Abstract
Disclosed is a method for determining the angular position of a shaft by a sensor including a toothed wheel including p teeth distributed at equal angles and an additional tooth and a sensitive element that is able to detect a tooth, including the following steps: receiving a tooth signal and the date thereof; shifting the preceding time intervals: Tn−3←Tn−2, Tn−2←Tn−1, Tn−1←Tn; determining the current time interval according to the formula Tn=tn−tn−1; calculating a ratio according to the formula Rn=(Tn*Tn−3)/(Tn−1*Tn−2); and comparing the ratio with a threshold, if the ratio is greater than the threshold, the current tooth signal corresponds to the second tooth immediately following the first tooth, itself immediately following the additional tooth.
