Abstract
Method for determining the position of a magnetic element on a gearbox selector of an automobile, generating a magnetic field ({right arrow over (V)}), the speed selector moving in two directions with respect to a longitudinal axis, a main direction and a secondary direction, the magnetic element facing a position sensor including three Hall effect cells, includes measuring three voltages (V1, V2, V3) at the respective outputs of the three Hall effect cells oriented in the same direction and positioned as follows: two cells being aligned on a transverse axis perpendicular to the longitudinal axis, the third cell being positioned on the longitudinal axis perpendicularly to the transverse axis, passing through the other two Hall effect cells,
