Abstract (en)
[origin: WO2017134366A1] The invention relates to a method for calibrating at least one pressure sensor positioned in an air intake line of an internal combustion engine, for which said at least one pressure sensor is calibrated with the engine stopped at an initial temperature (T1) by compensating the initial calibration (Cr(T1)) according to the equation Cr(T1)= Pcap(T1) - Pref(T1), the engine being stopped, Pcap(T1) being the measurement of pressure by said at least one pressure sensor, and Pref(T) the reference pressure, the measurement of said at least one pressure sensor being calibrated by the initial calibration compensation (Cr(T1)) thus calculated. With the engine running, at a given temperature (T), the calibration compensation (Cr(T)) is adjusted from said initial calibration compensation (Cr(T1)) depending on the temperature (T) of said at least one pressure sensor by a multiplying correction factor.
