Patent ID: 10317249

Abstract:
A method for determining the position θ of a moving part (T) along an axis (X), using an inductive sensor (10) including: a primary winding (B1) generating an electromagnetic field; a first secondary winding (R1), generating a first voltage signal (V1), of the sine function type; a second secondary winding (R2), generating a second voltage signal (V2) of the cosine function type; and a calculation unit (20′), wherein the method includes the steps of calculating and distributing linearization points i on the arctangent function tan(θ) resulting from the ratio of the first voltage signal to the second voltage signal, the linearization points i being distributed according to a sinusoidal function in order to reduce the error on the position (θ) of the target (T) at the ends (E1, E2) of the primary and secondary windings (R1, R2).
