Abstract[English]
The present subject matter provides a method and a system for normalizing position of a piston. The method is implemented by an ISG controller (103B). The method comprises receiving a first signal indicating position of piston (102A). The method further comprises receiving a second signal indicating switching off of engine (102). The method further comprises estimating a position of the piston (102A) at first time instant when engine is turned off. The method further comprises determining position of piston and if position of piston in vicinity of a top dead center then performing forward motoring based on estimated position of piston at first time instant.[French]
La présente invention concerne un procédé et un système de normalisation de la position d'un piston. Le procédé est mis en œuvre par un contrôleur ISG (103B). Le procédé consiste à recevoir un premier signal indiquant la position du piston (102A). Le procédé consiste en outre à recevoir un second signal indiquant l'arrêt du moteur (102). Le procédé consiste en outre à estimer une position du piston (102A) à un premier instant auquel le moteur est éteint. Le procédé consiste en outre à déterminer la position du piston et si la position du piston à proximité d'un point mort haut effectue ensuite un entraînement vers l'avant sur la base d'une position estimée du piston à un premier instant.
