| Summary: | The calibration process according to the invention, intended for a pneumatic-assistance servomotor for a braking circuit of a motor vehicle, consists in measuring and recording, on the basis of a given negative-pressure value (Pfc) inside the negative-pressure chamber of a servomotor, the values of the output pressure (Pmc) of the hydraulic master cylinder associated with said servomotor, and of the negative pressure inside the working chamber of the servomotor, for several operating points P

of the servomotor, located on either side of the saturation point so as to determine the coordinates of the saturation point precisely, for an accurate control of the advanced functions, as concerns the braking operation, the braking assistance and/or the monitoring of the performance or of the ageing of the servomotor. |
