METHOD FOR DETERMINING THE ANGULAR POSITION OF A TOOTHED TARGET WHICH IS ROTATABLY SECURED TO A SHAFT OF AN INTERNAL COMBUSTION ENGINE

Disclosed is a method for determining the angular position of a toothed target which is rotationally secured to a shaft of an internal combustion engine. The method is based on dynamically determining a ratio between the different periods measured between the teeth of the target. Comparing the ratio with a threshold value allows identification, where appropriate, of an angular reference zone around the periphery of the toothed target.
