摘要

Device for measuring torque applied to the rotating shaft, method for measuring torque, steering column and module to measure torque applied to the rotary axis.Device for measuring the torque applied to a rotating axis, notably to the steering column (2) of a vehicle, the device comprising a sensor element (1) deformable in torsion.The first and second means (5, 6) generating magnetic pulse associated with, respectively, in the vicinity of the first and second ends (3, 4) of the same.The first and second analog magnetic sensors (7, 8), and an electronic processing device (9) which, from the input analog signals a, B, C,What are the functions of the signals detected, to form the output signal f (a, B, C, d) = (b * c) - (a * (d)) / ((b * d) + (a * c), which is a function of the torque exerted on the shaft.The invention also includes a method of measurement of torque, a steering column and a module comprising such a device.
