The invention relates to a method for identifying edges on a camshaft target (30) having a plurality of teeth on the periphery thereof, the plurality of teeth forming a series of M edges when the camshaft makes one revolution, wherein said method includes the steps of: for each of the M edges, computing the characteristic P(i) denoting the angular distance between the edge i and the preceding edge; when the camshaft target is moved, computing, upon the detection of an edge, an index T(i) indicating the time that has elapsed from the occurrence of the edge i-1 until the edge i; comparing the index CT(k) to each CP(j); and determining the position of the camshaft. |
