Abstract
A processing method of an alternating signal produced by a variable reluctance sensor, including steps consisting of a raw window signal switching toward a low voltage level, respectively toward a high voltage level, calculation of a processed window signal using a value of the switching continuation duration calculated as a function of a value of shaft rotation speed, and based on the raw window signal, measurement of the shaft rotation speed, each switching of the processed window signal triggering the locking of the processed window signal, for a duration exactly equal to the switching continuation duration, so that the switches of the raw window signal are not translated into switches of the processed window signal during the locking, the processed window signal no longer being locked once the switching continuation duration has expired.
