Abstract
A method for automatic calibration of a camshaft sensor for a motor vehicle, allowing reduction of the fluctuations on the output signal of the sensor. The method proposes comparing, on each target rotation, the new maximum values of the magnetic field of each tooth to the maximum values of the same teeth from the preceding target rotation. The switching thresholds are only calculated with the new maximum values if these differ from the maximum values of the preceding target rotation. Moreover, the invention proposes using a single minimum value of the magnetic field, i.e. the absolute minimum value on a target rotation in order to calculate the switching thresholds.
