure (P0) and a second instant (t1) corresponding to a second combustion peak pressure (P1), following the first combustion peak pressure (P0); II. calculation of a correction initiation instant (tc1) defined according to the previously calculated duration (Dt1); III. measurement of a value of the signal (VOFF1) at the time of the correction initiation instant (tc1); and IV. correction of the signal, from the correction initiation instant (tc1), in relation to a reference value (VREF), and generation of a first processed signal (S) such as S = SB— VOFF1 + VREF. |
