Abstract

Le procédé concerne la détermination de points d’appui en régime moteur pour une calibration d’un moteur thermique, le moteur thermique comprenant au moins un actionneur ayant une influence sur la calibration, Conformément à l’invention, le procédé comprend des paliers de calage successifs (P1_AAC à P3_AAC, R1_PDA à R4_PDA) du au moins un actionneur à des positions fonctionnelles fixes et un balayage (BL3) du régime moteur dans un mode dynamique, le balayage (BL3) s’effectuant selon une rampe de régime moteur allant d’un régime moteur minimum (Nmin) à un régime moteur maximum (Nmax) et avec un pas de rampe (PR) ayant une valeur prédéterminée. Fig.4The method concerns the determination of support points at engine speed for a calibration of a heat engine, the heat engine comprising at least one actuator having an influence on the calibration. In accordance with the invention, the method comprises calibration bearings successive (P1_AAC to P3_AAC, R1_PDA to R4_PDA) of the at least one actuator at fixed functional positions and a sweep (BL3) of the engine speed in a dynamic mode, the sweep (BL3) taking place according to an engine speed ramp ranging from a minimum engine speed (Nmin) to a maximum engine speed (Nmax) and with a ramp step (PR) having a predetermined value.
