Method for adapting to the tolerances of a system comprising a position sensor and a rotating target

Abstract

A method for adapting to the tolerances of a system including at least one position sensor and a rotary target. When the target rotates, the sensor(s) detects (detect) a predefined singularity on the target at an instant T_i, including: acquisition of a series of n+1 instants T_0 to T_N corresponding to a rotation R of the target; determination of theoretical values Theo_i for each instant T_i while considering that the time corresponds to the time that the target takes to effect the rotation R, taking account of any acceleration during the rotation R and as a function of a position of the predefined singularities on an ideal target produced without tolerance; conversion of the time difference between Theo_i and T_i into an angular difference A_i for a corresponding singularity of the target detected by a sensor; and memory-storage of the angular differences A_i for each singularity of the target.
