Abstract
A method of detecting a reference zone formed on the periphery of a toothed disk integral with a rotary part, for determining the angular position of the rotary part. According to this detection method, when a reference zone is expected and at the time of the detection of a tooth (n) at a time t, there is defined a time window [tmin, tmax] of duration depending on the time period Tseparating the detection of the tooth (n) and the detection of the preceding tooth (n−1), and the reference zone is considered present in the absence of detection of a tooth (n+1) during the time window [tmin, tmax]. Moreover, the duration of each time window [tmin, tmax], calculated from a measured time period T, is adjusted by modulating that duration by a correction parameter equal to ΔT=T−T.
