Beschreibung
Zusammenfassung:The method involves estimating a control voltage by estimating indicated average torque from characteristic quantity of rotation movement of an engine (2). The engine has an angular position sensor (16) delivering an alternative frequency signal proportional to unwinding speed of patterns of a target opposite to sensible element fixed at an engine block. The angular position sensor is operated by magneto-reluctance. L'invention concerne un procédé de correction des dérives des injecteurs d'un moteur de véhicule, comprenant une étape d'estimation de la tension de pilotage (Ui), caractérisé en ce que cette estimation est réalisée en utilisant au moins une estimation du couple moyen indiqué (Ci).
