Abstract

A method for processing a voltage signal relating to the pressure prevailing in a combustion chamber of a cylinder of an internal combustion engine, the signal, referred to as an 'input signal', having, in alternation, 'plateau' phases and main peak phases. The method includes a step (E) of rectification of the input signal such that the gradient of the base signal is zero, a step (E) in which the peaks of the rectified signal of which the amplitude is greater than a predetermined voltage value are clipped so as to obtain an at least partially clipped signal referred to as a 'clipped signal', a step (E) of detection of a main peak when the amplitude of the input signal is greater than the amplitude of the clipped signal, and a step (E_, E_) of compensation of the input signal in the absence of such a detection.
