Abstract
The invention relates to a device and a processing method for a camshaft sensor () of the type comprising a toothed camshaft wheel () and an opposite sensing element () able to detect a tooth front, comprising the following steps: detection of a new tooth front (k) by said sensing element; calculation of a rotational speed (Wk) of the camshaft wheel () for the new tooth front (k); comparison with the rotational speed (Wk−1) of the camshaft wheel for the preceding tooth front (k−1) detected by said sensing element; if the variation in the rotational speed (Wk) of the camshaft wheel () between the new tooth front (k) and the preceding tooth front (k−1) is low, the new tooth front (k) is validated, otherwise the new tooth front (k) is rejected.
